Since happiness means some manner of final perfection, happiness must have different meanings according to the different grades of perfection that there are attainable by different beings capable of happiness. In God is happiness by essence, because His very being is His activity, because He does not enjoy any other thing than Himself. In the angels final perfection is by way of a certain activity, whereby they are united to the uncreated good; and this activity is in them one and everlasting. In men, in the state of the present life, final perfection is by way of an activity whereby they are united to God. But this activity can not be everlasting or continuous, and by consequence it is not one, because an act is multiplied by interruption; and, therefore, in this state of the present life, perfect happiness is not to be had by man.
Hence the philosopher, placing the happiness of man in this life, says that it is imperfect, and after much discussion he comes to this conclusion: "We call them happy, so far as happiness can be predicated of men." But we have a promise from God of perfect happiness, when we shall be "like the angels in heaven." As regards this perfect happiness, the objection drops, because in this state of happiness the mind of man is united to God by one continuous and everlasting activity. But in the present life, so far as we fall short of the unity and continuity of such an activity, so much do we lose of the perfection of happiness. There is, however, granted us a certain participation in happiness, and the more continuous and undivided the activity can be the more will it come up to the idea of happiness. And therefore in the active life, which is busied with many things, there is less of the essence of happiness than in the contemplative life, which is busy with the one occupation of the contemplation of truth.
