Note 71 — ACT III., SCENE I.
Reading edition
Ingenious and ingenuous were formerly used indiscriminately for each other. [The truth seems to be that ingenuous was merely understood formerly in the sense in which we use it now, and that ingenious, on the contrary, had a larger meaning, standing generally for the gifts of the mind or intellect. Old-fashioned people only would say of such an one, "He's an ingenious man," meaning a person of intellectual culture.]
