Nothing can be created out of nothing.Roman readers were first exposed to the Epicurean school of thought by Lucretius. The 7,400-word poem De Rerum Natura, which is broken up into six untitled books, examines Epicurean physics using a wealth of poetic language and analogies. Lucretius describes several celestial and terrestrial phenomena as well as the atomism theory, the nature of the mind and soul, explanations of sensation and thinking, the development of the world and its manifestations.
