[Prejudice and evidence, oppositions and convergencies in today's psychiatry].

The notion of prejudice in epistemology starts in the early times of modern thought, together with the first reflections on science. Tracks of the notion of prejudice can be followed right up to our own days, all throughout the succession of epistemologies, with such notion always opposed to the notion of evidence. However, what in one epistemology stands for prejudice, is labeled as evidence in subsequent epistemologies, and the other way round. The present work aims at demonstrating the multivocal character of the evidence-prejudice schemas, and at critically reconsidering its use in present psychiatry.
