The text proposes replacing traditional theories of causality with the concept of "reactibility," enabling a unified interpretation of inorganic entities, organisms, and cultural beings. Higher levels of reactibility lead to a greater degree of indeterminacy, which serves as a necessary precondition for freedom. However, freedom is not mere randomness; it primarily consists of the subject's sensitivity to non-objective situational challenges and possibilities. The author emphasizes the indispensable role of the subject, who reacts to their temporal environment and distinguishes between abstract notions of past and future and their own subjective "been-ness" and "coming-ness." Consequently, a subject's reaction is not limited to external stimuli but includes responses to what is emerging or what is yet to happen. This approach allows for viewing a subject's actions as an active process of actualizing possibilities, where the key role is played by the subject's ability to relate to their own future and respond to challenges that are not directly given by material reality.
