Man never ceases to seek knowledge about the objects of his experiences, to understand their meaning for his existence and to react to them according to his understanding. Finally, out of the sum total of the meanings that he has deduced from his contacts with numerous single objects of his environment there grows a unified view of the world into which he finds himself "thrown" (to use an existentialist term again) and this view is of the third order.
Paul WatzlawickThat we do not discover reality but rather invent it is quite shocking for many people. And the shocking part about it - according to the concept of radical constructivism - is that the only thing we can ever know about the real reality (if it even exists) is what it is not. It is only with the collapse of our constructions of reality that we first discover that the world is not the way we imagine.

Paul WatzlawickThe belief that one's own view of reality is the only reality is the most dangerous of all delusions.
