"Nature is not fixed but fluid. Spirit alters, moulds, makes it. The immobility or bruteness of nature is the absence of​ spirit; to pure spirit, it is fluid, it is volatile, it is obedient. Every spirit builds itself a house; and beyond its house, a world; and beyond its world, a heaven. Know then, that the world exists for you. For you is the phenomenon perfect."

R. W. Emerson, Nature
