This text explores two opposing conceptions of causality, focusing on the view that cause and effect are distinct rather than identical. In this perspective, the causal nexus is an event characterized by change, as the effect is not pre-contained within the cause. However, this approach faces significant theoretical challenges, as famously noted by David Hume. If the transition between cause and effect involves a difference that is rationally incomprehensible, causality becomes a myth—a narrative describing recurring experiences rather than a logically demonstrable connection. The author highlights that while causality was originally intended to answer the question "why," this conception reduces it to merely observing "that" something occurs. Drawing on ancient Greek philosophy, the text distinguishes between empirical opinion (doxa) and true scientific knowledge (episteme). Even if an empirical observation is correct, it does not constitute genuine understanding if the underlying reason remains inaccessible. Ultimately, the text critically examines the limits of human reason in grasping the essence of causal relationships, which appear in our experience only as repeating patterns under similar conditions.
