Peter Medawar Thinking Quotations

The alternative to thinking in evolutionary terms is not to think at all.

The purpose of scientific enquiry is not to compile an inventory of factual information, nor to build up a totalitarian world picture of natural Laws in which every event that is not compulsory is forbidden. We should think of it rather as a logically articulated structure of justifiable beliefs about nature.
