luck, in which a man may think he believes rather than in a particular
career that may be awaiting him. Now since this entity, luck, is a
mere word, confidence in it, to be justified at all, must be
transferred to the concrete facts it stands for. Faith in one's luck
must be pragmatic, but simply because faith in such an entity is not
needful nor philosophical at all. The case is the same with working
hypotheses, when that is all they are; for on this point there is some
confusion. Whether an idea is a working hypothesis merely or an
anticipation of matters open to eventual inspection may not always be
clear. Thus the atomic theory, in the sense in which most philosophers
entertain it to-day, seems to be a working hypothesis only; for they
do not seriously believe that there are atoms, but in their ignorance
of the precise composition of matter, they find it convenient to speak
of it as if it were composed of indestructible particles. But for
Democritus and for many modern men of science the atomic theory is not
a working hypothesis merely; they do not regard it as a provisional
makeshift; they regard it as a probable, if not a certain,
anticipation of what inspection would discover to be the fact, could
inspection be carried so far; in other words, they believe the atomic
theory is true. If they are right, the validity of this theory would
not be that of pragmatic "truth" but of pragmatic "fact"; for it would
be a view, such as memory or intuition or sensation might give us, of
experienced objects in their experienced relations; it would be the
communication to us, in a momentary dream, of what would be the
experience of a universal observer. It would be knowledge of reality
in M. Bergson's sense. Pragmatic "truth," on the contrary, is the
relative and provisional justification of fiction; and pragmatism is
not a theory of truth at all, but a theory of theory, when theory is
instrumental.
