The Life of Reason: The Phases of Human Progress. George Santayana

he can investigate its origin and describe its relation to other disparate phenomena. The mathematician develops the import of given ideas; the psychologist investigates their origin and describes their relation to the rest of human experience. So the prophet develops the import of his trance, and the theologian the import of the prophecy: which prevents not the historian from coming later and showing the origin, the growth, and the possible function of that maniacal sort of wisdom. True, the theologian commonly dreads a critic more than does the geometer, but this happens only because the theologian has probably not developed the import of his facts with any austerity or clearness, but has distorted that ideal interpretation with all sorts of concessions and side-glances at other tenets to which he is already pledged, so that he justly fears, when his methods are exposed, that the religious heart will be alienated from him and his conclusions be left with no foothold in human nature. If he had not been guilty of such misrepresentation, no history or criticism that reviewed his construction would do anything but recommend it to all those who found in themselves the primary religious facts and religious faculties which that construction had faithfully interpreted in its ideal deductions and extensions. All who perceived the facts would thus learn their import; and theology would reveal to the soul her natural religion, just as Euclid reveals to architects and navigators the structure of natural space, so that they value his demonstrations not only for their hypothetical cogency but for their practical relevance and truth.

      Logic dependent on fact for its importance,

      Now, like the geometer and ingenuous theologian that he was, Plato developed the import of moral and logical experience. Even his followers, though they might give rein to narrower and more fantastic enthusiasms, often unveiled secrets, hidden in the oracular intent of the heart, which might never have been disclosed but for their lessons. But with a zeal unbecoming so well grounded a philosophy they turned their backs upon the rest of wisdom, they disparaged the evidence of sense, they grew hot against the ultimate practical sanctions furnished by impulse and pleasure, they proscribed beauty in art (where Plato had proscribed chiefly what to a fine sensibility is meretricious ugliness), and in a word they sought to abolish all human activities other than the one pre-eminent in themselves. In revenge for their hostility the great world has never given them more than a distrustful admiration and, confronted daily by the evident truths they denied, has encouraged itself to forget the truths they asserted. For they had the bias of reflection and man is born to do more than reflect; they attributed reality and validity only to logical ideas, and man finds other objects continually thrusting themselves before his eyes, claiming his affection and controlling his fortunes.

      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.

      and for its subsistence.

      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.

      Reason and docility.

      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.

      Applicable thought and clarified experience.

      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
