Each science is brought into the positive stage when it is co-ordinated according to positive laws—"systematized," Comte would say. He has a perfect mania for systematization; system is with him almost an equivalent for truth. Of course, the real value of every system turns entirely on its co-ordinating method, or principle of formation; and Comte's, we see, was one of positive laws. The nature of these laws is, therefore, the essence and turning-point of the whole matter. I cannot impress upon you too strongly the paramount importance of keeping this truth steadily in view.
But if any one inquires exactly what these laws are, he asks, I fear, a puzzling question. Puzzling, for this reason that, say what one will—employ any words, however carefully selected—one may become liable to the charge of raising a false impression. Positivist savans themselves do not use any uniform phraseology, and many phrases they do use are necessarily derived from philosophies most disedifying to Positive ears.
Examples showing what sort of law is really meant are therefore always welcome; and few could be more instructive than this way of making mind Positive. Comte did not falter in his purpose. Later on he explained the necessity (for his system, you understand) of bringing our intellectual and moral phenomena under the same law with other phenomena of animal life; and reduced them, not to brain action pure and simple, but to cerebral functions, controlled by the viscera and vegetative movements of our bodily existence.
Let us look at the meaning of all this. Soul used to be conceived of as different in kind from body. The brain, the nervous system, the body, were its organs, allies, machines. Sometimes they, especially the instruments through which the soul more immediately works, exercised reaction on their sovereign employer; they impeded or suspended her functions, and troubled her serenity. But though they might cloud the manifestation, they could not destroy the essence of a living soul. What they did was temporal and transitory; but they shall pass away and be dissolved, while soul will endure for ever.
The word mind has been much used to signify soul, as acting in and through body. There is, however, some vagueness in its employment. Yet we constantly speak of the laws of mind, because soul is in this life the partner of body; and therefore known to us as mind, and as mind is studied through its laws. One psychological task has always been to separate the pure activity of soul from the mixed workings of mind, by examination and cross-examination of our internal consciousness.
You will now easily understand how vast the change Comte intended by his physiological organon for the study of our moral and intellectual functions. You will see what is meant by elevating mental science to the Positive stage, and systematizing it under laws which people may variously describe as phenomenal, mechanical, or material; adjectives all roughly used to express the same general idea. What we took for a spiritual essence is only a developed animal nature, the difference between men and beasts of the field is not one of kind, but of degree. ManKIND is a misnomer. Humanity is (as Comte thought) a higher degree of animality. We have no right to suppose a personal immortality. Man may be said to live after death in the memory of his fellow-men, but the truly Positive philosopher believes in no other deathless existence. What we really can see and investigate is a vast moving mechanism, our universe. Beyond this all knowledge is a blank. We know of nothing which set this mechanism in motion; it may have moved from all eternity; it may go on moving everlastingly; or it may wear itself out. Philosophy can teach us no more than distinctions and degrees in the phenomenal law which pervades and rules a universe without a God.
Yet Comte said that he was no Atheist. He even denounced Atheism, and declared it as bad as theology. He did not wish to deny, only to ignore God. Neither did he desire to appear ungrateful; (pardon words which sound in your ears profanity;) God was a really useful hypothesis once; in the days when men had recently issued from their primæval forests. Thanking the Deity for His provisional services, Comte courteously dismissed Him from His throne.
All this will have seemed to you a most monstrous tissue of negations. But Comte held it to be a code of Positive faith; a faith firmly grounded on the self-sufficingness of human nature, read according to his version of course—void of belief in a personality which survives the grave, without knowledge of, trust in, or prayer to God. The blessings of this advanced faith he desired to extend far and wide. At the present moment his desire is realizing itself; for the like attitude of thought has become a favourite position among the savans of our Western world. When it penetrates the more active classes, we shall discern it easily by its fruits! what those fruits will be, is a question for statesmen and for us all.
The chief hindrance opposing its spread amongst unsophisticated minds has been a point much dwelt upon of old by Plato, and by Cicero after him. It is the protest which that irrepressible entity called soul perseveres in alleging. We are all apt to shrink from the picture of bodily dissolution:
"To lie in cold obstruction, and to rot;
This sensible warm motion to become
A kneaded clod!"
