Directions concerning Attention. Well then, silence is at all times a singular ornament of a youth, but especially if he does not interrupt the speaker nor carp and except at every thing he says, but patiently expects the conclusion, though his discourse be none of the best; and when he has done, if he does not presently come over him with an objection, but (as Aeschines directs) allows time to add, if he please, to what has been said, or to alter, or retract. Whereas such as turn too suddenly upon a speaker neither hear nor are heard themselves, but senselessly chatter to one another, and sin against the laws and rules of decorum. But he that brings along with him a modest and unwearied attention has this advantage, that whatever is beneficial in the discourse he makes his own, and he more readily discovers what is false or impertinent, appearing all the while a friend to truth rather than to squabbling or rashness. Therefore it was not ill said, that such as design to infuse goodness into the minds of youth must first exclude thence pride and self-conceit more carefully than we squeeze air out of bladders which we wish to fill with something useful; because, while they are puffed up with arrogance, there is no room to admit any thing else.
