If you would stand well with a great mind, leave him with a favorable impression of yourself; if with a little mind, leave him with a favorable impression of himself.

The aphorism contrasts two kinds of intellect and the social strategies that appeal to each. A “great mind” is portrayed as secure enough to judge others on their merits; to “stand well” with such a person, you need only leave a good impression of your own character or abilities. A “little mind,” by contrast, is implied to be vain or insecure, preferring interactions that flatter and center the self; you win its favor by making it feel superior. The remark functions both as social advice and as a moral critique of vanity, suggesting that true greatness is compatible with generosity of judgment, while smallness seeks reassurance through ego-stroking.
