I was reading an article in the Stanford Encyclopedia of Philosophy about Hans Reichenbach 1, and I have a specific question about it that I would like to ask. There, it is said that:
Reichenbach was quite explicit that logic is not empirical. “The rules of logic cannot be affected by physical experience.” (p. 102). His logic with Indeterminate as a value of propositions is the same as logic with “not empirically meaningful” as a value. In Reichenbach's view that is the logic, as it were, with or without quantum mechanics.
However in an article by Wesley Salmon called "Carnap, Hempel and Reichenbach on Scientific Realism", he appears to indicate that Reichenbach did propose that logic was empirical through logical empiricism since the article begins this way:
"Carnap, Hempel, and Reichenbach, the three leading figures in the movement of logical empiricism, were born in Germany"
Does this mean that Reichenbach eventually changed his opinion and considered that logic was empirical?
