Natural philosopher — Democritus (Abdera, c. 460 – c. 370 BC) was an ancient Greek philosopher, a pupil of Leucippus and the chief exponent of atomism. According to his doctrine, reality is made up of atoms, indivisible and eternal particles, which move in the void and whose combinations give rise to all bodies and phenomena. With this idea Democritus proposed a purely materialistic and mechanical explanation of nature, without recourse to divine intervention. Although a philosophical insight rather than an experimental theory, ancient atomism anticipated the modern atomic conception of matter by more than two millennia. His works have almost all been lost, and we know him chiefly through the testimony of other authors.
