From the midst of the very fountain of pleasure, something of bitterness arises to vex us in the flower of enjoyment.
LucretiusViolence and injury enclose in their net all that do such things, and generally return upon him who began.
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.
