Any religion that cannot be founded on half a sheet of note-paper will be bottom-heavy, and this, in a matter so essentially of sentiment as religion, is as bad as being top-heavy in a material construction. It must of course catch on to reason, but the less it emphasises the fact the better. Logic Logic has no place save with that which can be defined in words. It has nothing to do, therefore, with those deeper questions that have got beyond words and consciousness. To apply logic here is as fatuous as to disregard it in cases where it is applicable. The difficulty lies, as it always does, on the border lines between the respective spheres of influence. Logic and Faith Logic is like the sword—those who appeal to it shall perish by it. Faith is appealing to the living God, and one may perish by that too, but somehow one would rather perish that way than the other, and one has got to perish sooner or later. Common Sense and Philosophy The voices of common sense and of high philosophy sometimes cross; but common sense is the unalterable canto fermo and philosophy is the variable counterpoint. First Principles It is said we can build no superstructure without a foundation of unshakable principles. There are no such principles. Or, if there be any, they are beyond our reach—we cannot fathom them; therefore, _qua_ us, they have no existence, for there is no other “is not” than inconceivableness by ourselves. There is one thing certain, namely, that we can have nothing certain; therefore it is not certain that we can have nothing certain. We are as men who will insist on looking over the brink of a precipice; some few can gaze into the abyss below without losing their heads, but most men will grow dizzy and fall. The only thing to do is to glance at the chaos on which our thoughts are founded, recognise that it is a chaos and that, in the nature of things, no theoretically firm ground is even conceivable, and then to turn aside with the disgust, fear and horror of one who has been looking into his own entrails. Even Euclid cannot lay a demonstrable premise, he requires postulates and axioms which transcend demonstration and without which he can do nothing. His superstructure is demonstration, his ground is faith. And so his _ultima ratio_ is to tell a man that he is a fool by saying “Which is absurd.” If his opponent chooses to hold out in spite of this, Euclid can do no more. Faith and authority are as necessary for him as for any one else. True, he does not want us to believe very much; his yoke is tolerably easy, and he will not call a man a fool until he will have public opinion generally on his side; but none the less does he begin with dogmatism and end with persecution.
