This text examines the evolution of the concept of causality from antiquity to the modern era. The author argues that contemporary understanding is a simplified remnant of the original Greek concept. While Aristotle defined four types of causes, modern science and philosophy have largely rejected the material, formal, and final causes, reducing causality to the efficient cause (causa efficiens). The essay highlights David Hume’s fundamental critique, which demonstrated that causal links are not rationally transparent but are based on experience and habit. To address these conceptual shortcomings, the author proposes a shift inspired by the Czech word "příčina" (related to "doing" or "adding"). He suggests that activity should not be attributed to the cause itself, but rather to the reacting subject. It is the subject’s reaction that transforms an antecedent into a cause. This perspective offers a way to replace unsustainable mechanistic notions of causality with a dynamic, subject-centered approach.
