What better immortality than in one's work left behind to move in men?
What more than this can life desire?
But Cleon does not agree with that.

"If thou, O king, with the light now in thee, hadst looked at creation before man appeared, thou wouldst have said, 'All is perfect so far.' But questioned if anything more perfect in joy might be, thou wouldst have said, 'Yes; a being may be made, unlike these who do not know the joy they have, who shall be conscious of himself, and know that he is happy.

Then his life will be satisfied with daily joy.'" O king, thou wouldst have answered foolishly.

The higher the soul climbs in joy the more it sees of joy, and when it sees the most, it perishes.

Vast capabilities of joy open round it; it craves for all it presages; desire for more deepening with every attainment.
