After a time some more searching critics were amazed at sentences which spoke volumes, and showed that Emerson, though he had never written a systematic treatise on philosophy, stood on a firm foundation of the accumulated philosophic thought of centuries. Let us take such a sentence as “_Generalisation is always a new influx of divinity into the mind—hence the thrill that attends_.” To the ordinary reader such a sentence can convey very little; it might seem, in fact, a mere exaggeration. But to those who know the long history of thought connected with the question of the origin of conceptual thought as the result of ceaseless generalisation, Emerson’s words convey the outcome of profound thought. They show that he had recognised in general ideas, which are to us merely the result of a never-ceasing synthesis, the original thoughts or logoi underlying the immense variety of created things; that he had traced them back to their only possible source, the Divine Mind, and that he saw how the human mind, by rising from particulars to the general, was in reality approaching the source of those divine thoughts, and thus becoming conscious, as it were, of the influx of divinity. Other philosophers have expressed similar thoughts by saying that induction is the light that leads us up, deduction the light that leads us down. Mill thought that generalisation is a mere process of mother-wit, of the shrewd and untaught intelligence; and that, from one narrow point of view, it is so, has been fully proved since by an analysis of language. Every word is a generalisation, and contains in itself a general idea, the so-called root. These first generalisations are, no doubt, at first the work of mother-wit and untaught intelligence only, and hence the necessity of constantly correcting them, whether by experience or by philosophy. But these words are nevertheless the foundation of all later thought, and if they have not reached as yet the fulness of the Divine Logoi, they represent at least the advancing steps by which alone the human mind could reach, and will reach at last, the ideas of the Divine Mind.
