Whether the body is necessary for man's happiness?

Objections

Objection 1 : It would seem that the body is necessary for Happiness. For the perfection of virtue and grace presupposes the perfection of nature. But Happiness is the perfection of virtue and grace. Now the soul, without the body, has not the perfection of nature; since it is naturally a part of human nature, and every part is imperfect while separated from its whole. Therefore the soul cannot be happy without the body.
Objection 2 : Further, Happiness is a perfect operation, as stated above (Question [3], Articles [2],5). But perfect operation follows perfect being: since nothing operates except in so far as it is an actual being. Since, therefore, the soul has not perfect being, while it is separated from the body, just as neither has a part, while separate from its whole; it seems that the soul cannot be happy without the body.
Objection 3 : Further, Happiness is the perfection of man. But the soul, without the body, is not man. Therefore Happiness cannot be in the soul separated from the body.
Objection 4 : Further, according to the Philosopher (Ethic. vii, 13) "the operation of bliss," in which operation happiness consists, is "not hindered." But the operation of the separate soul is hindered; because, as Augustine says (Gen. ad lit. xii, 35), the soul "has a natural desire to rule the body, the result of which is that it is held back, so to speak, from tending with all its might to the heavenward journey," i.e. to the vision of the Divine Essence. Therefore the soul cannot be happy without the body.
Objection 5 : Further, Happiness is the sufficient good and lulls desire. But this cannot be said of the separated soul; for it yet desires to be united to the body, as Augustine says (Gen. ad lit. xii, 35). Therefore the soul is not happy while separated from the body.
Objection 6 : Further, in Happiness man is equal to the angels. But the soul without the body is not equal to the angels, as Augustine says (Gen. ad lit. xii, 35). Therefore it is not happy.
