Why do people think that nonduality means no duality

"The task of knowing is not to recapitulate in the form of concepts what is given to us in another way, but rather to create an entirely new domain which, when combined with the world presented by sense perception, produces for the first time a complete reality. From this point of view, the highest mode of human activity—the creative activity of the mind—organically adapts itself to the complete process of cosmic events. In this activity, the world processing could not be understood as something total and complete in itself. [...] The human being is not a spectator watching the spectacle of the world, imitating in his spirit what is happening in the universe without becoming involved; he is an active participant in a cosmic creative process, and his knowledge is, in fact, the most evolved part of the organism of the universe."

— Rudolf Steiner, Truth and Science (1892)
