Truth lives, in fact, for the most part on a credit system. Our thoughts and beliefs pass, so long as nothing challenges them, just as bank-notes pass so long as nobody refuses them.

As a rule we disbelieve all the facts and theories for which we have no use.

Volition . . . takes place only when there are a number of conflicting systems of ideas, and depends on our having a complex field of consciousness.
