Percy W. Bridgman Quotes
The process that I want to call scientific is a process that involves the continual apprehension of meaning, the constant appraisal of significance accompanied by a running act of checking to be sure that I am doing what I want to do, and of judging correctness or incorrectness. This checking and judging and accepting, that together constitute understanding, are done by me and can be done for me by no one else. They are as private as my toothache, and without them science is dead.
Bridgman, Percy W. "Science: Public or Private?" Philosophy of Science, vol. 7, no. 1, 1940, p. 38.
