QUOTE : If you would induce your hearer to adopt a given course, you must not only prove to his wisdom that it is the proper means to its end, but you must show to his heart that the end is desirable. Hence all suasive discourse, whatever its particular topic, may be reduced to two elements: that which places the proposition in the category of the true, and that which shows it in the category of the good. Both elements are essential to the oration. The latter may be present only by implication, but unless it is virtually present there is no rhetorical discourse.
