Men who have an elaborate philosophical defence of their views sometimes take pleasure in boasting of their almost babyish credulity. Having reached their own goal through labyrinths of logic, they will point the stranger only to the very shortest short cut of authority; merely in order to shock the simpleton with simplicity. Or, as in the present case, they will find a grim amusement in presenting the separate parts of the scheme as if they were really separate; and leave the outsider to make what he can of them.

So when somebody says that a fast is the opposite to a feast, and yet both seem to be sacred to us, some of us will always be moved merely to say, “Yes,” and relapse into an objectionable grin. When the anxious ethical enquirer says, “Christmas is devoted to merry-making, to eating meat and drinking wine, and yet you encourage this pagan and materialistic enjoyment,” you or I will be tempted to say, “Quite right, my boy,” and leave it at that. When he then says, looking even more worried, “Yet you admire men for fasting in caves and deserts and denying themselves ordinary pleasures; you are clearly committed, like the Buddhists, to the opposite or ascetic principle,” we shall be similarly inspired to say, “Quite correct, old bean,” or “Got it first time, old top,” and merely propose an adjournment for convivial refreshment.

Nevertheless, it is a temptation to be resisted
