Now, it is to be observed that in this latter passage, as well as elsewhere, Thucydides is in no sense of the word a sceptic as regards his attitude towards the truth of these ancient legends.
Agamemnon and Atreus, Theseus and Eurystheus, even Minos, about whom Herodotus has some doubts, are to him as real personages as Alcibiades or Gylippus. The points in his historical criticism of the past are, first, his rejection of all extra-natural interference, and, secondly, the attributing to these ancient heroes the motives and modes of thought of his own day. The present was to him the key to the explanation of the past, as it was to the prediction of the future.
Now, as regards his attitude towards the supernatural he is at one with modern science. We too know that, just as the primeval coal-beds reveal to us the traces of rain-drops and other atmospheric phenomena similar to those of our own day, so, in estimating the history of the past, the introduction of no force must be allowed whose workings we cannot observe among the phenomena around us. To lay down canons of ultra-historical credibility for the explanation of events which happen to have preceded us by a few thousand years, is as thoroughly unscientific as it is to intermingle preternatural in geological theories.
Whatever the canons of art may be, no difficulty in history is so great as to warrant the introduction of a spirit of spirit θεὸς ἀπὸ μηχανῆς, in the sense of a violation of the laws of nature.
Upon the other point, however, Thucydides falls into an anachronism. To refuse to allow the workings of chivalrous and self-denying motives among the knights of the Trojan crusade, because he saw none in the faction-loving Athenian of his own day, is to show an entire ignorance of the various characteristics of human nature developing under different circumstances, and to deny to a primitive chieftain like Agamemnon that authority founded on opinion, to which we give the name of divine right, is to fall into an historical error quite as gross as attributing to Atreus the courting of the populace (τεθεραπευκότα τὸν δῆμον) with a view to the Mycenean throne.
The general method of historical criticism pursued by Thucydides having been thus indicated, it remains to proceed more into detail as regards those particular points where he claims for himself a more rational method of estimating evidence than either the public or his predecessors possessed.
‘So little pains,’ he remarks, ‘do the vulgar take in the investigation of truth, satisfied with their preconceived opinions,’ that the majority of the Greeks believe in a Pitanate cohort of the Spartan army and in a double vote being the prerogative of the Spartan kings, neither of which opinions has any foundation in fact. But the chief point on which he lays stress as evincing the ‘uncritical way with which men receive legends, even the legends of their own country,’ is the entire baselessness of the common Athenian tradition in which Harmodios and Aristogeiton were represented as the patriotic liberators of Athens from the Peisistratid tyranny. So far, he points out, from the love of freedom being their motive, both of them were influenced by merely personal considerations, Aristogeiton being jealous of Hipparchos’ attention to Harmodios, then a beautiful boy in the flower of Greek loveliness, while the latter’s indignation was aroused by an insult offered to his sister by the prince.
Their motives, then, were personal revenge, while the result of their conspiracy served only to rivet more tightly the chains of servitude which bound Athens to the Peisistratid house, for Hipparchos, whom they killed, was only the tyrant’s younger brother, and not the tyrant himself.
To prove his theory that Hippias was the elder, he appeals to the evidence afforded by a public inscription in which his name occurs immediately after that of his father, a point which he thinks shows that he was the eldest, and so the heir. This view he further corroborates by another inscription, on the altar of Apollo, which mentions the children of Hippias and not those of his brothers; ‘for it was natural for the eldest to be married first’; and besides this, on the score of general probability he points out that, had Hippias been the younger, he would not have so easily obtained the tyranny on the death of Hipparchos.
Now, what is important in Thucydides, as evinced in the treatment of legend generally, is not the results he arrived at, but the method by which he works. The first great rationalistic historian, he may be said to have paved the way for all those who followed after him, though it must always be remembered that, while the total absence in his pages of all the mystical paraphernalia of the supernatural theory of life is an advance in the progress of rationalism, and an era in scientific history, whose importance could never be over-estimated, yet we find along with it a total absence of any mention of those various social and economical forces which form such important factors in the evolution of the world, and to which Herodotus rightly gave great prominence in his immortal work. The history of Thucydides is essentially one-sided and incomplete. The intricate details of sieges and battles, subjects with which the historian proper has really nothing to do except so far as they may throw light on the spirit of the age, we would readily exchange for some notice of the condition of private society in Athens, or the influence and position of women.
There is an advance in the method of historical criticism; there is an advance in the conception and motive of history itself; for in Thucydides we may discern that natural reaction against the intrusion of didactic and theological considerations into the sphere of the pure intellect, the spirit of which may be found in the Euripidean treatment of tragedy and the later schools of art, as well as in the Platonic conception of science.
History, no doubt, has splendid lessons for our instruction, just as all good art comes to us as the herald of the noblest truth. But, to set before either the painter or the historian the inculcation of moral lessons as an aim to be consciously pursued, is to miss entirely the true motive and characteristic both of art and history, which is in the one case the creation of beauty, in the other the discovery of the laws of the evolution of progress: Il ne faut demander de l’Art que l’Art, du passé que le passé.
Herodotus wrote to illustrate the wonderful ways of Providence and the nemesis that falls on sin, and his work is a good example of the truth that nothing can dispense with criticism so much as a moral aim. Thucydides has no creed to preach, no doctrine to prove. He analyses the results which follow inevitably from certain antecedents, in order that on a recurrence of the same crisis men may know how to act.
His object was to discover the laws of the past so as to serve as a light to illumine the future. We must not confuse the recognition of the utility of history with any ideas of a didactic aim. Two points more in Thucydides remain for our consideration: his treatment of the rise of Greek civilisation, and of the primitive condition of Hellas, as well as the question how far can he be said really to have recognised the existence of laws regulating the complex phenomena of life.
III
The investigation into the two great problems of the origin of society and the philosophy of history occupies such an important position in the evolution of Greek thought that, to obtain any clear view of the workings of the critical spirit, it will be necessary to trace at some length their rise and scientific development as evinced not merely in the works of historians proper, but also in the philosophical treatises of Plato and Aristotle. The important position which these two great thinkers occupy in the progress of historical criticism can hardly be over-estimated. I do not mean merely as regards their treatment of the Greek Bible, and Plato’s endeavours to purge sacred history of its immorality by the application of ethical canons at the time when Aristotle was beginning to undermine the basis of miracles by his scientific conception of law, but with reference to these two wider questions of the rise
