The text explores the nature of assumptions that serve as the necessary foundation for all human thought and action. The author asserts that nothing begins entirely from scratch; every novelty is situated within a framework of prerequisites. These assumptions may be consciously recognized, unknown to the thinker, or revealed only after centuries as hidden but essential conditions for specific intellectual processes. A central critique is directed at the European philosophical tradition, which erroneously presumes that such foundations must be anchored in the past or a primordial past as something given and fixed. This tendency to seek necessity in pre-existing structures is evident throughout continental thought, from medieval realism to Descartes' innate ideas, Leibniz's pre-established harmony, and Kant's apriori. The text suggests that this reliance on retrospective inevitability burdens European thinking and calls for a re-evaluation of how we understand the constitutive elements that shape reason itself.
