Plato on ... (amv)

... constant intertemporal preferences in Arrow-Debreu or rational expectations economies:

"A man is said to be the same person from childhood until he is advanced in years: yet though he is called the same he does not at any time possess the same properties; he is continually becoming a new person . . . not only in his body but in his soul besides we find none of his manners or habits, his opinions, desires, pleasures, pains or fears, ever abiding the same in his particular self, some things grow in him while others perish." (Symposium, 207D–208B)
