The fact that each spirit was confined to its own perceptions condemned it to an initial subjectivity and agnosticism. What things might exist besides his ideas he could never know. That such things [Pg 55] existed was not doubted; Kant never accepted that amazing principle of dogmatic egotism that nothing is able to exist unless I am able to know it. On the contrary he assumed that human perceptions, with the moral postulates which he added to them, were symbols of a real world of forces or spirits existing beyond. This assumption reduced our initial idiotism to a constitutional taint of our animal minds, not unlike original sin, and excluded that romantic pride and self-sufficiency in which a full-fledged transcendentalism always abounds. To this contrite attitude of Kant's agnosticism his personal character and ethics corresponded. A wizened little old bachelor, a sedentary provincial scribe, scrupulous and punctual, a courteous moralist who would have us treat humanity in the person of another as an end and never merely as a means, a pacifist and humanitarian who so revered the moral sense according to Shaftesbury and Adam Smith that, after having abolished earth and heaven, he was entirely comforted by the sublime truth that nevertheless it remained wrong to tell a lie--such a figure has nothing in it of the officious egotist or the superman. Yet his very love of exactitude and his scruples about knowledge, misled by the psychological fallacy that nothing can be an object of knowledge except some idea in the mind, led him [Pg 56] in the end to subjectivism; while his rigid conscience, left standing in that unnatural void, led him to attribute absoluteness to what he called the categorical imperative. But this void outside and this absolute oracle within are germs of egotism, and germs of the most virulent species. The categorical imperative, or unmistakable voice of conscience, was originally something external enough--too external, indeed, to impose by itself a moral obligation. The thunders of Sinai and the voice from the whirlwind in Job fetched their authority from the suggestion of power; there spoke an overwhelming physical force of which we were the creatures and the playthings, a voice which far from interpreting our sense of justice, or our deepest hopes, threatened to crush and to flout them. If some of its commandments were moral, others were ritual or even barbarous; the only moral sanction common to them all came from our natural prudence and love of life; our wisdom imposed on us the fear of the Lord. The prophets and the gospel did much to identify this external divine authority with the human conscience; an identification which required a very elaborate theory of sin and punishment and of existence in other worlds, since the actual procedure of nature and history can never be squared with any ideal of right.
