refute it. Epicurus was influenced by Democritus 

 and his doctrine of Atomism, excluding Teleology

 thing is to be explained in a purely mechanicaL

From Epicurus we take a long leap in time to 

 T. Lucretius Carus, the Roman poet, whose inquiry 

 into the origin and nature of living things, as we 

 have observed, revived the teachings of Emped- 

 ocles, of Democritus, and especially of Epicurus. 

 He connected with these many observations of his 

 own. The fact that he was an original observer of 

 Nature must be inferred from his considerable 

 knowledge of animals and plants. It is possible 

 that the observations treated in his great poem may 

 have been more precisely recorded in some of his 

 lost books. 



Lucretius (99-55) was the second poet of Evo^

 doctrines of Epicurus, and set them in a far more 

 favourable light, building up anew the mechanical
