Phaedrus

Socrates. So the lover will not, if he can help it, endure a beloved who is better than himself or his equal, but always makes him weaker and inferior; but the ignorant is inferior to the wise, the coward to the brave, the poor speaker to the eloquent, the slow of wit to the clever. Such mental defects, and still greater than these, in the beloved will necessarily please the lover, if they are implanted by Nature, and if they are not, he must implant them or be deprived of his immediate enjoyment. And he is of necessity jealous and will do him great harm by keeping him from many advantageous associations, which would most tend to make a man of him, especially from that which would do most to make him wise. This is divine philosophy, and from it the lover will certainly keep his beloved away, through fear of being despised; and he will contrive to keep him ignorant of everything else and make him look to his lover for everything, so that he will be most agreeable to him and most harmful to himself. In respect to the intellect, then, a man in love is by no means a profitable guardian or associate. We must next consider how he who is forced to follow pleasure and not good will keep the body of him whose master he is, and what care he will give to it. He will plainly court a beloved who is effeminate, not virile, not brought up in the pure sunshine, but in mingled shade, unused to manly toils and the sweat of exertion, but accustomed to a delicate and unmanly mode of life, adorned with a bright complexion of artificial origin, since he has none by nature, and in general living a life such as all this indicates, which it is certainly not worth while to describe further. We can sum it all up briefly and pass on. A person with such a body, in war and in all important crises, gives courage to his enemies, and fills his friends, and even his lovers themselves, with fear. This may be passed over as self-evident, but the next question, what advantage or harm the intercourse and guardianship of the lover will bring to his beloved in the matter of his property, must be discussed.
