Its unity ideal and discoverable only by steady thought.
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 truth. The imaginative parsimony and discipline which such a theory involves are balanced by the immense extension and certitude it gives to knowledge. It is at once an act of allegiance to nature and a Magna Charta which mind imposes on the tyrannous world, which in turn pledges itself before the assembled faculties of man not to exceed its constitutional privilege and to harbour no magic monsters in unattainable lairs from which they might issue to disturb human labours. Yet that spontaneous intelligence which first enabled men to make this genial discovery and take so fundamental a step toward taming experience should not be laid by after this first victory; it is a weapon needed in many subsequent conflicts. To conceive that all nature makes one system is only a beginning: the articulation of natural life has still to be discovered in detail and, what is more, a similar articulation has to be given to the psychic world which now, by the very act that constitutes Nature and makes her consistent, appears at her side or rather in her bosom.
That the unification of nature is eventual and theoretical is a point useful to remember: else the relation of the natural world to poetry, metaphysics, and religion will never become intelligible. Lalande, or whoever it was, who searched the heavens with his telescope and could find no God, would not have found the human mind if he had searched the brain with a microscope. Yet God existed in man's apprehension long before mathematics or even, perhaps, before the vault of heaven; for the objectification of the whole mind, with its passions and motives, naturally precedes that abstraction by which the idea of a material world is drawn from the chaos of experience, an abstraction which culminates in such atomic and astronomical theories as science is now familiar with. The sense for life in things, be they small or great, is not derived from the abstract idea of their bodies but is an ancient concomitant to that idea, inseparable from it until it became abstract. Truth and materiality, mechanism and ideal interests, are collateral projections from one rolling experience, which shows up one aspect or the other as it develops various functions and dominates itself to various ends. When one ore is abstracted and purified, the residuum subsists in that primeval quarry in which it originally lay. The failure to find God among the stars, or even the attempt to find him there, does not indicate that human experience affords no avenue to the idea of God—for history proves the contrary—but indicates rather the atrophy in this particular man of the imaginative faculty by which his race had attained to that idea. Such an atrophy might indeed become general, and God would in that case disappear from human experience as music would disappear if universal deafness attacked the race. Such an event is made conceivable by the loss of allied imaginative habits, which is observable in historic times. Yet possible variations in human faculty do not involve the illegitimacy of such faculties as actually subsist; and the abstract world known to science, unless it dries up the ancient fountains of ideation by its habitual presence in thought, does not remove those parallel dramatisations or abstractions which experience may have suggested to men.
What enables men to perceive the unity of nature is the unification of their own wills. A man half-asleep, without fixed purposes, without intellectual keenness or joy in recognition, might graze about like an animal, forgetting each satisfaction in the next and banishing from his frivolous mind the memory of every sorrow; what had just failed to kill him would leave him as thoughtless and unconcerned as if it had never crossed his path. Such irrational elasticity and innocent improvidence would never put two and two together. Every morning there would be a new world with the same fool to live in it. But let some sobering passion, some serious interest, lend perspective to the mind, and a point of reference will immediately be given for protracted observation; then the laws of nature will begin to dawn upon thought. Every experiment will become a lesson, every event will be remembered as favourable or unfavourable to the master-passion. At first, indeed, this keen observation will probably be animistic and the laws discovered will be chiefly habits, human or divine, special favours or envious punishments and warnings. But the same constancy of aim which discovers the dramatic conflicts composing society, and tries to read nature in terms of passion, will, if it be long sustained, discover behind this glorious chaos a deeper mechanical order. Men's thoughts, like the weather, are not so arbitrary as they seem and the true master in observation, the man guided by a steadfast and superior purpose, will see them revolving about their centres in obedience to quite calculable instincts, and the principle of all their flutterings will not be hidden from his eyes. Belief in indeterminism is a sign of indetermination. No commanding or steady intellect flirts with so miserable a possibility, which in so far as it actually prevailed would make virtue impotent and experience, in its pregnant sense, impossible.
Mind the erratic residue of existence.
We have said that those objects which cannot be incorporated into the one space which the understanding envisages are relegated to another sphere called imagination. We reach here a most important corollary. As material objects, making a single system which fills space and evolves in time, are conceived by abstraction from the flux of sensuous experience, so, pari passu, the rest of experience, with all its other outgrowths and concretions, falls out with the physical world and forms the sphere of mind, the sphere of memory, fancy, and the passions. We have in this discrimination the genesis of mind, not of course in the transcendental sense in which the word mind is extended to mean the sum total and mere fact of existence—for mind, so taken, can have no origin and indeed no specific meaning—but the genesis of mind as a determinate form of being, a distinguishable part of the universe known to experience and discourse, the mind that unravels itself in meditation, inhabits animal bodies, and is studied in psychology.
Mind, in this proper sense of the word, is the residue of existence, the leavings, so to speak, and parings of experience when the material world has been cut out of the whole cloth. Reflection underlines in the chaotic continuum of sense and longing those aspects that have practical significance; it selects the efficacious ingredients in the world. The trustworthy object which is thus retained in thought, the complex of connected events, is nature, and though so intelligible an object is not soon nor vulgarly recognised, because human reflection is perturbed and halting, yet every forward step in scientific and practical knowledge is a step toward its clearer definition. At first much parasitic matter clings to that dynamic skeleton. Nature is drawn like a sponge heavy and dripping from the waters of sentience. It is soaked with inefficacious passions and overlaid with idle accretions. Nature, in a word, is at first conceived mythically, dramatically, and retains much of the unintelligible, sporadic habit of animal experience itself. But as attention awakes and discrimination, practically inspired, grows firm and stable, irrelevant qualities are stripped off, and the mechanical process, the efficacious infallible order, is clearly disclosed beneath. Meantime the incidental effects, the "secondary qualities," are relegated to a personal inconsequential region; they constitute the realm
