Why Do We See a Classical World?
  From a general abstract system theoretical perspective, a quantum-like system description in the spirit of a generalized Quantum Theory may appear to be simpler and more natural than a classically inspired description. We investigate the reasons why we nevertheless conceive ourselves embedded into a classically structured world. Categorial, physical and pragmatic reasons are proposed as explanations.
