Aquinas on Effeminacy

Aquinas lists effeminacy as a vice opposed to perseverance. (ST II-II, Q. 138, A.1)

Article 1. Whether effeminacy is opposed to perseverance?

Effeminacy: Mollities, literally 'softness'

Objection 1. It seems that effeminacy is not opposed to perseverance. For a gloss on 1 Corinthians 6:9-10, "Nor adulterers, nor the effeminate, nor liers with mankind," expounds the text thus: "Effeminate--i.e. obscene, given to unnatural vice." But this is opposed to chastity. Therefore effeminacy is not a vice opposed to perseverance.

Objection 2. Further, the Philosopher says (Ethic. vii, 7) that "delicacy is a kind of effeminacy." But to be delicate seems akin to intemperance. Therefore effeminacy is not opposed to perseverance but to temperance. 

Objection 3. Further, the Philosopher says (Ethic. vii, 7) that "the man who is fond of amusement is effeminate." Now immoderate fondness of amusement is opposed to eutrapelia, which is the virtue about pleasures of play, as stated in Ethic. iv, 8. Therefore effeminacy is not opposed to perseverance.

On the contrary, The Philosopher says (Ethic. vii, 7) that "the persevering man is opposed to the effeminate."

I answer that, As stated above (II-II:137:1 and II-II:137:2), perseverance is deserving of praise because thereby a man does not forsake a good on account of long endurance of difficulties and toils: and it is directly opposed to this, seemingly, for a man to be ready to forsake a good on account of difficulties which he cannot endure. This is what we understand by effeminacy, because a thing is said to be "soft" if it readily yields to the touch. Now a thing is not declared to be soft through yielding to a heavy blow, for walls yield to the battering-ram. Wherefore a man is not said to be effeminate if he yields to heavy blows. Hence the Philosopher says (Ethic. vii, 7) that "it is no wonder, if a person is overcome by strong and overwhelming pleasures or sorrows; but he is to be pardoned if he struggles against them." Now it is evident that fear of danger is more impelling than the desire of pleasure: wherefore Tully says (De Offic. i) under the heading "True magnanimity consists of two things: It is inconsistent for one who is not cast down by fear, to be defeated by lust, or who has proved himself unbeaten by toil, to yield to pleasure." Moreover, pleasure itself is a stronger motive of attraction than sorrow, for the lack of pleasure is a motive of withdrawal, since lack of pleasure is a pure privation. Wherefore, according to the Philosopher (Ethic. vii, 7), properly speaking an effeminate man is one who withdraws from good on account of sorrow caused by lack of pleasure, yielding as it were to a weak motion.

Reply to Objection 1. This effeminacy is caused in two ways. On one way, by custom: for where a man is accustomed to enjoy pleasures, it is more difficult for him to endure the lack of them. On another way, by natural disposition, because, to wit, his mind is less persevering through the frailty of his temperament. This is how women are compared to men, as the Philosopher says (Ethic. vii, 7): wherefore those who are passively sodomitical are said to be effeminate, being womanish themselves, as it were.

Reply to Objection 2. Toil is opposed to bodily pleasure: wherefore it is only toilsome things that are a hindrance to pleasures. Now the delicate are those who cannot endure toils, nor anything that diminishes pleasure. Hence it is written (Deuteronomy 28:56): "The tender and delicate woman, that could not go upon the ground, nor set down her foot for . . . softness [Douay: 'niceness']." Thus delicacy is a kind of effeminacy. But properly speaking effeminacy regards lack of pleasures, while delicacy regards the cause that hinders pleasure, for instance toil or the like.

Reply to Objection 3. In play two things may be considered. On the first place there is the pleasure, and thus inordinate fondness of play is opposed to eutrapelia. Secondly, we may consider the relaxation or rest which is opposed to toil. Accordingly just as it belongs to effeminacy to be unable to endure toilsome things, so too it belongs thereto to desire play or any other relaxation inordinately.
