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.
