thought only, feels already, in his dark London school, a thread of the Greek mind on this matter vibrating strongly in him. At fifteen he is discoursing on Plotinus, as in later years he reflects from Schelling that flitting intellectual tradition. He supposes a subtle, sympathetic co-ordination between the ideas of the human reason and the laws of the natural world. Science, the real knowledge of that natural world, is to be attained, not by observation, experiment, analysis, patient generalisation, but by the evolution or recovery of those ideas directly from within, by a sort of Platonic "recollection"; every group of observed facts remaining an enigma until the appropriate idea is struck upon them from the mind of a Newton, or a Cuvier, the genius in whom sympathy with the universal reason becomes entire. In the next place, he conceives that this reason or intelligence in nature becomes reflective, or self-conscious. He fancies he can trace, through all the simpler forms of life, fragments of an eloquent prophecy about the [78] human mind. The whole of nature he regards as a development of higher forms out of the lower, through shade after shade of systematic change. The dim stir of chemical atoms towards the axis of crystal form, the trance-like life of plants, the animal troubled by strange irritabilities, are stages which anticipate consciousness. All through the ever-increasing movement of life that was shaping itself; every successive phase of life, in its unsatisfied susceptibilities, seeming to be drawn out of its own limits by the more pronounced current of life on its confines, the "shadow of approaching humanity" gradually deepening, the latent intelligence winning a way to the surface. And at this point the law of development does not lose itself in caprice: rather it becomes more constraining and incisive. From the lowest to the very highest acts of the conscious intelligence, there is another series of refining shades. Gradually the mind concentrates itself, frees itself from the limitations of the particular, the individual, attains a strange power of modifying and centralising what it receives from without, according to the pattern of an inward ideal. At last, in imaginative genius, ideas become effective: the intelligence of nature, all its discursive elements now connected and justified, is clearly reflected; the interpretation of its latent purposes being embodied in the great central products of creative art. The secret of creative [79] genius would be an exquisitely purged sympathy with nature, with the reasonable soul antecedent there. Those associative conceptions of the imagination, those eternally fixed types of action and passion, would come, not so much from the conscious invention of the artist, as from his self-surrender to the suggestions of an abstract reason or ideality in things: they would be evolved by the stir of nature itself,
