"And if we consider seriously and correctly the nature of vows, we shall, unless I am much mistaken, come to the conclusion that it is perfectly sane, and even sensible, to swear to chain mountains together, and that, if insanity is involved at all, it is a little insane not to do so. The man who makes a vow makes an appointment with himself at some distant time or place. The danger of it is that himself should not keep the appointment. And in modern times this terror of one's self, of the weakness and mutability of one's self, has perilously increased, and is the real basis of the objection to vows of any kind. A modern man refrains from swearing to count the leaves on every third tree in Holland Walk, not because it is silly to do so (he does many sillier things), but because he has a profound conviction that before he had got to the three hundred and seventy-ninth leaf on the first tree he would be excessively tired of the subject and want to go home to tea."
