If we had a keen vision and feeling it would be like hearing the grass grow and the squirrel's heart beat, and we should die of the roar which lies on the other side of silence. As it is, the quickest of us walk about well wadded with stupidity.
Our instructed vagrancy, which has hardly time to linger by the hedgerows, but runs away early to the tropics, and is at home with palms and banyans - which is nourished on books of travel, and stretches the theatre of its imagination to the Zambesi.
George Eliot (1819 - 1880)

For what we call illusions are often, in truth, a wider vision of past and present realities - a willing movement of a man's soul with the larger sweep of the world's forces - a movement towards a more assured end than the chances of a single life.
