Abstract
It is helpful for any enterprise to stop occasionally and examine itself. Science has done this rather infrequently in its long and eventful history, and there has not been, in general, any continuity in these self-examinations. As a result the history of the philosophy of science has been a rather spotty affair. My belief is that the philosophy of science should also, at times, become self-critical. When a study is concerned primarily with methods of other disciplines it tends to underemphasize the role played by the methods which it itself uses. What is the method of the philosophy of science, and is it justifiable? Can there be a satisfactory study of science and can this be scientific?
