The theorems, formul?, constants, tables, and rules, which are generally termed the principles of mechanics, are in a sense only symbols of principles; and it is possible, as many facts will prove, for a learner to master the theories and symbols of mechanical principles, and yet not be able to turn such knowledge [2] to practical account.The idea of Nature, or of the universe, or of human history as a wholebut for its evil associations with fanaticism and superstition, we should gladly say the belief in Godis one the ethical value of which can be more easily felt than analysed. We do not agree with the most brilliant of the English Positivists in restricting its influence to the aesthetic emotions.106 The elevating influence of these should be fully51 recognised; but the place due to more severely intellectual pursuits in moral training is greater far. Whatever studies tend to withdraw us from the petty circle of our personal interests and pleasures, are indirectly favourable to the preponderance of social over selfish impulses; and the service thus rendered is amply repaid, since these very studies necessitate for their continuance a large expenditure of moral energy. It might even be contended that the influence of speculation on practice is determined by the previous influence of practice on speculation. Physical laws act as an armature to the law of duty, extending and perpetuating its grasp on the minds of men; but it was through the magnetism of duty that their confused currents were first drawn into parallelism and harmony with its attraction. We have just seen how, from this point of view, the interpretation of evolution by conscience might be substituted for the interpretation of conscience by evolution. Yet those who base morality on religion, or give faith precedence over works, have discerned with a sure though dim instinct the dependence of noble and far-sighted action on some paramount intellectual initiative and control; in other words, the highest ethical ideals are conditioned by the highest philosophical generalisations. Before the Greeks could think of each man as a citizen of the world, and as bound to all other rational beings by virtue of a common origin and a common abode, it was first necessary that they should think of the world itself as an orderly and comprehensive whole. And what was once a creative, still continues to work as an educating force. Our aspirations towards agreement with ourselves and with humanity as a whole are strengthened by the contemplation of that supreme unity which, even if it be but the glorified reflection of our individual or generic identity, still remains the idea in and through which those lesser unities were first completely realisedthe idea which has originated all mans most fruitful faiths, and will at last absorb them all. Meanwhile our highest devotion can hardly find more fitting52 utterance than in the prayer which once rose to a Stoics lips:
THREE:"Do you mean to say you know anything about it?" Lawrence asked."I fancy I can see a way out of the difficulty," he said. "I do not wish to pry into your affairs, but in a novelist's business one gets to know things. And I, too, am in a great quandary. Do you recollect the flower farm near Ajaccio?"
THREE:The famous theses of Gorgias were quoted in a former chapter as an illustration of the tactics pursued by Greek Humanism in its controversy with physical science. They must be noticed again in the present connexion, on account of their bearing on the development of scepticism, and as having inaugurated a method of reasoning often employed in subsequent attacks, directed, not against the whole of knowledge, but against particular parts of it. The scepticism of Protagoras rested on the assumption that there is an external reality from the reaction of which with mind all our perceptions proceed. Neither of these two factors can be known apart from the other, and as both are in a constant flux, our knowledge of the resulting compound at one time does not show what it has been or will be at another time. But Gorgias altogether denied the existence of any objective reality; and he attempted to disprove it by an analytical instead of a synthetic argument, laying down a series of disjunctive propositions, and upsetting the different alternatives in succession. Existence must be either something or nothing, or both together; and if something, it must be either finite or infinite, or both, and either one or many, or both. His argument against an infinite existence is altogether futile; but it serves to illustrate the undeveloped state of reflection at that period. The eternity of the world is confounded with its unlimited extension in space: and this hypothesis, again, is met by the transparent quibble that the world, not being in any one place, must be nowhere or not at all. And the alternative that the world has not always existed is refuted by the unproved assumption, which, apparently, no Greek philosopher ever thought of disputing, that nothing can begin without being caused by something else. Still, however contemptible such reasonings may seem,131 it is obvious that in them we have the first crude form of the famous antinomies by which Kant long afterwards sought to prove the impossibility of a world existing in space and time apart from a percipient subject, and which have since been used to establish in a more general way the unknowability of existence as such. It will also be observed that the sceptical arguments respectively derived from the relativity of thought and from the contradictions inherent in its ultimate products are run together by modern agnostics. But no reason that we can remember has ever been given to show that an idea is necessarily subjective because it is self-contradictory.
