We propose that the ability of humans to identify and create patterns led to the unique aspects of human cognition and culture as a complex emergent dynamic system consisting of the following human traits: patterning, social organization beyond that of the nuclear family that emerged with the control of fire, rudimentary set theory or categorization and spoken language that co-emerged, the ability to deal with information overload, conceptualization, imagination, abductive reasoning, invention, art, religion, mathematics and science. These traits are interrelated as they all involve the ability to flexibly manipulate information from our environments via pattern restructuring. We argue that the human mind is the emergent product of a shift from external percept-based processing to a concept and language-based form of cognition based on patterning. In this article, we describe the evolution of human cognition and culture, describing the unique patterns of human thought and how we, humans, think in terms of patterns.
Keywords:patterns; patterning; cognition; set theory; language; information; abductive reasoning
Humans both deal with information and engage in creative thinking, while computers only process data according to the instructions of their human programmers. We believe humans are capable of both recognizing and creating patterns, but computers are only capable of recognizing the type of patterns that they have been programmed to look for. We believe computers are deduction engines that are also capable of induction, as is the case when they succeeded at mastering chess or Go. They are not capable of abductive reasoning or creating a story, however, and hence there are limits to their creativity. Abductive reasoning is a form of logical inference using imagination, in which the simplest and most likely hypothesis is posited to explain observed phenomena (see Peirce ). The claims made in this opening paragraph are argued for in the lead paper of this special issue by Braga and Logan . The purpose of this paper is to provide background on human cognition (and cognition in general) for the debate of human versus computer cognition.
In Braga and Logan , the authors claim that the technological Singularity, the idea that through AI, certain computers will be able to create a level of intelligence greater than that of humans, is not possible because computers are not capable of abductive reasoning, imagination and creativity. We will argue in this article that patterning is an essential feature of human cognition and is a product of abductive reasoning and imagination, which are features that computers are not capable of. This article therefore supports the claim of Braga and Logan  that the hypothesis of the eventual emergence of the Singularity is not correct.
We believe that ability to recognize and create patterns led to the unique aspects of human cognition and culture. This shift led to the co-emergence of inter-related traits, all characterized by their ability to manipulate and restructure patterns, via mathematics, verbal language, imagination and abductive reasoning. Since imagination is a form of abductive reasoning and abductive reasoning is a form of imagination, we will pair the two notions as imagination/abductive reasoning for the purpose of discussing patterning in this article. Our justification for the pairing of abduction and imagination is that one of the definitions of abduction is the process whereby one finds the simplest and most likely explanation of what one has observed and it is imagination that enables one to carry out this process.
We also believe that the environmental pressure of information overload is a key factor in our proposed dynamic cognitive system of human intelligence, which drives us to continuously create media and technologies to be able to not only efficiently process patterns, but also to reconfigure patterns in novel ways. What led to this huge cascade of complex ways of manipulating and restructuring patterns at the dawn of homo sapiens? We propose, as an abduction, that these complex forms of pattern-structuring, namely mathematical, linguistic and creative thinking, bootstrapped themselves into existence via the human ability to simultaneously hold multiple parallel representations in both mind (online) and memory (offline), allowing us, with a greater representational sandbox, to continuously structure and restructure patterns in countless ways. How patterns become instantiated in culture will also be explored.
As hinted at by our title, we believe that the ability to recognize and create patterns is the key to understanding the nature of human cognition and culture as well, as specifically, uniquely human traits, namely the control of fire, the ability to deal with information overload, patterning, primitive set theory, verbal language, imagination, abductive reasoning, invention, art, religion, mathematics and science, are all interrelated. We have tried to order the description of these factors that make us humans unique more or less in the order in which they emerged. We say more or less because some developed or emerged simultaneously and their interrelationships are non-linear and are part of emergent dynamics. The narrative we are about to develop is a story, an abductive reasoning or simply just a guess of how we humans came to be this super intelligent being that we are. This story is not represented as science, since there is no way to test the validity of our conjectures, but we believe that it might provide some insight into the relationship between the unique features of the human modus operandi.
Our story begins with the ability of the genus, Homo, to control fire, which led to a new social structure of large numbers of people living together and in turn led to information overload and the need to co-ordinate the activities of a large group of people. The solution to deal with the information overload was the emergence of verbal language, which required patterning in the form of set theory, in which words acting as concepts represented all of the percepts related to each of those words/concepts. Verbal language had a transforming effect and made possible imagination/abductive reasoning, which in turn gave rise to new technologies, mathematics, science, artistic expression and religion. The set of relationships that we have just outlined and presented are by no means obvious, but we hope to convince you in this article that these characteristics of human cognition and culture are interrelated. The narrative we have just presented is linear, but the relationships among these elements that make us humans unique is by no means a linear one. The evolution of human culture is a story of a complex adaptive system, in which emergent dynamics are always the driving force of this evolution. As we develop our narrative, some elements will appear twice, given the non-linear nature of our subject and the linear nature of our medium of the written word. To further support some of our claims, we will draw from various neuroscience designs that shed light on some of the pattern-processing and restructuring tools implemented in our brains.
The environmental pressure of our proposed dynamic system is information overload, which drives us to continuously create technologies and media to be able to not only efficiently process patterns, but also to reconfigure patterns in novel ways. What led to this huge cascade of complex ways of manipulating and restructuring patterns at the dawn of homo sapiens? We propose that these complex forms of pattern-structuring, namely mathematical, linguistic and creative thinking, bootstrapped themselves into existence via the human ability to simultaneously hold multiple parallel representations in both mind (online) and memory (offline), allowing us, with a greater representational sandbox, to continuously structure and restructure patterns in countless ways. How patterns become instantiated in culture will also be explored. We will examine math, language, artistic and scientific thinking and imagination/abductive reasoning, as tools by which we process and restructure information to best suit our goals.
2. Human Control of Fire and the Ensuing Information Overload It Created
Faced with information overload, we have no alternative but pattern-recognition—Marshall McLuhan (, p. 132).
The human control of fire changed the way our human ancestors lived together. Before learning how to control fire, humans lived in nuclear family units consisting of the mother, the father and their non-adult children. As the children grew into adulthood they went off and formed their own nuclear families and hunted and gathered on their own so as not to interfere with their parent’s food gathering activities (, Chapter 3; , p. 60).
With the control of fire, nuclear families banded together to form clans of related nuclear families to take advantage of the many benefits that fire offered such as (i) warmth, (ii) protection from predators, (iii) tool sharpening, and (iv) cooking, which increased the number of plants that could be made edible, killed bacteria and helped to preserve raw foods, such as meat. Living together in clans gave rise to new, more complex and larger social structures that bred a form of information overload because of the increased complexities of social interactions and the need to organize the activities of many people to gather food and to maintain the campfire.
This information overload of interacting with many people and carrying out more sophisticated activities led to the need for better communications to better co-ordinate social transactions and co-operative activities, such as the sharing of the benefits of fire, the maintenance of the hearth, food sharing, and large scale coordinated hunting and foraging. Communication in this new environment became essential, and it is, therefore, surmised that this gave rise to a new preverbal proto-language of social interactions that emerged with the proto-semantics of social transactions, which included greetings, grooming, mating, food sharing, and other forms of co-operation appropriate for clan living. The proto-syntax of social organization or intelligence included the proper ordering or sequencing of these transactions in such a way as to promote social harmony and avoid interpersonal conflict, and, hence, contribute to the survival and development of hominid culture. It was in this environment that verbal language emerged with a still more complex level of organization.
The mechanism by which verbal language emerged was that words acting as concepts came to represent all of the percepts associated with that particular concept. Reflecting the transition from external to more internal pattern-processing, language emerged as the transition from percept- to concept-based thinking, according to the thesis developed in the book The Extended Mind: The Emergence of Language, the Human Mind and Culture . A word acts as a concept that connects all of the percepts related to that word. The use of a word like “water”, representing the concept of water, triggers instantaneously all of the mind’s direct experiences and perceptions of water, such as the water we drink, the water we cook with, the water we wash with, the water that falls as rain or melts from snow and the water that is found in rivers, ponds, lakes, and oceans. The word “water” also brings to mind all the instances where the word “water” was used in any discourses in which that mind participated either as a speaker or a listener. The word “water”, acting as a concept and an attractor, not only brings to mind all “water” transactions, but it also provides a name or a handle for the concept of water, which makes it easier to access memories of water and share them with others or make plans about the use of water. Words representing concepts speed up reaction time and, hence, confer a selection advantage for their users. At the same time, those languages and those words within a language which most easily capture memories enjoy a selection advantage over alternative languages and words, respectively. Before humans had verbal language, the brain was a percept processor, but with language the brain became a mind that was capable of conceptualization and the ability to plan. The mind is the brain plus language.
Several experimental studies have found that providing labels (i.e., a word) facilitates the learning of categories, i.e., seeking patterns ([6,7]). In fact, a word acting as a handle of a concept can even override more perceptual category learning , further suggesting that human cognition does represent a shift away from only bottom-up learning, towards more top-down, internal representations and the manipulative restructuring of our world. Such restructuring becomes easier to facilitate and more graspable when you have a handle.
The mechanism that actually led to verbal language seems to have involved the ability of humans to create patterns by distinguishing set of objects or activities that are similar and differentiating them from other objects or activities. It is in this sense that mathematics, in the form of set theory, emerged. Logan and Pruska-Oldenhof , in a book entitled A Topology of Mind – Spiral Thought Patterns, the Hyperlinking of Text, Ideas and More, developed the thesis that “the human mind is intrinsically verbal and mathematical and that language and mathematical thinking co-emerged at the dawn of the emergence of Homo sapiens.” They posited that the origin of mathematics in mind occurred in the form of the classification or the grouping of like things into sets or groups and giving a name to that set or group, namely a word, acting as a concept, used to represent that set of percepts. It is the same skill that eventually gave rise to modern set theory and group theory and, as they claim, preceded the skill of counting or enumeration and actually laid the foundation for it. Therefore, linguistic and mathematical thinking both seem to play an important role in how we process and manipulate patterns.
Further support for the notion that the human brain is intrinsically mathematical, and that this mathematical feature is highly intertwined with our linguistic abilities, is observed through the phenomenon of statistical learning. Statistical learning is the ability to extract complex regularities and patterns from our environments over time . Infants, for instance, are remarkably good statistical learners. An infant can effectively learn what phonemes occur together in a sentence over time by implicitly picking up on the transitional probabilities of sounds . This remarkable ability to pick up on patterns, that is, how elements of experience relate, is argued as the reason for infant’s and children’s remarkable ability to learn language. Indeed, it is this mathematical quality of the mind that actually allows us to learn and implement complex linguistic structures or patterns. This further suggests that mathematical and linguistic thinking are tightly intertwined. Equally as remarkable is not only the brain’s ability to pick up on the transitional probabilities described above (i.e., what features frequently co-occur together), but also to form even more complex mathematical representations in mind, such as forming distributional probabilities of categories, where through exposure to exemplars, the brain is able to integrate these experiences to create a “prototypical representation or distribution (ibid.).”
What pattern-processing mechanisms are involved in statistical learning? One account of statistical learning suggests a two-step model, whereby patterns must be extracted and then integrated  Again, this type of model parallels our thesis that pattern-processing is not computationally uniform, but a dual-process of pattern-processing, whereby one involves the ability to perceptually pull out patterns (pattern-recognition) and the other to integrate them into a broader picture (which we call pattern-restructuring). For instance, when we are learning a category, this involves (1) noticing what features co-occur together (in a statistically reliable way), and (2) integrating them to form a more generalized group and an integrated and abstracted representation of the category (for example, a prototypical exemplar of what is a “cat”). This process of integrating and restructuring is essentially equivalent to creating “new information”. In sum, we have argued that the mathematical properties of the mind and language are tightly intertwined. By feeding off each other, they likely played a role in the very fast, snowballing cognition of homo sapiens, with mathematical thinking pushing us to create sets and patterns, and linguistic thinking making it easier for us to integrate or bundle things together into these sets (i.e., a word acting as an anchor or attractor for multiple percepts). Mathematical thinking, then, acts as a tool to manipulate information into patterns, and language acts as the handle, making them easier to grasp.
Thus, we agree with McLuhan that pattern-recognition is, in fact, how we successfully deal with information overload, and pattern-restructuring is how we can use large amounts of information for our advantage. For instance, evidence that we are able to manipulate patterns to create categories that best suit our needs is seen in cross-cultural differences in categorization. An additional argument to more strongly support the claim that there are variations within sets, based upon the pressures of the environment, was pointed out by Unsworth et al. , in regard to the cross-cultural differences in the categorization of butterflies. In reference to past anthropological studies, these authors pointed out that in the Fore culture, there are very well-defined, rigid, and discriminated sub-categories of birds because birds held hunting value as food and, therefore, it was important to make very discrete sets about them. Diamond , however, pointed out that this culture lacked any of these discrete, distinctive sub-groupings for butterflies, because butterflies, unlike birds, held little tangible value to this culture. Unsworth et al.  then went on to compare this culture to the Tzeltal culture who also did not have discriminate categories for butterflies, but did for butterfly larvae, which they used as a food source and encountered as a threat to crop growth . In other words, the value and role of an organism to a society changes how categories are created or how we want to structure and differentiate information. Thus, this anthropological example is a fascinating example of how the patterns that we focus on to create categories may vary based on their impact or lack of impact on our culture.
As a result, the human mind requires the scaffolding to be able to accommodate the flexible nature in which we create sets. Pattern-processing, the ability to process incoming information, is not enough, but we require the ability to flexibly use and manipulate this information to best suit our goals and our understanding of our environment.
3. The Co-Emergence of Math and Language: The Shift from External Pattern-Recognition to Internal Pattern-Restructuring
What kind of mental faculties differentiate human cognition from that of animals? What cognitive qualities make us uniquely human? In answer to these sorts of questions, Charles Darwin humbly stated that “the difference in mind between man and the higher animals, great as it is, certainly is one of degree and not of kind.” Do our pattern-processing abilities then only reflect a difference in degree and capacity? Explicitly drawing from this quote, Mattson  echoes Darwin’s idea and draws from a vast range of animal research to argue that the human brain is a result of its superior pattern-processing abilities and not necessarily any difference in the kind of these processes. Indeed, several studies have found “scaffolding” or more proto-cognitive abilities in higher primates, that do seem to only differ in terms of a difference in degree.
However, while we agree with Mattson  that increasingly complex and superior pattern-processing is a crucial hallmark of the human mind, we argue, however, that there may be some cognitive qualities that cannot be scaled or reduced down to the level of higher primates, as they are the product of emergence, which, by definition, cannot be reduced down to its individual parts. In fact, reducing certain human properties of cognition down to the “same” or a difference in degree may overlook many of the important qualities that make us human. Echoing this view, Cobley  argues that the entire field of biosemiotics radically “insists that humans are separated from other organisms by a difference in kind and a difference in degree.” Others who also study dynamic systems and the emergent properties of such systems also view kind and degree similarly, and not as oppositional processes, whereby emergence is the process by which “a difference in degree becomes a difference in kind ”. When do we draw the line of when a difference in degree becomes so different that it appears more appropriately as a difference in kind? This transition has been described as a quality of emergence, whereby “a difference in degree becomes a difference in kind”. While the difference in degree of our remarkable ability to process patterns is undeniable, the hallmark of the human mind does appear, then, to be one of a difference in kind, rather of degree.
Instead of arguing that human cognition is superior only because we are just really good at pattern-processing in general (i.e., a difference in degree), we believe there is value in further breaking down what constitutes pattern-processing and what kinds of patterning humans particularly excel at. We will look at (1) pattern-recognition, or the ability to perceive and extract patterns from our environments, as well as (2) pattern-restructuring, or the ability to manipulate these patterns internally to create new patterns. Pattern-recognition is how we cope in a world of information overload, and pattern-restructuring is how we transcend it and create new information. It is in the latter kind of pattern-processing that humans excel, that is, the ability to flexibly manipulate patterns to suit our goals. We also suggest that this ability led to several uniquely human phenomena such as science, religion, and art. We argue that human cognition, as seen with mathematical, linguistic, scientific and imaginary thinking, represents a shift towards more pattern-restructuring based cognition and, thus, the hallmark of the human mind reflects a difference in degree and of kind.
4. The Nature of Patterns
Patterns paradoxically both unify and divide our world. It is through this process of differentiation, of grouping things that are similar from those that are dissimilar, that we are able to meaningfully extract information. We will argue that a crucial hallmark of human pattern-processing is the ability to flexibly manipulate patterns and restructure them in novel ways to best suit our goals. First, we will explore the concepts of information and patterns, and how patterns give rise to information. Then, we will explore pattern-processing in the context of the human mind and in terms of mathematics, language, science, social science, the arts and imagination/abductive reasoning, for the creation of cognitive tools.
5. What is Information? Forming a Pattern is Equivalent to Creating Information
This leaves us with the question of: How was it that humans were able to create the patterns for grouping things into sets of objects or activities that possess similar properties? Marlie Tandoc, in an independent study course supervised by Robert K. Logan, built upon the idea of a topology of mind and mathematics in mind by introducing the notion of “a set theory of mind”, according to which a category or a set is the most basic form of information. Categories or sets can vary by their content and the way in which the elements of the category or set relate to each other.
What forms a pattern? It is paradoxical that the similarity of the elements of a set creates a difference between the very elements of the set and all of the things not in the set. Creating or defining a set automatically creates another set, which we will call the anti-set, consisting of all things not in the original set. Since information is a difference that makes a difference, according to Gregory Bateson , p.428, creating a pattern is equivalent to creating information. Without similarities there are no differences, because once one sees similarities it causes one to consider things that are not similar and, hence, different. Difference is merely the absence of similarity, just as zero is the absence of a number and dark is the absence of light.
We would like to propose that difference arises as a natural emergent property of similarity. Each time we make a similarity judgment, we automatically draw a boundary and everything outside that boundary is different. Thus, information can be defined as the process of this emergence of differences, created by making similarity comparisons. The idea that information should be viewed not as a noun, but as the verb of informing , follows from this idea that information should be studied as a process. If information is a difference that makes a difference according to Bateson , then it can also be said that information is a non-similarity that makes a non-similarity.
Imagine having apples and bananas randomly spread out in front of you and drawing a circle around all the apples. While we may have the intent of drawing a circle to enclose whatever is inside (i.e., these items are all similar in color and shape), a circle also creates a boundary to everything outside of it, that is, all the bananas (the anti-set). Similarly, a judgment of similarity, thus, naturally creates a judgment of a difference, and the byproduct of this process is what we call information. Therefore, there can be “no difference without similarity”  and vice versa.
Many times, while we do make similarity comparisons, differences seem to quite literally “pop out at us.” For instance, in a visual search process, items that are different, particularly that only vary in one dimension, such as color, seem to perceptually “pop out” at us. This automaticity and perceptual salience is the power of the information as a difference and as an emergent property of similarity.
Similarity is the fundamental pattern processing tool of human cognition and difference is what emerges from its use. For instance, one empirical study found that children were only able to learn by comparing within-category similarities, whereas adults were able to learn categories from both within-category similarities and between-category differences . This suggests that similarity comparisons may develop before differences. “Similar” is easier to see and process than “not-similar” or “different”, just as it is easier to conceive of positive integers than it is to conceive of zero and negative integers. The ancient Greeks and Romans were able to conceive of positive integers but not of zero or negative integers.
We can view similarity as the absence of difference and eliminate one of the terms from our analysis and use similar and non-similar or different and non-different. It is easier for us to process and recognize less differences than it is for us to see more differences.
Identifying similarities is a form of pattern recognition and pattern recognition, in turn, is a way of dealing with information overload, as pointed out by Marshall McLuhan , p. 132: “Faced with information overload, we have no alternative but pattern-recognition.” Recognizing similarities to create a category or a set also leads to the construction of words, and words in themselves are another way of dealing with information overload. As noted above, the emergence of verbal language was motivated by the information overload of humans living in close quarters around the campfire.
Creating a category involves making a generalization, with the result that the greater the specificity of the category or the set, the less general or encompassing it is. But, on the other hand, the more general the category, the less specificity it possesses. The four categories of i. living organisms, ii. animals, iii. dogs, and iv. cocker spaniels increase in their level of specificity but decrease in their order of generality. In other words, the more specific the similarity, the smaller the set or the less general it is. The complementarity of generality and specificity of categories parallels the complementarity of position and momentum in the Heisenberg uncertainty principal in quantum mechanics, which states that the more you know of an atomic particle’s momentum the less you know about its position and vice-versa. We call the complementarity of specificity and generality of categories the LT uncertainty principle of generalization and specificity. The greater the scope of the generalization of a category, the less its specificity and the greater its specificity the less its generalization. It is a trade-off because you cannot have both. More generalized categories allow us to make more comparisons across a wider range of experiences, at the cost of losing specificity, i.e., there are less similarities between the elements of the category. With more specific categories, more similarities exist between the members of the category but the number of members is less than is the case with a more generalized category.
Is there a sweet spot? Words for basic-level categories such as dog, tree, flower, or bird are found in nearly all languages and cultures and have shown strong perceptual, learning and memory biases for this level of category . Basic categories, instead, may be the most effective level that allows for an informational sweet spot of generalization and specificity, and, thus, acts as an adaptive mechanism for information, which evolved over time and converged as the easiest to learn. Over cultural evolution, the level of generality and specificity in words and categories that have come to “stick” may, thus, represent the most effective level of generality versus specificity in our linguistic environments.
Nonetheless, certain environmental or task demands may push us towards creating more general or specific categories. Evidence for this is that information-processing is highly relativistic, and the benefit of basic level categories can just as easily vanish as they seem to appear. In a case where you are moments away from a tiger about to pounce, the most valuable piece of information may be something more general, such as predator or prey, rather than the exact species of the tiger. For example, while basic level categories (such as that of bird, tiger, or bear) typically show the greatest perceptual advantage in category learning tasks when time is limited (~30 milliseconds) and you have less time to make a decision, generality wins over specificity in that you “spot the animal before you spot the bird .” These findings support that when time is short, you might see a predator before you see a Siberian Tiger. However, in cases when you have more time to make a decision, a higher level of specificity may be of more benefit. Vervet monkeys, for instance, have different signals for different types of predators, which allows them to take the best course of action for that specific type of predator. In summary, in this example, time to make a response and context play a role in which categories one tends to rely on. This further supports the notion that decision-making based on categories is highly dependent on context, in this case the time to make a response, underscoring the relativistic nature of information.
Tradeoffs between the general and the specific have become a huge area of interest for neuroscientists in complimentary learning systems theory. The two complimentary learning systems include (1) the ability to integrate information across different experiences, and (2) the ability to code for episodic specificity of individual experiences .
It makes sense that having a good sense of what a “chair” is (similarities), is necessary information to know how a “chair differs from a table” (differences). Similarly, facing a new and uncertain world, similarity knowledge may be more flexible in its capacity for novel comparisons. Only memorizing an optimized rule of how a chair is different than a table may not be that helpful when later having to differentiate between a chair and a couch. Instead, knowledge of the internal properties of the features likely to co-occur across chairs may be much more helpful, at least at first. Indeed, it may be advantageous to initially bias the system towards internal similarities, as this, in turn, can allow us to later use these similarities to bootstrap ([18,25]) diagnostic differences into existence and to do so across a wide range of contexts.
In summary, we have argued that biasing attention towards similarities, as the crux of pattern-processing, is beneficial, as it (1) constrains the meaningful differences to emerge (as information), and (2) allows more flexible use of this information for novel comparisons.
6. Letting Go: Pattern-Restructuring as the Mechanism of Novel Ideas, Language and Imagination
“The spoken word was the first technology by which man was able to let go of his environment in order to grasp it in a new way.”—Marshall McLuhan.
Language, imagination, abductive reasoning, invention (as in technology), art, religion and science are unique characteristics of humans that no other animals possess and seem to be related to each other, as we will claim, and this idea is supported by a number of other scholars that will be referenced in this section.
Marshall McLuhan and Robert K. Logan  wrote:
If one must choose the one dominant factor which separates man from the rest of the animal kingdom, it would undoubtedly be language. The ancients said: ‘Speech is the difference of man’… It is the medium of both thought and perception as well as communication.
A number of authors have made a connection between language and imagination. Among these are:
Daniel Dor , author of the book, “The Instruction of Imagination: Language as a Social Communication Technology”, characterizes “language as a functionally specific communication technology, dedicated to the instruction of imagination: with language, and only with it, speakers can make others imagine things without presenting them with any perceptual material for experiencing.”
Eric Reuland, author of the articles, “Imagination, planning, and working memory: the emergence of language ” and “Language and imagination: Evolutionary explorations ”, shows the intimate relationship between language, imagination and planning. He argues that language makes imagination possible  where he explores the relation between imagination, planning and language. He  also claims that imagination is “the language lab, producing both science and poetry”.
Paul Crowther ), author of “Imagination, language, and the perceptual world: a post-analytic phenomenology”, argues “that language directs imagination, empirically speaking in adult life, but that the ontogenesis of language presupposes the role of imagination (ibid., 40).” He claims that “as imagination is a mode of thought, … it follows that there must be some key relation to language, also, insofar as thought in its fullest sense, is centered on language. The relation between imagination and language is, in fact, a vital one, empirically speaking. It dominates how imagination is exercised (ibid., 43).”
Mark Mattson , author of the article, “Superior pattern processing is the essence of the evolved human brain”, begins his review article in Frontiers in Neuroscience with the following provocative remark in the first two sentences of his abstract:
Humans have long pondered the nature of their mind/brain and, particularly why its capacities for reasoning, communication and abstract thought are far superior to other species, including closely related anthropoids. This article considers superior pattern processing (SPP) as the fundamental basis of most, if not all, unique features of the human brain including intelligence, language, imagination, invention, and the belief in imaginary entities such as ghosts and gods.
What stopped us in our tracks was Mattson’s pairing of “intelligence, language, imagination, invention” with “the belief in imaginary entities such as ghosts and gods”. As practitioners and students of science, we associated “intelligence, language, imagination/abductive reasoning, and invention” with science, engineering and the arts. On the other hand, we associated “belief in imaginary entities such as ghosts and gods” with faith, at best, and superstition, at worst. We were intrigued by Mattson’s abstract and so we read the whole article. As we discussed its thesis, it suddenly occurred to us that perhaps abductive logic or thinking was the link between these two seeming disparate categories of “intelligence, language, imagination and invention”, on the one hand, and the belief in “imaginary entities such as ghosts and gods”, on the other hand.
Abductive logic is unlike deductive logic and inductive logic. Let us explain. With deductive logic, you begin with two axioms that you believe to be self-evident and deduce a conclusion. Socrates is a man. All men are mortal. Therefore, Socrates is mortal. With inductive logic, you list all examples where your conclusion is true and you assume or guess, therefore, it is always true. Socrates was mortal. Aristotle was mortal. Newton was mortal. Einstein was mortal. Therefore, all men are mortal. With abductive reasoning, one observes a set of data and one then guesses or imagines or invents a hypothesis that explains that data, that is the simplest and most likely. All three forms of logic involve guessing in one way or another. With deductive logic, one makes the guess that one’s starting axioms are correct. With inductive logic, one makes the guess that if the statement is true for all the examples that one is able to compile, then it must always be true for all possible cases.
Each of these three forms of logic have different applications:
Mathematics, for the most part, proceeds by way of deductive logic. The axioms that parallel lines (i) remains the same distance apart; (ii) converge; or (iii) diverge, give rise to three forms of geometry, respectively: (i) plane; (ii) Riemannian; and (iii) Lobachevskian.
Inductive reasoning is used for forecasting and cannot guarantee the truth of its conclusion, but only suggest that it is most likely. In most cases, the greater the sample size, the more reliable is the conclusion, but this assertion itself is another example of inductive reasoning.
Abductive thinking, as used in science, only asserts that its conclusions are the simplest and most likely, but must be subjected to constant testing. The criteria for a conclusion to be considered as a scientifically valid conclusion is that it must be falsifiable, as suggested by Karl Popper .
So, what is the connection between “intelligence, language, imagination, invention” and “the belief in imaginary entities such as ghosts and gods”? Belief in imaginary entities, such as ghosts and gods, parallels abductive thinking and requires imagination. Belief in, or even suggesting a hypothesis that explains observed phenomena in science, also involves abductive reasoning and also requires imagination.
Imagination is a key requirement in both science and magical thinking, both of which create or recreate a reality for the one imagining the science hypothesis or the magical thinking. José Monserrat Neto  concurred with this when he suggested “that the capacity of imagination is essential to understand the creative way in which human beings learn and (re)construct their reality.”
A theory or hypothesis in science is an imaginary entity which entails the belief that it might be actual or true. Science and the belief in ghosts or gods is, therefore, parallel to a certain degree. They diverge in that the scientist accepts their hypothesis might be false and hence needs to be constantly tested empirically, whereas the religious or ghost believer does not accept the notion that their belief may be false, but accepts the validity of their belief on faith alone without a need to test their hypothesis.
The human ability to create these hypotheses to account for data involves imagination/abductive reasoning and the ability to combine seemingly disparate patterns and restructure them in new ways. Although a deterministic, machine-like system (artificial intelligence, for instance) is able to use both deductive logic (if-then statements) and inductive logic (machine learning), the use of effective abductive reasoning may be a uniquely human phenomenon. Abductive reasoning is the result of a mathematical mind with the ability to create novel categories or patterns between otherwise seemingly disparate elements via pattern restructuring.
The three different forms of thought or logic, deductive, inductive and abductive, can be seen as ways in which we can navigate information landscapes amongst the different levels of specificity and generality of our concepts that we defined above in the LT uncertainty principle of generalization and specificity (see Figure 1). Deductive logic involves moving from the general to the specific, and, inductive, from the specific to the general. Both of these act as a one-way street of logic. Abductive thought requires a more horizontal, domain-general movement that focuses on forging new connections across ideas and consideration of context, which we believe is uniquely human.
Further supporting the importance of having vivid, detailed, episodic experiences, is that this system may be how we also imagine future events. That is, episodic memory is the foundational, sensational landscape we use to feel like we are there when imagining future events, and also involves the ability to restructure patterns on a whim to create internal worlds.
The same storage of multiple representations via pattern separation and holding multiple representations in mind via working memory, and having access to episodes, are the processes that seem to allow us to imagine future events.
7. Pattern Restructuring: Abductive Reasoning and Creativity
We argued above that abductive reasoning may be able to explain both scientific and superstitious thinking, but where they differ is in terms of falsifiability. Abductive reasoning that leads to such a vast range of what makes us human stretches from science and intelligence, to religious faith and belief in ghosts . Abductive thinking, therefore, seems to be a uniquely human phenomenon. Abductive thinking involves being able to restructure connections between ideas, to create novel ideas to bridge often seemingly distant ideas and to create hypotheses that can explain and unify observations, and to create “just so stories” and coherent narratives. It requires creativity and the ability to connect and restructure patterns
How do we get something seemingly novel from previous information that seems disconnected? Is creativity a magical “and then there was light” phenomenon and, seemingly, something emerging from nothing? Not necessarily. What if we just create new connections between previously existing ideas? This would explain how something seemingly novel can arise from pre-existing, disconnected bits of information. In terms of our “set theory” of mind, creativity comes from this ability to forge novel connections between sets, even sets that may have little overlap at first glance. In other words, the ideas and content remain constant, but it is the connections between these patterns that give way to creativity, imagination and abductive reasoning, which then results in new ideas and new content. The following definition of creative insight is particularly helpful explaining this idea:
(Creative) insight seems to involve (1) an existing state of mind or set of mental structures relevant to the topic and (2) a moment of realization, consequent to new information or a sudden new way of looking at old information, resulting in (3) a quick restructuring of the mental model, which is subjectively perceived as providing a new understanding .
Csikszentmihalyi’s definition of creative thought implies that we have to have these pre-existing sets, formed via our pattern-processing tools, and then creativity/pattern-creation emerges as pattern-restructuring and bridging novel connections between these already existing ideas. This helps explain how novel, creative ideas can come about from seemingly out of nowhere (i.e., the “ah-ha” moment), though not necessarily through any new content, but simply different connections between existing content, which, in turn, creates new content though the new connections. Note that creative thought or abductive reasoning is not finding something from nothing, it is the ability to find something from a group of initially seemingly unrelated things. It is creating new sets of syntactical structures, which, as a result, creates new meaning and hence new knowledge. Everything was there to begin with, we just were able to realize it, or rather, in McLuhan’s words, let go of it to grasp it in a new way, and this process in itself gives rise to new meaning and new information.
Indeed, just as we argued that math and language are ultimately boiled down to pattern restructuring tools, creativity, also, is the ability to restructure information to solve problems or create novel ideas. Again, recall Czkimenthalyi’s first step of creativity, which involves “an existing state of mind or set of mental structures…”, and further supports our view that vivid episodic experiences are required to lend themselves to the increasingly complex pattern restructuring of these ideas, as without this raw resource to return to, we become fixated only on one idea or pattern.
Our ability to imagine and create allows us to create increasingly complex ideas, from technology, art, science, and religion. Ultimately then, many of the qualities that make us human stem as an emergent property of our ability to restructure patterns to zap novel ideas into existence. But of course, all the material is there to begin with, the human mind is just able to recognize, extract, integrate, synthesize, restructure, and realize it into existence.
8. No Signal, Without Noise: The Role of “Randomness” in Pattern-Restructuring
As argued above, creativity involves being able to take seemingly unrelated ideas or sets and restructuring them to make novel ideas. For instance, even at the neuronal network level, the brain seems to have a hard-wired mechanism that works to increase our chances of the finding of novel ideas, by pushing us to restructure our patterns in novel ways. Connections of neurons, which could represent an idea, for instance (i.e., a consistent pattern of neurons fire every time you think of a “dog”), have been found to fire in unpredictable, random connections, called stochastic resonance. While it is still debated, the reason for these “noisy” neurons, it has been recently suggested, can be seen as the brain testing out new connections. This testing out of new neuronal combinations is argued to prevent decisional deadlock, to let us make mistakes to learn from, and might even act as a basis for creativity (see Deco et al. ). This final point on stochastic resonance as the grounds for creativity, is quite the assertion, but follows the idea that certain neuronal computations can be hierarchically abstracted  to assist in explaining increasingly complicated, abstracted ideas.
Randomness and chance indeed play a role in creativity, and our brains may take advantage of this randomness to push towards bridging otherwise disparate ideas. The role of “randomness” and chance is analogous to incredibly creative design we observe in evolution and natural selection. A random mutation that made a giraffe’s neck slightly longer was the necessary random push needed to lead to the impressive design of the giraffe’s famously elongated neck. Similarly, neuronal stochastic resonance, essentially a mutation of neural firing patterns, may be the initial “nudge” needed to lead to a cascade of pattern-restructuring processes, lending itself to the restructuring of ideas, to lead to an impressively novel idea, or creativity. All biological mutations are not necessarily helpful, but we require this variation, and over time and chance, one mutation may prove to be an adaptation. Random neuronal firing may similarly prove to be a creative adaptation, as over time some might push the mind towards finding otherwise unseen connections that turn out to be very useful.
Thus, just as natural selection requires this bit of randomness and open-endedness, the human mind is also remarkably noisy and open-ended. The human brain has more than 100 trillion connections between its neurons. There is a hugely vast number of connections we can forge and reforge to make new ideas. In his new book, Daniel Dennet  wrote that “evolution is all about turning ‘bugs’ into ‘features,’ turning ‘noise’ into ‘signal,’ and the fuzzy boundaries between these categories are not optional; the opportunistic open-endedness of natural selection depends on them.” Analogous to this, we would argue that the flexible human mind also depends on such opportunistic open-endedness and the ability to restructure patterns to allow for creativity and imagination/abductive reasoning.
One person’s noise might be another person’s information. “The user is the content”, as McLuhan once opined  (p. 51). Terrence Deacon  point out that “noise can be signal to a repairman.” As humans are always looking for unseen connections and patterns to better understand our world, we are all repairmen in a sense. As repairmen, we have the appropriate tools to extract signal out of what may have initially appeared as noise. We, as humans, have the cognitive tools necessary to create information.
9. Brand New: Thinking in Patterns
To further support our hypothesis that patterning is a critical part of human cognition, we describe the role of patterning in a number of human intellectual activities, ranging from the fine arts, music and verbal language to mathematics, natural science and the social sciences.
Verbal Language: We have already suggested that the emergence of words as concepts that describe all the percepts associated with that concept is a form of patterning. What applies for semantics also applies to syntax, as grammar also represents a form of patterning. Pragmatics, the third aspect of understanding verbal language, underscores the importance of the pattern of pragmatics in communicating meaning.
Mathematics: Mathematics entails patterns in a multitude of ways. A sequence, for example, is a string of objects, like integers, that follow a particular pattern, such as the set of all even numbers or the set of all integers that are divisible by the integer, n. The Fibonacci sequence is another example of a sequenced pattern. The elements in the sets of all triangles, or of all rectangles, etc., each share a common pattern. Patterns abound in algebra and geometry in numbers too great to describe in this article.
Music: Patterns abound in all forms of music, from the simplest folk song to the most complex symphony, concerto or sonata. A melody is a particular pattern of notes. Rhythmic patterns are an essential form of music. Many musical dance forms have a particular rhythmic pattern, such as the waltz, the mambo, the tango or the samba. The fugue, the sonata form, the rondo form, the round, and counterpoint are examples of the many forms or patterns of music.
The Visual Arts and Architecture: Patterns are an essential part of both the fine and decorative arts, as well as architecture. Symmetry is used throughout the visual arts and architecture and is one of the elements of what we consider to be beautiful, not just in the arts but also what we consider as human beauty. Beginning in the Renaissance, the pattern of perspective, with its vanishing point, is an essential feature of the visual arts.
Engineering: Patterns are an essential part of successful engineering projects, particularly in mechanical and civil engineering.
Science and Social Science: Detecting patterns is an essential part of the natural sciences. The Copernican Revolution, Kepler’s Laws of Planetary Motion, Newton’s Three Laws of Motion and the Law of Gravity, and Maxwell’s Equation of Electromagnetism, all involve identifying patterns in nature. The discovery of the Periodic Table of Elements in chemistry entailed finding the patterns of chemical bonding. The classification of biological species and genera is another example of the uncovering of a pattern in the world of biology. Meteorology is based on the identification of weather patterns. The law of supply and demand is an example of a pattern in economics. Patterns play a role in other social sciences such as sociology, anthropology, law, psychology and cognitive science. Patterning is an essential tool in all of the sciences and the social sciences. In some sense, patterns are a way to understand the order we find in nature and the social interactions of humans.
10. Patterns in Human Culture
We are not crediting all of our creative thought, that is, our ability to form ideas and concepts, to randomness. Perhaps randomness is an offline way in which we can prevent creative deadlock that increases our flexibility. Another way in which we may connect ideas is through pattern-completion in auto-association networks, as suggested by Hebb . Pattern completion occurs when there is high overlap between two experiences, and the brain encodes this information with higher neural similarity in an integrated representation. This may be another mechanism that can help us make new connections.
We are not crediting all of our creative thought to randomness, or our ability to further unravel and form ideas and concepts, but it is perhaps an offline way in which we can prevent creative deadlock and increase our flexibility, within our various ways of restructuring patterns. Similarly, Harnad , in his paper titled “Creativity: Method or Magic”, argued for Pasteur’s Dictum, whereby “chance favours the prepared mind”, for the case of creativity. In our thesis, having access to strong representations of episodic memories and percepts is a way of “preparation” for the creative patterns that can emerge from it.
Although we have focused on the more concrete ways in which we form and manipulate patterns, as seen with the role of randomness, the mind is largely probabilistic and we have enough variation in how we form patterns. As a result, patterns have variation and, thus, become even more powerful, as they can adapt to different contexts.
However, what happens to these patterns as they form? How do they become instantiated in culture? The topology of the mind is structured by the categories that the mind creates. The categories of an individual’s mind are subject to natural selection. Those categorizations that increase the fitness of those that possess them or the culture in which they thrive tend to survive.
While we have focused primarily on the process of pattern restructuring, that is, how the mind forges patterns, now we will also briefly focus on the products of these processes, that is, how properties of the mind itself become instantiated in these patterns over time, rendering them easier to learn.
Each time information is transmitted, whether through neural synapses or verbal speech, it becomes susceptible to change. As a result, the pattern boundaries (the meaningful differences) that come to stick over time are often the easiest to learn, that is, the ones that make it most frequently through the mind’s cognitive filter.
In this story, the mind, as the medium, then becomes the message (McLuhan). Indeed, this system, in which the most “fit” patterns come to stick and with information constantly driving us to seek new ways to restructure, is the dynamic system. This iterative process is the ultimate driving force of patterns, across time and space.
Dawkin’s  meme theory is perhaps the most famous, and controversial, instance of this type of transmission of patterns (or memes), whereby patterns come to best “fit” in the human mind. In Dawkin’s view, memes (or patterns) act as viruses that “infect” the mind. We disagree, as we view pattern-restructuring as the “kind” of pattern-processing that humans excel at. As a result, we place the human mind in a much more active role than Dawkins poses. Indeed, our view falls nicely in line with many critics of Dawkin’s meme theory, because the mind is creating and recreating patterns, it is an active agent that creates novel ideas and not just an “imitator” of ideas . Our central tenant of our thesis is that we do not just recognize patterns, but we internalize them, then we manipulate and restructure them to suit our goals. The mind is not just an imitator or pattern processor, it is an inference creator that actively restructures its internal representations. It is this second aspect that is more characteristically human, that we are able to flexibly restructure our worlds. Our thesis is one that supports the human mind as an active agent, not just a helpless victim of its environment.
Mathematical, linguistic, creative, imaginary, and abductive thinking are the modes by which our mind restructures patterns. We have described how patterns, formed via recognition and restructuring, become instantiated in culture. To conclude, we would suggest patterning, particularly the ability to create or see new unexpected patterns, is the key to creativity in the arts, science and religion, three domains of spirituality that might have more in common than is generally recognized.
