Problem saznanja

In considering all the main philosophical issues involved - how we know that something is a fact, that our senses and memory don't deceive us, that other people are conscious in the same way that we are - A. J. Ayer throws a clear light on the nature of our fundamental beliefs and provides an outstanding example of the philosophical mind at work.

"In this book I begin by taking the question of what is meant by knowledge as an example of a philosophical enquiry. Having maintained that to say one knows a fact is to claim the right to be sure of it. I show how such claims may be disputed on philosophical grounds ... The attempt to meet these objections supplies the main subject-matter for what is called the theory of knowledge; and different philosophical standpoints are characterized by the acceptance of denial of different stages in the sceptic's argument ... I also make some observations about philosophical method, the dimensions of time, causality, and personal identity."--Preface.
