Now, life is defined in the case of animals by the power of feeling, in the case of man by the power of feeling or thought: but the power involves reference to its exercise; and it is in this exercise that the reality lies: life, then, in its reality, seems to be feeling or thinking.

Life, again, is one of the things that are good and pleasant in themselves; for it is determinate or formed, and the determinate or formed is of the nature of the good; but that which is naturally [or in itself] good is good to the good man. (And hence life seems to be pleasant to all men. But by life we must not understand a bad or corrupt life, or a life of pain; for such a life is formless, as are all its constituents. We shall endeavour, presently, to throw some light on the nature of pain.)

Life itself, then, is good and pleasant (as appears also from the fact that all desire it, and especially the good and the blessed; for life is most desirable to them, and their life is the most blessed).
