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. Most men (like Aristotle) have been accustomed to regard a contradiction in terms as the end of strife; to be told that contradiction is the life and mainspring of the intellectual world is indeed a paradox to them. Every abstraction is at first the enemy of every other, yet they are linked together, each with all, in the chain of Being. The struggle for existence is not confined to the animals, but appears in the kingdom of thought. The divisions which arise in thought between the physical and moral and between the moral and intellectual, and the like, are deepened and widened by the formal logic which elevates the defects of the human faculties into Laws of Thought; they become a part of the mind which makes them and is also made up of them. Such distinctions become so familiar to us that we regard the thing signified by them as absolutely fixed and defined. These are some of the illusions from which Hegel delivers us by placing us above ourselves, by teaching us to analyze the growth of “what we are pleased to call our minds,” by reverting to a time when our present distinctions of thought and language had no existence.
Of the great dislike and childish impatience of his system which would be aroused among his opponents, he was fully aware, and would often anticipate the jests which the rest of the world, “in the superfluity of their wits,” were likely to make upon him. Men are annoyed at what puzzles them; they think what they cannot easily understand to be full of danger. Many a sceptic has stood, as he supposed, firmly rooted in the categories of the understanding which Hegel resolves into their original nothingness. For, like Plato, he “leaves no stone unturned” in the intellectual world. Nor can we deny that he is unnecessarily difficult, or that his own mind, like that of all metaphysicians, was too much under the dominion of his system and unable to see beyond: or that the study of philosophy, if made a serious business (compare Republic VII 538), involves grave results to the mind and life of the student. For it may encumber him without enlightening his path; and it may weaken his natural faculties of thought and expression without increasing his philosophical power. The mind easily becomes entangled among abstractions, and loses hold of facts. The glass which is adapted to distant objects takes away the vision of what is near and present to us.
To Hegel, as to the ancient Greek thinkers, philosophy was a religion, a principle of life as well as of knowledge, like the idea of good in the Sixth Book of the Republic, a cause as well as an effect, the source of growth as well as of light. In forms of thought which by most of us are regarded as mere categories, he saw or thought that he saw a gradual revelation of the Divine Being. He would have been said by his opponents to have confused God with the history of philosophy, and to have been incapable of distinguishing ideas from facts. And certainly we can scarcely understand how a deep thinker like Hegel could have hoped to revive or supplant the old traditional faith by an unintelligible abstraction: or how he could have imagined that philosophy consisted only or chiefly in the categories of logic. For abstractions, though combined by him in the notion, seem to be never really concrete; they are a metaphysical anatomy, not a living and thinking substance. Though we are reminded by him again and again that we are gathering up the world in ideas, we feel after all that we have not really spanned the gulf which separates φαινόμενα from ὄντα.
Having in view some of these difficulties, he seeks—and we may follow his example—to make the understanding of his system easier (a) by illustrations, and (b) by pointing out the coincidence of the speculative idea and the historical order of thought.
(a) If we ask how opposites can coexist, we are told that many different qualities inhere in a flower or a tree or in any other concrete object, and that any conception of space or matter or time involves the two contradictory attributes of divisibility and continuousness. We may ponder over the thought of number, reminding ourselves that every unit both implies and denies the existence of every other, and that the one is many—a sum of fractions, and the many one—a sum of units. We may be reminded that in nature there is a centripetal as well as a centrifugal force, a regulator as well as a spring,
