The same conflict of real and unreal was shown to be essential to every natural life. As long as anything grows it neither completely attains, nor completely falls away from its ideal. The growing acorn is not an oak tree, and yet it is not a mere acorn. The child is not the man; and yet the man is in the child, and only needs to be evolved by interaction with circumstances. The process of growth is one wherein the ideal is always present, as a reconstructive power gradually changing its whole vehicle, or organism, into a more perfect expression of itself. The ideal is reached in the end, just because it is present in the beginning; and there is no end as long as growth continues.

Now, it is evident that knowledge, whether it be that of the individual man or of the human race, is a thing that grows. The process by means of which natural science makes progress, or by which the consciousness of the child expands and deepens into the consciousness of the man, is best made intelligible from the point of view of evolution. It is like an organic process, in which each new acquirement finds its place in an old order, each new fact is brought under the permanent principles of experience, and absorbed into an intellectual life, which itself, in turn, grows richer and fuller with every new acquisition. No knowledge worthy of the name is an aggregation of facts. Wisdom comes by growth.

Hence, the assertion that knowledge never attains reality, does not imply that it always misses it. In morals we do not say that a man is entirely evil, although he never, even in his best actions, attains the true good. And if the process of knowing is one that presses onward towards an ideal, that ideal is never completely missed even in the poorest knowledge. If it grows, the method of fixed alternatives must be inapplicable to it. The ideal, whatever it may be, must be considered as active in the present, guiding the whole movement, and gradually manifesting itself in each of the passing forms, which are used up as the raw material of new acquirement; and yet no passing form completely expresses the ideal.

Nor is it difficult to say what that ideal of knowlege is, although we cannot define it in any adequate manner. We know that the end of morality is the summum bonum, although we cannot, as long as we are progressive, define its whole content, or find it fully realized in any action. Every failure brings new truth, every higher grade of moral character reveals some new height of goodness to be scaled; the moral ideal acquires definiteness and content as humanity moves upwards. And yet the ideal is not entirely unknown even at the first; even to the most ignorant, it presents itself as a criterion which enables him to distinguish between right and wrong, evil and goodness, and which guides his practical life. The same truth holds with regard to knowledge. Its growth receives its impulse from, and is directed and determined by, what is conceived as the real world of facts. This truth, namely, that the ideal knowledge is knowledge of reality, the most subjective philosopher cannot but acknowledge. It is implied in his condemnation of knowledge as merely phenomenal, that there is possible a knowledge of real being. That thought and reality can be brought together, or rather, that they are always together, is presupposed in all knowledge and in all experience. The effort to know is the effort to explain the relation of thought and reality, not to create it. The ideal of perfect knowledge is present from the first; it generates the effort, directs it, distinguishes between truth and error. And that which man ever aims at, whether in the ordinary activities of daily thought, or through the patient labour of scientific investigation, or in the reflective self-torture of philosophic thought, is to know the world as it is. No failure damps the ardour of this endeavour. Relativists, phenomenalists, agnostics, sceptics, Kantians or Neo-Kantians—all the crowd of thinkers who cry down the human intellect, and draw a charmed circle around reality so as to make it unapproachable to the mind of man—ply this useless labour. They are seeking to penetrate beneath the shows of sense and the outer husk of phenomena to the truth, which is the meeting-point of knowledge and reality; they are endeavouring to translate into an intellectual possession the powers that play within and around them; or, in other words, to make these powers express themselves in their thoughts, and supply the content of their spiritual life. The irony, latent in their endeavour, gives them no pause; they are in some way content to pursue what they call phantoms, and to try to satisfy their thirst with the waters of a mirage. This comes from the presence of the ideal within them, that is, of the implicit unity of reality and thought, which seeks for explicit and complete manifestation in knowledge. The reality is present in them as thinking activity, working towards complete revelation of itself by means of knowledge. And its presence is real, although the process is never complete.

In knowledge, as in morals, it is necessary to remember both of the truths implied in the pursuit of an ideal—that a growing thing not only always fails to attain, but also always succeeds. The distinction between truth and error in knowledge is present at every stage in the effort to attain truth, as the distinction between right and wrong is present in every phase of the moral life. It is the source of the intellectual effort. But that distinction cannot be drawn except by reference to a criterion of truth, which condemns our actual knowledge; as it is the absolute good, which condemns the present character. The ideal may be indefinite, and its content confused and poor; but it is always sufficient for its purpose, always better than the actual achievement. And, in this sense, reality, the truth, the veritable being of things, is always reached by the poorest knowledge. As there is no starved and distorted sapling which is not the embodiment of the principle of natural life, so the meanest character is the product of an ideal of goodness, and the most confused opinion of ignorant mankind is an expression of the reality of things. Without it there would not be even the semblance of knowledge, not even error and untruth.

Those who, like Browning, make a division between man's thought and real things, and regard the sphere of knowledge as touching at no point the sphere of actual existence, are attributing to the bare human intellect much more power than it has. They regard mind as creating its phenomenal knowledge, or the apparent world. For, having separated mind from reality, it is evident that they cannot avail themselves of any doctrine of sensations or impressions as a medium between them, or postulate any other form of connection or means of communication. Connection of any kind must, in the end, imply some community of nature, and must put the unity of thought and being—here denied—beneath their difference. Hence, the world of phenomena which we know, and which as known, does not seem to consist of realities, must be the product of the unaided human mind. The intellect, isolated from all real being, has manufactured the apparent universe, in all its endless wealth. It is a creative intellect, although it can only create illusions. It evolves all its products from itself.

But thought, set to revolve upon its own axis in an empty region, can produce nothing, not even illusions. And, indeed, those who deny that it is possible for thought and reality to meet in a unity, have, notwithstanding, to bring over "something" to the aid of thought. There must be some effluence from the world of reality, some manifestations of the thing (though they are not the reality of the thing, nor any part of the reality, nor connected with the reality!) to assist the mind and supply it with data. The "phenomenal world" is a hybrid, generated by thought and "something"—which yet is not reality; for the real world is a world of things in themselves, altogether beyond thought. By bringing in these data, it is virtually admitted that the human mind reaches down into itself in vain for a world, even for a phenomenal one.

Thought apart from things is quite empty, just as things apart from thought are blind. Such thought and such reality are mere abstractions, hypostasized by false metaphysics; they are elements of truth rent asunder, and destroyed in the rending. The dependence of the intelligence of man upon reality is direct and complete. The foolishest dream, that ever played out its panorama beneath a night-cap, came through the gates of the senses from the actual world. Man is limited to his material in all that he knows, just as he is ruled by the laws of thought. He cannot go one step beyond it. To transcend "experience" is impossible. We have no wings to sustain us in an empty region, and no need of any. It is as impossible for man to create new ideas, as it is for him to create new atoms. Our thought is essentially connected with reality. There is no mauvais pas from thought to things. We do not need to leap out of ourselves in order to get into the world. We are in it from the first, both as physical and moral agents, and as thinking beings. Our thoughts are expressions of the real nature of things, so far as they go. They may be and are imperfect; they may be and are confused and inadequate, and express only the superficial aspects and not "the inmost fibres"; still, they are what they are, in virtue of "the reality," which finds itself interpreted in them. Severed from that reality, they would be nothing.

Thus, the distinction between thought and reality is a distinction within a deeper unity. And that unity must not be regarded as something additional to both, or as a third something. It is their unity. It is both reality and thought: it is existing thought, or reality knowing itself and existing through its knowledge of self; it is self-consciousness. The distinguished elements have no existence or meaning except in their unity. Like the actual and ideal, they have significance and being, only in their reference to each other.

There is one more difficulty connected with this matter which I must touch upon, although the discussion may already be regarded as prolix. It is acknowledged by every one that the knowledge of the individual, and his apparent world of realities, grow pari passu. Beyond his sphere of knowledge there is no reality for him, not even apparent reality. But, on the other hand, the real world of existing things exists all the same whether he knows it or not. It did not begin to be with any knowledge he may have of it, it does not cease to be with his extinction, and it is not in any way affected by his valid, or invalid, reconstruction of it in thought. The world which depends on his thought is his world, and not the world of really existing things. And this is true alike of every individual. The world is independent of all human minds. It existed before them, and will, very possibly, exist after them. Can we not, therefore, conclude that the real world is independent of thought, and that it exists without relation to it?
