This is in contrast to platonistic theorists which intersubjective toward interobjective realism and platonistic stronger logical positivists teleology and ontology both, not the neither-nor of groundless existentialism/nihilism and what sees Chrysippus boot Plotinus and his pawn Russell, that stronger platonism and stronger logical positivism wins with both teleology and ontology and the strong idealist and analytic and techno-analytic philosophy, and of science. It's said Popper adding falsifiability, yet then he's a weaker sort of logical positivist, which is merely again an inductive, linear empirical pragmatist. With no ontological commitment at all except there not being one, .... Not professionals, ..., where for example Einstein provides at least two notions of a scientific observer: "rote inductive model physicist", and "idealist thorough model philosopher".
