nor, lastly, is it apparent on non-apparent, because the sign, being relative, must be apprehended along with that of which it is the sign, which is not here the case. It follows that nothing uncertain can be apprehended; for it is through signs that uncertain things are said to be apprehended.[*](This conclusion would debar us from all extension of knowledge beyond what is apparent here and now; whereas the dogmatists permit us from such facts to advance to what is not immediately evident, the realm of the unknown or as yet unascertained (ἄδηλον).).

Causes, too, they destroy in this way. A cause is something relative; for it is relative to what can be caused, namely, the effect. But things which are relative are merely objects of thought and have no substantial existence.

Therefore a cause can only be an object of thought; inasmuch as, if it be a cause, it must bring with it that of which it is said to be the cause, otherwise it will not be a cause. Just as a father, in the absence of that in relation to which he is called father, will not be a father, so too with a cause. But that in relation to which the cause is thought of, namely the effect, is not present; for there is no coming into being or passing away or any other process: therefore there is no such thing as cause. Furthermore, if there is a cause, either bodies are the cause of bodies, or things incorporeal of things incorporeal; but neither is the case; therefore there is no such thing as cause. Body in fact could not be the cause of body, inasmuch as both have the same nature. And if either is

V2_511
called a cause in so far as it is a body, the other, being a body, will become a cause.

But if both be alike causes, there will be nothing to be acted upon Nor can an incorporeal thing be the cause of an incorporeal thing, for the same reason. And a thing incorporeal cannot be the cause of a body, since nothing incorporeal creates anything corporeal. And, lastly, a body cannot be the cause of anything incorporeal, because what is produced must be of the material operated upon; but if it is not operated upon because it is incorporeal, it cannot be produced by anything whatever. Therefore there is no such thing as a cause. A corollary to this is their statement that the first principles of the universe have no real existence; for in that case something must have been there to create and act.

Furthermore there is no motion; for that which moves moves either in the place where it is or in a place where it is not. But it cannot move in the place where it is, still less in any place where it is not. Therefore there is no such thing as motion.

They used also to deny the possibility of learning. If anything is taught, they say, either the existent is taught through its existence or the non-existent through its non-existence. But the existent is not taught through its existence, for the nature of existing things is apparent to and recognized by all; nor is the non-existent taught through the nonexistent, for with the non-existent nothing is ever done, so that it cannot be taught to anyone.

Nor, say they, is there any coming into being. For that which is does not come into being, since it is; nor yet that which is not, for it has no substantial

V2_513
existence, and that which is neither substantial nor existent cannot have had the chance of coming into being either.

There is nothing good or bad by nature, for if there is anything good or bad by nature, it must be good or bad for all persons alike, just as snow is cold to all. But there is no good or bad which is such to all persons in common; therefore there is no such thing as good or bad by nature. For either all that is thought good by anyone whatever must be called good, or not all. Certainly all cannot be so called; since one and the same thing is thought good by one person and bad by another; for instance, Epicurus thought pleasure good and Antisthenes thought it bad; thus on our supposition it will follow that the same thing is both good and bad. But if we say that not all that anyone thinks good is good, we shall have to judge the different opinions; and this is impossible because of the equal validity of opposing arguments. Therefore the good by nature is unknowable.

The whole of their mode of inference can be gathered from their extant treatises. Pyrrho himself, indeed, left no writings, but his associates Timon, Aenesidemus, Numenius and Nausiphanes did; and others as well.

The dogmatists answer them by declaring that the Sceptics themselves do apprehend and dogmatize; for when they are thought to be refuting their hardest they do apprehend, for at the very same time they are asseverating and dogmatizing. Thus even when they declare that they determine nothing, and that to every argument there is an opposite argument, they are actually determining these very points and dogmatizing.

The others reply, We

V2_515
confess to human weaknesses; for we recognize that it is day and that we are alive, and many other apparent facts in life; but with regard to the things about which our opponents argue so positively, claiming to have definitely apprehended them, we suspend our judgement because they are not certain, and confine knowledge to our impressions.[*](i.e. all we know is that we feel. Cf. supra, ii.§ 92.) For we admit that we see, and we recognize that we think this or that, but how we see or how we think we know not. And we say in conversation that a certain thing appears white, but we are not positive that it really is white. As to our We determine nothing and the like,[*](§ 74.) we use the expressions in an undogmatic sense,

for they are not like the assertion that the world is spherical. Indeed the latter statement is not certain, but the others are mere admissions. Thus in saying We determine nothing, we are not determining even that.

Again, the dogmatic philosophers maintain that the Sceptics do away with life itself, in that they reject all that life consists in. The others say this is false, for they do not deny that we see; they only say that they do not know how we see. We admit the apparent fact, say they, without admitting that it really is what it appears to be. We also perceive that fire burns; as to whether it is its nature to burn, we suspend our judgement.

We see that a man moves, and that he perishes; how it happens we do not know. We merely object to accepting the unknown substance behind phenomena. When we say a picture has projections, we are describing what is apparent; but if we say that it has no projections, we are then speaking, not of what is apparent, but of something else. This is

V2_517
what makes Timon say in his Python that he has not gone outside what is customary. And again in the Conceits he says[*](Fr. 69 D.):
But the apparent is omnipotent wherever it goes;
and in his work On the Senses, I do not lay it down that honey is sweet, but I admit that it appears to be so.

Aenesidemus too in the first book of his Pyrrhonean Discourses says that Pyrrho determines nothing dogmatically, because of the possibility of contradiction, but guides himself by apparent facts. Aenesidemus says the same in his works Against Wisdom and On Inquiry. Furthermore Zeuxis, the friend of Aenesidemus, in his work On Two-sided Arguments, Antiochus of Laodicea, and Apellas in his Agrippa all hold to phenomena alone. Therefore the apparent is the Sceptic’s criterion, as indeed Aenesidemus says; and so does Epicurus. Democritus, however, denied that any apparent fact could be a criterion, indeed he denied the very existence of the apparent.

Against this criterion of appearances the dogmatic philosophers urge that, when the same appearances produce in us different impressions, e.g. a round or square tower, the Sceptic, unless he gives the preference to one or other, will be unable to take any course; if on the other hand, say they, he follows either view, he is then no longer allowing equal value to all apparent facts. The Sceptics reply that, when different impressions are produced, they must both be said to appear[*](i.e. the one has as much right to be called an appearance as the other.); for things which are apparent are so called because they appear. The end to be realized they hold to be suspension of judgement, which brings with it

V2_519
tranquillity like its shadow: so Timon and Aenesidemus declare.

For in matters which are for us to decide we shall neither choose this nor shrink from that; and things which are not for us to decide but happen of necessity, such as hunger, thirst and pain, we cannot escape,[*](Τὰ δʼ ὅσα περὶ ἡμᾶς οὐκ ἔστιν, ἀλλὰ κατʼ ἀνάγκην, οὐ δυνάμεθα φεύγειν. This is explained by Sext. Emp. Pyrrh. Hyp. i. 29 ὀχλεῖς θαίφαμεν (sc. τὸν σκεπτικὸν) ὑπὸ τῶν κατηναγκα σμένων· For we admit that we feel cold, that we are thirsty, etc.) for they are not to be removed by force of reason. And when the dogmatists argue that he may thus live in such a frame of mind that he would not shrink from killing and eating his own father if ordered to do so, the Sceptic replies that he will be able so to live as to suspend his judgement in cases where it is a question of arriving at the truth, but not in matters of life and the taking of precautions. Accordingly we may choose a thing or shrink from a thing by habit and may observe rules and customs. According to some authorities the end proposed by the Sceptics is insensibility; according to others, gentleness.[*](i.e. a calm, the opposite of an excitable, temperament: cf. Plato, Lys. 211 e πρᾁως ἔχω.)

Timon, says our[*](Ὁ παρʼ ἡμῶν. Reiske took this to mean my fellowcitizen, ὁ τῆς ἡμετέρας πόλεως. Hence Usener inferred that Nicias of Nicaea was the author here used by D. L.; but nothing that we know of this Nicias tends to confirm such a conjecture. In favour of the translation adopted by most scholars it may be urged that Strabo calls the Stoics οἱ ἡμέτεροι, just as Cicero calls the Academics nostri. Even if we accept this meaning, a Sceptic like myself, a further subtlety arises. Is D. L. here speaking in his own person or has he merely transcribed ὁ παρʼ ἡμῶν from a monograph of a Sceptic? Something may be urged on either side; for reasons given in Introd. p. xiii, the former conjecture seems somewhat more probable.) Apollonides of Nicaea in the first book of his commentaries On the Silli, which he dedicated to Tiberius Caesar, was the son of Timarchus and a native of Phlius. Losing his parents when young, he became a stage-dancer, but later

V2_521
took a dislike to that pursuit and went abroad to Megara to stay with Stilpo; then after some time he returned home and married. After that he went to Pyrrho at Elis with his wife, and lived there until his children were born; the elder of these he called Xanthus, taught him medicine, and made him his heir.

This son was a man of high repute, as we learn from Sotion in his eleventh book. Timon, however, found himself without means of support and sailed to the Hellespont and Propontis. Living now at Chalcedon as a sophist, he increased his reputation still further and, having made his fortune, went to Athens, where he lived until his death, except for a short period which he spent at Thebes. He was known to King Antigonus and to Ptolemy Philadelphus, as his own iambics[*](Possibly the proem of the Silli.) testify.

He was, according to Antigonus, fond of wine, and in the time that he could spare from philosophy he used to write poems. These included epics, tragedies, satyric dramas, thirty comedies and sixty tragedies, besides silli (lampoons) and obscene poems.

There are also reputed works of his extending to twenty thousand verses which are mentioned by Antigonus of Carystus, who also wrote his life. There are three silli in which, from his point of view as a Sceptic, he abuses every one and lampoons the dogmatic philosophers, using the form of parody. In the first he speaks in the first person throughout, the second and third are in the form of dialogues; for he represents himself as questioning Xenophanes of Colophon about each philosopher in turn, while Xenophanes answers him; in the second he speaks of the more ancient philosophers, in the third of the

V2_523
later, which is why some have entitled it the Epilogue.

The first deals with the same subjects, except that the poem is a monologue. It begins as follows[*](Fr. 1 D.):

Ye sophists, ye inquisitives, come ! follow !

He died at the age of nearly ninety, so we learn from Antigonus and from Sotion in his eleventh book. I have heard that he had only one eye; indeed he used to call himself a Cyclops. There was another Timon, the misanthrope.[*](Diels regards the passage from καὶ ἔπη,§ 110, down to Τίμων ὁ μισάνθρωπος,§ 112, as an insertion, disturbing the symmetry of the materials derived from Antigonus of Carystus.)

Now this philosopher, according to Antigonus, was very fond of gardens and preferred to mind his own affairs. At all events there is a story that Hieronymus the Peripatetic said of him, Just as with the Scythians those who are in flight shoot as well as those who pursue, so, among philosophers, some catch their disciples by pursuing them, some by fleeing from them, as for instance Timon.

He was quick to perceive anything and to turn up his nose in scorn; he was fond of writing and at all times good at sketching plots for poets and collaborating in dramas. He used to give the dramatists Alexander and Homer materials for their tragedies.[*](i.e. he collaborated with these two tragic poets, Alexander the Aetolian and Homer of Byzantinum, partly by furnishing them with plots, partly by handing over scenes from unpublished plays of his own, or other similar material.) When disturbed by maidservants and dogs, he would stop writing, his earnest desire being to maintain tranquillity. Aratus is said to have asked him how he could obtain a trustworthy text of Homer, to which he replied, You can, if you get hold of the ancient copies, and not the corrected copies of our day. He used to let his own poems lie about, sometimes

V2_525
half eaten away.

Hence, when he came to read parts of them to Zopyrus the orator, he would turn over the pages and recite whatever came handy; then, when he was half through, he would discover the piece which he had been looking for in vain, so careless was he.[*](Similar carelessness is recorded of Lamartine.) Furthermore, he was so easy-going that he would readily go without his dinner. They say that once, when he saw Arcesilaus passing through the knaves-market, he said, What business have you to come here, where we are all free men? He was constantly in the habit of quoting, to those who would admit the evidence of the senses when confirmed by the judgement of the mind, the line—

Birds of a feather flock together.[*](Usually explained, after Diogenianus, of two notorious thieves, Attagas the Thessalian and Numenius the Corinthian. There may, however, be a sly hit at Pyrrho’s disciple Numenius (supra, § 102). Or merely the birds partridge and woodcock may be meant, not any Mr. Partridge and Mr. Woodcock.)
Jesting in this fashion was habitual with him. When a man marvelled at everything, he said, Why do you not marvel that we three have but four eyes between us? for in fact he himself had only one eye, as also had his disciple Dioscurides, while the man whom he addressed was normal.

Asked once by Arcesilaus why he had come there from Thebes, he replied, Why, to laugh when I have you all in full view ! Yet, while attacking Arcesilaus in his Silli, he has praised him in his work entitled the Funeral Banquet of Arcesilaus.

According to Menodotus he left no successor, but his school lapsed until Ptolemy of Cyrene re-established it. Hippobotus and Sotion, however, say that he had as pupils Dioscurides of Cyprus, Nicolochus of Rhodes, Euphranor of Seleucia, and Praÿlus of the

V2_527
Troad.[*](This is probably the same person as is referred to by Clem. Alex. Strom. iv. 56, where the text reads Παῦλος ὁ Λακύδου γνώριμος. His heroic end was also extolled (Clement says) by Timotheus of Pergamum. See Wilamowitz, Phil. Unters. iv. p. 107.) The latter, as we learn from the history of Phylarchus, was a man of such unflinching courage that, although unjustly accused, he patiently suffered a traitor’s death, without so much as deigning to speak one word to his fellow-citizens.

Euphranor had as pupil Eubulus of Alexandria; Eubulus taught Ptolemy, and he again Sarpedon and Heraclides; Heraclides again taught Aenesidemus of Cnossus, the compiler of eight books of Pyrrhonean discourses; the latter was the instructor of Zeuxippus his fellow-citizen, he of Zeuxis of the angular foot (γωνιόπους, Cruickshank), he again of Antiochus of Laodicea on the Lycus, who had as pupils Menodotus of Nicomedia, an empiric physician, and Theiodas of Laodicea; Menodotus was the instructor of Herodotus of Tarsus, son of Arieus, and Herodotus taught Sextus Empiricus, who wrote ten books on Scepticism, and other fine works. Sextus taught Saturninus called Cythenas,[*](Possibly κυδαθηναιεύς, i.e. a member of the well-known Attic deme, into which even Italians with such names as Saturninus might penetrate under the cosmopolitan empire of the Severi.) another empiricist.
