It was certainly not by design that the particles fell into order, they did not work out what they were going to do, but because many of them by many chances struck one another in the course of infinite time and encountered every possible form and movement, that they found at last the disposition they have, and that is how the universe was created.
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.
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.
Lucretius(On the temperature of water in wells) The reason why the water in wells becomes colder in summer is that the earth is then rarefied by the heat, and releases into the air all the heat-particles it happens to have. So, the more the earth is drained of heat, the colder becomes the moisture that is concealed in the ground. On the other hand, when all the earth condenses and contracts and congeals with the cold, then, of course, as it contracts, it squeezes out into the wells whatever heat it holds.
