In Shaw's notes to Caesar and Cleopatra by Shaw it is written about Julius Caesar:
He understands the paradox of money, and gives it away when he can get most for it: in other words, when its value is least, which is just when a common man tries hardest to get it.
What might be meant here by the paradox of money? Is there any event in Julius Casear's life (perchance alluded to in the play) that points to such understanding of money?
