It is true you can make your net of logical interpretation finer and finer, you can fine your classification more and more—up to a certain limit. But essentially you are working in limits, and as you come closer, as you look at finer and subtler things, as you leave the practical purpose for which the method exists, the element of error increases. Every species is vague, every term goes cloudy at its edges, and so in my way of thinking, relentless logic is only another phrase for a stupidity,—for a sort of intellectual pigheadedness. If you push a philosophical or metaphysical inquiry through a series of valid syllogisms—never committing any generally recognised fallacy—you nevertheless leave a certain rubbing and marginal loss of objective truth and you get deflections that are difficult to trace, at each phase in the process. Every species waggles about in its definition, every tool is a little loose in its handle, every scale has its individual error. So long as you are reasoning for practical purposes about the finite things of experience, you can every now and then check your process, and correct your adjustments. But not when you make what are called philosophical and theological inquiries, when you turn your implement towards the final absolute truth of things. Doing that is like firing at an inaccessible, unmarkable and indestructible target at an unknown distance, with a defective rifle and variable cartridges. Even if by chance you hit, you cannot know that you hit, and so it will matter nothing at all.
