This text presents a critical analysis and deconstruction of the traditional scholastic premise "operari sequitur esse," which asserts that being precedes any form of action. The author argues that this principle is based on the flawed assumption that an entity is a statically given whole and that activity is directed only outwards. In reality, every entity is an event-based process that must actively perform its being throughout its entire duration. Being is therefore not a mere state but a performance in itself. The reflection leads to a provocative reversal of the original thesis to "esse sequitur operari," suggesting that being follows the activity that constitutes it. However, the author also emphasizes that this process does not emerge from a vacuum. For the performance of being to begin, a certain "germ" or ontological starting point must be present to allow for the birth of the entity in time. This inquiry thus redefines the relationship between existence and activity within a process-oriented ontology.
