"If one aims to judge political movements, their deeds are far more important than their speeches, which are often masking rather than revealing."

“At all times pseudoprofound aphorisms have been more popular than rigorous arguments.”

“The motto of science is not just Pauca but rather Plurima ex paucissimis — the most out of the least.”

“A definitely undesirable rationale sustaining the cult of simplicity is of a metaphysical nature: namely, the wish to attain the ultimate atoms of experience and/or reality ... this drive, which feeds metaphysical fundamentalism, is dangerous because it leads to postulating the final simplicity of some form of experience or some kind of substance thereby barring any inquiry into their structure.”

“The fact that a great many scientists signed Faustian pacts with the war devil throughout the twentieth century has given science a bad name, and has discouraged many able youngsters from pursuing a scientific career.”

“Logical positivism was progressive compared with the classical positivism of Ptolemy, Hume, d'Alembert, Compte, John Stuart Mill, and Ernst Mach. It was even more so by comparison with its contemporary rivals—,,,,, and existentialism. However, neo-positivism failed dismally to give a faithful account of science, whether natural or social. It failed because it remained anchored to sense-data and to a phenomenalist metaphysics, overrated the power of induction and underrated that of hypothesis, and denounced realism and materialism as metaphysical nonsense. Although it has never been practiced consistently in the advanced natural sciences and has been criticized by many philosophers, notably Popper , logical positivism remains the tacit philosophy of many scientists. Regrettably, the anti-positivism fashionable in the metatheory of social science is often nothing but an excuse for sloppiness and wild speculation.”
