Leucippus was born at Elea, but some say at Abdera and others at Miletus. He was a pupil of Zeno. His views were these. The sum of things is unlimited, and they all change into one another. The All includes the empty as well as the full. The worlds are formed when atoms fall into the void and are entangled with one another ; and from their motion as they increase in bulk arises the substance of the stars. The sun revolves in a larger circle round the moon. The earth rides steadily, being whirled about the centre ; its shape is like that of a drum. Leucippus was the first to set up atoms as first principles. Such is a general summary of his views ; on particular points they are as follows.
9.6.31He declares the All to be unlimited, as already stated ; but of the All part is full and part empty, note and these he calls elements. Out of them arise the worlds unlimited in number and into them they are dissolved. This is how the worlds are formed. In a given section many atoms of all manner of shapes are carried from the unlimited into the vast empty space. These collect together and form a single vortex, in which they jostle against each other and, circling round in every possible way, separate off, by like atoms joining like. And, the atoms being so numerous that they can no longer revolve in equilibrium, the light ones pass into the empty space outside, as if they were being winnowed ; the remainder keep together and, becoming entangled, go on their circuit together, and form a primary spherical system.
9.6.32 This parts off like a shell, enclosing within it atoms of all kinds ; and, as these are whirled round by virtue of the resistance of the centre, the enclosing shell becomes thinner, the adjacent atoms continually combining when they touch the vortex.In this way the earth is formed by portions brought to the centre coalescing. And again, even the outer shell grows larger by the influx of atoms from outside, and, as it is carried round in the vortex, adds to itself whatever atoms it touches. And of these some portions are locked together and form a mass, at first damp and miry, but, when they have dried and revolve with the universal vortex, they afterwards take fire and form the substance of the stars.
9.6.33The orbit of the sun is the outermost, that of the moon nearest to the earth; the orbits of the other heavenly bodies lie between these two. All the stars are set on fire by the speed of their motion; the burning of the sun is also helped by the stars; the moon is only slightly kindled. The sun and the moon are eclipsed [when ..., but the obliquity of the zodiacal circle is due note] to the inclination of the earth to the south ; the regions of the north are always shrouded in mist, and are extremely cold and frozen. Eclipses of the sun are rare ; eclipses of the moon constantly occur, and this because their orbits are unequal. As the world is born, so, too, it grows, decays and perishes, in virtue of some necessity, the nature of which he does [not] specify.
Democritus was the son of Hegesistratus, though some say of Athenocritus, and others again of Damasippus. He was a native of Abdera or, according to some, of Miletus. He was a pupil of certain Magians and Chaldaeans. For when King Xerxes was entertained by the father of Democritus he left men in charge, as, in fact, is stated by Herodotus note; and from these men, while still a boy, he learned theology and astronomy. Afterwards he met Leucippus and, according to some, Anaxagoras, being forty years younger than the latter. But Favorinus in his Miscellaneous History tells us that Democritus, speaking of Anaxagoras, declared that his views on the sun and the moon were not original but of great antiquity, and that he had simply stolen them. Democritus also pulled to pieces the views of Anaxagoras on cosmogony and on mind,
9.7.35 having a spite against him, because Anbaxagoras did not take to him. If this be so, how could he have been his pupil, as some suggest ?According to Demetrius in his book on Men of the Same Name and Antisthenes in his Successions of Philosophers, he travelled into Egypt to learn geometry from the priests, and he also went into Persia to visit the Chaldaeans as well as to the Red Sea. Some say that he associated with the Gymnosophists in India and went to Aethiopia. Also that, being the third son, he divided the family property. Most authorities will have it that he chose the smaller portion, which was in money, because he had need of this to pay the cost of travel; besides, his brothers were crafty enough to foresee that this would be his choice.
9.7.36 Demetrius estimates his share at over 100 talents, the whole of which he spent. His industry, says the same author, was so great that he cut off a little room in the garden round the house and shut himself up there. One day his father brought an ox to sacrifice and tied it there, and he was not aware of it for a considerable time, until his father roused him to attend the sacrifice and told him about the ox. Demetrius goes on : "It would seem that he also went to Athens and was not anxious to be recognized, because he despised fame, and that while he knew of Socrates, he was not known to Socrates, his words being, `I came to Athens and no one knew me.'"| Diogenes Laertius, Lives of Eminent Philosophers (English) (XML Header) [word count] [lemma count] [Diog.
