A quote
Let me take it at its word, and let it make the most of the advantages it possesses. The mind bids me do some thinking and consider how much of this peace of spirit and moderation of character I owe to wisdom and how much to my time of life; it bids me distinguish carefully what I cannot do and what I do not want to do. . . . For why should one complain or regard it as a disadvantage, if powers which ought to come to an end have failed?
