The modern atomic theory, which has undergone continuous refinement, began to flourish at the beginning of the 19th century with the work of the . The atomists of the time (Democritus being one of the leading atomists) believed there were two realities that made up the physical world: atoms and void. The Parmenidean position was "You say there is a void; therefore the void is not nothing; therefore there is not the void. He reasoned that . Though it is common knowledge in the modern world that matter and material things are all composed of fundamental particles, it was not the leading theory that explained or described existence before and during Democritus' time. Democritus' model of an atom was one of an inert solid that interacted mechanically with other atoms. Democritus that result from the use of Pythagoras' life as model for Demo-critus are discussed later in this chapter. Their speculation on atoms, taken from Leucippus, bears a passing and partial resemblance to the 19th-century understanding of atomic structure that has led some to regard Democritus as more of a scientist than other Greek philosophers; however, their ideas rested on very different bases.
