Essays and Lectures

Some things, of course, are to be rejected a priori without entering into the subject: ‘As regards such miracles,’ he says, ¹⁵ ‘as that on a certain statue of Artemis rain or snow never falls though the statue stands in the open air, or that those who enter God’s shrine in Arcadia lose their natural shadows, I cannot really be expected to argue upon the subject. For these things are not only utterly improbable but absolutely impossible.’

‘For us to argue reasonably on an acknowledged absurdity is as vain a task as trying to catch water in a sieve; it is really to admit the possibility of the supernatural, which is the very point at issue.’

What Polybius felt was that to admit the possibility of a miracle is to annihilate the possibility of history: for just as scientific and chemical experiments would be either impossible or useless if exposed to the chance of continued interference on the part of some foreign body, so the laws and principles which govern history, the causes of phenomena, the evolution of progress, the whole science, in a word, of man’s dealings with his own race and with nature, will remain a sealed book to him who admits the possibility of extra-natural interference.

The stories of miracles, then, are to be rejected on a priori rational grounds, but in the case of events which we know to have happened the scientific historian will not rest till he has discovered their natural causes which, for instance, in the case of the wonderful rise of the Roman Empire – the most marvellous thing, Polybius says, which God ever brought about ¹⁶– are to be found in the excellence of their constitution (τῇ ἰδιότητι τῆς πολιτείας), the wisdom of their advisers, their splendid military arrangements, and their superstition (τῇ δεισιδαιμονίᾳ). For while Polybius regarded the revealed religion as, of course, objective reality of truth, ¹⁷ he laid great stress on its moral subjective influence, going, in one passage on the subject, even so far as almost to excuse the introduction of the supernatural in very small quantities into history on account of the extremely good effect it would have on pious people.

But perhaps there is no passage in the whole of ancient and modern history which breathes such a manly and splendid spirit of rationalism as one preserved to us in the Vatican – strange resting-place for it! – in which he treats of the terrible decay of population which had fallen on his native land in his own day, and which by the general orthodox public was regarded as a special judgment of God sending childlessness on women as a punishment for the sins of the people. For it was a disaster quite without parallel in the history of the land, and entirely unforeseen by any of its political-economy writers who, on the contrary, were always anticipating that danger would arise from an excess of population overrunning its means of subsistence, and becoming unmanageable through its size. Polybius, however, will have nothing to do with either priest or worker of miracles in this matter. He will not even seek that ‘sacred Heart of Greece,’ Delphi, Apollo’s shrine, whose inspiration even Thucydides admitted and before whose wisdom Socrates bowed. How foolish, he says, were the man who on this matter would pray to God. We must search for the rational causes, and the causes are seen to be clear, and the method of prevention also. He then proceeds to notice how all this arose from the general reluctance to marriage and to bearing the expense of educating a large family which resulted from the carelessness and avarice of the men of his day, and he explains on entirely rational principles the whole of this apparently supernatural judgment.

Now, it is to be borne in mind that while his rejection of miracles as violation of inviolable laws is entirely a priori– for discussion of such a matter is, of course, impossible for a rational thinker – yet his rejection of supernatural intervention rests entirely on the scientific grounds of the necessity of looking for natural causes. And he is quite logical in maintaining his position on these principles. For, where it is either difficult or impossible to assign any rational cause for phenomena, or to discover their laws, he acquiesces reluctantly in the alternative of admitting some extra-natural interference which his essentially scientific method of treating the matter has logically forced on him, approving, for instance, of prayers for rain, on the express ground that the laws of meteorology had not yet been ascertained. He would, of course, have been the first to welcome our modern discoveries in the matter. The passage in question is in every way one of the most interesting in his whole work, not, of course, as signifying any inclination on his part to acquiesce in the supernatural, but because it shows how essentially logical and rational his method of argument was, and how candid and fair his mind.

Having now examined Polybius’s attitude towards the supernatural and the general ideas which guided his research, I will proceed to examine the method he pursued in his scientific investigation of the complex phenomena of life. For, as I have said before in the course of this essay, what is important in all great writers is not so much the results they arrive at as the methods they pursue. The increased knowledge of facts may alter any conclusion in history as in physical science, and the canons of speculative historical credibility must be acknowledged to appeal rather to that subjective attitude of mind which we call the historic sense than to any formulated objective rules. But a scientific method is a gain for all time, and the true if not the only progress of historical criticism consists in the improvement of the instruments of research.

Now first, as regards his conception of history, I have already pointed out that it was to him essentially a search for causes, a problem to be solved, not a picture to be painted, a scientific investigation into laws and tendencies, not a mere romantic account of startling incident and wondrous adventure. Thucydides, in the opening of his great work, had sounded the first note of the scientific conception of history. ‘The absence of romance in my pages,’ he says, ‘will, I fear, detract somewhat from its value, but I have written my work not to be the exploit of a passing hour but as the possession of all time.’ ¹⁸ Polybius follows with words almost entirely similar. If, he says, we banish from history the consideration of causes, methods and motives (τὸ διὰ τί, καὶ πως, καὶ τίνος χάριν), and refuse to consider how far the result of anything is its rational consequent, what is left is a mere ἀγώνισμα, not a μάθημα, an oratorical essay which may give pleasure for the moment, but which is entirely without any scientific value for the explanation of the future. Elsewhere he says that ‘history robbed of the exposition of its causes and laws is a profitless thing, though it may allure a fool.’ And all through his history the same point is put forward and exemplified in every fashion.

So far for the conception of history. Now for the groundwork. As regards the character of the phenomena to be selected by the scientific investigator, Aristotle had laid down the general formula that nature should be studied in her normal manifestations. Polybius, true to his character of applying explicitly the principles implicit in the work of others, follows out the doctrine of Aristotle, and lays particular stress on the rational and undisturbed character of the development of the Roman constitution as affording special facilities for the discovery of the laws of its progress. Political revolutions result from causes either external or internal. The former are mere disturbing forces which lie outside the sphere of scientific calculation. It is the latter which are important for the establishing of principles and the elucidation of the sequences of rational evolution.

He thus may be said to have anticipated one of the most important truths of the modern methods of investigation: I mean that principle which lays down that just as the study of physiology should precede the study of pathology, just as the laws of disease are best discovered by the phenomena presented in health, so the method of arriving at all great social and political truths is by the investigation of those cases where development has been normal, rational and undisturbed.

The critical canon that the more a people has been interfered with, the more difficult it becomes to generalise the laws of its progress and to analyse the separate forces of its civilisation, is one the validity of which is now generally recognised by those who pretend to a scientific treatment of all history: and while we have seen that Aristotle anticipated it in a general formula, to Polybius belongs the honour of being the first to apply it explicitly in the sphere of history.

I have shown how to this great scientific historian the motive of his work was essentially the search for causes; and true to his analytical spirit he is careful to examine what a cause really is and in what part of the antecedents of any consequent it is to be looked for. To give an illustration: As regards the origin of the war with Perseus, some assigned as causes the expulsion of Abrupolis by Perseus, the expedition of the latter to Delphi, the plot against Eumenes and the seizure of the ambassadors in Bœotia; of these incidents the two former, Polybius points out, were merely the pretexts, the two latter merely the occasions of the war. The war was really a legacy left to Perseus by his father, who was determined to fight it out with Rome. ¹⁹

Here as elsewhere he is not originating any new idea. Thucydides had pointed out the difference between the real and the alleged cause, and the Aristotelian dictum about revolutions, οὐ περὶ μικρῶν ἀλλ’ ἐκ μικρῶν, draws the distinction between cause and occasion with the brilliancy of an epigram. But the explicit and rational investigation of the difference between αἰτία, ἀρχὴ, and πρόφασις was reserved for Polybius. No canon of historical criticism can be said to be of more real value than that involved in this distinction, and the overlooking of it has filled our histories with the contemptible accounts of the intrigues of courtiers and of kings and the petty plottings of backstairs influence – particulars interesting, no doubt, to those who would ascribe the Reformation to Anne Boleyn’s pretty face, the Persian war to the influence of a doctor or a curtain-lecture from Atossa, or the French Revolution to Madame de Maintenon, but without any value for those who aim at any scientific treatment of history.

But the question of method, to which I am compelled always to return, is not yet exhausted. There is another aspect in which it may be regarded, and I shall now proceed to treat of it.

One of the greatest difficulties with which the modern historian has to contend is the enormous complexity of the facts which come under his notice: D’Alembert’s suggestion that at the end of every century a selection of facts should be made and the rest burned (if it was really intended seriously) could not, of course, be entertained for a moment. A problem loses all its value when it becomes simplified, and the world would be all the poorer if the Sibyl of History burned her volumes. Besides, as Gibbon pointed out, ‘a Montesquieu will detect in the most insignificant fact relations which the vulgar overlook.’

Nor can the scientific investigator of history isolate the particular elements, which he desires to examine, from disturbing and extraneous causes, as the experimental chemist can do (though sometimes, as in the case of lunatic asylums and prisons, he is enabled to observe phenomena in a certain degree of isolation). So he is compelled either to use the deductive mode of arguing from general laws or to employ the method of abstraction, which gives a fictitious isolation to phenomena never so isolated in actual existence. And this is exactly what Polybius has done as well as Thucydides. For, as has been well remarked, there is in the works of these two writers a certain plastic unity of type and motive; whatever they write is penetrated through and through with a specific quality, a singleness and concentration of purpose, which we may contrast with the more comprehensive width as manifested not merely in the modern mind, but also in Herodotus. Thucydides, regarding society as influenced entirely by political motives, took no account of forces of a different nature, and consequently his results, like those of most modern political economists, have to be modified largely ²⁰ before they come to correspond with what we know was the actual state of fact. Similarly, Polybius will deal only with those forces which tended to bring the civilised world under the dominion of Rome (ix. 1), and in the Thucydidean spirit points out the want of picturesqueness and romance in his pages which is the result of the abstract method (τὸ μονοειδὲς τῆς συντάξεως) being careful also to tell us that his rejection of all other forces is essentially deliberate and the result of a preconceived theory and by no means due to carelessness of any kind.

Now, of the general value of the abstract method and the legality of its employment in the sphere of history, this is perhaps not the suitable occasion for any discussion. It is, however, in all ways worthy of note that Polybius is not merely conscious of, but dwells with particular weight on, the fact which is usually urged as the strongest objection to the employment of the abstract method – I mean the conception of a society as a sort of human organism whose parts are indissolubly connected with one another and all affected when one member is in any way agitated. This conception of the organic nature of society appears first in Plato and Aristotle, who apply it to cities. Polybius, as his wont is, expands it to be a general characteristic of all history. It is an idea of the very highest importance, especially to a man like Polybius whose thoughts are continually turned towards the essential unity of history and the impossibility of isolation.

Farther, as regards the particular method of investigating that group of phenomena obtained for him by the abstract method, he will adopt, he tells us, neither the purely deductive nor the purely inductive mode but the union of both. In other words, he formally adopts that method of analysis upon the importance of which I have dwelt before.

And lastly, while, without doubt, enormous simplicity in the elements under consideration is the result of the employment of the abstract method, even within the limit thus obtained a certain selection must be made, and a selection involves a theory. For the facts of life cannot be tabulated with as great an ease as the colours of birds and insects can be tabulated. Now, Polybius points out that those phenomena particularly are to be dwelt on which may serve as a παράδειγμα or sample, and show the character of the tendencies of the age as clearly as ‘a single drop from a full cask will be enough to disclose the nature of the whole contents.’ This recognition of the importance of single facts, not in themselves but because of the spirit they represent, is extremely scientific; for we know that from the single bone, or tooth even, the anatomist can recreate entirely the skeleton of the primeval horse, and the botanist tell the character of the flora and fauna of a district from a single specimen.

Regarding truth as ‘the most divine thing in Nature,’ the very ‘eye and light of history without which it moves a blind thing,’ Polybius spared no pains in the acquisition of historical materials or in the study of the sciences of politics and war, which he considered were so essential to the training of the scientific historian, and the labour he took is mirrored in the many ways in which he criticises other authorities.

There is something, as a rule, slightly contemptible about ancient criticism. The modern idea of the critic as the interpreter, the expounder of the beauty and excellence of the work he selects, seems quite unknown. Nothing can be more captious or unfair, for instance, than the method by which Aristotle criticised the ideal state of Plato in his ethical works, and the passages quoted by Polybius from Timæus show that the latter historian fully deserved the punning name given to him. But in Polybius there is, I think, little of that bitterness and pettiness of spirit which characterises most other writers, and an incidental story he tells of his relations with one of the historians whom he criticised shows that he was a man of great courtesy and refinement of taste – as, indeed, befitted one who had lived always in the society of those who were of great and noble birth.

Now, as regards the character of the canons by which he criticises the works of other authors, in the majority of cases he employs simply his own geographical and military knowledge, showing, for instance, the impossibility in the accounts given of Nabis’s march from Sparta simply by his acquaintance with the spots in question; or the inconsistency of those of the battle of Issus; or of the accounts given by Ephorus of the battles of Leuctra and Mantinea. In the latter case he says, if any one will take the trouble to measure out the ground of the site of the battle and then test the manœuvres given, he will find how inaccurate the accounts are.

In other cases he appeals to public documents, the importance of which he was always foremost in recognising; showing, for instance, by a document in the public archives of Rhodes how inaccurate were the accounts given of the battle of Lade by Zeno and Antisthenes. Or he appeals to psychological probability, rejecting, for instance, the scandalous stories told of Philip of Macedon, simply from the king’s general greatness of character, and arguing that a boy so well educated and so respectably connected as Demochares (xii. 14) could never have been guilty of that of which evil rumour accused him.

But the chief object of his literary censure is Timæus, who had been unsparing of his strictures on others. The general point which he makes against him, impugning his accuracy as a historian, is that he derived his knowledge of history not from the dangerous perils of a life of action but in the secure indolence of a narrow scholastic life. There is, indeed, no point on which he is so vehement as this. ‘A history,’ he says, ‘written in a library gives as lifeless and as inaccurate a picture of history as a painting which is copied not from a living animal but from a stuffed one.’

There is more difference, he says in another place, between the history of an eye-witness and that of one whose knowledge comes from books, than there is between the scenes of real life and the fictitious landscapes of theatrical scenery. Besides this, he enters into somewhat elaborate detailed criticism of passages where he thought Timæus was following a wrong method and perverting truth, passages which it will be worth while to examine in detail.

Timæus, from the fact of there being a Roman custom to shoot a war-horse on a stated day, argued back to the Trojan origin of that people. Polybius, on the other hand, points out that the inference is quite unwarrantable, because horse-sacrifices are ordinary institutions common to all barbarous tribes. Timæus here, as was common with Greek writers, is arguing back from some custom of the present to an historical event in the past. Polybius really is employing the comparative method, showing how the custom was an ordinary step in the civilisation of every early people.

In another place, ²¹ he shows how illogical is the scepticism of Timæus as regards the existence of the Bull of Phalaris simply by appealing to the statue of the Bull, which was still to be seen in Carthage; pointing out how impossible it was, on any other theory except that it belonged to Phalaris, to account for the presence in Carthage of a bull of this peculiar character with a door between his shoulders. But one of the great points which he uses against this Sicilian historian is in reference to the question of the origin of the Locrian colony. In accordance with the received tradition on the subject, Aristotle had represented the Locrian colony as founded by some Parthenidæ or slaves’ children, as they were called, a statement which seems to have roused the indignation of Timæus, who went to a good deal of trouble to confute this theory. He does so on the following grounds: —

First of all, he points out that in the ancient days the Greeks had no slaves at all, so the mention of them in the matter is an anachronism; and next he declares that he was shown in the Greek city of Locris certain ancient inscriptions in which their relation to the Italian city was expressed in terms of the position between parent and child, which showed also that mutual rights of citizenship were accorded to each city. Besides this, he appeals to various questions of improbability as regards their international relationship, on which Polybius takes diametrically opposite grounds which hardly call for discussion. And in favour of his own view he urges two points more: first, that the Lacedæmonians being allowed furlough for the purpose of seeing their wives at home, it was unlikely that the Locrians should not have had the same privilege; and next, that the Italian Locrians knew nothing of the Aristotelian version and had, on the contrary, very severe laws against adulterers, runaway slaves and the like. Now, most of these questions rest on mere probability, which is always such a subjective canon that an appeal to it is rarely conclusive. I would note, however, as regards the inscriptions which, if genuine, would of course have settled the matter, that Polybius looks on them as a mere invention on the part of Timæus, who, he remarks, gives no details about them, though, as a rule, he is over-anxious to give chapter and verse for everything. A somewhat more interesting point is that where he attacks Timæus for the introduction of fictitious speeches into his narrative; for on this point Polybius seems to be far in advance of the opinions held by literary men on the subject not merely in his own day, but for centuries after.

Herodotus had introduced speeches avowedly dramatic and fictitious. Thucydides states clearly that, where he was unable to find out what people really said, he put down what they ought to have said. Sallust alludes, it is true, to the fact of the speech he puts into the mouth of the tribune Memmius being essentially genuine, but the speeches given in the senate on the occasion of the Catilinarian conspiracy are very different from the same orations as they appear in Cicero. Livy makes his ancient Romans wrangle and chop logic with all the subtlety of a Hortensius or a Scævola. And even in later days, when shorthand reporters attended the debates of the senate and a Daily News was published in Rome, we find that one of the most celebrated speeches in Tacitus (that in which the Emperor Claudius gives the Gauls their freedom) is shown, by an inscription discovered recently at Lugdunum, to be entirely fabulous.

Upon the other hand, it must be borne in mind that these speeches were not intended to deceive; they were regarded merely as a certain dramatic element which it was allowable to introduce into history for the purpose of giving more life and reality to the narration, and were to be criticised, not as we should, by arguing how in an age before shorthand was known such a report was possible or how, in the failure of written documents, tradition could bring down such an accurate verbal account, but by the higher test of their psychological probability as regards the persons in whose mouths they are placed. An ancient historian in answer to modern criticism would say, probably, that these fictitious speeches were in reality more truthful than the actual ones, just as Aristotle claimed for poetry a higher degree of truth in comparison to history. The whole point is interesting as showing how far in advance of his age Polybius may be said to have been.

The last scientific historian, it is possible to gather from his writings what he considered were the characteristics of the ideal writer of history; and no small light will be thrown on the progress of historical criticism if we strive to collect and analyse what in Polybius are more or less scattered expressions. The ideal historian must be contemporary with the events he describes, or removed from them by one generation only. Where it is possible, he is to be an eye-witness of what he writes of; where that is out of his power he is to test all traditions and stories carefully and not to be ready to accept what is plausible in place of what is true. He is to be no bookworm living aloof from the experiences of the world in the artificial isolation of a university town, but a politician, a soldier, and a traveller, a man not merely of thought but of action, one who can do great things as well as write of them, who in the sphere of history could be what Byron and Æschylus were in the sphere of poetry, at once le chantre et le héros.

He is to keep before his eyes the fact that chance is merely a synonym for our ignorance; that the reign of law pervades the domain of history as much as it does that of political science. He is to accustom himself to look on all occasions for rational and natural causes. And while he is to recognise the practical utility of the supernatural, in an educational point of view, he is not himself to indulge in such intellectual beating of the air as to admit the possibility of the violation of inviolable laws, or to argue in a sphere wherein argument is a priori annihilated. He is to be free from all bias towards friend and country; he is to be courteous and gentle in criticism; he is not to regard history as a mere opportunity for splendid and tragic writing; nor is he to falsify truth for the sake of a paradox or an epigram.

While acknowledging the importance of particular facts as samples of higher truths, he is to take a broad and general view of humanity. He is to deal with the whole race and with the world, not with particular tribes or separate countries. He is to bear in mind that the world is really an organism wherein no one part can be moved without the others being affected also. He is to distinguish between cause and occasion, between the influence of general laws and particular fancies, and he is to remember that the greatest lessons of the world are contained in history and that it is the historian’s duty to manifest them so as to save nations from following those unwise policies which always lead to dishonour and ruin, and to teach individuals to apprehend by the intellectual culture of history those truths which else they would have to learn in the bitter school of experience.

Now, as regards his theory of the necessity of the historian’s being contemporary with the events he describes, so far as the historian is a mere narrator the remark is undoubtedly true. But to appreciate the harmony and rational position of the facts of a great epoch, to discover its laws, the causes which produced it and the effects which it generates, the scene must be viewed from a certain height and distance to be completely apprehended. A thoroughly contemporary historian such as Lord Clarendon or Thucydides is in reality part of the history he criticises; and, in the case of such contemporary historians as Fabius and Philistus, Polybius in compelled to acknowledge that they are misled by patriotic and other considerations. Against Polybius himself no such accusation can be made. He indeed of all men is able, as from some lofty tower, to discern the whole tendency of the ancient world, the triumph of Roman institutions and of Greek thought which is the last message of the old world and, in a more spiritual sense, has become the Gospel of the new.

One thing indeed he did not see, or if he saw it, he thought but little of it – how from the East there was spreading over the world, as a wave spreads, a spiritual inroad of new religions from the time when the Pessinuntine mother of the gods, a shapeless mass of stone, was brought to the eternal city by her holiest citizen, to the day when the ship Castor and Pollux stood in at Puteoli, and St. Paul turned his face towards martyrdom and victory at Rome. Polybius was able to predict, from his knowledge of the causes of revolutions and the tendencies of the various forms of governments, the uprising of that democratic tone of thought which, as soon as a seed is sown in the murder of the Gracchi and the exile of Marius, culminated as all democratic movements do culminate, in the supreme authority of one man, the lordship of the world under the world’s rightful lord, Caius Julius Cæsar. This, indeed, he saw in no uncertain way. But the turning of all men’s hearts to the East, the first glimmering of that splendid dawn which broke over the hills of Galilee and flooded the earth like wine, was hidden from his eyes.

There are many points in the description of the ideal historian which one may compare to the picture which Plato has given us of the ideal philosopher. They are both ‘spectators of all time and all existence.’ Nothing is contemptible in their eyes, for all things have a meaning, and they both walk in august reasonableness before all men, conscious of the workings of God yet free from all terror of mendicant priest or vagrant miracle-worker. But the parallel ends here. For the one stands aloof from the world-storm of sleet and hail, his eyes fixed on distant and sunlit heights, loving knowledge for the sake of knowledge and wisdom for the joy of wisdom, while the other is an eager actor in the world ever seeking to apply his knowledge to useful things. Both equally desire truth, but the one because of its utility, the other for its beauty. The historian regards it as the rational principle of all true history, and no more. To the other it comes as an all-pervading and mystic enthusiasm, ‘like the desire of strong wine, the craving of ambition, the passionate love of what is beautiful.’
