Fear in sooth holds so in check all mortals, becasue thay see many operations go on in earth and heaven, the causes of which they can in no way understand, believing them therefore to be done by power divine. for these reasons when we shall have seen that nothing can be produced from nothing, we shall then more correctly ascertain that which we are seeking, both the elements out of which every thing can be produced and the manner in which every thing can be produced in which all things are done without the hands of the gods.
LucretiusFrom the heart of this fountain of delights wells up some bitter taste to choke them even amid the flowers.
LucretiusAt 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.
