To confuse the instrument with its function and the operation with its meaning has been a persistent foible in modern philosophy. It could thus come about that the function of intelligence should be altogether misconceived and in consequence denied, when it was discovered that figments of reason could never become elements of sense but must always remain, as of course they should, ideal and regulative objects, and therefore objects to which a practical and energetic intellect will tend to give the name of realities. Matter is a reality to the practical intellect because it is a necessary and ideal term in the mastery of experience; while negligible sensations, like dreams, are called illusions by the same authority because, though actual enough while they last, they have no sustained function and no right to practical dominion.
Let us imagine Berkeley addressing himself to that infant or animal consciousness which first used the category of substance and passed from its perceptions to the notion of an independent thing. "Beware, my child," he would have said, "you are taking a dangerous step, one which may hereafter produce a multitude of mathematical atheists, not to speak of cloisterfuls of scholastic triflers. Your ideas can exist only in your mind; if you suffer yourself to imagine them materialised in mid-air and subsisting when you do not perceive them, you will commit a great impiety. If you unthinkingly believe that when you shut your eyes the world continues to exist until you open them again, you will inevitably be hurried into an infinity of metaphysical quibbles about the discrete and the continuous, and you will be so bewildered and deafened by perpetual controversies that the clear light of the gospel will be extinguished in your soul." "But," that tender Peripatetic might answer, "I cannot forget the things about me when I shut my eyes: I know and almost feel their persistent presence, and I always find them again, upon trial, just as they were before, or just in that condition to which the operation of natural causes would have brought them in my absence. If I believe they remain and suffer steady and imperceptible transformation, I know what to expect, and the event does not deceive me; but if I had to resolve upon action before knowing whether the conditions for action were to exist or no, I should never understand what sort of a world I lived in."
"Ah, my child," the good Bishop would reply, "you misunderstand me. You may indeed, nay, you must, live and think as if everything remained independently real. That is part of your education for heaven, which God in his goodness provides for you in this life. He will send into your soul at every moment the impressions needed to verify your necessary hypotheses and support your humble and prudent expectations. Only you must not attribute that constancy to the things themselves which is due to steadfastness in the designs of Providence. Think and act as if a material world existed, but do not for a moment believe it to exist."
With this advice, coming reassuringly from the combined forces of scepticism and religion, we may leave the embryonic mind to its own devices, satisfied that even according to the most malicious psychologists its first step toward the comprehension of experience is one it may congratulate itself on having taken and which, for the present at least, it is not called upon to retrace. The Life of Reason is not concerned with speculation about unthinkable and gratuitous "realities"; it seeks merely to attain those conceptions which are necessary and appropriate to man in his acting and thinking. The first among these, underlying all arts and philosophies alike, is the indispensable conception of permanent external objects, forming in their congeries, shifts, and secret animation the system and life of nature.
When the mind has learned to distinguish external objects and to attribute to them a constant size, shape, and potency, in spite of the variety and intermittence ruling in direct experience, there yet remains a great work to do before attaining a clear, even if superficial, view of the world. An animal's customary habitat may have constant features and their relations in space may be learned by continuous exploration; but probably many other landscapes are also within the range of memory and fancy that stand in no visible relation to the place in which we find ourselves at a given moment. It is true that, at this day, we take it for granted that all real places, as we call them, lie in one space, in which they hold definite geometric relations to one another; and if we have glimpses of any region for which no room can be found in the single map of the universe which astronomy has drawn, we unhesitatingly relegate that region to the land of dreams. Since the Elysian Fields and the Coast of Bohemia have no assignable latitude and longitude, we call these places imaginary, even if in some dream we remember to have visited them and dwelt there with no less sense of reality than in this single and geometrical world of commerce. It belongs to sanity and common-sense, as men now possess them, to admit no countries unknown to geography and filling no part of the conventional space in three dimensions. All our waking experience is understood to go on in some part of this space, and no court of law would admit evidence relating to events in some other sphere.
This principle, axiomatic as it has become, is in no way primitive, since primitive experience is sporadic and introduces us to detached scenes separated by lapses in our senses and attention. These scenes do not hang together in any local contiguity. To construct a chart of the world is a difficult feat of synthetic imagination, not to be performed without speculative boldness and a heroic insensibility to the claims of fancy. Even now most people live without topographical ideas and have no clear conception of the spatial relations that keep together the world in which they move. They feel their daily way about like animals, following a habitual scent, without dominating the range of their instinctive wanderings. Reality is rather a story to them than a system of objects and forces, nor would they think themselves mad if at any time their experience should wander into a fourth dimension. Vague dramatic and moral laws, when they find any casual application, seem to such dreaming minds more notable truths, deeper revelations of efficacious reality, than the mechanical necessities of the case, which they scarcely conceive of; and in this primordial prejudice they are confirmed by superstitious affinities often surviving in their religion and philosophy. In the midst of cities and affairs they are like landsmen at sea, incapable of an intellectual conception of their position: nor have they any complete confidence in their principles of navigation. They know the logarithms by rote merely, and if they reflect are reduced to a stupid wonder and only half believe they are in a known universe or will ever reach an earthly port. It would not require superhuman eloquence in some prophetic passenger to persuade them to throw compass and quadrant overboard and steer enthusiastically for El Dorado. The theory of navigation is essentially as speculative as that of salvation, only it has survived more experiences of the judgment and repeatedly brought those who trust in it to their promised land.
The theory that all real objects and places lie together in one even and homogeneous space, conceived as similar in its constitution to the parts of extension of which we have immediate intuition, is a theory of the greatest practical importance and validity. By its light we carry on all our affairs, and the success of our action while we rely upon it is the best proof of its
