Dêmocritus of Abdêra was in his prime about 420 B.C.
A large body of written work was produced at Abdera, during and after Democritus time. Thrasyllus, Roman scholar of the first century A.D., using the work of Alexandrian scholars, arranged these works in tetralogies, according to their subject-matter. Ethics (Tetralogies I and II); Natural Science (III to VI); Mathematics (VII to IX); Music (X and XI); and Technical Works (XII and XIII). There were also a group of treatises under the title Causes; a group of monographs on various subjects, the genuineness of which is suspect; a large number of Maxims; and a group of forged writings on magic.

14a. 'Contest according to the Water-Clock' (?)
14b. 'Description of the Heavens.'
14c. 'Description of the Earth.'
15. 'Voyage round the World.' (Agathêmerus: After Anaximander, descriptions of a Voyage Round the World were written by Hecataeus, Hellanicus, and Damastes of Sigeion copying for the most part Hellanicus. Democritus and Eudoxus followed, and some others. The ancients described the world as round, with Greece in the centre, and Delphi the centre of Greece. But Democritus, a man of wide experience, was the first to describe it as rectangular, the length half the width. Dicaearchus the Peripatetic concurred).
15a. 'Description of the Pole.'
15b. 'Description of Rays.'
tetralogies X and XI: Music
16c. (Title): 'On Rhythm and Harmony'.

20a. (Title): 'On Homer, or a Correct Diction and Vocabulary.'
21. Homer, having been gifted with a divine nature, built an ordered structure of manifold verse.
22. The eagle has black bones.
23. (Scholiast on Homer: The Trojan herald speaking to the Greeks says of Paris 'Would that he had perished first!' ('Iliad,' VII. 390). Democritus thinks that he spoke this as an aside, because it would not be proper for him to say this in front of all the Greeks).
24. (Eustathius on Homer, Od., xv. 374: The loyal slave Eumaeus was so highly regarded by the ancients that they even provide him with a mother: Democritus says she was Poverty).
25. (Eustathius on Homer, Od., xii. 62: Some think that the Sun is Zeus, others, with Democritus, that the vapour on which the sun feeds is ambrosia).
25a. (Title): 'On Song.'
25b. (Title): 'On Phrases.'
26. (Proclus: Pythagoras and Epicurus agree with Cratylus, but Democritus and Aristotle agree with Hermogenes, the former that names arise by nature, the latter that they arise by chance. Pythagoras thought that the Soul gave the names, deriving them like images of reality from the mind. But Democritus thought that the proof of their chance origin was fourfold: (1) the calling of different things by the same name; (2) having several names for the same thing; (3) change of name; (4) lack of name.

30. Of the reasoning men, a few, raising their hands thither to what we Greeks call the Air nowadays, said: 'Zeus considers all things and he knows all and gives and takes away all and is King of all.'
33. Nature and instruction are similar; for instruction transforms the man, and in transforming, creates his nature.
34. Man is a universe in little (Microcosm).
gnômae 2
35. If any man listens to my opinions, here recorded, with intelligence, he will achieve many things worthy of a good man, and avoid doing many unworthy things.
36. = 187.

41. Refrain from crimes not through fear but through duty.
42. It is a great thing, when one is in adversity, to think of duty.
43. Repentance for shameful deeds is salvation in life.
44. = 225.
45. The wrongdoer is more unfortunate than the man wronged.
65. One should practise much-sense, not much-learning. 1
66. It is better to deliberate before action than to repent afterwards.
67. Believe not everything, but only what is approved: the former is foolish, the latter the act of a sensible man.
68. The worthy and the unworthy man (are to be known) not only by their actions, but also their wishes.
69. For all men, good and true are the same; but pleasant differs for different men.
70. Immoderate desire is the mark of a child, not a man.
71. Untimely pleasures produce unpleasantnesses.
72. Violent desire for one thing blinds the soul to all others.
73. Virtuous love consists in decorous desire for the beautiful.
74. Accept no pleasure unless it is beneficial.
75. It is better for fools to be ruled than to rule.
76. For the foolish, not reason but advantage is the teacher.
77. Fame and wealth without intelligence are dangerous possessions.
78. To make money is not without use, but if it comes from wrong-doing, nothing is worse.
79. It is a bad thing to imitate the bad, and not even to wish to imitate the good.
80. It is shameful to be so busy over the affairs of others that one knows nothing of one's own.
81. Constant delay means work undone.
82. The false and the seeming-good are those who do all in word, not in fact.
99. Life is not worth living for the man who has not even one good friend.
116. I came to Athens and no one knew me.
128. Straight-bored.
129. They think divine thoughts with their mind.
129a. Is leaned.
130. Circular bands.
13I. Untrodden (unevenly compounded).
132. Equilateral.
133. Sodden.
155a. (Aristotle: Democritus treats the sphere as a sort of angle when cutting it).
156. Naught exists just as much as Aught.
157. Learn thoroughly the art of statesmanship, which is the greatest, and pursue its toils, from which men win great and brilliant prizes.
158. Men thinking new thoughts with each day.
159. (Democritus said): If the body brought a suit against the soul, for all the pains it had endured throughout life, and the illtreatment, and I were to be the judge of the suit, I would gladly condemn the soul, in that it had partly ruined the body by its neglect and dissolved it with bouts of drunkenness, and partly destroyed it and torn it in pieces with its passion for pleasureas if, when a tool or a vessel were in a bad condition, I blamed the man who was using it carelessly.
160. (To live badly is) not to live badly, but to spend a long time dying.
161. (Scholiast on Apollonius Rhodius: Eclipses were called 'down-drawings' up to the time of Democritus, with reference to the ancient belief that sorceresses could draw down the sun and moon and so cause eclipses).
162. (Scholiast on Homer, Iliad, XIII. 137: Democritus uses the epic word for 'large boulder' for the cylinder).
167. An eddy, of all manner of forms, is separated off from the Whole.
168. (Simplicius: The Democriteans called the atoms 'nature' . . . For they said that these were) scattered about.
169. Do not try to understand everything, lest you become ignorant of everything.
170. Happiness, like unhappiness, is a property of the soul.
171. Happiness does not dwell in flocks of cattle or in gold. The soul is the dwelling-place of the (good and evil) genius.
172. Those same things from which we get good can also be for us a source of hurt, or else we can avoid the hurt. For instance, deep water is useful for many purposes, and yet again harmful; for there is danger of being drowned. A technique has therefore been invented: instruction in swimming.
173. For mankind, evil comes out of what is good, if one does not know how to guide and drive correctly. It is not right to place such things in the category of evil, but in that of good. It is possible also to use what is good for an evil end 1 if one wishes.
180. Education is an ornament for the prosperous, a refuge for the unfortunate.
181. The man who employs exhortation and persuasion will turn out to be a more effective guide to virtue than he who employs law and compulsion. For the man who is prevented by law from wrongdoing will probably do wrong in secret, whereas the man who is led towards duty by persuasion will probably not do anything untoward either secretly or openly. Therefore the man who acts rightly through understanding and knowledge becomes at the same time brave and upright.
182. Beautiful objects are wrought by study through effort, but ugly things are reaped automatically without toil. For
237. All bellicosity is foolish; for in studying the disadvantage of one's enemy, one loses sight of one's own advantage.
238. The man who strives against the stronger ends in disgrace.
239. Bad men, when they escape, do not keep the oaths which they make in time of stress.
240. Toils undertaken willingly make the endurance of those done unwillingly easier.
241. Continuous labour becomes easier through habit.
242. More men become good through practice than by nature.
243. All kinds of toil are pleasanter than rest, when men attain that for which they labour, or know that they will attain it. But whenever there is failure to attain, then labour is painful and hard.
244. Do not say or do what is base, even when you are alone. Learn to feel shame in your own eyes much more than before others.
245. The laws would not prevent each man from living according to his inclination, unless individuals harmed each other; for envy creates the beginning of strife.
246. Life in a foreign country teaches self-sufficiency; for bread and bed are the sweetest cures for hunger and fatigue.
247. To a wise man, the whole earth is open; for the native land of a good soul is the whole earth.
248. The law wishes to benefit men's life; and it is able to do so, when they themselves wish to receive benefit; for it shows to those who obey it their own particular virtue.
254. When base men enter upon office, the more unworthy they are, the more neglectful, and they are filled with folly and recklessness.
255. When the powerful prevail upon themselves to lend to the indigent, and help them, and benefit them, herein at last is pity, and an end to isolation, and friendship, and mutual aid, and harmony among the citizens; and other blessings such as no man could enumerate.
256. Justice is to do what should be done; injustice is to fail to do what should be done, and to put it aside.
257. With certain animals, the rule for killing them or not stands thus: any that do wrong and wish to do so may be killed with impunity, and it conduces to well-being to do so rather than not do so.
259. As has been laid down (by me) regarding beasts and reptiles which are inimical (to man), so I think one should do with regard to human beings: one should, according to ancestral law, kill an enemy of the State in every ordered society, unless a law forbids it. But there are prohibitions in every State: sacred law, treaties and oaths.
260. Anyone killing any brigand or pirate shall be exempt from penalty, whether he do it by his own hand, or by instigation, or by vote.
261. One must punish wrong-doers to the best of one's ability, and not neglect it. Such conduct is just and good, but the neglect of it is unjust and bad.
262. Those who do what is deserving of exile or imprisonment or other punishment must be condemned and not let off. Whoever contrary to the law acquits a man, judging according to profit or pleasure, does wrong, and this is bound to be on his conscience.
263. He has the greatest share of justice and virtue who awards the greatest offices (honours?) (to the most deserving).
264. One must not respect the opinion of other men more than one's own; nor must one be more ready to do wrong if no one will know than if all will know. One must respect one's own opinion most, and this must stand as the law of one's soul, preventing one from doing anything improper.
265. Men remember one's mistakes rather than one's successes. This is just; for as those who return a deposit do not deserve praise, whereas those who do not do so deserve blame and punishment, so with the official: he was elected not to make mistakes but to do things well.
266. There is no means under the present constitution by which magistrates can be prevented from wrong-doing, however good they may be. For it is not likely for anyone else
267. Rule belongs by nature to the stronger.
268. Fear engenders flattery, but it has no good will.
269. Courage is the beginning of action, but Fortune is the arbiter of the goal.
270. Use slaves as parts of the body: each to his own function.
271. A lover's reproach is dissolved by (? corrupt word).
272. The man who is fortunate in his choice of a son-in-law gains a son; the man unfortunate in his choice loses his daughter also.
273. A woman is far sharper than a man in malign thoughts.
274. An adornment for a woman is lack of garrulity. Paucity of adornment is also beautiful.
275. The rearing of children is full of pitfalls. Success is attended by strife and care, failure means grief beyond all others.
276. I do not think that one should have children. I observe in the acquisition of children many great risks and many griefs, whereas a harvest is rare, and even when it exists, it is thin and poor.
277. Whoever wants to have children should, in my opinion, choose them from the family of one of his friends. He will thus obtain a child such as he wishes, for he can select the kind he wants. And the one that seems fittest will be most likely to follow on his natural endowment. The difference is that in the latter way one can take one child out of many who is according to one's liking; but if one begets a child of one's own, the risks are many, for one is bound to accept him as he is.

96:1 Bird-days are those on which migrant birds appear; bird-winds are those which bring migrant birds.

99:1 Pun on ἀποπληξίη and πληγή.
99:2 Given in a collection called 'Maxims of Democratês'. But Stobaeus quotes as 'Maxims of Democritus many of the sayings here recorded; it is therefore thought that 'Democrates' is a corruption of 'Democritus', or perhaps a later attribution by Byzantine scholars who had discovered the existence of one Democrates of Aphidna in Attica, a writer on agriculture of the fourth century B.C.
