What good is a life lived as if it made no difference at all to the great life of the world? A sadder thing I cannot imagine. Why should not a mother say to herself, if I raise this child aright, if I love and care for her, she shall live a life that brings joy to those about her, and thus I have changed the world? Why should not the farmer that plants a seed say to his neighbor, this seed I plant today will feed someone, and that is how I change the world today?” “This is philosophy, Fool. I have never had time to study such things.”
