This article is not intended to state what I positively believe to be true, but to make a suggestion which I think it well-worth working out. The suggestion is not altogether unfamiliar, but it has certain implications that seem to have been so far overlooked, or at any rate have never been developed. I do not think that it is the duty of a philosopher to confine himself in his publications to working out theories of the truth of which he is convinced.… It is a part of a philosopher's work, as it is of a scientist's, to try out tentative hypotheses and examine their advantages and disadvantages (Ewing 1939, p. 1).
