Reality is given to man through his actions. Uncertainty is the degree of adaptation (or, what is actually the same thing, inadaptation) of human needs and actions to reality. It is the discrepancy between reality and human needs. Complete adaptation would mean that the satisfaction of needs does not require human actions, in which case there would be no uncertainty at all. In practice, however, there are hardly any situations of complete certainty, so that man must act. Frank Knight argued that human wants are those needs that cause goal-directed action.
“We ‘need’ iodides and vitamins, and an infinite number of things of whose existence the race at large has been blissfully ignorant; but we do not ‘want’ them, because they give rise to no conflicts and hence no ‘conduct.’ The common basis of conflict, and we may say of the existence of wants at all, is the limitation in the means of gratifying some impulse or need” (Knight 1964, p. 60).
In school economics, uncertainty comes down to limited resources, to a lack of resources compared to human needs. But resource scarcity is just a special case of uncertainty. Another case is, for example, asymmetric knowledge, when one person knows something that another person does not know and uses this to deceive. Both are just special cases of uncertainty, that is, randomness, surprise, unpredictability.
Meaning as determinateness aims to adapt people and reality to each other, to overcome uncertainty. This gives meanings a great deal of inertia: people prefer to adapt and interpret meanings rather than abandon them. Talcott Parsons wrote that interpretation is the reason why sudden changes in the environment do not lead to the abandonment of the “symbolic formulae” and “elements of cultural tradition” on which social systems are based. Parsons (1964, p. 296) called this mechanism “adaptation by interpretation.” This mechanism has a long history that probably goes beyond humans: practices are derived from traditions and values of animals, simple causal models are older than intelligence itself:
“… Morality derives from values, rather than reason. Jonathan Haidt has found evidence for just this dominance. People try to justify their values by citing reasons for them, but if our reasons are demolished we conjure up others, rather than revise our values. Our reasons are revealed as a self-deceiving charade, a sham called ‘motivated reasoning.’ Reasons are anchored on values, not values on reasons” (Collier 2018, p. 35).
The inertia of meanings leads to the formation of stable meanings—norms—and to the creation of a socio-cultural order consisting of these norms. Meanings in their normative mode are those traditions and “social contracts” that enable society to function as a single whole. Order is constantly undermined by changes in the environment. In the early stages of cultural evolution, when the environment was still largely reduced to nature, order responded mainly to events and phenomena in the natural habitat. Adaptation to the environment occurs faster than the adaptation of the environment to human needs (Livi Bacci 2000, p. 4). Appropriation and consumption precede production. However, as the cultural niche expanded and developed into a cultural environment, order too had to change under the influence of cultural events and phenomena. Over time, cultural events have occurred more frequently and became increasingly unpredictable.
“Economists, typically, do not ask themselves about the structure that humans impose on themselves to order their environment, and therefore reduce uncertainty; nor are they typically concerned with the dynamic nature of the world in which we live, which continues to produce novel problems to be solved. The last point raises a fundamental issue. If we are continually creating a new and novel world, how good is the theory we have developed from past experience to deal with this novel world?” (North 2005, p. 13).
Events and phenomena are a source of uncertainty. From the perspective of order, an event is news if it represents a deviation from the norm: “An occurrence, a meaningful departure from the norm, (that is, ‘news,’ since the fulfillment of a norm is not ‘news’) depends on one’s concept of the norm” (Lotman 1977, p. 234). The socio-cultural order aims to eliminate uncertainty of events by transforming them into facts (patterns of events) and norms (programs of action). Historically, the more meaningful the appropriation process became, the more meaning humans discovered in nature. But while the uncertainty of nature slowly decreased, cultural uncertainty just as slowly increased.
Knowledge or causal models of events and phenomena are not the exclusive prerogative of humans. The presence of elementary reason (i.e. understanding) in animals is demonstrated by their capacity to comprehend the simplest empirical laws of the environment, which enables them to develop programs of action for new situations. This is the difference between reason or intellect and any form of practice based on repetition or learning (Krushinsky 1986, p. 27). Animals have a mental representation of causality and the foundations of goal-directed behavior:
“When Pavlov began studying the behavior of great apes in his laboratory in the last years of his life, he was already talking quite definitely about a special type of association that can be considered concrete thinking: ‘And when an ape builds his tower to get a fruit, then you cannot call it a ‘conditioned reflex.’ This is a case of knowledge formation, of capturing the normal connection of things. This is a different case. Here it must be said that this is the beginning of knowledge, of understanding a constant connection between things—what underlies all scientific activity, the laws of causality’” (Krushinsky 1986, p. 10).
Human causal models are universal and allow the construction of action programs that are applicable to all situations encountered by a culture-society. In this respect, humans differ from animals, which construct empirical models that are only valid for a specific situation and create probabilistic rather than deterministic action programs (Krushinsky 1986, p. 11).
Knowledge is usually defined as “justified true belief.” However, knowledge cannot be reduced to belief without action. Belief is only justified if it enables action.
“Man is in a position to act because he has the ability to discover causal relations which determine change and becoming in the universe. Acting requires and presupposes the category of causality. Only a man who sees the world in the light of causality is fitted to act. In this sense we may say that causality is a category of action. The category means and ends presupposes the category cause and effect” (Mises 1996, p. 22).
As a cause-effect model or pattern of events, knowledge also implies a set of skills, that is, an action program.
Populations under mixed selection
The evolution of proto-humanity was based on the self-reproduction of its populations. The ability to reproduce is a property of life, but a cell or an organism can only reproduce as a whole: selection cannot act within them. A population as a collection of organisms of one species in a relatively closed habitat is the actual sphere of action of natural selection: the self-reproduction of a population is not based on the reproduction of the whole, but on self-renewal, on the alternation of generations of individuals (Berg 1993, p. 251).
Early human populations remained at the mercy of natural selection, but with the accumulation of culture, the self-reproduction of populations changed its character: populations became cultures-societies that reproduced themselves not only through natural but also through cultural mechanisms—not only through the transmission of genes and the interaction of organisms with the habitat, but also through the transmission of meanings and interaction of humans with the domus. Natural selection was gradually supplemented and expanded by cultural selection. Modern man is the result of a mixture of natural and cultural selection, he represents the unity of genotype and meaning type.
During the millions of years of mixed selection, the evolution of practices went hand in hand with the evolution of organisms, ensuring the adaptation of proto-human populations to a changing natural and cultural milieu—to changes in climate and natural landscape, as well as to changes in the landscape of meanings. Mixed selection has left clear traces in the human body.
