powers of conscience and invention. Sense, on the other hand, is a mere effect, either of body or spirit or of both in conjunction. It gives a vitiated personal view of these realities. Its pleasures are dangerous and unintelligent, and it perishes as it goes.

      Spirit and sense defined by their relation to nature.

      Such are, for primitive apperception, the three great realms of being: nature, sense, and spirit. Their frontiers, however, always remain uncertain. Sense, because it is insignificant when made an object, is long neglected by reflection. No attempt is made to describe its processes or ally them systematically to natural changes. Its illusions, when noticed, are regarded as scandals calculated to foster scepticism. The spiritual world is, on the other hand, a constant theme for poetry and speculation. In the absence of ideal science, it can be conceived only in myths, which are naturally as shifting and self-contradictory as they are persistent. They acquire no fixed character until, in dogmatic religion, they are defined with reference to natural events, foretold or reported. Nature is what first acquires a form and then imparts form to the other spheres. Sense admits definition and distribution only as an effect of nature and spirit only as its principle.

      Vague notions of nature involve vague notions of spirit.

      The form nature acquires is, however, itself vague and uncertain and can ill serve, for long ages, to define the other realms which depend on it for definition. Hence it has been common, for instance, to treat the spiritual as a remote or finer form of the natural. Beyond the moon everything seemed permanent; it was therefore called divine and declared to preside over the rest. The breath that escaped from the lips at death, since it took away with it the spiritual control and miraculous life that had quickened the flesh, was itself the spirit. On the other hand, natural processes have been persistently attributed to spiritual causes, for it was not matter that moved itself but intent that moved it. Thus spirit was barbarously taken for a natural substance and a natural force. It was identified with everything in which it was manifested, so long as no natural causes could be assigned for that operation.

      Sense and spirit the life of nature, which science redistributes but does not deny.

      If the unification of nature were complete sense would evidently fall within it; it is to subtend and sustain the sensible flux that intelligence acknowledges first stray material objects and then their general system. The elements of experience not taken up into the constitution of objects remain attached to them as their life. In the end the dynamic skeleton, without losing its articulation, would be clothed again with its flesh. Suppose my notions of astronomy allowed me to believe that the sun, sinking into the sea, was extinguished every evening, and that what appeared the next morning was his younger brother, hatched in a sun-producing nest to be found in the Eastern regions. My theory would have robbed yesterday's sun of its life and brightness; it would have asserted that during the night no sun existed anywhere; but it would have added the sun's qualities afresh to a matter that did not previously possess them, namely, to the imagined egg that would produce a sun for to-morrow. Suppose we substitute for that astronomy the one that now prevails: we have deprived the single sun—which now exists and spreads its influences without interruption—of its humanity and even of its metaphysical unity. It has become a congeries of chemical substances. The facts revealed to perception have partly changed their locus and been differently deployed throughout nature. Some have become attached to operations in the human brain. Nature has not thereby lost any quality she had ever manifested; these have merely been redistributed so as to secure a more systematic connection between them all. They are the materials of the system, which has been conceived by making existences continuous, whenever this extension of their being was needful to render their recurrences intelligible. Sense, which was formerly regarded as a sad distortion of its objects, now becomes an original and congruent part of nature, from which, as from any other part, the rest of nature might be scientifically inferred.

      Spirit is not less closely attached to nature, although in a different manner. Taken existentially it is a part of sense; taken ideally it is the form or value which nature acquires when viewed from the vantage-ground of any interest. Individual objects are recognisable for a time not because the flux is materially arrested but because it somewhere circulates in a fashion which awakens an interest and brings different parts of the surrounding process into definable and prolonged relations with that interest. Particular objects may perish yet others may continue, like the series of suns imagined by Heraclitus, to perform the same office. The function will outlast the particular organ. That interest in reference to which the function is defined will essentially determine a perfect world of responsive extensions and conditions. These ideals will be a spiritual reality; and they will be expressed in nature in so far as nature supports that regulative interest. Many a perfect and eternal realm, merely potential in existence but definite in constitution, will thus subtend nature and be what a rational philosophy might call the ideal. What is called spirit would be the ideal in so far as it obtained expression in nature; and the power attributed to spirit would be the part of nature's fertility by which such expression was secured.

CHAPTER VI—DISCOVERY OF FELLOW-MINDS

      Another background for current experience may be found in alien minds.

      When a ghostly sphere, containing memory and all ideas, has been distinguished from the material world, it tends to grow at the expense of the latter, until nature is finally reduced to a mathematical skeleton. This skeleton itself, but for the need of a bridge to connect calculably episode with episode in experience, might be transferred to mind and identified with the scientific thought in which it is represented. But a scientific theory inhabiting a few scattered moments of life cannot connect those episodes among which it is itself the last and the least substantial; nor would such a notion have occurred even to the most reckless sceptic, had the world not possessed another sort of reputed reality—the minds of others—which could serve, even after the supposed extinction of the physical world, to constitute an independent order and to absorb the potentialities of being when immediate consciousness nodded. But other men's minds, being themselves precarious and ineffectual, would never have seemed a possible substitute for nature, to be in her stead the background and intelligible object of experience. Something constant, omnipresent, infinitely fertile is needed to support and connect the given chaos. Just these properties, however, are actually attributed to one of the minds supposed to confront the thinker, namely, the mind of God. The divine mind has therefore always constituted in philosophy either the alternative to nature or her other name: it is par excellence the seat of all potentiality and, as Spinoza said, the refuge of all ignorance.

      Speculative problems would be greatly clarified, and what is genuine in them would be more easily distinguished from what is artificial, if we could gather together again the original sources for the belief in separate minds and compare these sources with those we have already assigned to the conception of nature. But speculative problems are not alone concerned, for in all social life we envisage fellow-creatures conceived to share the same thoughts and passions and to be similarly affected by events. What is the basis of this conviction? What are the forms it takes, and in what sense is it a part or an expression of reason?

      This question is difficult, and in broaching it we cannot expect much aid from what philosophers have hitherto said on the subject. For the most part, indeed, they have said nothing, as by nature's kindly disposition most questions which it is beyond a man's power to answer do not occur to him at all. The suggestions which have actually been made in the matter may be reduced to two: first, that we conceive other men's minds by projecting into their bodies those feelings which we immediately perceive to accompany similar operations in ourselves, that is, we infer alien minds by analogy; and second, that we are immediately aware of them and feel them to be friendly or hostile counterparts of our own thinking and effort, that is, we evoke them by dramatic imagination.

      Two usual accounts of this conception criticised:

      analogy between bodies,

      The first suggestion has the advantage that it escapes solipsism by a reasonable argument, provided the existence of the material
