Possible Worlds/Popper: There are logically infinitely many possible worlds. The system that we call "empirical science" is supposed to represent ("experienced reality") only one "real world." Three demands:
1. it must be synthetical (represent a non-contradictory world).
2. it must not be metaphysical (represent a possible "Experience World").
3. must be somehow excellent over other systems._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
