to be kept in some relation to the general facts of this epoch. Cosmology is the effort to frame a scheme of the general character of the present stage of the universe. The cosmological scheme should present the genus, for which the special schemes of the sciences are the species. The task of Cosmology is twofold. It restrains the aberrations of the mere undisciplined imagination. A special scheme should either fit in with the general cosmology, or should by its conformity to fact present reasons why the cosmology should be modified. In the case of such a misfit, the more probable result is some modification of the cosmology and some modification of the scheme in question. Thus the cosmology and the schemes of the sciences are mutually critics of each other. The limited morphology of a special science is confessedly incapable of expressing in its own categoreal notions all forms which are illustrated in the world. But it is the business of a cosmology to be adequate. For this reason a cosmology must consider those factors which have not been adequately embraced in some science. It has also to include all the sciences.
The din recesses of experience present immense difficulties for analysis. The mere interrogation of immediate consciousness at one immediate moment tells us very little. Analytic power vanishes under such direct scrutiny. We have recourse to memory, to the testimony of others including their memories, to language in the form of the analysis of words and phrases — that is to say, to etymology and syn-
