Abstract
Is reality the basis of everything or has reality itself an other basis? What makes reality –
not the real things – to be active, to exist? The question of what is real seems to be an easy
question, because in our daily lives we are and must be naive realists. We ourselves, the things
around us, the world, the facts, all that is real.
there must be several concepts of reality if we want to say that not only physical or material
things of everyday life are real, e. g. numbers, π, Dr. Faustus, thoughts, emotions and other
things. On the other hand, given the difference of classical physics and modern physics, we
see that even that form of knowledge, which seems to be most responsible for reality, natural
science, cannot give the desired uniqueness in terms of what itself wants or needs to understand
as real.
Alternatively, when we see that nothing can be and nothing can be real without being in a
world, and when we understand the world as the order of things, which I call worldI , then this
leads us to the speculative answer that it is exactly the “unreal” worldI which is the reason why
the everyday reality, worldI I , is real. The worldI is the basis for the reality of our empirical
worldI I .
The considerations presented here have nothing to do with the idealistic conception of possibility,
founded in the power of the subject, nor with the existential concept of potentiality,
founded in the Entwurf des Daseins.
