ABSTRACT
Aristotle realized that human beings are insatiable in their search for knowledge. We know that the human brain is one of the products of the evolution of life on the planet. And evolution has prepared us well for some of life’s most crucial challenges, such as survival and reproduction, but our brains are not so well equipped for solving problems of logic and often make incorrect inferences. But despite this they are inferences that we would prefer to avoid. Thus, one of the classical philosophical questions is whether knowledge is possible. Sceptics down the centuries, from Pyrrho and Sextus Empiricus to a number of post-modern authors (who, it should be said, are somewhat ill-informed in scientific terms), while accepting Aristotle’s premise, have concluded that the desire for knowledge that drives humans is impossible to satisfy. This is a theoretical attitude that has its own personality in the political sphere.
