Naive falsificationism takes it for granted that the laws of nature are manifest an not hidden beneath disturbances of considerable magnitude. Empiri… - Paul Feyerabend

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.

Experts often arrive at different results, both in fundamental matters, and in application Who does not know of at least one case in his family where one doctor recommends a certain operation, another argues against it, while a third suggests an entirely different procedure? Who has not read of the debates about nuclear safety, the of the economy, the effects of pesticides, aerosol sprays, the efficiency of methods of education, the influence of race on intelligence? Two, three, five and even more views arise in such debates, and scientific supporters can be found for all of them. Occasionally one almost feels inclined to say: as many scientists, as many opinions. There are of course areas in which scientists agree- but this cannot raise our confidence. Unanimity is often the result of a political decision: dissenters are suppressed, or remain silent to preserve the reputation of science as a source of trustworthy and almost infallible knowledge. On other occasions, unanimity is the result of shared prejudices: positions are taken without detail examination of the matter under review and are infused with the same authority that proceeds from detailed research.

Arguments hardly affect the faithful- their beliefs have an entirely different foundation.
