-For problem soving feature of the empirical science, see Popper's life-works and publications. The same hold for his demarcation of 'true' science and 'pseudo' science (apparently: metaphysics).
-However, metaphysics regards the 1st person science (see Heinz Pagels ,Perfect Symmetry, pp. 361 ff.). Why should the 1st person science be discarded for the sake of solving the 'factual' problems?
Why are assumptions and presuppositions, (shortly: metaphysics) prejudgedly not worth inquiring?
-Thanks for your answer(s)! Marc.
