If the Rivals be the work of Plato, says Thrasylus, Democritus will be the unnamed character, different from Oenopides and Anaxagoras, who makes his appearance when conversation is going on with Socrates about philosophy, and to whom Socrates says that the philosopher is like the all-round athlete.[*](Rivals, 132 a-c.) And truly Democritus was versed in every department of philosophy, for he had trained himself both in physics and in ethics, nay more, in mathematics and the routine subjects of education, and he was quite an expert in the arts. From him we have the saying, Speech is the shadow of action. Demetrius of Phalerum in his Defence of Socrates affirms that he did not even visit Athens. This is to make the larger claim, namely, that he thought that great city beneath his notice, because he did not care to win fame from a place, but preferred himself to make a place famous.

His character can also be seen from his writings. He would seem, says Thrasylus, to have been an admirer of the Pythagoreans. Moreover, he mentions Pythagoras himself, praising him in a work of his own entitled Pythagoras.[*]( § 46.) He seems to have taken all his ideas from him and, if chronology did not stand in the way, he might have been thought his pupil. Glaucus of Rhegium certainly says that

V2_449
he was taught by one of the Pythagoreans, and Glaucus was his contemporary. Apollodorus of Cyzicus, again, will have it that he lived with Philolaus.

He would train himself, says Antisthenes, by a variety of means to test his sense-impressions by going at times into solitude and frequenting tombs.

The same authority states that, when he returned from his travels, he was reduced to a humble mode of life because he had exhausted his means; and, because of his poverty, he was supported by his brother Damasus. But his reputation rose owing to his having foretold certain future events; and after that the public deemed him worthy of the honour paid to a god.[*](ὡς δὲ προειπών . . . ἠξιώθη. This sentence in oratio recta, interrupting the extract from Antisthenes, finds its counterpart in the stories attributing to Democritus the power of forecasting the weather or the seasons, on the strength of his scientific attainments. Cf.. Pliny, N.H. xviii. 273, 341, and Clem. Alex. Strom. vii. 32.) There was a law, says Antisthenes, that no one who had squandered his patrimony should be buried in his native city. Democritus, understanding this, and fearing lest he should be at the mercy of any envious or unscrupulous prosecutors, read aloud to the people his treatise, the Great Diacosmos, the best of all his works; and then he was rewarded with 500 talents; and, more than that, with bronze statues as well; and when he died, he received a public funeral after a lifetime of more than a century.

Demetrius, however, says that it was not Democritus himself but his relatives who read the Great Diacosmos, and that the sum awarded was 100 talents only; with this account Hippobotus agrees.

Aristoxenus in his Historical Notes affirms that Plato wished to burn all the writings of Democritus that he could collect, but that Amyclas and Clinias

V2_451
the Pythagoreans prevented him, saying that there was no advantage in doing so, for already the books were widely circulated. And there is clear evidence for this in the fact that Plato, who mentions almost all the early philosophers, never once alludes to Democritus, not even where it would be necessary to controvert him, obviously because he knew that he would have to match himself against the prince of philosophers, for whom, to be sure, Timon[*](Fr. 46 D.) has this meed of praise[*](Cf.Il. i. 263, iv. 341.):
Such is the wise Democritus, the guardian of discourse, keen-witted disputant, among the best I ever read.

As regards chronology, he was, as he says himself in the Lesser Diacosmos, a young man when Anaxagoras was old, being forty years his junior. He says that the Lesser Diacosmos was compiled 730 years after the capture of Troy. According to Apollodorus in his Chronology he would thus have been born in the 80th Olympiad,[*](460-457 b.c.) but according to Thrasylus in his pamphlet entitled Prolegomena to the Reading of the works of Democritus, in the third year of the 77th Olympiad,[*](470-469 b.c.) which makes him, adds Thrasylus, one year older than Socrates. He would then be a contemporary of Archelaus, the pupil of Anaxagoras, and of the school of Oenopides; indeed he mentions Oenopides.

Again, he alludes to the doctrine of the One held by Parmenides and Zeno, they being evidently the persons most talked about in his day; he also mentions Protagoras of Abdera, who, it is admitted, was a contemporary of Socrates.

Athenodorus in the eighth book of his Walks relates that, when Hippocrates came to see him, he ordered

V2_453
milk to be brought, and, having inspected it, pronounced it to be the milk of a black she-goat which had produced her first kid; which made Hippocrates marvel at the accuracy of his observation. Moreover, Hippocrates being accompanied by a maidservant, on the first day Democritus greeted her with Good morning, maiden, but the next day with Good morning, woman, As a matter of fact the girl had been seduced in the night.

Of the death of Democritus the account given by Hermippus is as follows. When he was now very old and near his end, his sister was vexed that he seemed likely to die during the festival of Thesmophoria and she would be prevented from paying the fitting worship to the goddess. He bade her be of good cheer and ordered hot loaves to be brought to him every day. By applying these to his nostrils he contrived to outlive the festival; and as soon as the three festival days were passed he let his life go from him without pain, having then, according to Hipparchus, attained his one hundred and ninth year.

In my Pammetros I have a piece on him as follows[*](Anth. Pal. vii. 57.):

Pray who was so wise, who wrought so vast a work as the omniscient Democritus achieved? When Death was near, for three days he kept him in his house and regaled him with the steam of hot loaves.
Such was the life of our philosopher.

His opinions are these. The first principles of the universe are atoms and empty space; everything else is merely thought to exist. The worlds are unlimited; they come into being and perish. Nothing can come into being from that which is not

V2_455
nor pass away into that which is not. Further, the atoms are unlimited in size and number, and they are borne along in the whole universe in a vortex, and therby generate all composite things—fire, water, air, earth; for even these are conglomerations of given atoms. And it is because of their solidity that these atoms are impassive and unalterable. The sun and the moon have been composed of such smooth and spherical masses [i.e. atoms], and so also the soul, which is identical with reason. We see by virtue of the impact of images upon our eyes.

All things happen by virtue of necessity, the vortex being the cause of the creation of all things, and this he calls necessity. The end of action is tranquillity, which is not identical with pleasure, as some by a false interpretation have understood, but a state in which the soul continues calm and strong, undisturbed by any fear or superstition or any other emotion. This he calls well-being and many other names. The qualities of things exist merely by convention; in nature there is nothing but atoms and void space. These, then, are his opinions.

Of his works Thrasylus has made an ordered catalogue, arranging them in fours, as he also arranged Plato’s works.

The ethical works are the following:

  • I. Pythagoras.
  • Of the Disposition of the Wise Man.
  • Of those in Hades.
  • Tritogeneia (so called because three things, on which all mortal life depends, come from her).
  • II. Of Manly Excellence, or Of Virtue. Amalthea’s Horn (the Horn of Plenty).
    V2_457
  • Of Tranquillity.
  • Ethical Commentaries: the work on Wellbeing is not to be found.
  • So much for the ethical works.

    The physical works are these:

  • III. The Great Diacosmos (which the school of Theophrastus attribute to Leucippus).
  • The Lesser Diacosmos.
  • Description of the World.
  • On the Planets.
  • IV. Of Nature, one book.
  • Of the Nature of Man, or Of Flesh, a second book on Nature.
  • Of Reason.
  • Of the Senses (some editors combine these two under the title Of the Soul).
  • V. Of Flavours.
  • Of Colours.

  • Of the Different Shapes (of Atoms).
  • Of Changes of Shape.
  • VI. Confirmations (summaries of the aforesaid works).

The title Ἐκπετάσματα may therefore mean Projection of an armillary sphere on a plane.) (Projections).

  • The Great Year, or Astronomy, Calendar.
  • Contention of the Water-clock [and the Heaven].
  • IX. Description of the Heaven.

  • Legal Causes and Effects.
  • Problems wrought by Hand.[*](χειρόκμητα is a correction of Salmasius based upon Pliny, N.H. xxiv. 160, and Vitruvius, ix. i. 14. The mss. give either χέρνιβα,finger-bowls, or χερνικά, the sense of which is not clear; they read ἢ before προβλήματα..)

    The other works which some attribute to Democritus

    V2_463
    are either compilations from his writings or admittedly not genuine. So much for the books that he wrote and their number.

    The name of Democritus has been borne by six persons: (1) our philosopher; (2) a contemporary of his, a musician of Chios; (3) a sculptor, mentioned by Antigonus; (4) an author who wrote on the temple at Ephesus and the state of Samothrace; (5) an epigrammatist whose style is lucid and ornate; (6) a native of Pergamum who made his mark by rhetorical speeches.

  • Protagoras, son of Artemon or, according to Apollodorus and Dinon in the fifth book of his History of Persia, of Maeandrius, was born at Abdera (so says Heraclides of Pontus in his treatise On Laws, and also that he made laws for Thurii) or, according to Eupolis in his Flatterers, at Teos; for the latter says:

    Inside we’ve got Protagoras of Teos.
    He and Prodicus of Ceos gave public readings for which fees were charged, and Plato in the Protagoras[*](316 a.) calls Prodicus deep-voiced. Protagoras studied under Democritus. The latter[*](Cf. Clem. Strom. vi. 32, and Suidas, s.v. Δημόκριτος.) was nicknamed Wisdom, according to Favorinus in his Miscellaneous History.

    Protagoras was the first to maintain that there are two sides to every question, opposed to each other, and he even argued in this fashion, being the first to do so. Furthermore he began a work thus: Man is the measure of all things, of things that are that they are, and of things that are not that they

    V2_465
    are not. He used to say that soul was nothing apart from the senses, as we learn from Plato in the Theaetetus,[*](152 a sq.) and that everything is true. In another work he began thus: As to the gods, I have no means of knowing either that they exist or that they do not exist. For many are the obstacles that impede knowledge, both the obscurity of the question and the shortness of human life.

    For this introduction to his book the Athenians expelled him; and they burnt his works in the market-place, after sending round a herald to collect them from all who had copies in their possession.

    He was the first to exact a fee of a hundred minae and the first to distinguish the tenses of verbs, to emphasize the importance of seizing the right moment, to institute contests in debating, and to teach rival pleaders the tricks of their trade. Furthermore, in his dialectic he neglected the meaning in favour of verbal quibbling, and he was the father of the whole tribe of eristical disputants now so much in evidence; insomuch that Timon[*](Fr. 47 D.) too speaks of him as[*](Cf.Il. xv. 679.)

      Protagoras, all mankind’s epitome,
    1. Cunning, I trow, to war with words.

    He too first introduced the method of discussion which is called Socratic. Again, as we learn from Plato in the Euthydemus,[*](286 c.) he was the first to use in discussion the argument of Antisthenes which strives to prove that contradiction is impossible, and the first to point out how to attack and refute any proposition laid down: so Artemidorus the dialectician in his treatise In Reply to Chrysippus. He too invented the shoulder-pad on which porters carry their burdens, so we are told by Aristotle in his treatise On Education; for he himself had been a porter,

    V2_467
    says Epicurus somewhere.[*](Sc. in an epistle, Περὶ ἐπιτηδευμάτων, cf. Athen. viii. 354 c.) This was how he was taken up by Democritus, who saw how skilfully his bundles of wood were tied. He was the first to mark off the parts of discourse into four, namely, wish, question, answer, command[*](This answers roughly to the optative, the indicative, and the imperative.);

    others divide into seven parts, narration, question, answer, command, rehearsal, wish, summoning; these he called the basic forms of speech. Alcidamas made discourse fourfold, affirmation, negation, question, address.

    The first of his books he read in public was that On the Gods, the introduction to which we quoted above; he read it at Athens in Euripides’ house, or, as some say, in Megaclides’; others again make the place the Lyceum and the reader his disciple Archagoras, Theodotus’s son, who gave him the benefit of his voice. His accuser was Pythodorus, son of Polyzelus, one of the four hundred; Aristotle, however, says it was Euathlus.

    The works of his which survive are these:

  • * * The Art of Controversy.
  • Of Wrestling.
  • On Mathematics.
  • Of the State.
  • Of Ambition.
  • Of Virtues.
  • Of the Ancient Order of Things.
  • On the Dwellers in Hades.
  • Of the Misdeeds of Mankind.
  • A Book of Precepts.
  • Of Forensic Speech for a Fee, two books of opposing arguments.
  • This is the list of his works.[*](That the list is defective is evident from the fact that the two works by which Protagoras is best known (supra, §§ 51, 54) are not here named.) Moreover there is a dialogue which Plato wrote upon him.

    V2_469

    Philochorus says that, when he was on a voyage to Sicily, his ship went down, and that Euripides hints at this in his Ixion.

  • According to some his death occurred, when he was on a journey, at nearly ninety years of age, though Apollodorus makes his age seventy, assigns forty years for his career as a sophist, and puts his floruit in the 84th Olympiad.[*](444-441 b.c.)

    There is an epigram of my own on him as follows[*](Anth. Pal. vii. 130.):

      Protagoras, I hear it told of thee
    1. Thou died’st in eld when Athens thou didst flee;
    2. Cecrops’ town chose to banish thee; but though
    3. Thou ’scap’dst Athene, not so Hell below.

    The story is told that once, when he asked Euathlus his disciple for his fee, the latter replied, But I have not won a case yet. Nay, said Protagoras, if I win this case against you I must have the fee, for winning it; if you win, I must have it, because you win it.

    There was another Protagoras, an astronomer, for whom Euphorion wrote a dirge; and a third who was a Stoic philosopher.
