QUOTE : When I saw any external object, my consciousness that I was seeing it would remain between me and it, enclosing it in a slender, incorporeal outline which prevented me from ever coming directly in contact with the material form; for it would volatilise itself in some way before I could touch it, just as an incandescent body which is moved towards something wet never actually touches moisture, since it is always preceded, itself, by a zone of evaporation.
