Critias, the well-known reactionary politician, the chief of the Thirty Tyrants, is placed amongst the atheists on the strength of a passage in a satyric drama, Sisyphus. The drama is lost, but our authority quotes the objectionable passage in extenso; it is a piece of no less than forty lines. The passage argues that human life in its origins knew no social order, that might ruled supreme. Then men conceived the idea of making laws in [pg 045] order that right might rule instead of might. The result of this was, it is true, that wrong was not done openly; but it was done secretly instead. Then a wise man bethought himself of making men believe that there existed gods who saw and heard everything which men did, nay even knew their innermost thoughts. And, in order that men might stand in proper awe of the gods, he said that they lived in the sky, out of which comes that which makes men afraid, such as lightning and thunder, but also that which benefits them, sunshine and rain, and the stars, those fair ornaments by whose course men measure time. Thus he succeeded in bringing lawlessness to an end. It is expressly stated that it was all a cunning fraud: “by such talk he made his teaching most acceptable, veiling truth with false words.”

In antiquity it was disputed whether the drama Sisyphus was by Critias or Euripides; nowadays all agree in attributing it to Critias; nor does the style of the long fragment resemble that of Euripides. The question is, however, of no consequence in this connexion: whether the drama is by Critias or Euripides it is wrong to attribute to an author opinions which he has put into the mouth of a character in a drama. Moreover, Sisyphus was a satyric play, i.e. it belonged to a class of poetry the liberty of which was nearly as great as in comedy, and the speech was delivered by Sisyphus himself, who, according to the legend, is a type of the crafty criminal whose forte is to do evil and elude punishment. There is, in fact, nothing in that which we otherwise hear of Critias to suggest that he cherished [pg 046] free-thinking views. He was—or in his later years became—a fanatical adversary of the Attic democracy, and he was, when he held power, unscrupulous in his choice of the means with which he opposed it and the men who stood in the path of his reactionary policy; but in our earlier sources he is never accused of impiety in the theoretical sense. And yet there had been an excellent opportunity of bringing forward such an accusation; for in his youth Critias had been a companion of Socrates, and his later conduct was used as a proof that Socrates corrupted his surroundings. But it is always Critias's political crimes which are adduced in this connexion, not his irreligion. On the other hand, posterity looked upon him as the pure type of tyrant, and the label atheist therefore suggested itself on the slightest provocation.

But, even if the Sisyphus fragment cannot be used to characterise its author as an atheist, it is, nevertheless, of the greatest interest in this connexion, and therefore demands closer analysis.

The introductory idea, that mankind has evolved from an animal state into higher stages, is at variance with the earlier Greek conception, namely, that history begins with a golden age from which there is a continual decline. The theory of the fragment is expressed by a series of authors from the same and the immediately succeeding period. It occurs in Euripides; a later and otherwise little-known tragedian, Moschion, developed it in detail in a still extant fragment; Plato accepted it and made it the basis of his presentation of the origin of the State; Aristotle takes it for [pg 047] granted. Its source, too, has been demonstrated: it was presumably Democritus who first advanced it. Nevertheless the author of the fragment has hardly got it direct from Democritus, who at this time was little known at Athens, but from an intermediary. This intermediary is probably Protagoras, of whom it is said that he composed a treatise, The Original State, i.e. the primary state of mankind. Protagoras was a fellow-townsman of Democritus, and recorded by tradition as one of his direct disciples.

In another point also the fragment seems to betray the influence of Democritus. When it is said that the wise inventors of the gods made them dwell in the skies, because from the skies come those natural phenomena which frighten men, it is highly suggestive of Democritus's criticism of the divine explanation of thunder and lightning and the like. In this case also Protagoras may have been the intermediary. In his work on the gods he had every opportunity of discussing the question in detail. But here we have the theory of Democritus combined with that of Prodicus in that it is maintained that from the skies come also those things that benefit men, and that they are on this account also a suitable dwelling-place for the gods. It is obvious that the author of the fragment (or his source) was versed in the most modern wisdom.

All this erudition, however, is made to serve a certain tendency: the well-known tendency to represent religion as a political invention having as its object the policing of society. It is a theory which in antiquity—to its honour be it said—is but [pg 048] of rare occurrence. There is a vague indication of it in Euripides, a more definite one in Aristotle, and an elaborate application of it in Polybius; and that is in reality all. (That many people in more enlightened ages upheld religion as a means of keeping the masses in check, is a different matter.) However, it is an interesting fact that the Critias fragment is not only the first evidence of the existence of the theory known to us, but also presumably the earliest and probably the best known to later antiquity. Otherwise we should not find reference for the theory made to a fragment of a farce, but to a quotation from a philosopher.

This might lead us to conclude that the theory was Critias's own invention, though, of course, it would not follow that he himself adhered to it. But it is more probable that it was a ready-made modern theory which Critias put into the mouth of Sisyphus. Not only does the whole character of the fragment and its scene of action favour this supposition, but there is also another factor which corroborates it.

In the Gorgias Plato makes one of the characters, Callicles—a man of whom we otherwise know nothing—profess a doctrine which up to a certain point is almost identical with that of the fragment. According to Callicles, the natural state (and the right state; on this point he is at variance with the fragment) is that right belongs to the strong. This state has been corrupted by legislation; the laws are inventions of the weak, who are also the majority, and their aim is to hinder the encroachment of the strong. If this theory is carried to its conclusion, [pg 049] it is obvious that religion must be added to the laws; if the former is not also regarded as an invention for the policing of society, the whole theory is upset. Now in the Gorgias the question as to the attitude of the gods towards the problem of what is right and what is wrong is carefully avoided in the discussion. Not till the close of the dialogue, where Plato substitutes myth for scientific research, does he draw the conclusion in respect of religion. He does this in a positive form, as a consequence of his point of view: after death the gods reward the just and punish the unjust; but he expressly assumes that Callicles will regard it all as an old wives' tale.

In Callicles an attempt has been made to see a pseudonym for Critias. That is certainly wrong. Critias was a kinsman of Plato, is introduced by name in several dialogues, nay, one dialogue even bears his name, and he is everywhere treated with respect and sympathy. Nowadays, therefore, it is generally acknowledged that Callicles is a real person, merely unknown to us as such. However that may be, Plato would never have let a leading character in one of his longer dialogues advance (and Socrates refute) a view which had no better authority than a passage in a satyric drama. On the other hand, there is, as shown above, difficulty in supposing that the doctrine of the fragment was stated in the writings of an eminent sophist; so we come to the conclusion that it was developed and diffused in sophistic circles by oral teaching, and that it became known to Critias and Plato in this way. Its originator we do not know. We might [pg 050] think of the sophist Thrasymachus, who in the first book of Plato's Republic maintains a point of view corresponding to that of Callicles in Gorgias. But what we otherwise learn of Thrasymachus is not suggestive of interest in religion, and the only statement of his as to that kind of thing which has come down to us tends to the denial of a providence, not denial of the gods. Quite recently Diagoras of Melos has been guessed at; this is empty talk, resulting at best in substituting x (or NN) for y.

If I have dwelt in such detail on the Sisyphus fragment, it is because it is our first direct and unmistakable evidence of ancient atheism. Here for the first time we meet with the direct statement which we have searched for in vain among all the preceding authors: that the gods of popular belief are fabrication pure and simple and without any corresponding reality, however remote. The nature of our tradition precludes our ascertaining whether such a statement might have been made earlier; but the probability is a priori that it was not. The whole development of ancient reasoning on religious questions, as far as we are able to survey it, leads in reality to the conclusion that atheism as an expressed (though perhaps not publicly expressed) confession of faith did not appear till the age of the sophists.
