THREE:VI.

THREE:Second.��The steam establishes the greatest possible elasticity in the connection between a hammer and the driving power, and at the same time serves to cushion the blows at both the top and bottom of the stroke, or on the top only, as occasion may require.In the face of such facts, to say, as Mr. Froude does, that Epicureanism was ��the creed of the men of science�� in the time of Julius Caesar111��an assertion directly contradicted by Lange112��is perhaps only of a piece with Mr. Froude��s usual inaccuracy when writing about ancient history; but such declarations as that of Mr. Frederic Pollock, that the Epicurean system56 ��was a genuine attempt at a scientific explanation of the world; and was in its day the solitary protest against the contempt of physics which prevailed in the other post-Aristotelian schools;��113 of Prof. Trezza, that the Epicurean school ��summed up in itself the most scientific elements of Greek antiquity;��114 of Dr. Woltjer, that ��with respect to the laws and principles of science, the Epicureans came nearest of all the ancients to the science of our own time;��115 and finally, of M. Ernest Renan, that Epicureanism was ��the great scientific school of antiquity,��116 are absolutely amazing. The eminent French critic just quoted has elsewhere observed, with perfect justice, that the scientific spirit is the negation of the supernatural; and perhaps he argues that the negation of the supernatural must, reciprocally, be the scientific spirit. But this is only true when such a negation is arrived at inductively, after a disinterested survey of the facts. Epicurus started with the denial of supernatural interference as a practical postulate, and then hunted about for whatever explanations of natural phenomena would suit his foregone conclusion. Moreover, an enquirer really animated by the scientific spirit studies the facts for their own sake; he studies them as they actually are, not resting content with alternative explanations; and he studies them to the fullest extent of which his powers are capable. Epicurus, on the contrary, declares that physics would not be worth attending to if the mind could be set free from religious terrors in any other manner;117 he will not let himself be tied down to any one theory if there are others equally inconsistent with divine agency to be had;118 and when his demands in this respect are satisfied, that is, when the appearances vulgarly ascribed to supernatural causation have been provided with natural causes, he leaves off.

THREE:Such arguments manifestly tell not only against Platonism, but against every kind of transcendental realism, from the natural theology of Paley to the dogmatic agnosticism of Mr. Herbert Spencer. A modern Aristotle might say that the hypothesis of a creative first cause, personal or otherwise, logically involves the assumption of as many original specific energies as there are qualities to be accounted for, and thus gives us the unnecessary trouble of counting everything twice over; that every difficulty and contradiction from which the transcendental assumption is intended to free us, must, on analysis, reappear in the assumption itself��for example, the God who is to deliver us from evil must be himself conceived as the creator of evil; that the infinite and absolute can neither cause, nor be apprehended by, the finite and relative; that to separate from Nature all the forces required for its perpetuation, and relegate them to a sphere apart, is a false antithesis and a sterile abstraction; lastly, that causation, whether efficient or final, once begun, cannot stop; that if this world is not self-existing, nothing is; that the mutual adaptation of thoughts in a designing intelligence requires to be accounted for just like any other adaptation; that if the relative involves the absolute, so also does the relation between the two involve another absolute, and so on to infinity.

THREE:It was their habit of teaching rhetoric as an art which raised the fiercest storm of indignation against Protagoras and his colleagues. The endeavour to discover rules for addressing a tribunal or a popular assembly in the manner best cal94culated to win their assent had originated quite independently of any philosophical theory. On the re-establishment of order, that is to say of popular government, in Sicily, many lawsuits arose out of events which had happened years before; and, owing to the lapse of time, demonstrative evidence was not available. Accordingly, recourse was had on both sides to arguments possessing a greater or less degree of probability. The art of putting such probable inferences so as to produce persuasion demanded great technical skill; and two Sicilians, Corax and Tisias by name, composed treatises on the subject. It would appear that the new-born art was taken up by Protagoras and developed in the direction of increased dialectical subtlety. We are informed that he undertook to make the worse appear the better reason; and this very soon came to be popularly considered as an accomplishment taught by all philosophers, Socrates among the rest. But if Protagoras merely meant that he would teach the art of reasoning, one hardly sees how he could have expressed himself otherwise, consistently with the antithetical style of his age. We should say more simply that a case is strengthened by the ability to argue it properly. It has not been shown that the Protagorean dialectic offered exceptional facilities for maintaining unjust pretensions. Taken, however, in connexion with the humanistic teaching, it had an unsettling and sceptical tendency. All belief and all practice rested on law, and law was the result of a convention made among men and ultimately produced by individual conviction. What one man had done another could undo. Religious tradition and natural right, the sole external standards, had already disappeared. There remained the test of self-consistency, and against this all the subtlety of the new dialectic was turned. The triumph of Eristic was to show that a speaker had contradicted himself, no matter how his statements might be worded. Moreover, now that reference to an objective reality was disallowed, words were put in the place95 of things and treated like concrete realities. The next step was to tear them out of the grammatical construction, where alone they possessed any truth or meaning, each being simultaneously credited with all the uses which at any time it might be made to fulfil. For example, if a man knew one thing he knew all, for he had knowledge, and knowledge is of everything knowable. Much that seems to us tedious or superfluous in Aristotle��s expositions was intended as a safeguard against this endless cavilling. Finally, negation itself was eliminated along with the possibility of falsehood and contradiction. For it was argued that ��nothing�� had no existence and could not be an object of thought.71
