I had a rather amusing meeting at Tongres, with a Netherland colleague, who was on his way to Louvain.Macaulay has spoken as if the Platonic philosophy was totally unrelated to the material wants of men. This, however, is a mistake. It is true that, in the Republic, science is not regarded as an instrument for heaping up fresh luxuries, or for curing the diseases which luxury breeds; but only because its purpose is held to be the discovery of those conditions under which a healthy, happy, and virtuous race can best be reared. The art of the true statesman is to weave the web of life with perfect skill, to bring together those couples from whose union the noblest progeny shall issue; and it is only by mastering the laws of the physical universe that this art can be acquired. Plato knew no natural laws but those of mathematics and astronomy; consequently, he set far too much store on the times and seasons at which bride and bridegroom were to meet, and on the numerical ratios by which they were supposed to be determined. He even tells243 us about a mysterious formula for discovering the nuptial number, by which the ingenuity of commentators has been considerably exercised. The true laws by which marriage should be regulated among a civilised people have remained wrapped in still more impenetrable darkness. Whatever may be the best solution, it can hardly fail to differ in many respects from our present customs. It cannot be right that the most important act in the life of a human being should be determined by social ambition, by avarice, by vanity, by pique, or by accidentin a word, by the most contemptible impulses of which human nature is susceptible; nor is it to be expected that sexual selection will always necessitate the employment of insincerity, adulation, and bribery by one of the parties concerned, while fostering in the other credulity, egoism, jealousy, capriciousness, and petty tyrannythe very qualities which a wise training would have for its object to root out.145

THREE:The analogy between modern Europe and the Roman262 empire is, however, as we have already hinted, merely superficial. It has been shown in the course of our analysis that to ensure the triumph of superstition in the old world something more was necessary than the destruction of aristocratic government. Every feeling of libertyexcept the liberty to dieand almost every feeling of self-respect had to be crushed out by the establishment of an authoritative hierarchy extending from the Emperor down to the meanest slaves, before the voice of Hellenic reason could be hushed. But among ourselves it is rather of the opposite faultof too great independence and individualismthat complaints are heard. If we occasionally see a hereditary monarch or a popular minister invested with despotic power, this phenomenon is probably due to the circumstances of a revolutionary period, and will in course of time become more and more exceptional. Flatterers, parasites, and will-hunters are not an increasing but a diminishing class. Modern officers, as a body, show none of that contempt for reasoning and amenability to superstition which characterised the Roman centurions; in France, military men are even distinguished for their deadly hatred of priests. And, what is more important than any other element in our comparison, the reserves which modern civilisation is bringing to the front are of a widely different intellectual stature and equipment from their predecessors under Augustus and the Antonines. Since the reorganisation of industry by science, millions of working-men have received an education which prepares them to understand the universality of law much better than the literary education given to their social superiors, which, indeed, bears a remarkable resemblance to the rhetorical and sophistical training enjoyed by the contemporaries of Maximus Tyrius and Apuleius. If as much cannot be said of the middle classes, they are at any rate far more enlightened than Roman provincials, and are likely to improve still further with the spread of educationanother peculiarly modern phenomenon.263 On this point we have, indeed, something better to argue from than priori probabilities. We see before our eyes the rationalistic movement advancing pari passu with the democratic movement, and, in some countries, overtly aided by it. To say that this alliance has been provoked by an accidental and temporary association of monarchy and aristocracy with Church establishments, is a superficial explanation. The paid advocates of delusion know well where their interest lies. They have learned by experience that democracy means the education of the people, and that the education of the people means the loss of their own prestige. And they know also that, in many cases, the people are already sufficiently educated to use political power, once they have obtained it, for the summary destruction of organised and endowed superstition. What has been said of popular influence applies equally to the influence of women. When they were either not educated at all or only received a literary education, every improvement in their position was simply so much ground gained for superstition. The prospect is very different now. Women are beginning to receive a training like that of men, or rather a training superior to what all but a very few men have hitherto enjoyed. And the result is that, wherever this experiment has been tried, they have flung aside traditional beliefs once supposed to be a necessity of their nature even more decisively and disdainfully than have the professors by whom they are taught.
CHAPTER XXXVIII. MAITRANK STRIKES.The greatest of Roman orators and writers was also the first Roman that held opinions of his own in philosophy. How much original thought occurs in his voluminous contributions to the literature of the subject is more than we can determine, the Greek authorities on which he drew being known almost exclusively through the references to them contained in his disquisitions. But, judging from the evidence before us, carefully sifted as it has been by German scholars, we should feel disposed to assign him a foremost rank among the thinkers of an age certainly not distinguished either for fertility or for depth of thought. It seems clear that he gave a new basis to the eclectic tendencies of his contemporaries, and that this basis was subsequently accepted by other philosophers whose speculative capacity has never been questioned. Cicero describes himself as an adherent of the New Academy, and expressly claims to have reasserted its principles after they had fallen into neglect among the Greeks, more particularly as against his own old master Antiochus, whose Stoicising theory of cognition he agrees with Philo in repudiating.269 Like Philo also, he bases certainty on the twofold ground of a moral necessity for acting on our beliefs,270 and the existence of moral intuitions, or natural tendencies to believe in the mind itself;271 or, perhaps, more properly speaking, on the single ground of a moral sense. This, as already stated, was unquestionably a reproduction of the Platonic ideas under their subjective aspect. But in his general views about the nature and limits171 of human knowledge, Cicero leaves the Academy behind him, and goes back to Socrates. Perhaps no two men of great genius could be more unlike than these two,for us the most living figures in ancient history if not in all history,the Roman being as much a type of time-servingness and vacillation as the Athenian was of consistency and resolute independence. Yet, in its mere external results, the philosophy of Socrates is perhaps more faithfully reproduced by Cicero than by any subsequent enquirer; and the differences between them are easily accounted for by the long interval separating their ages from one another. Each set out with the same eager desire to collect knowledge from every quarter; each sought above all things for that kind of knowledge which seemed to be of the greatest practical importance; and each was led to believe that this did not include speculations relating to the physical world; one great motive to the partial scepticism professed by both being the irreconcilable disagreement of those who had attempted an explanation of its mysteries. The deeper ground of mans ignorance in this respect was stated somewhat differently by each; or perhaps we should say that the same reason is expressed in a mythical form by the one and in a scientific form by the other. Socrates held that the nature of things is a secret which the gods have reserved for themselves; while, in Ciceros opinion, the heavens are so remote, the interior of the earth so dark, the mechanism of our own bodies so complicated and subtle, as to be placed beyond the reach of fruitful observation.272 Nor did this deprivation seem any great hardship to either, since, as citizens of great and free states, both were pre-eminently interested in the study of social life; and it is characteristic of their common tendency that both should have been not only great talkers and observers but also great readers of ancient literature.273A remarkable strike had taken place in the Leo XIII Hospital. The head of this institution, Dr. Tits, also had been taken as a hostage. It was the most blackguardly act one can think of, to take away the man who had spent night and day mostly nursing wounded Germans. Dr. Noyons found it so harsh that he took counsel with the other doctors, and they decided not to resume work before Dr. Tits came back. This of course happened immediately.21(1.)
