…[T]he claim that philosophy represents a cognitive wheel that spins on its axis without moving anywhere is based on a mistaken view of philosophy. If philosophy spins on its own axis, this is because the fundamental problems that confront human beings remain basically the same through time and across space. What is the nature of things? What can I know, and how do I know it? How should I live my life? These are among the perennial problems of human existence that confront every culture in every era. They are recurring problems that must be addressed anew, not only by every generation, but by every reflective person.
