The most legitimate constructions of reason soon become merely speculative, soon pass, I mean, beyond the sphere of practical application; and the man of affairs, adjusting himself at every turn to the opaque brutality of fact, loses his respect for the higher reaches of logic and forgets that his recognition of facts themselves is an application of logical principles. In his youth, perhaps, he pursued metaphysics, which are the love-affairs of the understanding; now he is wedded to convention and seeks in the passion he calls business or in the habit he calls duty some substitute for natural happiness. He fears to question the value of his life, having found that such questioning adds nothing to his powers; and he thinks the mariner would die of old age in port who should wait for reason to justify his voyage. Reason is indeed like the sad Iphigenia whom her royal father, the Will, must sacrifice before any wind can fill his sails. The emanation of all things from the One involves not only the incarnation but the crucifixion of the Logos. Reason must be eclipsed by its supposed expressions, and can only shine in a darkness which does not comprehend it. For reason is essentially hypothetical and subsidiary, and can never constitute what it expresses in man, nor what it recognises in nature.
If logic should refuse to make this initial self-sacrifice and to subordinate itself to impulse and fact, it would immediately become irrational and forfeit its own justification. For it exists by virtue of a human impulse and in answer to a human need. To ask a man, in the satisfaction of a metaphysical passion, to forego every other good is to render him fanatical and to shut his eyes daily to the sun in order that he may see better by the star-light. The radical fault of rationalism is not any incidental error committed in its deductions, although such necessarily abound in every human system. Its great original sin is its denial of its own basis and its refusal to occupy its due place in the world, an ignorant fear of being invalidated by its history and dishonoured, as it were, if its ancestry is hinted at. Only bastards should fear that fate, and criticism would indeed be fatal to a bastard philosophy, to one that does not spring from practical reason and has no roots in life. But those products of reason which arise by reflection on fact, and those spontaneous and demonstrable systems of ideas which can be verified in experience, and thus serve to render the facts calculable and articulate, will lose nothing of their lustre by discovering their lineage. So the idea of nature remains true after psychology has analysed its origin, and not only true, but beautiful and beneficent. For unlike many negligible products of speculative fancy it is woven out of recurrent perceptions into a hypothetical cause from which further perceptions can be deduced as they are actually experienced.
Such a mechanism once discovered confirms itself at every breath we draw, and surrounds every object in history and nature with infinite and true suggestions, making it doubly interesting, fruitful, and potent over the mind. The naturalist accordingly welcomes criticism because his constructions, though no less hypothetical and speculative than the idealist's dreams, are such legitimate and fruitful fictions that they are obvious truths. For truth, at the intelligible level where it arises, means not sensible fact, but valid ideation, verified hypothesis, and inevitable, stable inference. If the idealist fears and deprecates any theory of his own origin and function, he is only obeying the instinct of self-preservation; for he knows very well that his past will not bear examination. He is heir to every superstition and by profession an apologist; his deepest vocation is to rescue, by some logical tour de force, what spontaneously he himself would have taken for a consecrated error. Now history and criticism would involve, as he instinctively perceives, the reduction of his doctrines to their pragmatic value, to their ideal significance for real life. But he detests any admission of relativity in his doctrines, all the more because he cannot avow his reasons for detesting it; and zeal, here as in so many cases, becomes the cover and evidence of a bad conscience. Bigotry and craft, with a rhetorical vilification of enemies, then come to reinforce in the prophet that natural limitation of his interests which turns his face away from history and criticism; until his system, in its monstrous unreality and disingenuousness, becomes intolerable, and provokes a general revolt in which too often the truth of it is buried with the error in a common oblivion.
If idealism is intrenched in the very structure of human reason, empiricism represents all those energies of the external universe which, as Spinoza says, must infinitely exceed the energies of man. If meditation breeds science, wisdom comes by disillusion, even on the subject of science itself. Docility to the facts makes the sanity of science. Reason is only half grown and not really distinguishable from imagination so long as she cannot check and recast her own processes wherever they render the moulds of thought unfit for their subject-matter. Docility is, as we have seen, the deepest condition of reason's existence; for if a form of mental synthesis were by chance developed which was incapable of appropriating the data of sense, these data could not be remembered or introduced at all into a growing and cumulative experience. Sensations would leave no memorial; while logical thoughts would play idly, like so many parasites in the mind, and ultimately languish and die of inanition. To be nourished and employed, intelligence must have developed such structure and habits as will enable it to assimilate what food comes in its way; so that the persistence of any intellectual habit is a proof that it has some applicability, however partial, to the facts of sentience.
This applicability, the prerequisite of significant thought, is also its eventual test; and the gathering of new experiences, the consciousness of more and more facts crowding into the memory and demanding co-ordination, is at once the presentation to reason of her legitimate problem and a proof that she is already at work. It is a presentation of her problem, because reason is not a faculty of dreams but a method in living; and by facing the flux of sensations and impulses that constitute mortal life with the gift of ideal construction and the aspiration toward eternal goods, she is only doing her duty and manifesting what she is. To accumulate facts, moreover, is in itself to prove that rational activity is already awakened, because a consciousness of multitudinous accidents diversifying experience involves a wide scope in memory, good methods of classification, and keen senses, so that all working together they may collect many observations. Memory and all its instruments are embodiments, on a modest scale, of rational activities which in theory and speculation reappear upon a higher level. The expansion of the mind in point of retentiveness and wealth of images is as much an advance in knowledge as is its development in point of organisation. The structure may be widened at the base as well as raised toward its ideal summit, and while a mass of information imperfectly digested leaves something still for intelligence to do, it shows at the same time how much intelligence has done already.
The function of reason is to dominate experience; and obviously openness to new impressions is no less necessary to that end than is the possession of principles by which new impressions may be interpreted.
CHAPTER IX—HOW THOUGHT IS PRACTICALNothing is more natural or more congruous with all the analogies of experience than that animals should feel and think. The relation of mind to body, of reason to nature, seems to be actually this: when bodies have reached a certain complexity and vital equilibrium, a sense begins to inhabit them which is focussed upon the preservation of that body and on its reproduction. This sense, as it becomes reflective and expressive of physical welfare, points more and more to its own persistence and harmony, and generates the Life of Reason. Nature is reason's basis and theme; reason is nature's consciousness; and, from the point of view of that consciousness when it has arisen, reason is also nature's justification and goal.
To separate things so closely bound together as are mind and body, reason and nature, is consequently a violent and artificial divorce, and a man of judgment will instinctively discredit any philosophy in which it is decreed. But to avoid divorce it is well first to avoid unnatural unions, and not to attribute to our two elements, which must be partners for life, relations repugnant to their respective natures and offices. Now the body is an instrument, the mind its function, the witness and reward of its operation. Mind is the body's entelechy, a value which accrues to the body when it has reached a certain perfection, of which it would be a pity, so to speak, that it should remain unconscious; so that while the body feeds the mind the mind perfects the body, lifting it and all its natural relations and impulses into the moral world, into the sphere of interests and ideas.
No connection could be closer than this reciprocal involution, as nature and life reveal it; but the connection is natural, not dialectical. The union will be denaturalised and, so far as philosophy goes, actually destroyed, if we seek to carry it on into logical equivalence. If we isolate the terms mind and body and study the inward implications of each apart, we shall never discover the other. That matter cannot, by transposition of its particles, become what we call consciousness, is an admitted truth; that mind cannot become its own occasions or determine its own march, though it be a truth not recognised by all philosophers, is in itself no less obvious. Matter, dialectically studied, makes consciousness seem a superfluous and unaccountable addendum; mind, studied in the same way, makes nature an embarrassing idea, a figment which ought to be subservient to conscious aims and perfectly transparent, but which remains opaque and overwhelming. In order to escape these sophistications, it suffices to revert to immediate observation and state the question in its proper terms: nature lives, and perception is a private echo and response to ambient motions. The soul is the voice of the body's interests; in watching them a man defines the world that sustains him and that conditions all his satisfactions. In discerning his origin he christens Nature by the eloquent name of mother, under which title she enters the universe of discourse. Simultaneously he discerns his own existence and marks off the inner region of his dreams. And it behooves him not to obliterate these discoveries. By trying to give his mind false points of attachment in nature he would disfigure not only nature but also that reason which is so much the essence of his life.
