John Gray discusses the topic of relations between the sciences and humanities, which is of great intrinsic importance all over the world. He argues that it is a mistake to think that social science can ever (or should) be modeled on natural sciences. They are different. They apply different types of phenomena - human beings are not machines, however complicated or unpredictable. They have reason for what they do, they are govern by their view of the world, their (right or wrong) beliefs. And the attempt to model human action on a kind of methodology which is derived from natural science is an error.
