Plutarch, De recta ratione audiendi
Goodwin, Ed.

To contempt is opposed admiration, which indeed argues a more candid and better disposition; but even in this case no small care is to be observed, and perhaps even greater. For although such as are contemptuous and self-conceited receive but little good from what they hear, yet the good-natured and such as are given to admire every thing take a great deal of harm. And Heraclitus was not mistaken when he said that a fool was put in a flutter at every thing he heard. We ought indeed to use all the candor imaginable in praising the speaker, yet withal as great caution in yielding our assent to what he says; to look upon his expression and action with a favorable construction, but to inspect the usefulness and truth of his doctrine with the nicest and most critical judgment; that speakers may cease to be malicious, and that what they say may do no mischief. For many false and dangerous principles steal upon us through the authority of the speaker and our own credulity. The Spartan Ephors, approving the judgment of one of an ill conversation, ordered it to be communicated to the people by a person of better life [p. 449] and reputation; thereby wisely and politicly using them to give more deference to the morals than to the words of such as pretend to advise them. But now in philosophy the reputation of the speaker must be pulled off, and his words examined naked and without a mask; for in hearing as in war there are many false alarms. The hoary head of the speaker or his gesture, his magisterial look or his assuming pride, and above all the noise and clapping of the auditory, bear great sway with a raw and inexperienced hearer, who is easily carried away with the tide. The very expression, if sweet and full and representing things with some pomp and greatness, has a secret power to impose upon us. For, as many lapses in such as sing to an instrument escape the hearers, so luxuriancy and pomp of style dazzle the hearer so that he cannot see clearly the argument in hand. And Melanthius, as it is said, being asked his opinion concerning a tragedy of Diogenes, made answer that the words intercepted his sight of it. But most Sophists in their declamations and speeches not only make use of words to veil and muffle their design; but with affected tone and softness of voice they draw aside and bewitch their followers, for the empty pleasure which they create reaping a more empty glory. So that the saying of Dionysius is very applicable to them, who, being one day extremely pleased with an harper that played excellently well before him, promised the fellow a great reward, yet afterwards would give him nothing, pretending he had hept his word; For, said he, as long as you pleased me by your playing, so long were you pleased by hope of the reward. And such also is the reward this kind of harangues bring to the authors. The hearers admire as long as they are pleased and tickled, but the satisfaction on one hand and glory on the other conclude with the oration; and the hearers lose their time idly, and the speakers their whole life.
