If we ask ourselves what is this wisdom which experience forces upon us, the answer must be that we discover the world is not constituted as we had supposed it to be. It is not that we learn more about its physical elements, or its geography, or the variety of its inhabitants, or the ways in which human society is governed. Knowledge of this sort can be taught to a child without in any way disturbing his childishness. In fact, all of us are aware that we once knew a great many things which we have since forgotten. The essential discovery of maturity has little if anything to do with information about the names, the locations, and the sequence of facts; it is the acquiring of a different sense of life, a different kind of intuition about the nature of things.
