This text offers a critical reflection on the Cartesian conception of philosophical method, which advocates for the radical rejection of all prior knowledge in pursuit of absolute certainty. The author argues that this approach is fundamentally flawed because it overlooks the historical context and the actual nature of an individual's intellectual development. Philosophy should not be viewed as a mere logical derivation from fixed principles, but rather as a journey punctuated by crossroads that a thinker encounters through active dialogue and confrontation with other authors. Attempting an absolute intellectual restart leads to stagnation; without the context of prior experience or engagement with differing perspectives, an individual cannot identify their own errors, which may falsely appear as self-evident truths. Genuine philosophical growth is thus contingent upon a direct and sincere dialogue with great thinkers, allowing for the continuous verification of both one's own and others' intellectual steps. This dialogical process constitutes the essence of authentic philosophical inquiry.
