Note 253 — LECTURE XVI. GOD THE PRINCIPLE OF THE IDEA OF THE GOOD.

On the spirituality of the soul, see all our writings. We will limit ourselves to two citations. 2d Series, vol. iii., lecture 25, p. 859: "It is impossible to know any phenomenon of consciousness, the phenomena of sensation, or volition, or of intelligence, without instantly referring them to a subject one and identical, which is the me; so we cannot know the external phenomena of resistance, of solidity, of impenetrability, of figure, of color, of smell, of taste, etc., without judging that these are not phenomena in appearance, but phenomena which belong to something real, which is solid, impenetrable, figured, colored, odorous, savory, etc. On the other hand, if you did not know any of the phenomena of consciousness, you would never have the least idea of the subject of these phenomena; if you did not know any of the external phenomena of resistance, of solidity, of impenetrability, of figure, of color, etc., you would not have any idea of the subject of these phenomena: therefore the characters, whether of the phenomena of consciousness, or of exterior phenomena, are for you the only signs of the nature of the subjects of these phenomena. In examining the phenomena which fall under the senses, we find between them grave differences upon which it is useless here to insist, and which establish the distinction of primary qualities and of secondary qualities. In the first rank among the primary qualities is solidity, which is given to you in the sensation of resistance, and inevitably accompanied by form, etc. On the contrary, when you examine the phenomena of consciousness, you do not therein find this character of resistance, of solidity, of form, etc.; you do not find that the phenomena of your consciousness have a figure, solidity, impenetrability, resistance; without speaking of secondary qualities which are equally foreign to them, color, savor, sound, smell, etc. Now, as the subject is for us only the collection of the phenomena which reveal it to us, together with its own existence in so far as the subject of the inherence of these phenomena, it follows that, under phenomena marked with dissimilar characters and entirely foreign to each other, the human mind conceives dissimilar and foreign subjects. Thus as solidity and figure have nothing in common with sensation, will, and thought, as every solid is extended for us, and as we place it necessarily in space, while our thoughts, our volitions, our sensations, are for us unextended, and while we cannot conceive them and place them in space, but only in time, the human mind concludes with perfect strictness that the subject of the exterior phenomena has the character of the latter, and that the subject of the phenomena of consciousness has the character of the former; that the one is solid and extended, and that the other is neither solid nor extended. Finally, as that which is solid and extended is divisible, and as that which is neither solid nor extended is indivisible, hence divisibility is attributed to the solid and extended subject, and indivisibility attributed to the subject which is neither extended nor solid. Who of us, in fact, does not believe himself an indivisible being, one and identical, the same yesterday, to-day, and to-morrow? Well, the word body, the word matter, signifies nothing else than the subject of external phenomena, the most eminent of which are form, impenetrability, solidity, extension, divisibility. The word mind, the word soul, signifies nothing else than the subject of the phenomena of consciousness, thought, will, sensation, phenomena simple, unextended, not solid, etc. Behold the whole idea of spirit, and the whole idea of matter! See, therefore, all that must be done in order to bring back matter to spirit, and spirit to matter: it is necessary to pretend that sensation, volition, thought, are reducible in the last analysis to solidity, extension, figure, divisibility, etc., or that solidity, extension, figure, etc., are reducible to thought, volition, sensation." 1st Series, vol. iii., lecture I, Locke. "Locke pretends that we cannot be certain by the contemplation of our own ideas, that matter cannot think; on the contrary, it is in the contemplation itself of our ideas that we clearly perceive that matter and thought are incompatible. What is thinking? Is it not uniting a certain number of ideas under a certain unity? The simplest judgment supposes several terms united in a subject, one and identical, which is me. This identical me is implied in every real act of knowledge. It has been demonstrated to satiety that comparison exacts an indivisible centre that comprises the different terms of the comparison. Do you take memory? There is no memory possible without the continuation of the same subject that refers to self the different modifications by which it has been successively affected. Finally, consciousness, that indispensable condition of intelligence,—is it not the sentiment of a single being? This is the reason why each man cannot think without saying me, without affirming that he is himself the identical and one subject of his thoughts. I am me and always me, as you are always yourself in the most different acts of your life. You are not more yourself to-day than you were yesterday, and you are not less yourself to-day than you were yesterday. This identity and this indivisible unity of the me inseparable from the least thought, is what is called its spirituality, in opposition to the evident and necessary characters of matter. By what, in fact, do you know matter? It is especially by form, by extension, by something solid that stops you, that resists you in different points of space. But is not a solid essentially divisible? Take the most subtile fluids,—can you help conceiving them as more or less susceptible of division? All thought has its different elements like matter, but in addition it has its unity in the thinking subject, and the subject being taken away, which is one, the total phenomenon no longer exists. Far from that, the unknown subject to which we attach material phenomena is divisible, and divisible ad infinitum; it cannot cease to be divisible without ceasing to exist. Such are the ideas that we have, on the one side, of mind, on the other, of matter. Thought supposes a subject essentially one; matter is infinitely divisible. What is the need of going farther? If any conclusion is legitimate, it is that which distinguishes thought from matter. God can indeed make them exist together, and their co-existence is a certain fact, but he cannot confound them. God can unite thought and matter, he cannot make matter thought, nor what is extended simple."
