Even scientific knowledge if there is anything to it is not a random observation of random objects for the critical objectivity of significant knowledge is attained as a practice only philosophically in inner action.

The real difference between a man's scientific judgments about himself and the judgment of others about him is he has added sources of knowledge.

From all this it follows what the general character of the problem of the development of a body of scientific knowledge is in so far as it depends on elements internal to science itself.

But the scientific importance of a change in knowledge of fact consists precisely in j its having consequences for a system of theory.

Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.

Scientific knowledge is a kind of discourse.

Distinguishing the signal from the noise requires both scientific knowledge and self-knowledge.

Knowledge is what we get when an observer preferably a scientifically trained observer provides us with a copy of reality that we can all recognize.

The product of the scientific imagination is a new vision of relations - like that of artistic imagination.

The scientific imagination always restrains itself within the limits of probability.
