FIFTH ARTICLE [I-II, Q. 2, Art. 5]

Whether Man's Happiness Consists in Any Bodily Good?

Objection 1: It would seem that man's happiness consists in bodily

goods. For it is written (Ecclus. 30:16): "There is no riches above

the riches of the health of the body." But happiness consists in that

which is best. Therefore it consists in the health of the body.

Obj. 2: Further, Dionysius says (Div. Nom. v), that "to be" is better

than "to live," and "to live" is better than all that follows. But

for man's being and living, the health of the body is necessary.

Since, therefore, happiness is man's supreme good, it seems that

health of the body belongs more than anything else to happiness.

Obj. 3: Further, the more universal a thing is, the higher the

principle from which it depends; because the higher a cause is, the

greater the scope of its power. Now just as the causality of the

efficient cause consists in its flowing into something, so the

causality of the end consists in its drawing the appetite. Therefore,

just as the First Cause is that which flows into all things, so the

last end is that which attracts the desire of all. But being itself

is that which is most desired by all. Therefore man's happiness

consists most of all in things pertaining to his being, such as the

health of the body.

_On the contrary,_ Man surpasses all other animals in regard to

happiness. But in bodily goods he is surpassed by many animals; for

instance, by the elephant in longevity, by the lion in strength, by

the stag in fleetness. Therefore man's happiness does not consist in

goods of the body.

_I answer that,_ It is impossible for man's happiness to consist in

the goods of the body; and this for two reasons. First, because, if a

thing be ordained to another as to its end, its last end cannot

consist in the preservation of its being. Hence a captain does not

intend as a last end, the preservation of the ship entrusted to him,

since a ship is ordained to something else as its end, viz. to

navigation. Now just as the ship is entrusted to the captain that he

may steer its course, so man is given over to his will and reason;

according to Ecclus. 15:14: "God made man from the beginning and left

him in the hand of his own counsel." Now it is evident that man is

ordained to something as his end: since man is not the supreme good.

Therefore the last end of man's reason and will cannot be the

preservation of man's being.

Secondly, because, granted that the end of man's will and reason be

the preservation of man's being, it could not be said that the end of

man is some good of the body. For man's being consists in soul and

body; and though the being of the body depends on the soul, yet the

being of the human soul depends not on the body, as shown above (I,

Q. 75, A. 2); and the very body is for the soul, as matter for its

form, and the instruments for the man that puts them into motion,

that by their means he may do his work. Wherefore all goods of the

body are ordained to the goods of the soul, as to their end.

Consequently happiness, which is man's last end, cannot consist in

goods of the body.

Reply Obj. 1: Just as the body is ordained to the soul, as its end,

so are external goods ordained to the body itself. And therefore it

is with reason that the good of the body is preferred to external

goods, which are signified by "riches," just as the good of the soul

is preferred to all bodily goods.

Reply Obj. 2: Being taken simply, as including all perfection of

being, surpasses life and all that follows it; for thus being itself

includes all these. And in this sense Dionysius speaks. But if we

consider being itself as participated in this or that thing, which

does not possess the whole perfection of being, but has imperfect

being, such as the being of any creature; then it is evident that

being itself together with an additional perfection is more

excellent. Hence in the same passage Dionysius says that things that

live are better than things that exist, and intelligent better than

living things.

Reply Obj. 3: Since the end corresponds to the beginning; this

argument proves that the last end is the first beginning of being, in

Whom every perfection of being is: Whose likeness, according to their

proportion, some desire as to being only, some as to living being,

some as to being which is living, intelligent and happy. And this

belongs to few.
