We know only what we do, what we make, what we construct ; and all that we make, all that we construct, are realities. I call them images, not in Plato's sense (namely that they are only reflections of reality), but I hold that these images are the reality itself and that there is no reality beyond this reality except when in our creative process we change the images: then we have created new realities.
