Lucretius on Philosophical pessimism

“So long as the object of our desire is wanting, it seems more important than anything else; but later, when it is ours, we covet some other thing; and so an insatiable thirst for life keeps us always openmouthed.”

“Consider too how a baby, like a shipwrecked sailor tossed ashore by the savage waves, lies on the ground naked, speechless, and utterly helpless, as soon as nature has cast it forth with pangs of labor from its mother's womb into the shores of light; and how it fills the place with its woeful wailings—as well it may, seeing that life holds so much sorrow in store for it.”

“How could it have harmed us never to have been created? Are we to believe that our life lay groveling in murk and misery until the first day of creation dawned for us? All people, once born, must certainly wish to remain in life, so long as seductive pleasure detains them; but if one has never tasted the love of life or been numbered among the living, how does it harm one not to have been created?”

“He saw that almost everything that necessity demands for subsistence had been already provided for mortals, and that their life was, so far as possible, established in security; he saw too that they possessed power, with wealth, honor, and glory, and took pride in the good reputation of their children; and yet he found that, notwithstanding this prosperity, all of them privately had hearts racked with anxiety which, contrary to their wish, tormented their lives without a pause, causing them to chafe and fret. Then he realized that the cause of the flaw was the vessel itself, which by its own flaw corrupted within it all things, even good things, that entered it from without. He became convinced of this, partly because he saw that the vessel was leaky and riddled, so that it could never possibly be filled, and partly because he observed that it contaminated with a foul flavor everything it had taken in.”
