Men spoke much in my boyhood about restricted or ruined men of genius: and it was common to say that many a man was a Great Might-Have-Been. To me it's a more solid and startling fact that any man in the street is a Great Might-Not-Have-Been.
Mankind must work continually to produce individual great human beings - this and nothing else is the task... for the question is this : How can your life, the individual life, retain the highest value, the deepest significance? Only by living for the good of the rarest and most valuable specimens.
Expect a most agreeable letter; for not being overburdened with subject (having nothing at all to say) I shall have no check to my Genius from beginning to end.
