Far from being magisterial in its objectivity, science was conditioned by history, society, and the prejudices of scientists.

History, if viewed as a repository for more than anecdote or chronology, could produce a decisive transformation in the image of science by which we are now possessed.

As in political revolutions, so in paradigm choice-there is no standard higher than the assent of the relevant community... this issue of paradigm choice can never be unequivocally settled by logic and experiment alone.

The historian of science may be tempted to exclaim that when paradigms change, the world itself changes with them.

Far from being magisterial in its objectivity, science was conditioned by history, society, and the prejudices of scientists.

The decision to reject one paradigm is always simultaneously the decision to accept another, and the judgment leading to that decision involves the comparison of both paradigms with nature and with each other.

Rather than being an interpreter, the scientist who embraces a new paradigm is like the man wearing inverting lenses.
