Science is as incapable of grasping the individuality of a man as that of a rabbit, being equally indifferent to both. Not that it is ignorant of the principle of individuality: it conceives it perfectly as a principle, but not as a fact. It knows very well that all the animal species, including the human species, have no real existence outside of an indefinite number of individuals, born and dying to make room for new individuals equally fugitive. It knows that in rising from the animal species to the superior species the principle of individuality becomes more pronounced; the individuals appear freer and more complete. It knows that man, the last and most perfect animal of earth, presents the most complete and most remarkable individuality, because of his power to conceive, concrete, personify, as it were, in his social and private existence, the universal law. It knows, finally, when it is not vitiated by theological or metaphysical, political or judicial _doctrinairisme_, or even by a narrow scientific pride, when it is not deaf to the instincts and spontaneous aspirations of life--it knows (and this is its last word) that respect for man is the supreme law of Humanity, and that the great, the real object of history, its only legitimate object, is the humanization and emancipation, the real liberty, the prosperity and happiness of each individual living in society. For, if we would not fall back into the liberticidal fiction of the public welfare represented by the State, a fiction always founded on the systematic sacrifice of the people, we must clearly recognize that collective liberty and prosperity exist only so far as they represent the sum of individual liberties and prosperities. Science knows all these things, but it does not and cannot go beyond them. Abstraction being its very nature, it can well enough conceive the principle of real and living individuality, but it can have no dealings with real and living individuals; it concerns itself with individuals in general, but not with Peter or James, not with such or such a one, who, so far as it is concerned, do not, cannot, have any existence. Its individuals, I repeat, are only abstractions.
