Popper thus identifies falsifiability to demarcate not "meaningful" from "meaningless" but simply "scientific" from "unscientific" a label not in itself unfavorable.
Popper acknowledged this but maintained that a critical approach respecting methodological rules that avoided such "immunizing stratagems" is conducive to the progress of science.
Popper proposed replacing verifiability with falsifiability as the landmark of scientific theories, and replacing induction with falsification as the empirical method.
