Once more,--another explanation given by Littré is, that Positivism lies strictly within the "relative." Many here are aware how, since Kant's time, England, France, and Germany have been flooded with metaphysic, good, bad, and indifferent, on the relative and the conditioned. Pity that Littré should have plunged into these whirlpools! Ravaisson refers to Herbert Spencer and Sophie St. Germain for the point that this conception, the relative, must always imply the existence of an absolute, known or unknown.[169] I cannot follow him now, but any one interested in doing so will find the subject commenced at page 66 of his "Philosophie en France," (one of the Imperial Reports), and continued through sections 9 and 10. It is a very important discussion. Ravaisson stands out amongst Frenchmen as a consummate master of his science; and he inclines to infer that Comte tended, and that Positivism generally now tends, towards a final return to metaphysic. However this may be, I fear I have tired you, and am glad to quit this dry part of my lecture, and get away to more common-sense ground. By way of introducing our most interesting topic, let me draw one common-sense conclusion from the difficult tract just shot over. During our passage, a thought may have flashed upon you which I remember hearing in a Bampton Lecture, somewhat to this effect--"Positivism is the most negative system of all." It appears hard to avoid this idea; for Positivism denies in express terms that human beings have any knowledge outside those generalized laws of experience which make up the Positive sciences. It denies (in a word) the most essential part of what was formerly held to be a knowledge of mind, both human and Divine. Positive thinkers rebut the charge of negativism this way. We confine ourselves, they say, to what we know; we do not venture, like Pantheists and Atheists, into the unknowable. We do not deny God, we only ignore Him. We do not ask about the first cause of the world, or whether it has a constructural final end. Such questions as these are "disedifying." "The Positive philosophy," says Littré, "does not busy itself with the beginning of the universe, if the universe had a beginning--nor yet with what happens to living things, plants, animals, men, after their death, or at the consummation of the ages, if the ages have a consummation."[15] Littré's sentence, which I have rendered _verbatim_, reminds one of the prayer told to Bishop Atterbury, as offered by soldier on the eve of battle: "O God, if there be a God, save my soul, if I have a soul!" I am sorry to repeat ill-sounding words again; but is not this really the exact religious attitude of an honest Positivist, who feels sometimes touched by visions of possible life after death, "Of all the nurse and all the priest have taught;" that is, if we conceive his attitude according to the _least_ negative interpretation put upon the system?
