No doubt Aristotle and the scholastics were often uncritical. They were too intent on building up and buttressing their system on the broad human or religious foundations which they had chosen for it. They nursed the comfortable conviction that whatever their thought contained was eternal and objective truth, a copy of the divine intellect or of the world's intelligible structure. A sceptic may easily deride that confidence of theirs; their system may have been their system and nothing more. But the way to proceed if we wish to turn our shrewd suspicions and our sense of insecurity into an articulate conviction and to prove that they erred, is to build another system, a more modest one, perhaps, which will grow more spontaneously and inevitably in the mind out of the data of experience. Obviously the rival and critical theory will make the same tacit claim as the other to absolute validity. If all our ideas and perceptions conspire to reinforce the new hypothesis, this will become inevitable and necessary to us. We shall then condemn the other hypothesis, not indeed for having been a hypothesis, which is the common fate of all rational and interpretative thought, but for having been a hypothesis artificial, misleading, and false; one not following necessarily nor intelligibly out of the facts, nor leading to a satisfactory reaction upon them, either in contemplation or in practice.
Now this is in truth exactly the conviction which those malicious psychologists secretly harboured. Their critical scruples and transcendental qualms covered a robust rebellion against being fooled by authority. They rose to abate abuses among which, as Hobbes said, "the frequency of insignificant speech is one." Their psychology was not merely a cathartic, but a gospel. Their young criticism was sent into the world to make straight the path of a new positivism, as now, in its old age, it is invoked to keep open the door to superstition. Some of those reformers, like Hobbes and Locke, had at heart the interests of a physical and political mechanism, which they wished to substitute for the cumbrous and irritating constraints of tradition. Their criticism stopped at the frontiers of their practical discontent; they did not care to ask how the belief in matter, space, motion, God, or whatever else still retained their allegiance, could withstand the kind of psychology which, as they conceived, had done away with individual essences and nominal powers. Berkeley, whose interests lay in a different quarter, used the same critical method in support of a different dogmatism; armed with the traditional pietistic theory of Providence he undertook with a light heart to demolish the whole edifice which reason and science had built upon spatial perception. He wished the lay intellect to revert to a pious idiocy in the presence of Nature, lest consideration of her history and laws should breed "mathematical atheists"; and the outer world being thus reduced to a sensuous dream and to the blur of immediate feeling, intelligence and practical faith would be more unremittingly employed upon Christian mythology. Men would be bound to it by a necessary allegiance, there being no longer any rival object left for serious or intelligent consideration.
The psychological analysis on which these partial or total negations were founded was in a general way admirable; the necessary artifices to which it had recourse in distinguishing simple and complex ideas, principles of association and inference, were nothing but premonitions of what a physiological psychology would do in referring the mental process to its organic and external supports; for experience has no other divisions than those it creates in itself by distinguishing its objects and its organs. Reference to external conditions, though seldom explicit in these writers, who imagined they could appeal to an introspection not revealing the external world, was pervasive in them; as, for instance, where Hume made his fundamental distinction between impressions and ideas, where the discrimination was based nominally on relative vividness and priority in time, but really on causation respectively by outer objects or by spontaneous processes in the brain.
Hume it was who carried this psychological analysis to its goal, giving it greater simplicity and universal scope; and he had also the further advantage of not nursing any metaphysical changeling of his own to substitute for the legitimate offspring of human understanding. His curiosity was purer and his scepticism more impartial, so that he laid bare the natural habits and necessary fictions of thought with singular lucidity, and sufficient accuracy for general purposes. But the malice of a psychology intended as a weapon against superstition here recoils on science itself. Hume, like Berkeley, was extremely young, scarce five-and-twenty, when he wrote his most incisive work; he was not ready to propose in theory that test of ideas by their utility which in practice he and the whole English school have instinctively adopted. An ulterior test of validity would not have seemed to him satisfactory, for though inclined to rebellion and positivism he was still the pupil of that mythical philosophy which attributed the value of things to their origin rather than to their uses, because it had first, in its parabolic way, erected the highest good into a First Cause. Still breathing, in spite of himself, this atmosphere of materialised Platonism, Hume could not discover the true origin of anything without imagining that he had destroyed its value. A natural child meant for him an illegitimate one; his philosophy had not yet reached the wisdom of that French lady who asked if all children were not natural. The outcome of his psychology and criticism seemed accordingly to be an inhibition of reason; he was left free to choose between the distractions of backgammon and "sitting down in a forlorn scepticism."
In his first youth, while disintegrating reflection still overpowered the active interests of his mind, Hume seems to have had some moments of genuine suspense and doubt: but with years and prosperity the normal habits of inference which he had so acutely analysed asserted themselves in his own person and he yielded to the "tendency to feign" so far at least as to believe languidly in the histories he wrote, the compliments he received, and the succulent dinners he devoured. There is a kind of courtesy in scepticism. It would be an offence against polite conventions to press our doubts too far and question the permanence of our estates, our neighbours' independent existence, or even the justification of a good bishop's faith and income. Against metaphysicians, and even against bishops, sarcasm was not without its savour; but the line must be drawn somewhere by a gentleman and a man of the world. Hume found no obstacle in his speculations to the adoption of all necessary and useful conceptions in the sphere to which he limited his mature interests. That he never extended this liberty to believe into more speculative and comprehensive regions was due simply to a voluntary superficiality in his thought. Had he been interested in the rationality of things he would have laboured to discover it, as he laboured to discover that historical truth or that political utility to which his interests happened to attach.
Kant, like Berkeley, had a private mysticism in reserve to raise upon the ruins of science and common-sense. Knowledge was to be removed to make way for faith. This task is ambiguous, and the equivocation involved in it is perhaps the deepest of those confusions with which German metaphysics has since struggled, and which have made it waver between the deepest introspection and the dreariest mythology. To substitute faith for knowledge might mean to teach the intellect humility, to make it aware of its theoretic and transitive function as a faculty for hypothesis and rational fiction, building a bridge of methodical inferences and ideal unities between fact and fact, between endeavour and satisfaction. It might be to remind us, sprinkling over us, as it were, the Lenten ashes of an intellectual contrition, that our thoughts are air even as our bodies are dust, momentary vehicles and products of an immortal vitality in God and in nature, which fosters and illumines us for a moment before it lapses into other forms.
Had Kant proposed to humble and concentrate into a practical faith the same natural ideas which had previously been taken for absolute knowledge, his intention would have been innocent, his conclusions wise, and his analysis free from venom and arrière-pensée. Man, because of his finite and propulsive nature and because he is a pilgrim and a traveller throughout his life, is obliged to have faith: the absent, the hidden, the eventual, is the necessary object of his concern. But what else shall his faith rest in except in what the necessary forms of his perception present to him and what the indispensable categories of his understanding help him to conceive? What possible objects are there for faith except objects of a possible experience? What else should a practical and moral philosophy concern itself with, except the governance and betterment of the real world? It is surely by using his only possible forms of perception and his inevitable categories of understanding that man may yet learn, as he has partly learned already, to live and prosper in the universe. Had Kant's criticism amounted simply to such a confession of the tentative, practical, and hypothetical nature of human reason, it would have been wholly acceptable to the wise; and its appeal to faith would have been nothing but an expression of natural vitality and courage, just as its criticism of knowledge would have been nothing but a better acquaintance with self. This faith would have called the forces of impulse and passion to reason's support, not to its betrayal. Faith would have meant faith in the intellect, a faith naturally expressing man's practical and ideal nature, and the only faith yet sanctioned by its fruits.
Side by side with this reinstatement of reason, however, which was not absent from Kant's system in its critical phase and in its application to science, there lurked in his substitution of faith for knowledge another and sinister intention. He wished to blast as insignificant, because "subjective," the whole structure of human intelligence, with all the
