All our learned schoolmasters and tutors are agreed that children do not know why they want what they want. But no one likes to think – blindingly obvious though it is, in my view – that grown-ups too, like children, totter around on the earth and, like the children, do not know where they have come from or where they are going, act no more than children do for any true purpose and are just as governed by biscuits, cakes, and the rod.
