The technical terms which abound in philosophical works are useful in the exposition of a system, but rather the reverse for those who are striving to grasp its salient features; for understanding these terms partially only, or not understanding them at all, they are tempted to imagine that they take in the meaning; this leads to vague notions being entertained on a subject which is nevertheless earnestly studied. Generally I abstain from the use of esoteric terms, but Kant having coined fresh ones to express his ideas it behoves us to use his own formula. To paraphrase them so as to render them intelligible without multiplying them might only further obscure the sense, and yet, on the other hand, to enter freely into further developments would require a volume, and the end would be better served by going direct to Kant’s work. Hence the embarrassment I feel on approaching the subject.

Kant’s Teaching.

Kant undertook a work which no one before him had attempted. Instead of criticising, as was then the fashion, the result of our knowledge, whether in religion or in history, or science, he shut his eyes resolutely to all that philosophy, whether sensualistic or spiritualistic asserted as true, and making Descartes his starting point he boldly went to the root of the matter; he questioned whether human reason had the power of perceiving the truth, and in cases where this power existed—but with limits—he sought to discover why these limits existed. He therefore resolved to subject reason itself to his searching analysis, and thus to assist, as it were, at the birth of thought. He accomplished this extraordinary task with an ease of which no one previously would have been capable.

The world is governed by immutable laws, and the human race is subject to them. Kant gives an account of those which it must necessarily obey in order to pass from a passive “mirror” into a conscious mind.

Sensation.

In any material object I may seek to obtain, such as a table, my interests are concentrated in the table itself, not on the tools which the workman has used in its manufacture; but if it were a question of thought, then the means by which it was produced by the human mind engage us; and these means, of course, consist in the proper use of the instruments at man’s disposal.

That which was at the origin of mankind is repeated at the birth of every human being; he comes into the world in a lethargic condition, but endowed with latent instincts which we name in one word, sense; common to man and to animals, it places them in relationship with the things exterior to themselves; this sense, or capability of sensation, is merely the general faculty of feeling. No newly-born child would emerge from its torpor if it were not surrounded by material objects which affirm their presence by reacting on him; his first act, at the moment when he perceives his surroundings is the transference of his own mind, until now isolated in itself alone, towards the objects which solicit his attention.

The sense which operates in each child is inward, we name it briefly—sensation—to distinguish it from the five external senses, which are more familiar to us, since even at school their functions and modes of action have been explained to us.

For instance, we know that it is only necessary to touch the strings of an instrument to cause them to vibrate, the vibrations are communicated to the air, and are then called waves of sound; they diffuse themselves with an incredible swiftness in space, advancing and retreating in the manner of the waves of the sea, they reach our ears, touch the auditory nerve, cause the tympanum to vibrate, penetrate to the brain, and give us instantaneously the sensation of sound. And it is to the waves of light passing through the ether, and communicating with the optic nerve of the organ of sight, that we owe the sensation of sight of the objects before us.

The vacant look of a newly-born infant, implies that it has undergone an experience, it has felt something of the nature of a shock; a shock always implies resistance and yielding. In the child it is the human eye becoming conscious of itself amidst the impressions produced on it by the confused sight of external objects, and hearing the noises which occur around him. This instance is analogous to the vibratory movement of the waves described and even drawn in all manuals on physics.
