'Why not,' he says. He runs his eye over the human instrumentalities, and this art which we call _art--par excellence_, which he sees setting up for itself, or ministering to ignorance and error, and feeding the diseased affections with 'the sweet that is their poison,' he seizes on at once, in behalf of his science, and declares that it is her lawful property, 'her slave, born in her house,' and fit for nothing in the world but to minister to her; and what is more, he suits the action to the word--he brings the truant home, and reforms her, and sets her about her proper business. That is what he proposes to have done in his theory of art, and it is what he tells us he has done himself; and he has: there is no mistake about it. That is what he means when he talks about his illustrated tradition of science--his illustrated tradition of the science of HUMAN NATURE and its _differences_, _original_ and _acquired_, and the _diseases_ to which it is liable, and the artificial growths which appertain to it. It is very curious, that no one has seen this tradition--this illustrated tradition, or anything else, indeed, that was at all worthy of this new interpreter of mysteries, who goes about to this day as the inventor of a method which he was not able himself to put to any practical use; an inventor who was obliged to leave his machine for men of a more quick and subtle genius, or to men of a more practical turn of mind to manage, men who had a closer acquaintance with nature.
That which is first to be noted in looking carefully at this draught of a new Art of Tradition which the plan of the Advancement of Learning includes,--that which the careful reader cannot fail to note, is the fact, that throughout all this most complete and radical exhibition of the subject (for brief and casual as that exhibition seems on the surface, the science and art from its root to its outermost branches, is there)--throughout all this exhibition, under all the superficial divisions and subdivisions of the subject, it is still the method of PROGRESSION which is set forth here: under all these divisions, there is still one point made; it is still the Art of a Tradition which is designed to reserve the _secrets_ of science, and the nobler arts of it, for the minds and ages that are able to receive them. This new art of tradition, with its new organs and methods, and its living and beautiful illustration, when once we look through the network of it to the unity within, this new rhetoric of science, is in fact the instrument which the philosopher would substitute, if he could, for those more cruel weapons which the men of his time were ready to take in hand; and it is the instrument with which he would forestall those yet more fearful political convulsions that already seemed to his eye to threaten from afar the social structures of Christendom; it is the beautiful and bloodless instrumentality whereby the mind of the world is to be wrenched insensibly from its old place without 'breaking all.'
