Science is not sacrosanct. The mere fact that it exists, is admired, has results is not sufficient for making it a measure of excellence. Modern scie… - Paul Feyerabend

Science is an essentially anarchic enterprise: theoretical anarchism is more humanitarian and more likely to encourage progress than its law-and-order alternatives.

Even bold and revolutionary thinkers bow to the judgment of science. Kropotkin wants to break up all existing institutions, but he does not touch science. Ibsen goes very far in his critique of bourgeois society, but he retains science as a measure of truth. Levi Strauss has made us realize that Western thought is not the lonely peak of human achievement it was once thought to be, but he and his followers exclude science from their relativization of ideologies. Marx and Engels were convinced that science would aid the workers in their quest for mental and social liberation.

It is clear, then, that the idea of a fixed method, or of a fixed theory or rationality, rests on too naive a view of man and his social surroundings. To those who look at the rich material provided by history, and who are not intent on impoverishing it in order to please their lower instincts, their craving for intellectual security in the form of clarity, precision, "objectivity", "truth", it will become clear that there is only one principle that can be defended under all circumstances and in all stages of human development. It is the principle: anything goes.
