And now how does this complex structure of logic, metaphysics, psychology, ethics, and politics stand today, after the philosophic storms of a century have beaten down upon it? It is pleasant to answer that much of the great edifice remains; and that the “critical philosophy” represents an event of permanent importance in the history of thought. But many details and outworks of the structure have been shaken.
Kant’s “critical philosophy” has stood up to the test of time. It represents an event of permanent importance in the history of thought.
First, then, is space a mere “form of sensibility,” having no objective reality independent of the perceiving mind? Yes and no. Yes: for space is an empty concept when not filled with perceived objects; “space” merely means that certain objects are, for the perceiving mind, at such and such a position, or distance, with reference to other perceived objects; and no external perception is possible except of objects in space; space then is assuredly a “necessary form of the external sense.” And no: for without doubt, such spatial facts as the annual elliptical circuit of sun by earth, though statable only by a mind, are independent of any perception whatever; the deep and dark blue ocean rolled on before Byron told it to, and after he had ceased to be. Not is space a “construct” of the mind through the coordination of spaceless sensations; we perceive space directly through our simultaneous perception of different objects and various points as when we see an insect moving across a still background. Likewise: time as a sense of before and after, or a measurement of motion, is of course subjective, and highly relative; but a tree will age, wither and decay whether or not the lapse of time is measured or perceived. The truth is that Kant was too anxious to prove the subjectivity of space, as a refuge from materialism; he feared the argument that if space is objective and universal, God must exist in space, and be therefore spatial and material. He might have been content with the critical idealism which shows that all reality is known to us primarily as our sensations and ideas. The old fox bit off more than he could chew. [The persistent vitality of Kant’s theory of knowledge appears in its complete acceptance by so matter-of-fact a scientist as the late Charles P. Steinmetz: “All our sense-perceptions are limited by, and attached to, the conceptions of time and space. Kant, the greatest and most critical of all philosophers, denies that time and space are the product of experience, but shows them to be categories—conceptions in which our minds clothe the sense perceptions. Modern physics has come to the same conclusion in the relativity theory, that absolute space and absolute time have no existence, hut time and space exist only as far as things or events fill them; that is, they are forms of perception.”—Address at the Unitarian Church, Schenectady, 1923.]
Kant relates space to the perceiving mind, and so the objective reality of space can be dependent or independent of perception. But KHTK relates space to the extents of manifestation. In this case, the objective reality of space is not independent of the manifestation. The “emptiness” of space between two objects is a part of the manifestation.
Similarly, Kant relates time to the perceiving mind. But KHTK relates time to the duration of the manifestation. The smaller is the duration the faster is the motion. Therefore, the objective reality of time is not independent of the manifestation either. Neither space nor time exist in the absence of manifestation.
The concept of matter as separate from thought is flawed. Both matter and thought are part of the same spectrum of substance. This spectrum of substance forms the knowable universe as opposed to the Unknowable. God lies in the unknowable realm. All ideas about God are part of thought that belongs to the knowable universe.
He
might well have contented himself, too, with the relativity of scientific
truth, without straining towards that mirage, the absolute. Recent studies like
those of Pearson in England, Mach in Germany, and Henri Poincare in France,
agree rather with Hume than with Kant: all science, even the most rigorous
mathematics, is relative in its truth. Science itself is not worried about the
matter; a high degree of probability contents it. Perhaps, after all,
“necessary” knowledge is not necessary?
All science deals with the knowable (manifested) universe of substance. The substance is manifested as thought, energy and matter. In the background of the knowable universe is the Unknowable. As long as the Unknowable is there, science is not absolute.
The
great achievement of Kant is to have shown, once for all, that the external
world is known to us only as sensation; and that the mind is no mere helpless tabula rasa, the inactive victim of
sensation, but a positive agent, selecting and reconstructing experience as
experience arrives. We can make subtractions from this accomplishment without injuring
its essential greatness. We may smile, with Schopenhauer, at the exact baker’s
dozen of categories, so prettily boxed into triplets, and then stretched and
contracted and interpreted deviously and ruthlessly to fit and surround all
things. [Op. cit., vol. ii, p. 23.] And
we may even question whether these categories, or interpretive forms of
thought, are innate, existing before sensation and experience; perhaps so in
the individual, as Spencer conceded, though acquired by the race; and then,
again, probably acquired even by the individual: the categories may be grooves
of thought, habits of perception and conception, gradually produced by sensations
and perceptions automatically arranging themselves, first in disorderly ways,
then, by a kind of natural selection of forms of arrangement, in orderly and
adaptive and illuminating ways. It is memory that classifies and interprets
sensations into perceptions, and perceptions into ideas; but memory is an
accretion. That unity of the mind which Kant thinks native (the
“transcendental unity of apperception”) is acquired and not by all;
and can be lost as well as won in amnesia, or alternating personality, or
insanity. Concepts are an achievement, not a gift.
It is true that the external world (Unknowable) first manifests as sensations. Sensations upon assimilation become perceptions. Such assimilation is guided by the inherent makeup of the mind, which may be described as a set of postulates. Reason applied to perceptions then generates further considerations, ideas, etc. Underlying this assimilation and reasoning is the active Principle of Oneness. Any violation of the Principle of Oneness generates anomalies.
Kant contributed much to this understanding. He describes the postulates referenced above as categories. The development of these categories is assisted by the Principle of Oneness. This Principle of Oneness fills in what was left out by Kant.
The
nineteenth century dealt rather hardly with Kant’s ethics, his theory of an
innate, a priori, absolute moral sense. The philosophy of evolution suggested
irresistibly that the sense of duty is a social deposit in the individual, the
content of conscience is acquired, though the vague disposition to social
behavior is innate. The moral self, the social man, is no “special
creation” coming mysteriously from the hand of God, but the late product
of a leisurely evolution. Morals are not absolute; they are a code of conduct
more or less haphazardly developed for group survival, and varying with the
nature and circumstances of the group: a people hemmed in by enemies, for
example, will consider as immoral that zestful and restless individualism which
a nation youthful and secure in its wealth and isolation will condone as a
necessary ingredient in the exploitation of natural resources and the formation
of national character. No action is good in itself, as Kant supposes. [Practical Reason, p. 31.]
Kant’s theory of an innate and absolute moral sense has mostly been ignored. Instead the theory of evolution has been favored, according to which the sense of duty is mostly acquired through social conditions. No action is good in itself, as Kant supposes. This anomaly is resolved when one accepts the Principle of Oneness as the ultimate criterion.
His pietistic youth, and his hard life of endless duty and infrequent pleasure, gave him a moralistic bent; he came at last to advocate duty for duty’s sake, and so fell unwittingly into the arms of Prussian absolutism. [Cf. Prof. Dewey: German Philosophy and Politics.] There is something of a severe Scotch Calvinism in this opposition of duty to happiness; Kant continues Luther and the Stoic Reformation, as Voltaire continues Montaigne and the Epicurean Renaissance. He represented a stern reaction against the egoism and hedonism in which Helvetius and Holbach had formulated the life of their reckless era, very much as Luther had reacted against the luxury and laxity of Mediterranean Italy. But after a century of reaction against the absolutism of Kant’s ethics, we find ourselves again in a welter of urban sensualism and immorality, of ruthless individualism untempered with democratic conscience or aristocratic honor; and perhaps the day will soon come when a disintegrating civilization will welcome again the Kantian call to duty.
Kant’s sense of duty and moralistic bent may be contrasted against the free thinking and happy bent of Voltaire. Again, the apparent anomaly disappears as one accepts the Principle of Oneness as one’s ultimate criterion.
The marvel in Kant’s philosophy is his vigorous revival, in the second Critique, of those religious ideas of God, freedom, and immortality, which the first Critique had apparently destroyed. “In Kant’s works,” says Nietzsche’s critical friend, Paul Ree, “you feel as though you were at a country fair. You can buy from him anything you want freedom of the will and captivity of the will, idealism, and a refutation of idealism, atheism and the good Lord. Like a juggler out of an empty hat, Kant draws out of the concept of duty a God, immortality, and freedom, to the great surprise of his readers.” [In Untermann, Science and Revolution, Chicago, 1905; p. 81.] Schopenhauer too takes a fling at the derivation of immortality from the need of reward: “Kant’s virtue, which at first bore itself so bravely towards happiness, loses its independence later, and holds out its hand for a tip.” [In Paulsen, p. 317.] The great pessimist believes that Kant was really a sceptic who, having abandoned belief himself, hesitated to destroy the faith of the people, for fear of the consequences to public morals. “Kant discloses the groundlessness of speculative theology, and leaves popular theology untouched, nay even establishes it in a nobler form as a faith based upon moral feeling.” This was afterwards distorted by the philosophasters into rational apprehension and consciousness of God, etc. . . . ; while Kant, as he demolished old and revered errors, and knew the danger of doing so, rather wished through the moral theology merely to substitute a few weak temporary supports, so that the ruin might not fall upon him, but that he might have time to escape.” [The World as Will and Idea, vol. ii, p. 129.] So too Heine, in what is no doubt an intentional caricature, represents Kant, after having destroyed religion, going out for a walk with his servant Lampe, and suddenly perceiving that the old man’s eyes are filled with tears. “Then Immanuel Kant has compassion, and shows that he is not only a great philosopher, but also a good man; and half kindly, half ironically, he speaks: ‘Old Lampe must have a God or else he cannot be happy, says the practical reason; for my part, the practical reason may, then, guarantee the existence of God.’” [Quoted by Paulsen, p. 8.] If these interpretations were true we should have to call the second Critique a Transcendental Anesthetic.
Kant first destroys religion from the viewpoint of reason and then builds it back up from the viewpoint of faith. Thus, he appears self-contradictory. However, as we substitute faith by the Principle of Oneness, it starts to make sense.
But
these adventurous reconstructions of the inner Kant need not be taken too
seriously. The fervor of the essay on ”Religion within the Limits of Pure
Reason” indicates a sincerity too intense to be questioned, and the
attempt to change the base of religion from theology to morals, from creeds to
conduct, could have come only from a profoundly religious mind. “It is
indeed true,” he wrote to Moses Mendelssohn in 1766, “that I think
many things with the clearest conviction, . . . which I never have the courage
to say; but I will never say anything which I do not think.” [In Paulsen, p. 53.] Naturally, a long
and obscure treatise like the great Critique lends itself to rival
interpretations; one of the first reviews of the book, written by Reinhold a
few years after it appeared, said as much as we can say today: “The Critique of Pure Reason has been
proclaimed by the dogmatists as the attempt of a sceptic who undermines the
certainty of all knowledge;—by the sceptics as a piece of arrogant presumption
that undertakes to erect a new form of dogmatism upon the ruins of previous
systems;—by the supernaturalists as a subtly plotted artifice to displace the
historical foundations of religion, and to establish naturalism without
polemic;—by the naturalists as a new prop for the dying philosophy of faith;—by
the materialists as an idealistic contradiction of the reality of matter;—by
the spiritualists as an unjustifiable limitation of all reality to the corporeal
world, concealed under the name of the domain of experience.” [In Paulsen, p. 114,] In truth the glory
of the book lay in its appreciation of all these points of view; and to an
intelligence as keen as Kant’s own, it might well appear that he had really
reconciled them all, and fused them into such a unity of complex truth as
philosophy had not seen in all its history before.
Kant has been criticized alike by dogmatists, skeptics, supernaturalists, naturalists, materialists, and spiritualists. In truth, Kant’s work appreciates all these points of view; and really reconciles them all, and fuses them into a unity of complex truth. The Principle of Oneness makes Kant’s approach much clearer.
As
to his influence, the entire philosophic thought of the nineteenth century
revolved about his speculations. After Kant, all Germany began to talk
metaphysics: Schiller and Goethe studied him; Beethoven quoted with admiration
his famous words about the two wonders of life “the starry heavens above,
the moral law within”; and Fichte, Schelling, Hegel and Schopenhauer
produced in rapid succession great systems of thought reared upon the idealism
of the old Konigsberg sage. It was in these balmy days of German metaphysics that
Jean Paul Richter wrote: “God has given to the French the land, to the
English the sea, to the Germans the empire of the air.” Kant’s criticism
of reason, and his exaltation of feeling, prepared for the voluntarism of
Schopenhauer and Nietzsche, the intuitionism of Bergson, and the pragmatism of
William James; his identification of the laws of thought with the laws of
reality gave to Hegel a whole system of philosophy; and his unknowable
“thing-in-itself” influenced Spencer more than Spencer knew. Much of
the obscurity of Carlyle is traceable to his attempt to allegorize the already
obscure thought of Goethe and Kant that diverse religions and philosophies are
but the changing garments of one eternal truth. Caird and Green and Wallace and
Watson and Bradley and many others in England owe their inspiration to the
first Critique; and even the wildly
innovating Nietzsche takes his epistemology from the “great Chinaman of
Konigsberg” whose static ethics he so excitedly condemns. After a century
of struggle between the idealism of Kant, variously reformed, and the
materialism of the Enlightenment, variously redressed, the victory seems to lie
with Kant. Even the great materialist Helvetius wrote, paradoxically: “Men, if
I may dare say it, are the creators of matter.” [In Chamberlain, vol. i, p. 86.] Philosophy will never again be so
naive as in her earlier and simpler days; she must always be different
hereafter, and profounder, because Kant lived.

Final Comments
Empty space is no less a phenomena than solid objects. The smaller is the duration in terms of time the faster is the motion. Space and time are, therefore, characteristics of the manifested phenomena than the mode of perception as Kant believed. Perception depends on how the sensations are assimilated with the inherent makeup of the mind (the a priori postulates). The criterion for this assimilation is the Principle of Oneness.
Any reasoning arising from the perception, which then results in further considerations of evolution, morality, duty, free will, happiness, faith, etc., resolve nicely when viewed through the Principle of Oneness.
The model of philosophy proposed by Kant has stood the test of time. It is robust. It becomes more robust when the Principle of Oneness is added to it.
