As for Doing-good,that is one of the professions which are full. Moreover, I have tried itfairly, and, strange as it may seem, am satisfied that it does not agreewith my constitution. Probably I should not consciously and deliberatelyforsake my particular calling to do the good which society demands ofme, to save the universe from annihilation; and I believe that a likebut infinitely greater steadfastness elsewhere is all that now preservesit.
