Plato

“ And, indeed, how can we imagine that perfect being is a mere everlasting form, devoid of motion and soul? for there can be no thought without soul, nor can soul be devoid of motion. But neither can thought or mind be devoid of some principle of rest or stability. And as children say entreatingly, 'Give us both,' so the philosopher must include both the moveable and immoveable in his idea of being. And yet, alas! he and we are in the same difficulty with which we reproached the dualists; for motion and rest are contradictions--how then can they both exist? ”

“ When we look far away into the primeval sources of thought and belief, do we suppose that the mere accident of our being the heirs of the Greek philosophers can give us a right to set ourselves up as having the true and only standard of reason in the world? Or when we contemplate the infinite worlds in the expanse of heaven can we imagine that a few meagre categories derived from language and invented by the genius of one or two great thinkers contain the secret of the universe? ”

“ For we must admit that the world and ourselves and the animals did not come into existence by chance, or the spontaneous working of nature, but by divine reason and knowledge. And there are not only divine creations but divine imitations, such as apparitions and shadows and reflections, which are equally the work of a divine mind. And there are human creations and human imitations too,—there is the actual house and the drawing of it. Nor must we forget that image-making may be an imitation of realities or an imitation of appearances, which last has been called by us phantastic. ”

“ If we suppose the universal separation of kinds, all theories alike are swept away; the patrons of a single principle of rest or of motion, or of a plurality of immutable ideas--all alike have the ground cut from under them; and all creators of the universe by theories of composition and division, whether out of or into a finite or infinite number of elemental forms, in alternation or continuance, share the same fate. Most ridiculous is the discomfiture which attends the opponents of predication, who, like the ventriloquist Eurycles, have the voice that answers them in their own breast. ”

“ If the Many were not, if all things were names of the One, and nothing could be predicated of any other thing, how could truth be distinguished from falsehood? The Eleatic philosopher would have replied that Being is alone true. But mankind had got beyond his barren abstractions: they were beginning to analyze, to classify, to define, to ask what is the nature of knowledge, opinion, sensation. ”

“ And though he can be scarcely said to have mixed much in the affairs of men, for, as his biographer tells us, 'he lived for thirty years in a single room,' yet he is far from being ignorant of the world. No one can read his writings without acquiring an insight into life. He loves to touch with the spear of logic the follies and self- deceptions of mankind, and make them appear in their natural form, stripped of the disguises of language and custom. He will not allow men to defend themselves by an appeal to one-sided or abstract principles. ”

“ STRANGER: The common notion pervading all these objects, which you speak of as many, and yet call by the single name of image, as though it were the unity under which they were all included. How will you maintain your ground against him?
THEAETETUS: How, Stranger, can I describe an image except as something fashioned in the likeness of the true? ”

“ But how could philosophy explain the connexion of ideas, how justify the passing of them into one another? The abstractions of one, other, being, not-being, rest, motion, individual, universal, which successive generations of philosophers had recently discovered, seemed to be beyond the reach of human thought, like stars shining in a distant heaven. ”

“ For Hegel has found admirers in England and Scotland when his popularity in Germany has departed, and he, like the philosophers whom he criticizes, is of the past. No other thinker has ever dissected the human mind with equal patience and minuteness. He has lightened the burden of thought because he has shown us that the chains which we wear are of our own forging. To be able to place ourselves not only above the opinions of men but above their modes of thinking, is a great height of philosophy. ”

“ Nobly said, Theaetetus, and if I thought that you were one of those who would hereafter change your mind, I would have gently argued with you, and forced you to assent; but as I perceive that you will come of yourself and without any argument of mine, to that belief which, as you say, attracts you, I will not forestall the work of time. Let me suppose, then, that things which are said to be made by nature are the work of divine art, and that things which are made by man out of these are works of human art. And so there are two kinds of making and production, the one human and the other divine. ”

“ As the Pre- Socratic philosopher failed to distinguish between the universal and the true, while he placed the particulars of sense under the false and apparent, so Plato appears to identify negation with falsehood, or is unable to distinguish them. The greatest service rendered by him to mental science is the recognition of the communion of classes, which, although based by him on his account of 'Not-being,' is independent of it. ”

“ Hegel, if not the greatest philosopher, is certainly the greatest critic of philosophy who ever lived. No one else has equally mastered the opinions of his predecessors or traced the connexion of them in the same manner. No one has equally raised the human mind above the trivialities of the common logic and the unmeaningness of 'mere' abstractions, and above imaginary possibilities, which, as he truly says, have no place in philosophy. No one has won so much for the kingdom of ideas. ”

“ Nor can any efforts of speculative thinkers or of soldiers and statesmen materially quicken the 'process of the suns.'
Hegel was quite sensible how great would be the difficulty of presenting philosophy to mankind under the form of opposites. Most of us live in the one-sided truth which the understanding offers to us, and if occasionally we come across difficulties like the time-honoured controversy of necessity and free-will, or the Eleatic puzzle of Achilles and the tortoise, we relegate some of them to the sphere of mystery, others to the book of riddles, and go on our way rejoicing. ”

“ He will at once point out that he is compelling us to contradict ourselves, by affirming being of not-being. I think that we must cease to look for him in the class of imitators.
But ought we to give him up? 'I should say, certainly not.' Then I fear that I must lay hands on my father Parmenides; but do not call me a parricide; for there is no way out of the difficulty except to show that in some sense not-being is; and if this is not admitted, no one can speak of falsehood, or false opinion, or imitation, without falling into a contradiction. ”

“ But we may acknowledge that the great thinker has thrown a light on many parts of human knowledge, and has solved many difficulties. We cannot receive his doctrine of opposites as the last word of philosophy, but still we may regard it as a very important contribution to logic. We cannot affirm that words have no meaning when taken out of their connexion in the history of thought. But we recognize that their meaning is to a great extent due to association, and to their correlation with one another. We see the advantage of viewing in the concrete what mankind regard only in the abstract. ”

“ But we cannot conceive how all the thoughts of men that ever were, which are themselves subject to so many external conditions of climate, country, and the like, even if regarded as the single thought of a Divine Being, can be supposed to have made the world. We appear to be only wrapping up ourselves in our own conceits--to be confusing cause and effect--to be losing the distinction between reflection and action, between the human and divine. ”

“ In all things, if we leave out details, a certain degree of order begins to appear; at any rate we can make an order which, with a little exaggeration or disproportion in some of the parts, will cover the whole field of philosophy. But are we therefore justified in saying that ideas are the causes of the great movement of the world rather than the personalities which conceived them? The great man is the expression of his time, and there may be peculiar difficulties in his age which he cannot overcome. ”
