Your outlook on life is so different from mine that I can hardly imagine you being built of the same stuff as myself. Yet I venture to put my difficulty before you. It is, of course, no question of mental grasp or capacity or artistic endowment. I am, so far as these are concerned, merely the man in the street, the averagely endowed and the ordinarily educated. I call myself a Puritan and a Christian. I run continually against walls of convention, of morals, of taste, which may be all wrong, but which I should feel it wrong to climb over. You range over fields where my make-up forbids me to wander.
