Anaximenes (588-524 a.C) admitted, in accordance with Cotrim (1995), that the origin of all the things is indetermined, but, opposed to attribute to it the occult character to it of element it are of the limits you observed of the sensible experience. With Kenny quotation (1998), although Anaximenes to agree that the last element could not be the fire nor the water, affirmed that he was from the air that everything more had been generated. In its steady state air is invisible, but, when it is moved and if it condenses, it becomes first wind, later cloud and to follow water, and, finally, the condensed water becomes mud rock. Presumably, rarefied air becomes fire, what complete the gamma of the elements. (KENNY, 1998, p.23) In accordance with Chtelet (1981) Anaxmeres defends that it exists, as origin of everything, a reality submitted to the judgment of the experience, despite in a indeterminate direction. This principle will be air, invisible and imponderable element, almost inobservvel e, however, observvel: air is the proper life, the vital force, the deity that ' ' anima' ' the world, that of that of the certification to the breath.
(CHTELET, 1981, p.28) ABDERA DEMOCRITUS? ' ' The man, one microcosmo' '. Democritus (460-370 a.C) is a thinking daily pay-socrico, that in accordance with Cotrim (1995), only possesss this heading due the tradition, therefore it was been born and died after Scrates. Democritus was pupil of Leucipo and, for Kenny (1998), in the antiquity, Leucipo and Democritus frequently are mentioned in set, and the atomism that became both celebrities was probably creation of Leucipo. The basic characteristic of the atomism of Democritus was of that the substance is not infinitely divisible, affirming that the things that form the reality are constituted of invisible and indivisible particles, called atoms, that it means not-divisible. For Kenny (1998), the argument that arrived at this conclusion seems to have been philosophical and not experimental.
