This text examines the ontological status of possibility and its complex relationship with causality and time. The author highlights a fundamental paradox: if a possibility is regarded as already being, it contradicts its nature of preceding realization; yet, if it is regarded as non-being, it cannot serve as a cause. The inquiry explores how possibilities function alongside actual causes and the necessity of time for any transition from potentiality to reality. It challenges the notion of time as a static medium, suggesting instead that time is an ongoing arrival linked to events. Ultimately, the document proposes that possibilities arrive from the future, existing not merely as components of time but as distinct entities that allow for the emergence of consequences. This philosophical reflection invites a reconsideration of how the future influences the present through the arrival of possibilities, suggesting that the occurrence of events and the passage of time are deeply interconnected.
