THE NATURE OF SUBSTANCE

“When people look out into the universe they think that space is empty and that the stars are in this empty space. In times gone by, peasants believed that there was emptiness all around them as they moved about. Today everyone knows that there is air around us, not emptiness. So, too, we can know that in the universe there is no emptiness anywhere; either matter is there or spirit is there.”

Rudolf Steiner
