8. Somebody might object that by subsisting till the present, the memory of the past adds something more to him who has long lived happily. In this case it will be necessary to examine what is meant by this memory. If it mean the memory of former wisdom, and if it mean that he who would possess this memory would become wiser on account of it, then this memory differs from our question (which studies happiness, and not wisdom). If it mean the memory of pleasure, it would imply that the happy man has need of much pleasure, and cannot remain satisfied with what is present. Besides, there is no proof that the memory of a past pleasure is at all pleasant; on the contrary, it would be entirely ridiculous to remember with delight having tasted a delicious dish the day before, and still more ridiculous remembering such an enjoyment ten years ago. It would be just as ridiculous to pride one self on having been a wise man last year. NOT EVEN THE MEMORY OF VIRTUE INCREASES HAPPINESS. 9. Could not the memory of virtuous actions contribute to happiness? No: for such a memory cannot exist in a man who has no virtue at present, and who thereby is driven to seek out the memory of past virtues. LENGTH OF TIME IS OF NO IMPORTANCE, NOT EVEN AS OPPORTUNITY OF VIRTUE. 10. Another objection is that length of time would give opportunity for doing many beautiful deeds; while this opportunity is denied him who lives happily only a short period. This may be answered by denying happiness to a man on the grounds of having done many beautiful deeds. If several parts of time and several actions are to constitute happiness, then it would be constituted by things that are no more, that are past, and by present things; whereas our definition of happiness limits it exclusively to the present. Then we considered whether length of time add to happiness. There remains only to examine whether happiness of long duration be superior because of yielding opportunities of doing more beautiful deeds. To begin with, the man who is inactive may be just as happy, if not more happy than he who is active. Besides, it is not actions themselves which yield happiness; (the sources of happiness) are states of mind, which are the principles of beautiful actions. The wise man enjoys welfare while active, but not because of this activity; he derives (this welfare) not from contingent things, but from what he possesses in himself. For it might happen even to a vicious man to save his fatherland, or to feel pleasure in seeing it saved by some other. It is not then these activities which are the causes of the enjoyment of happiness. True beatitude and the joys it yields must be derived from the constant disposition of the soul. To predicate it of activity, would be to make it depend on things alien to virtue and the soul. The soul's actualization consists in being wise, and in exercising her self-activity; this is true happiness. SECOND ENNEAD, BOOK SEVEN.
