The Doors of Perception

The Doors took their name from the title of Aldous Huxley's The Doors of Perception (a reference to the 'unlocking' of 'doors' of perception through psychedelic drug use), Huxley's own title was a quote from William Blake's The Marriage of Heaven and Hell, in which Blake wrote that "If the doors of perception were cleansed everything would appear to man as it is, infinite."

"There are things known and things unknown... and in between are the doors..."
