Now the presence of envy, attended by malice and hostility, is not a good thing for any undertaking, but it stands in the way of all that is honourable; and it is the very worst associate and counsellor for one that would listen to a lecture, inasmuch as it makes what is profitable to be vexatious, unpleasing, and unacceptable, because envious persons are pleased with anything rather than with the good points of a discourse. Now the man that is stung by the wealth, or repute, or beauty possessed by another, is merely envious; for he is depressed by the good fortune of others; but one who feels discontentment at an excellent discourse is vexed by what is for his own good. For just as light is a good thing for those who can see, so is discourse for those who can hear, if they be willing to receive it. Now while envy in other matters is engendered by certain untrained and evil dispositions of a man, the envy that is directed against a speaker is the offspring of an unseasonable desire for repute and a dishonest ambition, and it does not suffer the person in such a mood even to pay attention to what is being said, but it confuses and distracts his mind which at one moment is engaged in reviewing its own condition to see whether it be inferior to that of the speaker, then anon it turns to dwell on the other persons present to see whether they are showing any pleasure or admiration; it is disconcerted by their approval, and irritated at the audience if they find the speaker acceptable; disregards and dismisses the part of the discourse already delivered because the memory of it is painful, but for what still remains trembles with anxiety lest that part prove better than the part already delivered; eager that the speakers may most quickly have done when they are speaking most excellently; and when the lecture is over, it does not ponder upon any point of the discussion, but proceeds to count as votes the comments and attitudes of those present; if any approve, fleeing and recoiling from these as though frantic; if any disapprove or distort the things said, hastening to join their company; and if it be impossible to distort, then it falls to making comparisons with others who could have spoken better and more forcibly to the same purport—until by spoiling and maltreating the lecture it has succeeded in making the whole thing useless and unprofitable to itself.
