“If you would win a man to your cause, first convince him that you are his sincere friend. Therein is a drop of honey that catches his heart, which…is the great high road to his reason, and which, when once gained, you will find but little trouble in convincing his judgment of the justice of your cause, if indeed that cause really be a just one. On the contrary, assume to dictate to his judgment, or to command his action, or to mark him as one to be shunned and despised, and he will retreat within himself, close all the avenues to his head and his heart; and tho’ your cause be naked truth itself . . . you shall no more be able to [reach] him, than to penetrate the hard shell of a tortoise with a rye straw.”
