This text explores why an established philosopher should read the works of others, emphasizing that philosophy is a journey rather than a static position. The author argues that reading serves as a vital source of inspiration, requiring a specific pre-selection of texts. Interestingly, the text suggests that thinkers who are fundamentally different might be more inspiring than those with similar views. While reading similar thinkers poses the risk of reinforcing existing errors, engaging with a different school of thought forces a philosopher to re-examine their own foundations and methodology. This critical distance prevents intellectual complacency. However, the author insists that for such a confrontation to be fruitful, the other thinker must be a genuine, first-rate philosopher. Ultimately, the dialogue with the other is presented as an essential mechanism for testing the resilience and depth of one's own philosophical path and ensuring that one's core principles are sound.
