To many an Englishman the human head seems too luxuriant. With its quantities of superfluous words and ideas, it grows periodically hot and messy, and needs a thorough cropping and scrubbing. To this end, William of Occam long ago invented his razor: _entia non multiplicanda praeter necessitatem_; a maxim calculated to shave the British inner man clean, and make a roundhead of him, not to say a blockhead. That everything is "nothing but" something else, probably inferior to it, became in time a sort of refrain in his politics and philosophy. He saw that reflection was constantly embroidering on the facts; but did he suppose that the pattern of things was really simpler than that of ideas, or did he feel that, however elaborate things might be, thought at least might be simple? At any rate, he aimed instinctively at economy of terms, retrenchment in belief, reduction of theory to the irreducible minimum. If theory was not useful, what was the use of it? And certainly all that can be said for some theories is that perhaps they are useful; and when ideas are merely useful, being worthless in themselves and absorbing human caloric, the less we require of them the better. Thought might then be merely a means to a life without thought, and belief a door to a heaven where no beliefs were expected; all speech might be like the curt words one says to the waiter, in the hope of presently dining in silence; and all looking might be looking out, as in crossing a crowded street, ending in the blessed peace of not having to look any more.
