Abstract
Turning to the history of philosophical thought, I am surprised by the question what is knowledge? I am surprised because usually we do not reflect on our own knowledge; it appears to us as something obvious. And yet this question has disturbed people since the beginning philosophical thinlung. Moreover, at the time knowledge appeared as a subject full of aporiasintellectual difficulties and obvious contradictions of judgment. This led to the humiliating doubt that man could know anything about the world in which he lived and, thus, exposed, so to speak, the painful nerve of the cognitive aspirations of human reason
