Ecclesiastes 6:6

Yea, though he live a thousand years twice told The weariness of life carries the thinker yet further. Carry it to the furthest point conceivable, and still the result is the same. The longer it is, the fuller of misery and woe. The thought finds, as before, a parallel in the speech of Solon to Crœsus (Herod. i. 32). The man goes to the same place, to the dark, dreary world of Sheol, perhaps even to a more entire annihilation than was implied in the Hebrew thought of that unseen world, as the abortive birth, with nothing but an accumulated experience of wretchedness. Depression could go no further. See the poem of Omar Khayyam in the Appendix.
