Note 1 — LXVIII Of a question which a young man proposed to Aristotle

Aristotle replied: I cannot do other than tell you that when the nature of man grows old, the good natural heat changes into weakness, while the reasonable virtue fails and alters1. For your instruction I will teach you what I can. Do so that in your youth you practice all beautiful, pleasant and honest things, and guard yourself from indulging in what is contrary to these; so when you are old, you will live without evil, not from nature or from reason, but owing to the long pleasant and noble habit you have formed.
