“The most essential characteristic of scientific technique is that it proceeds from experiment, not from tradition.”

Autobiography (1936; 1949; 1958)
Context: Russia apart, the theory and philosophy of Marxism lightened up many a dark corner of my mind. History came to have a new meaning for me. The Marxist interpretation threw a flood of light on it... It was the essential freedom from dogma and the scientific outlook of Marxism that appealed to me. p. 362-363

Context: A principal characteristic of technique … is its refusal to tolerate moral judgments. It is absolutely independent of them and eliminates them from its domain. Technique never observes the distinction between moral and immoral use. It tends on the contrary, to create a completely independent technical morality.
Here, then, is one of the elements of weakness of this point of view. It does not perceive technique's rigorous autonomy with respect to morals; it does not see that the infusion of some more or less vague sentiment of human welfare cannot alter it. Not even the moral conversion of the technicians could make a difference. At best, they would cease to be good technicians. This attitude supposes further that technique evolves with some end in view, and that this end is human good. Technique is totally irrelevant to this notion and pursues no end, professed or unprofessed.
