Objective evidence and certitude are doubtless very fine ideals to play with, but where on this moonlit and dream-visited planet are they found? I - William James

There is no doubt that healthy-mindedness is inadequate as a philosophical doctrine, because the evil facts which it positively refuses to account for are a genuine portion of reality; and they may after all be the best key to life's significance, and possibly the only openers of our eyes to the deepest levels of truth.

Is dogmatic or scholastic theology less doubted in point of fact for claiming, as it does, to be in point of right undoubtable? And if not, what command over truth would this kind of theology really lose if, instead of absolute certainty, she only claimed reasonable probability for her conclusions? If we claim only reasonable probability, it will be as much as men who love the truth can ever at any given moment hope to have within their grasp. Pretty surely it will be more than we could have had, if we were unconscious of our liability to err.

Possibilities that fail to get realized are, for determinism, pure illusions: they never were possibilities at all. There is nothing inchoate, it says, about this universe of ours, all that was or is or shall be actual having been from eternity virtually there. The cloud of alternatives our minds escort this mass of actuality withal is a cloud of sheer deceptions, to which 'impossibilities' is the only name that rightfully belongs.
