Is there such a thing as a ‘Logic of Discovery’? Do we even have a consistent idea of such a thing? The approved answer to this seems to be “No.” Thus Popper argues (The Logic of Scientific Discovery) “The initial stage, the act of conceiving or inventing a theory, seems to me neither to call for logical analysis nor to be susceptible of it.” (p. 31.) Again, “… there is no such thing as a logical method of having new ideas, or a logical reconstruction of this process.” (p. 32.) Reichenbach writes that philosophy of science “… cannot be concerned with [reasons for suggesting hypotheses], but only with [reasons for accepting hypotheses].” (Experience and Prediction, p. 382.) Braithwaite elaborates: “The solution of these historical problems involves the individual psychology of thinking and the sociology of thought. None of these questions are our business here.” (Scientific Explanation, pp. 20, 21.)
