This paper explores event ontology, a foundational philosophy of the materialist worldview, and presents an analysis of Nietzsche’s philosophical materialism, drawing upon his late notebooks, particularly his project on the Will to Power. Our approach situates Nietzsche’s perspective within the metaphysical direction of immanent materialism, and we draw connections between his ideas and the materialist monism of Russell, the process ontology of Whitehead, and the ontology of individuation developed by Simondon. The paper contributes to ongoing discussions on materialism in philosophy (...) and sheds light on the intersection of Nietzsche’s thought with other prominent materialist theories. (shrink)
