就人类而言，各种日常行为的目标与这两条生物学定律之间的联系并不那么直接，然而这些规律仍然激励影响着我们。人类能够将自己投射到未来，思考抽象和意识，因此他们的目标可能具有“超越transcendence”（哲学）和“象征symbol”的特征，比如人们通常表现出对上帝或来世的信仰。<ref name="kepinski1974"/><ref name="kepinski1972b"/>

===The hierarchy of value===
It is impossible to keep track of all information generated by various processes occurring in reality. As organisms strive to fulfill two biological laws, proper selection of signals becomes a central problem.<ref name="kepinski1974"/> According to Kępiński, a hierarchy of value is necessary in order to integrate information. In humans, that hierarchy comprises three levels i.e. biological, emotional and sociocultural.<ref name="schochow2016">

It is impossible to keep track of all information generated by various processes occurring in reality. As organisms strive to fulfill two biological laws, proper selection of signals becomes a central problem.[7] According to Kępiński, a hierarchy of value is necessary in order to integrate information. In humans, that hierarchy comprises three levels i.e. biological, emotional and sociocultural.[10] The first two levels are handled subconsciously. The third level, by contrast, is associated with consciousness. From the biological perspective, the number of processes occurring simultaneously in the organism and its physical surroundings is virtually infinite. There is also infinite number of ways in which these processes may be framed. That complexity must be reduced, as only selected signals may be sensed and processed in the nervous system. Moreover, the signals must be ordered according to their present and future relevance. The structure of the body and locations of various receptors are evolutionally adapted to assure isolation of the most relevant signals from the surrounding environment. The internal structure of the body is adjusted to ensure proper integration of information. Of all signals collected by the receptors, only the most important ones reach the level of subjective experience. At the level of signals reaching the field of subjective experience, attention is actively directed (with the help of emotions) towards those related with two biological laws. Perception is not passive and inclusive, but anticipatory and selective.[7] Above biological and emotional levels of signal interpretation, there is the frame of social and cultural norms of the community, which serves as reference for conscious decisions. The sociocultural background plays significant role in people's lives.[8]
===Two phases of information metabolism===
The division of information metabolism into two phases is loosely based on the analysis of the [[orienting response]]. Information metabolism is initiated by the perception of a change in the internal or external environment of the organism. In the first phase, the organism seeks to obtain direct information about the perceived [[phenomenon]]. Because of that, it must turn its attention 'outside' to the reality. The perceived phenomenon is then [[Unconscious mind|subconsciously]] evaluated. The result of that evaluation manifests itself as an [[emotion]]. The sign of the invoked emotion may be positive or negative. This emotion, arising quickly and automatically, serves as the background for the second phase of information metabolism.<ref name="kepinski1974"/>
In the second phase, the organism executes a locomotor reaction to the phenomenon. Motion towards the source of the stimulus is performed if the [[stimulus (physiology)|stimulus]] signifies a positive possibility. If the stimulus was evaluated negatively in the first phase, then it is likely that the executed reaction will take the form of escape, fight or immobilization. During the second phase, the organism is primarily occupied by its own actions. It observes their effect and makes adjustments (which forms a [[feedback]] loop). Despite the feedback, its connection with reality is less intensive than during the first phase. The separation from reality in the second phase of information metabolism is greater in complex animals and reaches its maximum in humans.<ref name="kepinski1974"/>

Functional structures
The term functional structure was used by Kępiński to denote two phenomena. Firstly, the term was used to denote the reaction of an organism to a stimulus. Secondly, it denoted the model of reality generated in the mind in the second phase of the information metabolism.[7] In the case of humans, the number of possible functional structures associated with the first phase of information metabolism is limited. These include, for example, endocrine reactions of the autonomous nervous system and basic locomotor patterns.
The range and complexity of functional structures generated in the second phase is much broader. Humans possess the ability to generate many possible models of reality in response to a newly perceived phenomenon. Functional structures can be relatively complex. They include predictions regarding the behavior of objects in the environment as well as the planned sequence of actions of the individual. Typically, multiple functional structures are generated in the second phase of information metabolism, but only one is embodied (executed). The ones that were generated but rejected, gradually fall into the unconscious and form the Jungian shadow. If particular structure is embodied, the probability of its selection in the future increases. Forgotten structures may manifest themselves in the least expected moment. That situation is known as the possession by the Shadow. Kępiński mentioned that the embodied reaction is a signal to other organisms. It always takes the form of motion (or lack of it).[7] In case of humans, it may be speech (according to Kępiński, speech is the highest form of motion [7][5]).
Emotional coloration
Emotional coloration manifests in the first phase of information metabolism.[7] It signifies the general attitude of the organism towards the stimulus. This attitude may be either positive or negative. It depends on the nature of the stimulus and on the physical condition of the organism in the moment of perception. The individual has very little conscious control over the feeling that arises. It is selected at lower levels of neurophysiological operation. Selection of an attitude in the first phase (positive or negative) limits the character of functional structures generated in the second phase. Although typically there are many possible ways of reacting, they are limited by the emotional background appearing in the first phase.
The reality is not static but it always evolves, even though some regularities and laws may be identified. Due to that, the effort associated with organizing the world adequately to our own needs continues through the whole life. It cannot be ceased because of the second law of thermodynamics.[7] In order to decrease its own entropy and the entropy of its immediate surroundings, the organism must expend energy. This is subjectively experienced as the feeling of difficulty, effort or burden. Integrative effort is inherent to life. This effort is rewarded by positive emotional state – the feeling of satisfaction associated with the overcoming of obstacles and advancing towards important goals. By contrast, negative feelings, such as anxiety or fear, signify danger. In case of anxiety, this danger is typically distant in time and space and not known precisely. Fear, on the contrary, signifies close and specified threat to the integrity of the organism.[8]
In healthy individuals, the balance between negative and positive emotions is on the side of the positive. They are more willing to engage in the exchange of information with the environment and to undertake tasks associated with the integrative effort. By contrast, depressive patients withdraw from reality, which lowers their rate of information metabolism. In many cases, the predisposition to depression is caused by the lack of warm and friendly maternal environment during childhood.[7] The presence of friendly and safe maternal environment during childhood is crucial for the development of the general positive attitude towards the environment. If the childhood environment is hostile, the attitude of withdrawal is reinforced and becomes automated.[7]
The problem of authority
Life may be seen as conflict between two orders – the order of the individual and the order of the environment. As a process placed between these two orders, information metabolism becomes the tool for establishing the right balance of authority ("I am in control" versus "I am controlled").[7] In pathological cases, the individual may aim to gain absolute control over their environment, or quite contrarily, to fully submit to some external power (i.e. their partner, a political group etc.). The need for an absolute control cannot be fulfilled, therefore it frequently takes the form of fantasy, which sometimes becomes indistinguishable from reality (e.g. in schizophrenia).[5] Many individuals submit to revolutionary movements, promising a utopian future, and to social ideologies which offer simple answers to complex life problems. They give up their individual responsibility to find relief from the burdens of life. In his reflections on information metabolism, Kępiński tried to explain psychological mechanisms which made the atrocities of the Second World War possible.[5][9]
The anatomical basis of information metabolism
It is traditionally assumed that functional structures associated with the subjective experience of emotions and moods (the first phase of information metabolism) are controlled by phylogenetically older parts of the brain (diencephalon and rhinencephalon), while those generated in the second phase of information metabolism, subjectively experienced as thoughts, are associated with the neocortex.[7]
The mathematical character of information metabolism
The mathematical character of information metabolism is twofold. Receptors, acting as inputs for the metabolized signals, operate analogically to analog electronic devices. The processing of signals in the remaining part of the nervous system is binary (the response of a neuron may be twofold: null – no response, or 1 – when the action potential is released). Due to these characteristics, organisms may be considered analogous to digital systems.[4][7]
