If you look back on your own education, I am sure it will not be the full, vivid, instructive hours of truantry that you regret; you would rather cancel some lack-lustre periods between sleep and waking in the class. For my own part, I have attended a good many lectures in my time… But though I would not willingly part with such scraps of science, I do not set the same store by them as by certain other odds and ends that I came by in the open street while I was playing truant… Suffice it to say this: if a lad does not learn in the streets, it is because he has no faculty of learning. Nor is the truant always in the streets, for if he prefers, he may go out by the gardened suburbs into the country. He may pitch on some tuft of lilacs over a burn, and smoke innumerable pipes to the tune of the water on the stones. A bird will sing in the thicket. And there he may fall into a vein of kindly thought, and see things in a new perspective. Why, if this be not education, what is?
