Blake

If the doors of perception were cleansed
Everything would appear to Man as it is, Infinite;
For Man has closed himself up, till he sees
All things thro' the narrow chinks of his cavern


-- William Blake

I must attribute my finding of this, one of my favorite but forgotten quotes, to Victor Vertunni Di Albanella, whom I haven't seen since I was 18 and living on Polstead Road in Oxford, but now, apparently runs a theater company and has recorded a rather beautiful album of Blake's poems turned into songs. And this, of course, is where Huxley got his title from.
