|Positivism, philosophy: modern positivism represents the demand to trace back statements with a claim to explanation to differences which can be ascertained in the objects of investigation. What is ascertainable is, in this case, relativized to a framework theory and its methods. This is intended to exclude foreign and non-verifiable statements. See also empiricism, internal/external, truth, provability.|

PutnamVsPopper/PutnamVsMach: VsPositivismus: is idealistic, does not correspond to reality.
PutnamVsPositivismus: according to him truth is not trans-theoretical - it is only a trans-theoretical concept, "leads to successful prediction" - Putnam: instead: Realism: must adhere to logic of truth transfers.
From the fact that two theories lead to successful predictions, it does not follow, that their conjunction leads to that - reason: the predicate, which plays the role of truth ("leads to prediction") does not have the characteristics of truth.
Meaning/theory/PutnamVsCarnap/VsPositivism: the theory does not determine the significance - otherwise the concept of gravity would change if a 10th Planet would be discovered - also the positivists demand that the theory is also dependent on all additional assumptions, otherwise the scheme of theory and prediction would collapse.
Truth/Positivism: which degree of confirmation one accepts, is ultimately conventional, a question of purpose - Putnam: that is relativism - it has no answer to the enemy that says, "in my system the P is not rational".
