The separation of science and non-science is not only artificial but also detrimental to the advancement of knowledge. If we want to understand nature, if we want to master our physical surroundings, then we must use all ideas, all methods, and not just a small selection of them.

The idea of a method that contains firm, unchanging, and absolutely binding principles for conducting the business of science meets considerable difficulty when confronted with the results of historical research. We find, then, that there is not a single rule, however plausible, and however firmly grounded in epistemology, that is not violated at some time or another.

Rational discourse is only one way of presenting and examining an issue and by no means the best. Our new intellectuals are not aware of its limitations and of the nature of the things outside.

The best education consists in immunizing people against systematic attempts at education.

Science is an essentially anarchic enterprise.

Mathematical Reasoning is not only exact; it has its own criteria of reality.

A Universal Good should reflect the reality of the individual benefits that are collected under its name, not the other way around.
