Abstract

In his conception of worlds 1-3 Popper did not make clear how the world 3 can influence on world 2 or 1 . On example of music we can see that any human invention of “new” tone combination cannot affect already given tone combinatorics which is in world 3 . Similarily “new” scientific theory cannot make any change in world 3 where all theories are – according to Popper – settled. Opposite direction of influence seems neither possible: human mind can only feel that it is somehow touched by abstract object during its creative activity; to all appearance abstract objects cannot causaly affect on – presumably material – medium of human thinking
