This text explores the intricate relationship between freedom, causality, and contingency within the context of human action and ontology. The author critiques strict pancausalism and argues against equating freedom with mere contingency, as the latter remains dependent on specific subjective or objective perspectives. Instead, freedom is defined as a subject's genuine capacity to react in multiple ways under identical circumstances, which presupposes the existence of internally integrated subjects as independent sources of activity. The study proposes a significant ontological shift: rather than viewing causality through the traditional cause-and-effect model, it interprets reactibility as the underlying source of what is commonly perceived as a causal nexus. This approach allows for the explanation of genuine novelty, not as a marginalized accident or systemic failure, but as an expression of an original leeway that constitutes the primary level of freedom. This conceptual transition moves beyond deterministic frameworks, emphasizing the central role of individual activity and integrity in the process of responding to the environment.
