For form is surrounded by a certain aura: although it is our most strict definition of space, it also suggests to us the existence of other forms. It prolongs and diffuses itself throughout our dreams and fancies: we regard it, as we regard it, as it were, as a kind of fissure through which crowds of images aspiring to birth may be introduced into some indefinite realm - a realm which is neither that of physical extent nor that of pure thought." - Henri Focillon, The Life of Forms in Art
