them, and because it finds in its own mechanism corresponding sequences of thought. It was the work of a great German metaphysician towards the close of the last century to discriminate and define, more systematically than had been done before, some at least of those higher elements of thought which, over and above the mere perception of external things, the mind thus contributes out of its own structure to the fabric of knowledge. In doing this he did immortal service-proving that when men talked of "experience being the source of knowledge, they forgot that the whole process of experience presupposes the action of innate laws of thought, without which experience can neither gather its facts nor reach their interpretation. Experience," as Kant most truly said, is nothing but a synthesis of intuitions -a building up or putting together of conceptions which the access of external nature finds ready to be awakened in the mind. The whole of this process is determined by the mind's own lawsa process in which even observation of outward facts must take its place according to principles of arrangement in which alone all explanation of them consists, and out of which any understanding of them is impossible. 66 And yet this great fact of a large part of our knowledge and that the most important part-coming to us out of the very furniture and constitution of the mind itself, has been so expressed and presented in the language of philosophy as rather to undermine than to establish our confidence in the certainty of knowledge. For if the mind is so spoken of and represented as to suggest the idea of something apart from the general system of nature, and if its laws of thought are looked upon as "forms "" or moulds into which, by some artificial arrangement or by some mechanical necessity, everything from outside must be squeezed and made to fit then it will naturally occur to us to doubt whether conceptions cut out and manufactured under such conditions can be any trustworthy representation of the truth. Such, unfortunately, has been the mode of representation adopted by many philosophers — and such accordingly has been the result of their teaching. This is the great source of error in every form of the idealistic philosophy, but it is a source of error which can be perfectly eliminated, leaving untouched and undoubted the large body of truths which has made that philosophy attractive to so no many powerful minds. We have only to take care that in expressing those truths we do not use metaphors which are misleading. We have only to remember that we must regard the mind and the laws of its operation in the light of that most assured truth-the unity of nature. The mind has no "moulds"" which have not themselves been moulded on the realities of the universe "forms" which it did not receive as a part and a consequence of a unity with the rest of nature. Its conceptions are not manufactured; they are developed. They are not made; they simply grow. The order of the laws of thought under which it renders intelligible to itself all the phenomena of the universe, is not an order which it invents, but an order which it simply feels and sees. And this "vision and faculty divine" is a necessary consequence of its congenital relations with the whole system of nature-from being bone of its bone, flesh of its flesh-from breathing its atmosphere, from living in its light, and from having with it a thousand points of contact visible and invisible, more than we can number or understand. And yet so subtle are the suggestions of the human spirit in disparagement of its own powers- so near and ever present to us is that region which belongs to the unsatisfied reserve of power that the very fact of our knowledge arising out of our organic relations with the rest of nature has been seized upon as only casting new discredit on all that we seem to know. Because all our knowledge arises out of these relations, therefore, it is said, all our knowledge of things must be itself relative; and relative knowledge is not knowledge of "things in themselves." Such is the argument of metaphysicians an argument repeated with singular unanimity by philosophers of almost every school of thought. By some it has been made the basis of religious proof. By some it has been made the basis of a reasoned scepticism. By others it has been used simply to foil attacks upon belief. The real truth is that it is an argument useless for any purpose whatever, because it is not itself true. The distinction between knowledge of things in their relations, and knowledge of things "in themselves," is a distinction without a meaning. In metaphysics the assertion that we can never attain to any knowl edge of things in themselves does not mean simply that we know things only in a few relations out of many. It does not mean even that there may be and It is a name for something known for that probably are a great many relations which | trated than by quoting the words in which we have not faculties enabling us to con- this favorite doctrine is expressed by Sir ceive. All this is quite true, and a most William Hamilton. Speaking of our important truth. But the metaphysical knowledge of matter he says: distinction is quite different. It affirms that if we knew things in every one of the relations that affect them, we should still be no nearer than before to a knowledge of "things in themselves." "It is proper to observe," says Sir W. Hamilton, "that had we faculties equal in number to all the possible modes of existence, whether of mind or matter, still would our knowledge of mind or matter be only relative. If material existence could exhibit ten thousand phenomena, if we possessed ten thousand senses to apprehend these ten thousand phenomena of material existence, of existence absolutely and in itself we should then be as ignorant as we are at present."* The conception here is that there is something to be known about things in which they are not presented as in any relation to anything else. It affirms that there are certain ultimate entities in nature to which all phenomena are due, and yet which can be thought of as having no relation to these phenomena, or to ourselves, or to any other existence what ever. Now, as the very idea of knowledge consists in the perception of relations, this affirmation is, in the purest sense of the word, nonsense that is to say, it is a series of words which have either no meaning at all or a meaning which is selfcontradictory. It belongs to the class of propositions which throw just discredit on metaphysics mere verbal propositions, pretending to deal with conceptions which are no conceptions at all, but empty sounds. The "unconditioned," we are told, "is unthinkable: " but words which are unthinkable had better be also unspeakable, or at least unspoken. It is altogether untrue that we are compelled to believe in the existence of anything which is "unconditioned" in matter with no qualities - in minds with no character in a God with no attributes. Even the metaphysicians who dwell on this distinction between the relative and It is, however, so important that we the unconditioned admit that it is one to should define to ourselves as clearly as which no idea can be attached. Yet, in we can the nature of the limitations which spite of this admission, they proceed to affect our knowledge, and the real inferfound many inferences upon it, as if it ences which are to be derived from the had an intelligible meaning.

On the contrary, all that except that it must be knowledge of that which has no relation to the mind. There is a sense (and it is the only sense in which the words have any meaning) in which we are all accustomed to say that we know a thing“ in itself," when we have found out, for example, its origin, or its structure, or its chemical composition, as distinguished from its more superficial aspects. If a new substance were offered to us as food, and if we examined its appearance to the eye, and felt its consistency to the touch, and smelt its odor, and finally tasted it, we should then know as much about it as these various senses remains unexplained is the nature and cause of its relations—its relations on the one hand to the elements out of which vegetable vitality has combined it, and its relations on the other hand to the still higher vitality which it threatens to destroy. Its place in the unity of nature is the ultimate object of our search, and this unity is essentially a unity of relations, and of nothing else. That unity everywhere proclaims the truth that there is nothing in the wide universe which is unrelated to the rest. Let us take another example. Until modern science had established its methods of physical investigation, light and sound were known as sensations only. That is to say, they were known in terms of the mental impressions which they immediately produce upon us, and in no other terms whatever. There was no proof that in these sensations we had any knowledge "in themselves" of the external agencies which produce them. But now all this is changed. Science has discovered what these two agencies are "in themselves;" that is to say, it has defined them under aspects which are totally distinct from seeing or hearing, and is able to describe them in terms ad could tell us. Other senses, or other forms of sensation, might soon add their own several contributions to our knowledge, and we might discover that this substance had deleterious effects upon the human organism. This would be knowing, perhaps, by far the most important things that are to be known about it. But we should certainly like to know more, and we should probably consider that we had found out what it was "in itself," when we had discovered farther, for example, that it was the fruit of a tree. Chemistry might next inform us of the analysis of the fruit, and might exhibit some alkaloid to which its peculiar prop-dressed to wholly different faculties of erties and its peculiar effects upon the body are due. This, again, we should certainly consider as knowing what it is "in itself." But other questions respecting it would remain behind. How the tree can extract this alkaloid from the inorganic elements of the soil, and how, when so extracted, it should have such and such peculiar effects upon the animal body, these, and similar questions, we may ask, and probably we shall ask in vain. But there is nothing in the inaccessibility of this knowledge to suggest that we are absolutely incapable of understanding the answer if it were explained to us. On the contrary, the disposition we have to put such questions raises a strong presumption that the answer would be one capable of that assimilation by our intellectual nature in which all understanding of anything consists. There is nothing in the series of phenomena which this substance has exhibited to us nothing in the question which they raise - which can even suggest the idea that all these relations which we have traced, or any others which may remain behind, are the result of something which are conception.

If the universe or any part of it is ever to be really understood by us-if any thing in the nature of an explanation is ever to be reached concerning the system of things in which we live, these are the perceptive powers to which the information must be given — these are the faculties to which the explanation must be addressed. When we desire to know the nature of things "in themselves," we desire to know the highest of their relations which are conceivable to us: we desire, in the words of Bishop Butler, to know "the Author, the cause, and the end of them.”* * Sermon "On the Ignorance of Man," you still; that pompous Miss Ellis and the colonel, and the silent younger sister and the delightful old lady; and I wonder if you, too, are in your usual corner, where I can see you as plainly as I can see mamma in her chair on the terrace opposite.
