This reflection draws upon Heraclitus's fragments regarding the relationship between polymathy and genuine wisdom. The author explores the apparent tension between these concepts, suggesting that while the mere accumulation of information does not lead to rationality, pure thinking devoid of broad perspective tends toward dangerous simplification of reality. Using a personal anecdote about breeding Drosophila during the war, the author demonstrates how practical experience in genetics provided a defense against post-war Lysenkoism, which relied on ideological pseudo-philosophy. The text emphasizes that for a philosopher, the goal is not an encyclopedic collection of facts but rather a fundamental "wide-angle" perspective. This breadth involves a necessary openness to the world of facts and the current state of sciences, including fields like biology and economics. Ultimately, true philosophical orientation requires both depth of thought and a sufficiently broad horizon of experience to effectively prevent ideological distortion, intellectual simplifications, and isolation within a single field of study.
