Remarks about Hearing in general.
Of this Theophrastus affirms, that it is the most sensitive of all the senses. For the several objects of sight, tasting, and feeling do not excite in us so great disturbances and alterations as the sudden and frightful noises which assault us only at the ears. Yet in reality this sense is more rational than sensitive. For there are many organs and other parts of the body which serve as avenues and inlets to the soul to give admission to vice; there is but one passage of virtue into young minds, and that is by the ears, provided they be preserved all along free from the corruptions of flattery and untainted with lewd discourses. For this reason Xenocrates was of opinion that children ought to have a defence fitted to their ears rather than fencers or prize-players, because the ears only of the latter suffered by the blows, but the morals of the former were hurt and maimed by words. Not that he thereby recommended deafness, or forbade that they should be suffered to hear at all; but he advised only that debauchery might be kept out, till better principles, like so many guardians appointed by philosophy, had taken charge of that part which is so liable to be drawn aside and corrupted by discourse. And Bias of old, being ordered by Amasis to send him the best and withal the worst part of the sacrifice, sent the tongue; because the greatest benefits and disadvantages are derived to us thereby. Thus again many diverting themselves with children touch their ears, bidding them return the like again; by which they seem to intimate to them that such best deserve their love and esteem whose obligations enter at the ears. This is evident, that he that has lain fallow all his days, without tasting instruction, will not only prove barren and unfruitful of virtue, but very inclinable to vice; for an uncultivated mind, like untilled ground, will soon be overrun with weeds. For if that violent propensity of the mind to pleasure, and jealousy of all that carries any show of pain,—which proceed not from external causes or received prejudices, but are the natural springs of evil affections and infinite diseases of the mind,—are suffered to take their course, and not restrained, or diverted some other way by wholesome instructions, there can be no beast so savage that it may not be called tame and civilized in respect of such a man.
