What were William James' criticisms of philosophy as a means of discovering truth?

Question

What were his main objections? Please be as brief as possible.

Answer 1

the sciences make steady progress and yield applications of matchless vitality-pholosophy makes no progress and not pratical applications and secondly philosophy is out of touch with real life, for which it substitutes abstractions. Philosophers have almost without acception, treated it as noble, simple, and perfectly ignoring the complexity of fact.
