Aristotle on Striving to Live as Immortals
We must not follow those who advise us, being men, to think of human things, and being mortal, of mortal things, but must, so far as we can, make ourselves immortal, and strain every nerve to live in accordance with the best thing in us; for even if it be small in bulk, much more does it in power and worth surpass everything.
Aristotle, Ethics 1177b33-78a3
