At this stage you must admit that whatever is seen to be sentient is nevertheless composed of atoms that are insentient. The phenomena open to our observation so not contradict this conclusion or conflict with it. Rather they lead us by the hand and compel us to believe that the animate is born, as I maintain, of the insentient.
LucretiusGlobed from the atoms falling slow or swift I see the suns, I see the systems lift Their forms; and even the systems and the suns Shall go back slowly to the eternal drift.
LucretiusMany animals even now spring out of the soil, Coalescing from the rains and the heat of the sun. Small wonder, then, if more and bigger creatures, Full-formed, arose from the new young earth and sky. The breed, for instance, of the dappled birds Shucked off their eggshells in the springtime, as Crickets in summer will slip their slight cocoons All by themselves, and search for food and life. Earth gave you, then, the first of mortal kinds, For all the fields were soaked with warmth and moisture.
LucretiusWhat came from the earth returns back to the earth, and the spirit that was sent from heaven, again carried back, is received into the temple of heaven.
LucretiusForbear to spew out reason from your mind, but rather ponder everything with keen judgment; and if it seems true, own yourself vanquished, but, if it is false, gird up your loins to fight.
LucretiusI return to the newborn world, and the soft-soil fields, What their first birthing lifted to the shores Of light, and trusted to the wayward winds. First the Earth gave the shimmer of greenery And grasses to deck the hills; then over the meadows The flowering fields are bright with the color of springtime, And for all the trees that shoot into the air.
Lucretius
