The Dynamic Quality of Henri Bergson

Posted on by

Robert Pirsig writes in Lila that Quality contains a dynamic good in addition to a static good. This dynamic good consists of a search for “betterness” that is unplanned and has no specific destination, but is nevertheless responsible for all progress. Once a dynamic good solidifies into a concept, practice, or tradition in a culture, it becomes a static good. Creativity, mysticism, dreams, and even good guesses or luck are examples of dynamic good in action. Religious traditions, laws, and science textbooks are examples of static goods.

Pirsig describes dynamic quality as the “pre-intellectual cutting edge of reality.” By this, he means that before concepts, logic, laws, and mathematical formulas are discovered, there is process of searching and grasping that has not yet settled into a pattern or solution. For example, invention and discovery is often not an outcome of calculation or logical deduction, but of a “free association of ideas” that tends to occur when one is not mentally concentrating at all. Many creative people, from writers to mathematicians, have noted that they came up with their best ideas while resting, engaging in everyday activities, or dreaming.

Dynamic quality is not just responsible for human creation — it is fundamental to all evolution, from the physical level of atoms and molecules, to the biological level of life forms, to the social level of human civilization, to the intellectual level of human thought. Dynamic quality exists everywhere, but it has no specific goals or plans — it always consists of spur-of-the-moment actions, decisions, and guesses about how to overcome obstacles to “betterness.”

It is difficult to conceive of dynamic quality — by its very nature, it is resistant to conceptualization and definition, because it has no stable form or structure. If it did have a stable form or structure, it would not be dynamic.

However the French philosopher Henri Bergson (1859-1941) provided a way to think about dynamic quality, by positing change as the fundamental nature of reality. (See Beyond the “Mechanism” Metaphor in Physics.) In Bergson’s view, traditional reason, science, and philosophy created static, eternal forms and posited these forms as the foundation of reality — but in fact these forms were tools for understanding reality and not reality itself. Reality always flowed and was impossible to fully capture in any static conceptual form. This flow could best be understood through perception rather than conception. Unfortunately, as philosophy created larger and larger conceptual categories, philosophy tended to become dominated by empty abstractions such as “substance,” “numbers,” and “ideas.” Bergson proposed that only an intuitive approach that enlarged perceptual knowledge through feeling and imagination could advance philosophy out of the dead end of static abstractions.

The Flow of Time

Bergson argued that we miss the flow of time when we use the traditional tools of science, mathematics, and philosophy. Science conceives of time as simply one coordinate in a deterministic space-time block ruled by eternal laws; mathematics conceives of time as consisting of equal segments on a graph; and philosophers since Plato have conceptualized the world as consisting of the passing shadows of eternal forms.

These may be useful conceptualizations, argues Bergson, but they do not truly grasp time. Whether it is an eternal law, a graph, or an eternal form, such depictions are snapshots of reality; they do not and cannot represent the indivisible flow of time that we experience. The laws of science in particular neglected the elements of indeterminism and freedom in the universe. (Henri Bergson once debated Einstein on this topic). The neglect of real change by science was the result of science’s ambition to foresee all things, which motivated scientists to focus on the repeatable and calculable elements of nature, rather than the genuinely new. (The Creative Mind, Mineola, New York: Dover, 2007, p. 3) Those events that could not be predicted were tossed aside as being merely random or unknowable. As for philosophy, Bergson complained that the eternal forms of the philosophers were empty abstractions — the categories of beauty and justice and truth were insufficient to serve as representations of real experience.

Actual reality, according to Bergson, consisted of “unceasing creation, the uninterrupted upsurge of novelty.” (The Creative Mind, p. 7) Time was not merely a coordinate for recording motion in a determinist universe; time was “a vehicle of creation and choice.” (p. 75) The reality of change could not be captured in static concepts, but could only be grasped intuitively. While scientists saw evolution as a combination of mechanism and random change, Bergson saw evolution as a result of a vital impulse (élan vital) that pervaded the universe. Although this vital impetus possessed an original unity, individual life forms used this vital impetus for their own ends, creating conflict between life forms. (Creative Evolution, pp. 50-51)

Biologists attacked Bergson on the grounds that there was no “vital impulse” that they could detect and measure. But biologists argued from the reductionist premise that everything could be explained by reference to smaller parts, and since there was no single detectable force animating life, there was no “vital impetus.” But Bergson’s premise was holistic, referring to the broader action of organic development from lower orders to higher orders, culminating in human beings. There was no separate force — rather entities organized, survived, and reproduced by absorbing and processing energy, in multiple forms. In the words of one eminent biologist, organisms are “resilient patterns . . . in an energy flow.” There is no separate or unique energy of life – just energy.

The Superiority of Perception over Conception

Bergson believed with William James that all knowledge originated in perception and feeling; as human mental powers increased, conceptual categories were created to organize and generalize what we (and others) discovered through our senses. Concepts were necessary to advance human knowledge, of course. But over time, abstract concepts came to dominate human thought to the point at which pure ideas were conceived as the ultimate reality — hence Platonism in philosophy, mathematical Platonism in mathematics, and eternal laws in science. Bergson believed that although we needed concepts, we also needed to rediscover the roots of concepts in perception and feeling:

If the senses and the consciousness had an unlimited scope, if in the double direction of matter and mind the faculty of perceiving was indefinite, one would not need to conceive any more than to reason. Conceiving is a make-shift when perception is not granted to us, and reasoning is done in order to fill up the gaps of perception or to extend its scope. I do not deny the utility of abstract and general ideas, — any more than I question the value of bank-notes. But just as the note is only a promise of gold, so a conception has value only through the eventual perceptions it represents. . . . the most ingeniously assembled conceptions and the most learnedly constructed reasonings collapse like a house of cards the moment the fact — a single fact rarely seen — collides with these conceptions and these reasonings. There is not a single metaphysician, moreover, not one theologian, who is not ready to affirm that a perfect being is one who knows all things intuitively without having to go through reasoning, abstraction and generalisation. (The Creative Mind, pp. 108-9)

In the end, despite their obvious utility, the conceptions of philosophy and science tend “to weaken our concrete vision of the universe.” (p. 111) But we clearly do not have God-like powers to perceive everything, and we are not likely to get such powers. So what do we do? Bergson argues that instead of “trying to rise above our perception of things” through concepts, we “plunge into [perception] for the purpose of deepening it and widening it.” (p. 111) But how exactly are we to do this?

Enlarging Perception

There is one group of people, argues Bergson, that have mastered the ability to deepen and widen perception: artists. From paintings to poetry to novels and musical compositions, artists are able to show us things and events that we do not directly perceive and evoke a mood within us that we can understand even if the particular form that the artist presents may never have been seen or heard by us before. Bergson writes that artists are idealists who are often absent-mindedly detached from “reality.” But it is precisely because artists are detached from everyday living that they are able to see things that ordinary, practical people do not:

[Our] perception . . . isolates that part of reality as a whole that interests us; it shows us less the things themselves than the use we can make of them. It classifies, it labels them beforehand; we scarcely look at the object, it is enough for us to know which category it belongs to. But now and then, by a lucky accident, men arise whose senses or whose consciousness are less adherent to life. Nature has forgotten to attach their faculty of perceiving to their faculty of acting. When they look at a thing, they see it for itself, and not for themselves. They do not perceive simply with a view to action; they perceive in order to perceive — for nothing, for the pleasure of doing so. In regard to a certain aspect of their nature, whether it be their consciousness or one of their senses, they are born detached; and according to whether this detachment is that of a particular sense, or of consciousness, they are painters or sculptors, musicians or poets. It is therefore a much more direct vision of reality that we find in the different arts; and it is because the artist is less intent on utilizing his perception that he perceives a greater number of things. (The Creative Mind, p. 114)

The Method of Intuition

Bergson argued that the indivisible flow of time and the holistic nature of reality required an intuitive approach, that is “the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it.” (The Creative Mind, p. 135) Analysis, as in the scientific disciplines, breaks down objects into elements, but this method of understanding is a translation, an insight that is less direct and holistic than intuition. The intuition comes first, and one can pass from intuition to analysis but not from analysis to intuition.

In his essay on the French philosopher Ravaisson, Bergson underscored the benefits and necessity of an intuitive approach:

[Ravaisson] distinguished two different ways of philosophizing. The first proceeds by analysis; it resolves things into their inert elements; from simplification to simplification it passes to what is most abstract and empty. Furthermore, it matters little whether this work of abstraction is effected by a physicist that we may call a mechanist or by a logician who professes to be an idealist: in either case it is materialism. The other method not only takes into account the elements but their order, their mutual agreement and their common direction. It no longer explains the living by the dead, but, seeing life everywhere, it defines the most elementary forms by their aspiration toward a higher form of life. It no longer brings the higher down to the lower, but on the contrary, the lower to the higher. It is, in the real sense of the word, spiritualism. (p. 202)

From Philosophy to Religion

A religious tendency is apparent in Bergson’s philosophical writings, and this tendency grew more pronounced as Bergson grew older. It is likely that Bergson saw religion as a form of perceptual knowledge of the Good, widened by imagination. Bergson’s final major work, The Two Sources of Morality and Religion (Notre Dame, IN: University of Notre Dame Press, 1977) was both a philosophical critique of religion and a religious critique of philosophy, while acknowledging the contributions of both forms of knowledge. Bergson drew a distinction between “static religion,” which he believed originated in social obligations to society, and “dynamic religion,” which he argued originated in mysticism and put humans “in the stream of the creative impetus.” (The Two Sources of Morality and Religion, p. 179)

Bergson was a harsh critic of the superstitions of “static religion,” which he called a “farrago of error and folly.” These superstitions were common in all cultures, and originated in human imagination, which created myths to explain natural events and human history. However, Bergson noted, static religion did play a role in unifying primitive societies and creating a common culture within which individuals would subordinate their interests to the common good of society. Static religion created and enforced social obligations, without which societies could not endure. Religion also provided comfort against the depressing reality of death. (The Two Source of Morality and Religion, pp. 102-22)

In addition, it would be a mistake, Bergson argued, to suppose that one could obtain dynamic religion without the foundation of static religion. Even the superstitions of static religion originated in the human perception of a beneficent virtue that became elaborated into myths. Perhaps thinking that a cool running spring or a warm fire on the hearth as the actions of spirits or gods were a case of imagination run rampant, but these were still real goods, as were the other goods provided by the pagan gods.

Dynamic religion originated in static religion, but also moved above and beyond it, with a small number of exceptional human beings who were able to reach the divine source: “In our eyes, the ultimate end of mysticism is the establishment of a contact . . . with the creative effort which life itself manifests. This effort is of God, if it is not God himself. The great mystic is to be conceived as an individual being, capable of transcending the limitations imposed on the species by its material nature, thus continuing and extending the divine action.” (pp. 220-21)

In Bergson’s view, mysticism is intuition turned inward, to the “roots of our being , and thus to the very principle of life in general.” (p. 250) Rational philosophy cannot fully capture the nature of mysticism, because the insights of mysticism cannot be captured in words or symbols, except perhaps in the word “love”:

God is love, and the object of love: herein lies the whole contribution of mysticism. About this twofold love the mystic will never have done talking. His description is interminable, because what he wants to describe is ineffable. But what he does state clearly is that divine love is not a thing of God: it is God Himself. (p. 252)

Even so, just as the dynamic religion bases its advanced moral insights in part on the social obligations of static religion, dynamic religion also must be propagated through the images and symbols supplied by the myths of static religion. (One can see this interplay of static and dynamic religion in Jesus and Gandhi, both of whom were rooted in their traditional religions, but offered original teachings and insights that went beyond their traditions.)

Toward the end of his life, Henri Bergson strongly considered converting to Catholicism (although the Church had already placed three of Bergson’s works on its Index of Prohibited Books). Bergson saw Catholicism as best representing his philosophical inclinations for knowing through perception and intuition, and for joining the vital impetus responsible for creation. However, Bergson was Jewish, and the anti-Semitism of 1930s and 1940s Europe made him reluctant to officially break with the Jewish people. When the Nazis conquered France in 1940 and the Vichy puppet government of France decided to persecute Jews, Bergson registered with the authorities as a Jew and accepted the persecutions of the Vichy regime with stoicism. Bergson died in 1941 at the age of 81.

Once among the most celebrated intellectuals in the world, today Bergson is largely forgotten. Even among French philosophers, Bergson is much less known than Descartes, Sartre, Comte, and Foucault. It is widely believed that Bergson lost his debate with Einstein in 1922 on the nature of time. (See Jimena Canales, The Physicist and the Philosopher: Einstein, Bergson, and the Debate that Changed Our Understanding of Time, p. 6) But it is recognized today even among physicists that while Einstein’s conception of spacetime in relativity theory is an excellent theory for predicting the motion of objects, it does not disprove the existence of time and real change. It is also true that Bergson’s writings are extraordinarily difficult to understand at times. One can go through pages of dense, complex text trying to understand what Bergson is saying, get suddenly hit with a colorful metaphor that seems to explain everything — and then have a dozen more questions about the meaning of the metaphor. Nevertheless, Bergson remains one of the very few philosophers who looked beyond eternal forms to the reality of a dynamic universe, a universe moved by a vital impetus always creating, always changing, never resting.

Knowledge without Reason

Posted on by

Is it possible to gain real and valuable knowledge without using reason? Many would scoff at this notion. If an idea can’t be defended on rational grounds, it is either a personal preference that may not be held by others or it is false and irrational. Even if one acknowledges a role for intuition in human knowledge, how can one trust another person’s intuition if that person does not provide reasons for his or her beliefs?

In order to address this issue, let’s first define “reason.” The Encyclopedia Britannica defines reason as “the faculty or process of drawing logical inferences,” that is, the act of developing conclusions through logic. Britannica adds, “Reason is in opposition to sensation, perception, feeling, desire, as the faculty . . .  by which fundamental truths are intuitively apprehended.” The New World Encyclopedia defines reason as “the ability to form and operate upon concepts in abstraction, in accordance with rationality and logic. ” Wikipedia states: “Reason is the capacity of consciously making sense of things, applying logic, and adapting or justifying practices, institutions, and beliefs based on new or existing information.”

Fundamental to all these definitions is the idea that knowledge must be based on explicit concepts and statements, in the form of words, symbols, or mathematics. Since human language is often ambiguous, with different definitions for the same word (I could not even find a single, widely-accepted definition of “reason” in standard reference texts), many intellectuals have believed that mathematics, science, and symbolic logic are the primary means of acquiring the most certain knowledge.

However, there are types of knowledge not based on reason. These types of knowledge are difficult or impossible to express in explicit concepts and statements, but we know that they are types of knowledge because they lead to successful outcomes. In these cases, we don’t know how exactly a successful outcome was reached — that remains a black box. But we can judge that the knowledge is worthwhile by the actor’s success in achieving that outcome. There are at least six types of non-rational knowledge:

 

1. Perceptual knowledge

In a series of essays in the early twentieth century, the American philosopher William James drew a distinction between “percepts” and “concepts.” According to James, originally all human beings, like the lower life forms, gathered information from their environment in the form of perceptions and sensations (“percepts”). It was only later in human evolution that human beings created language and mathematics, which allowed them to form concepts. These concepts categorized and organized the findings from percepts, allowing communication between different humans about their perceptual experiences and facilitating the growth of reason. In James’s words, “Feeling must have been originally self-sufficing; and thought appears as a super-added function, adapting us to a wider environment than that of which brutes take account.” (William James, “Percept and Concept – The Import of Concepts“).

All living creatures have perceptual knowledge. They use their senses and brains, however primitive, to find shelter, find and consume food, evade or fight predators, and find a suitable mate. This perceptual knowledge is partly biologically ingrained and partly learned (habitual), but it is not the conceptual knowledge that reason uses. As James noted, “Conception is a secondary process, not indispensable to life.” (Percept and Concept – The Abuse of Concepts)

Over the centuries, concepts became predominant in human thinking, but James argued that both percepts and concepts were needed to fully know reality. What concepts offered humans in the form of breadth, argued James, it lost in depth. It is one thing to know the categorical concepts “desire,” “fear,” “joy,” and “suffering,” ; it is quite another to actually experience desire, fear, joy, and suffering. Even relatively objective categories such as “water,” “stars,” “trees,” “fire,” and so forth are nearly impossible to adequately describe to someone who has not seen or felt these phenomena. Concepts had to be related to particular percepts in the real world, concluded James, or they were merely empty abstractions.

In fact, most of the other non-rational types of knowledge I am about to describe below appear to be types of perceptual knowledge, insofar as they involve perceptions and sensations in making judgments. But I have broken them out into separate categories for purposes of clarity and explanation.

 

2. Emotional knowledge

In a previous post, I discussed the reality of emotional knowledge by pointing to the studies of Professor of Neuroscience Antonio Damasio (see Descartes’ Error: Emotion, Reason, and the Human Brain). Damasio studied a number of human subjects who had lost the part of their brain responsible for emotions, whether due to an accident or a brain tumor. According to Damasio, these subjects experienced a marked decline in their competence and decision-making capability after losing their emotional capacity, even though their IQs remained above-normal. They did not lose their intellectual ability, but their emotions. And that made all the difference. They lost their ability to make good decisions, to effectively manage their time, and to navigate relationships with other human beings. Their competence diminished and their productivity at work plummeted.

Why was this? According to Damasio, when these subjects lost their emotional capacity, they also lost their ability to value. And when they lost their ability to value, they lost their capacity to assign different values to the options they faced every day, leading to either a paralysis in decision-making or to repeatedly misplaced priorities, focusing on trivial tasks rather than important tasks.

Now it’s true that merely having emotions does not guarantee good decisions. We all know of people who make poor decisions because they have anger management problems, they suffer from depression, or they seem to be addicted to risk-taking. The trick is to have the right balance or disposition of emotions. Consequently, a number of scientists have attempted to formulate “EQ” tests to measure persons’ emotional intelligence.

 

3. Common life / culture

People like to imagine that they think for themselves, and this is indeed possible — but only to a limited extent. We are all embedded in a culture, and this culture consists of knowledge and practices that stretch back hundreds or thousands of years. The average English-language speaker has a vocabulary of tens of thousands of words. So how many of those words has a typical person invented? In most cases, none – every word we use is borrowed from our cultural heritage. Likewise, every concept we employ, every number we add or subtract, every tradition we follow, every moral rule we obey is transmitted to us down through the generations. If we invent a new word that becomes widely adopted, if we come up with an idea that is both completely original and worthy, that is a very rare event indeed.

You may argue, “This may well be true. But you know perfectly well that cultures, or the ‘common life’ of peoples are also filled with superstition, with backwardness, and barbarism. Moreover, these cultures can and do change over time. The use of reason, from the most intelligent people in that culture, has overcome many backward and barbarous practices, and has replaced superstition with science.” To which, I reply, “Yes, but very few people actually have original and valuable contributions to knowledge, and their contributions are often few and in specialized fields. Even these creative geniuses must take for granted most of the culture they have lived in. No one has the time or intelligence to create a plan for an entirely new society. The common life or culture of a society is a source of wisdom that cannot be done away with entirely.”

This is essentially the insight of the eighteenth century philosopher David Hume. According to Hume, philosophers are tempted to critique all the common knowledge of society as being unfounded in reason and to begin afresh with pure deductive logic, as did Descartes.  But this can only end in total skepticism and nihilism. Rather, argues Hume, “true philosophy” must work within the common life. As Donald W. Livingstone, a former professor at Emory University, has explained:

Hume defines ‘true philosophy’ as ‘reflections on common life methodized and corrected.’ . . . The error of philosophy, as traditionally conceived—and especially modern philosophy—is to think that abstract rules or ideals gained from reflection are by themselves sufficient to guide conduct and belief. This is not to say abstract rules and ideals are not needed in critical thinking—they are—but only that they cannot stand on their own. They are abstractions or stylizations from common life; and, as abstractions, are indeterminate unless interpreted by the background prejudices of custom and tradition. Hume follows Cicero in saying that ‘custom is the great guide of life.’ But custom understood as ‘methodized and corrected’ by loyal and skillful participants. (“The First Conservative,” The American Conservative, August 10, 2011)

 

4. Tacit knowledge / Intuition

Is it possible to write a perfect manual on how to ride a bicycle, one that successfully instructs a child on how to get on a bicycle for the first time and ride it perfectly? What about a perfect cookbook, one that turns a beginner into a master chef upon reading it? Or what about reading all the books in the world about art — will that give someone what they need to create great works of art? The answer to all of these questions is of course, “no.” One must have actual experience in these activities. Knowing how to do something is definitely a form of knowledge — but it is a form of knowledge that is difficult or impossible to transmit fully through a set of abstract rules and instructions. The knowledge is intuitive and habitual. Your brain and central nervous system make minor adjustments in response to feedback every time you practice an activity, until you master it as well as you can. When you ride a bike, you’re not consciously implementing a set of explicit rules inside your head, you’re carrying out an implicit set of habits learned in childhood. Obviously, talents vary, and practice can only take us so far. Some people have a natural disposition to be great athletes or artists or chefs. They can practice the same amount as other people and yet leap ahead of the rest.

The British philosopher Gilbert Ryle famously drew a distinction between two forms of knowledge: “knowing how” and “knowing that.” “Knowing how” is a form of tacit knowledge and precedes “knowing that,” i.e., knowing an explicit set of abstract propositions. Although we can’t fully express tacit knowledge in language, symbolic logic, or mathematics, we know it exists, because people can and will do better at certain activities by learning and practicing. But they are not simply absorbing abstract propositions — they are immersing themselves in a community, they are working alongside a mentor, and they are practicing with the guidance of the community and mentor. And this method of learning how also applies to learning how to reason in logic and mathematics. Ryle has pointed out that it is possible to teach a student everything there is to know about logical proofs — and that student may be able to fully understand others’ logical proofs. And yet when it comes to doing his or her own logical proofs, that student may completely fail. The student knows that but does not know how.

A recent article on the use of artificial intelligence in interpreting medical scans points out that it is virtually impossible for humans to be fully successful in interpreting medical scans simply by applying a set of rules. The people who were best at diagnosing medical scans were not applying rules but engaging in pattern recognition, an activity that requires talent and experience but can’t be fully learned in a text. Many times when expert diagnosticians are asked how they came to a certain conclusion, they have difficulty describing their method in words — they may say a certain scan simply “looks funny.” One study described in the article concluded that pattern recognition uses a part of the brain responsible for naming things:

‘[A] process similar to naming things in everyday life occurs when a physician promptly recognizes a characteristic and previously known lesion,’ the researchers concluded. Identifying a lesion was a process similar to naming the animal. When you recognize a rhinoceros, you’re not considering and eliminating alternative candidates. Nor are you mentally fusing a unicorn, an armadillo, and a small elephant. You recognize a rhinoceros in its totality—as a pattern. The same was true for radiologists. They weren’t cogitating, recollecting, differentiating; they were seeing a commonplace object.

Oddly enough, it appears to be possible to teach computers implicit knowledge of medical scans. A computing strategy known as a “neural network” attempts to mimic the human brain by processing thousands or millions of patterns that are fed into the computer. If the computer’s answer is correct, the connection responsible for that answer is strengthened; if the answer is incorrect, that connection is weakened. Over time, the computer’s ability to arrive at the correct answer increases. But there is no set of rules, simply a correlation built up over thousands and thousands of scans. The computer remains a “black box” in its decisions.

 

5. Creative knowledge

It is one thing to absorb knowledge — it is quite another to create new knowledge. One may attend school for 15 or 20 years and diligently apply the knowledge learned throughout his or her career, and yet never invent anything new, never achieve any significant new insight. And yet all knowledge was created by various persons at one point in the past. How is this done?

As with emotional knowledge, creative knowledge is not necessarily an outcome of high intelligence. While creative people generally have an above-average IQ, the majority of creative people do not have a genius-level IQ (upper one percent of the population). In fact, most geniuses do not make significant creative contributions. The reason for this is that new inventions and discoveries are rarely an outcome of logical deduction but of a “free association” of ideas that often occurs when one is not mentally concentrating at all. Of note, creative people themselves cannot precisely describe how they get their ideas. The playwright Neil Simon once said, “I don’t write consciously . . . I slip into a state that is apart from reality.” According to one researcher, “[C]reative people are better at recognizing relationships, making associations and connections, and seeing things in an original way — seeing things that others cannot see.” Moreover, this “free association” of ideas actually occurs most effectively while a person is at rest mentally: drifting off to sleep, taking a bath or shower, or watching television.

Mathematics is probably the most precise and rigorous of disciplines, but mathematical discovery is so mysterious that mathematicians themselves have compared their insights to mysticism. The great French mathematician Henri Poincare believed that the human mind worked subliminally on problems, and his work habit was to spend no more than two hours at a time working on mathematics. Poincare believed that his subconscious would continue working on problems while he conducted other activities, and indeed, many of his great discoveries occurred precisely when he was away from his desk. John von Neumann, one of the best mathematicians of the twentieth century, also believed in the subliminal mind. He would sometimes go to sleep with a mathematical problem on his mind and wake up in the middle of the night with a solution. Reason may be used to confirm or disconfirm mathematical discoveries, but it is not the source of the discoveries.

 

6. The Moral Imagination

Where do moral rules come from? Are they handed down by God and communicated through the sacred texts — the Torah, the Bible, the Koran, etc.? Or can morals be deduced by using pure reason, or by observing nature and drawing objective conclusions, they same way that scientists come to objective conclusions about physics and chemistry and biology?

Centuries ago, a number of philosophers rejected religious dogma but came to the conclusion that it is a fallacy to suppose that reason is capable of creating and defending moral rules. These philosophers, known as the “sentimentalists,” insisted that human emotions were the root of all morals. David Hume argued that reason in itself had little power to motivate us to help others; rather sympathy for others was the root of morality. Adam Smith argued that the basis of sympathy was the moral imagination:

As we have no immediate experience of what other men feel, we can form no idea of the manner in which they are affected, but by conceiving what we ourselves should feel in the like situation. Though our brother is upon the rack, as long as we ourselves are at our ease, our senses will never inform us of what he suffers. They never did, and never can, carry us beyond our own person, and it is by the imagination only that we can form any conception of what are his sensations. . . . It is the impressions of our own senses only, not those of his, which our imaginations copy. By the imagination we place ourselves in his situation, we conceive ourselves enduring all the same torments, we enter as it were into his body, and become in some measure the same person with him, and thence form some idea of his sensations, and even feel something which, though weaker in degree, is not altogether unlike them. His agonies, when they are thus brought home to ourselves, when we have thus adopted and made them our own, begin at last to affect us, and we then tremble and shudder at the thought of what he feels. (The Theory of Moral Sentiments, Section I, Chapter I)

Adam Smith recognized that it was not enough to sympathize with others; those who behaved unjustly, immorally, or criminally did not always deserve sympathy. One had to make judgments about who deserved sympathy. So human beings imagined “a judge between ourselves and those we live with,” an “impartial and well-informed spectator” by which one could make moral judgments. These two imaginations — of sympathy and of an impartial judge — are the real roots of morality for Smith.

This brings us to our final topic: the role of non-rational forms of knowledge within reason itself.

Aristotle is regarded as the founding father of logic in the West, and his writings on the subject are still influential today. Aristotle demonstrated a variety of ways to deduce correct conclusions from certain premises. Here is one example that is not from Aristotle, but which has been used as an example of Aristotle’s logic:

All men are mortal. (premise)

Socrates is a man. (premise)

Therefore, Socrates is mortal. (conclusion)

The logic is sound, and the conclusion follows from the premises. But this simple example was not at all typical of most real-life puzzles that human beings faced. And there was an additional problem.

If one believed that all knowledge had to be demonstrated through logical deduction, that rule had to be applied to the premises of the argument as well. Because if the premises were wrong, the whole argument was wrong. And every argument had to begin with at least one premise. Now one could construct another argument proving the premise(s) of the first argument — but then the premises of the new argument also had to be demonstrated, and so forth, in an infinite regress.

To get out of this infinite regress, some argued that deduced conclusions could support premises in the same way as the premises supported a conclusion, a type of circular support. But Aristotle rejected this argument as incoherent. Instead, Aristotle offered an argument that to this day is regarded as difficult to interpret.

According to Aristotle, there is another cognitive state, known as “nous.” It is difficult to find an English equivalent of this word, and the Greeks themselves seemed to use different meanings, but the word “nous” has been translated as “insight,” “intuition,” or “intelligence.” According to Aristotle, nous makes it possible to know certain things immediately without going through a process of argument or logical deduction. Aristotle compares this power to perception, noting that we have the power to discern different colors with our eyesight even without being taught what colors are. It is an ingrained type of knowledge that does not need to be taught. In other words, nous is a type of non-rational knowledge — tacit, intuitive, and direct, not requiring concepts!
