Finally, while the attempt to attain extreme accuracy of definition was leading to the destruction of all thought and all reality within the Socratic school, the dialectic method had been taken up and parodied in a very coarse style by a class of persons called Eristics. These men had, to some extent, usurped the place of the elder Sophists as paid instructors of youth; but their only accomplishment was to upset every possible assertion by a series of verbal juggles. One of their favourite paradoxes was to deny the reality of falsehood on the Parmenidean principle that nothing cannot exist. Plato satirises their method in the Euthydmus, and makes a much more serious attempt to meet it in the Sophist; two Dialogues which seem to have been composed not far from one another.156 The Sophist effects a considerable simplification in the ideal theory by resolving negation into difference, and altogether omitting the notions of unity and plurality,perhaps as a result of the investiga265tions contained in the Parmenides, another dialogue belonging to the same group, where the couple referred to are analysed with great minuteness, and are shown to be infected with numerous self-contradictions. The remaining five ideas of Existence, Sameness, Difference, Rest, and Motion, are allowed to stand; but the fact of their inseparable connexion is brought out with great force and clearness. The enquiry is one of considerable interest, including, as it does, the earliest known analysis of predication, and forming an indispensable link in the transition from Platonic to Aristotelian logicthat is to say, from the theory of definition and classification to the theory of syllogism.
Notwithstanding the radical error of Aristotles philosophythe false abstraction and isolation of the intellectual from the material sphere in Nature and in human lifeit may furnish a useful corrective to the much falser philosophy insinuated, if not inculcated, by some moralists of our own age and country. Taken altogether, the teaching of these writers seems to be that the industry which addresses itself to the satisfaction of our material wants is much more meritorious than the artistic work which gives us direct aesthetic enjoyment, or the literary work which stimulates and gratifies our intellectual cravings; while within the artistic sphere fidelity of portraiture is preferred to the creation of ideal beauty; and within the intellectual sphere, mere observation of facts is set above the theorising power by which facts are unified and explained. Some of the school to whom we allude are great enemies of materialism; but teaching like theirs is materialism of the worst description. Consistently carried400 out, it would first reduce Europe to the level of China, and then reduce the whole human race to the level of bees or beavers. They forget that when we were all comfortably clothed, housed, and fed, our true lives would have only just begun. The choice would then remain between some new refinement of animal appetite and the theorising activity which, according to Aristotle, is the absolute end, every other activity being only a means for its attainment. There is not, indeed, such a fundamental distinction as he supposed, for activities of every order are connected by a continual reciprocity of services; but this only amounts to saying that the highest knowledge is a means to every other end no less than an end in itself. Aristotle is also fully justified in urging the necessity of leisure as a condition of intellectual progress. We may add that it is a leisure which is amply earned, for without it industrial production could not be maintained at its present height. Nor should the same standard of perfection be imposed on spiritual as on material labour. The latter could not be carried on at all unless success, and not failure, were the rule. It is otherwise in the ideal sphere. There the proportions are necessarily reversed. We must be content if out of a thousand guesses and trials one should contribute something to the immortal heritage of truth. Yet we may hope that this will not always be so, that the great discoveries and creations wrought out through the waste of innumerable lives are not only the expiation of all error and suffering in the past, but are also the pledge of a future when such sacrifices shall no longer be required.
ONE:Text-books, such as relate to construction, consist generally of examples, drawings, and explanations of machines, gearing, tools, and so on; such examples are of use to a learner, no doubt, but in most cases he can examine the machines themselves, and on entering a shop is brought at once in contact not only with the machines but also with their operation. Examples and drawings relate to how machines are constructed, but when a learner comes to the actual operation of machines, a new and more interesting problem is reached in the reasons why they are so constructed.
ONE:"Wonderful!" she cried. "Ah, to have a gift like that. To think that the human voice----"Machines are composed of parts connected together by rigid and movable joints; rigid joints are necessary because of the expense, and in most cases the impossibility, of constructing framing and other fixed detail in one piece.
TWO:The same, in self-same place, and by itselfBut it is equally certain that at Lige as well as at Namur and Antwerp the Austrian thirty-point-five mortars were used, siege-guns chiefly, and these were taken by the German soldiers for forty-two's. These Austrian mortars were equally misnamed in German, French, and even Netherland illustrated papers.
TWO:"Well, there is a huge fire yonder; everything is burning!""Four days ago her husband was buried. As he was addressing the League of Old-Retraitants at Cherath he was seized by a paralytic stroke, which proved fatal. She has no longer a home, beautiful Villa Rustica being completely burnt out, and now in ruins. But she refuses to return to The Netherlands, as she is still able to be of service to the people here.
THREE:It remains to glance at another aspect of the dialectic method first developed on a great scale by Plato, and first fully defined by Aristotle, but already playing a certain part in the Socratic teaching. This is the testing of common assumptions by pushing them to their logical conclusion, and rejecting those which lead to consequences inconsistent with themselves. So understood, dialectic means the complete elimination of inconsistency, and has ever since remained the most powerful weapon of philosophical criticism. To take an instance near at hand, it is constantly employed by thinkers so radically different as Mr. Herbert Spencer and Professor T. H. Green; while it has been generalised into an objective law of Nature and history, with dazzling though only momentary success, by Hegel and his school.
THREE:146It was with the help of this theory that Epicurus explained and defended the current belief in the existence of gods. The divine inhabitants of the intermundia, or empty spaces separating world from world, are, like all other beings, composed of atoms, and are continually throwing off fine images, some of which make their way unaltered to our earth and reveal themselves to the senses, particularly during sleep, when we are most alive to the subtlest impressions on our perceptive organs. With the usual irrationality of a theologian, Epicurus remained blind to the fact that gods who were constantly throwing off even the very thinnest films could not possibly survive through all eternity. Neither did he explain how images larger than the pupil of the eye could pass through its aperture while preserving their original proportions unaltered.
