themselves are not in the least certain who among them is the most expert. And at that, the expert, even when we can identify him, is, likely as not, too busy to be consulted, or impossible to get at. But there are people whom we can identify easily enough because they are the people who are at the head of affairs. Parents, teachers, and masterful friends are the first people of this sort we encounter. Into the difficult question of why children trust one parent rather than another, the history teacher rather than the Sunday school teacher, we need not try to enter. Nor how trust gradually spreads through a newspaper or an acquaintance who is interested in public affairs to public personages. The literature of psychoanalysis is rich in suggestive hypothesis.
At any rate we do find ourselves trusting certain people, who constitute our means of junction with pretty nearly the whole realm of unknown things. Strangely enough, this fact is sometimes regarded as inherently undignified, as evidence of our sheep-like, ape-like nature. But complete independence in the universe is simply unthinkable. If we could not take practically everything for granted, we should spend our lives in utter triviality. The nearest thing to a wholly independent adult is a hermit, and the range of a hermit's action is very short. Acting entirely for himself, he can act only within a tiny radius and for simple ends. If he has time to think great thoughts we can be certain that he has accepted without question, before he went in for being a hermit, a whole repertory of painfully acquired information about how to keep warm and how to keep from being hungry, and also about what the great questions are.
On all but a very few matters for short stretches in our lives, the utmost independence that we can exercise is to multiply the authorities to whom we give a friendly hearing. As congenital amateurs our quest for truth consists in stirring up the experts, and forcing them to answer any heresy that has the accent of conviction. In such a debate we can often judge who has won the dialectical victory, but we are virtually defenseless
