This text explores the ontological nature of events and their mutual relationships, starting from the premise that simple events must exist as a foundation for the formation of complex ones. Drawing on Leibniz’s Monadology, the author examines the conditions necessary for the emergence of complex events. A central theme is the critical reflection on the concept of randomness; the text questions whether events can occur purely by chance in an absolute sense, or if randomness is fundamentally a relative concept defined by specific contexts and perspectives. The analysis further focuses on how events interact with one another based on their spatio-temporal proximity. The quality and intensity of these interactions diminish as distance increases and are further constrained by the inherent sensitivity thresholds of the events involved. Ultimately, the document argues that complex events are not mere accidental clusters of simple occurrences but are results of structured interactions within a dynamic framework, where the capacity to react is a fundamental property of the events themselves.
