Of the reality of intuitive, as distinct from reflected knowledge, we have constant evidence in our immediate experience. If I examine my own consciousness, at any particular moment, I find it crowded with _things I know_, as, now, this room in which I am writing, the piano that is open before me, the flowers in a little basket, blue fragments of sky and green branches washed by the recent rain swaying in the clear sunlight, the shrill voice of a child from the road, the light steps of a girl moving about the house. I am not conscious of all these intuitions at once: I write, and I distinctly _know_ this white paper only, and the black signs I am tracing, the pen guided by my hand, and the edges of a few books on my table: all the rest has faded away into a blurred, fused intuition, the intuition of an atmosphere, composed of mere shreds and shadows of the colours and sounds of which I was so distinctly conscious but one minute ago. But now I put down my pen again, and I look at the piano; and I let my mind wander away, from what I see to what I remember or imagine: the fair-headed figure playing this morning Franck's Prelude, Choral and Fugue, the rapid and sure movements of the fingers on the white and black keys, a vague image of the solemn and passionate music, memories of distant days, a sudden rush of obscure fantasies, evoked by the actual playing, and still lingering in the recesses of my mind, returning now with a fragment of a melody, with a succession of triumphant chords. And again, I look beyond the window, and the little square of green and blue expands itself into the vast valley beyond, screened from my view by these few trees clustering around the house, and yet mysteriously present to my inner eye: I see a little company of riders cantering along a shaded lane, coming out in an open meadow surrounded by low, thick-wooded hills; the sun sets in a pale purple sky, and I hear the tramping of the slow, heavy hoofs, as the horses find their way back through the woods, through a darkness much more opaque and solid than that of the remote twilight, still visible above the highest branches, animated by the first faint glittering of a star. And the woods are full of a myriad small breathing and stirring noises, of the sense of the deep surging inhuman life of trees and shrubs, of the penetrating scent of the rich damp earth, of decaying wood, of fallen leaves.
