Persuasion
the act of influencing the judgment and passions by arguments or motives. It is different from conviction. Conviction affects the understanding only; persuasion the will and practice. It is more extensively used than conviction, which last is founded on demonstration, natural or supernatural. But all things of which we may be persuaded are not capable of demonstration. Eloquence is but the art of persuasion. See Blair, Rhetoric; Maury, Principles of Eloquence; Pulpit Orator.
