Science stands where it does, not simply by virtue of the genius, the industry, the example of its most distinguished representatives, but because by those representatives the whole sphere of its activity is being directed and controlled. The care of the Universities, the care of learned societies, the care of devoted enthusiasts, its interests and honour are watchfully and jealously guarded. The qualifications of its teachers are guaranteed by tests prescribed by the highest authorities on the subjects professed. To standards fixed and maintained by those authorities is referred every serious contribution to its literature. Even a popular lecturer, or a popular writer, who undertook to be its exponent would be exploded at once if he displayed ignorance and incompetence. Such, indeed, is the solidarity of its energies that it is rather in the degrees and phases of their manifestation than in their essence and characteristics that they vary. There is not a scientific institution in England the regulations and aims of which do not bear the impress of such masters as Huxley and Tyndall and their disciples; not a work issuing from the scientific Press which is not a proof of the influence which such men have exercised and are exercising, and of the high standard exacted and attained wherever Science is taught and interpreted. It is far otherwise with Literature. Those who represent it, in a sense analogous to that in which the men who have been referred to represent Science, have neither voice nor influence in its organization, as a subject of instruction, at the centres of education. They neither give it the ply, nor in any way affect its standards and its character in practice and production. As examples few follow them, as counsellors no one heeds them. They constitute what is little more than an esoteric body, moving in a sphere of its own.
