Whether some good of the soul constitutes man's happiness?

Objections

Objection 1 : It would seem that some good of the soul constitutes man's happiness. For happiness is man's good. Now this is threefold: external goods, goods of the body, and goods of the soul. But happiness does not consist in external goods, nor in goods of the body, as shown above (Articles [4],5). Therefore it consists in goods of the soul.
Objection 2 : Further, we love that for which we desire good, more than the good that we desire for it: thus we love a friend for whom we desire money, more than we love money. But whatever good a man desires, he desires it for himself. Therefore he loves himself more than all other goods. Now happiness is what is loved above all: which is evident from the fact that for its sake all else is loved and desired. Therefore happiness consists in some good of man himself: not, however, in goods of the body; therefore, in goods of the soul.
Objection 3 : Further, perfection is something belonging to that which is perfected. But happiness is a perfection of man. Therefore happiness is something belonging to man. But it is not something belonging to the body, as shown above (Article [5]). Therefore it is something belonging to the soul; and thus it consists in goods of the soul.
