THREE:So far, virtue was with the Greeks what it must inevitably be with all men at first, chiefly self-regarding, a refined form of prudence. Moreover, other-regarding virtues gave less scope for reflection, being originally comprehended under obedience to the law. But there were two circumstances which could not long escape their notice; first, that fraud and violence are often, at least apparently, profitable to those who perpetrate them, a fact bitterly remarked by Hesiod;50 and secondly, that society cannot hold together without justice. It was long before Governments grew up willing and able to protect their subjects from mutual aggressions, nor does positive law create morality, but implies it, and could not be worked without it. Nor could international obligations be enforced by a superior tribunal; hence they have remained down to the present day a fertile theme for ethical discussion. It is at this point that morality forms a junction with religion, the history of which is highly interesting, but which can here be64 only briefly traced. The Olympian divinities, as placed before us by Homer, are anything but moral. Their conduct towards each other is that of a dissolute nobility; towards men it is that of unscrupulous partisans and patrons. A loyal adherence to friends and gratitude for sacrificial offerings are their most respectable characteristics, raising them already a little above the nature-powers whence they were derived. Now, mark how they first become moralised. It is by being made witnesses to an oath. Any one who is called in to testify to a promise feels aggrieved if it is broken, looking on the breach as an insult to his own dignity. As the Third Commandment well puts it, his name has been taken in vain. Thus it happened that the same gods who left every other crime unpunished, visited perjury with severe and speedy retribution, continued even after the offenders death.51 Respect for a contract is the primary form of moral obligation, and still seems to possess a peculiar hold over uneducated minds. We see every day how many persons will abstain from actions which they know to be immoral because they have given their word to that effect, not because the actions themselves are wrong. And for that reason law courts would be more willing to enforce contracts than to redress injuries. If, then, one person inflicted damage on another, he might afterwards, in order to escape retaliation from the injured party, or from his family, engage to give satisfaction, and the court would compel him to redeem his promise.52 Thus contract, by procuring redress for every species of wrong, would gradually extend its own obligatory character to abstinence from injury in general, and the divine sanctions primarily invoked on behalf of oaths would be extended, with them, over the whole domain of moral conduct.We have already observed that Scepticism among the ancients was often cultivated in connexion with some positive doctrine which it indirectly served to recommend. In the case of its last supporters, this was the study of medicine on an empirical as opposed to a deductive method. The Sceptical contention is that we cannot go beyond appearances; the empirical contention is, that all knowledge comes to us from experience, and that this only shows us how phenomena are related to one another, not how they are related to their underlying causes, whether efficient or final. These allied points of view have been brought into still more intimate association by modern thought, which, as will be shown in the concluding chapter, has sprung from a modified form of the ancient Scepticism, powerfully aided by a simultaneous development of physical science. At the same time, the new school have succeeded in shaking off the narrowness and timidity of their predecessors, who were still so far under the influence of the old dogmatists as to believe that there was an inherent opposition between observation and reasoning in the methods of discovery, between facts and explanations in the truths of science, and between antecedence and causation in the realities of Nature. In this respect, astronomy has done more for the right adjustment of our conceptions than any190 other branch of knowledge; and it is remarkable that Sextus Empiricus, the last eminent representative of ancient Scepticism, and the only one (unless Cicero is to be called a Sceptic) whose writings are still extant, should expressly except astronomy from the destructive criticism to which he subjects the whole range of studies included in what we should call the university curriculum of his time.301 We need not enter into an analysis of the ponderous compilation referred to; for nearly every point of interest which it comprises has already been touched on in the course of our investigation; and Sextus differs only from his predecessors by adding the arguments of the New Academy to those of Protagoras and Pyrrho, thus completing the Sceptical cycle. It will be enough to notice the singular circumstance that so copious and careful an enumeration of the grounds which it was possible to urge against dogmatismincluding, as we have seen, many still employed for the same or other purposes,should have omitted the two most powerful solvents of any. These were left for the exquisite critical acumen of Hume to discover. They relate to the conception of causation, and to the conception of our own personality as an indivisible, continuously existing substance, being attempts to show that both involve assumptions of an illegitimate character. Sextus comes up to the very verge of Humes objection to the former when he observes that causation implies relation, which can only exist in thought;302 but he does not ask how we come to think such a relation, still less does he connect it with the perception of phenomenal antecedence; and his attacks on the various mental faculties assumed by psychologists pass over the fundamental postulate of personal identity, thus leaving Descartes what seemed a safe foundation whereon to rebuild the edifice of metaphysical philosophy.
