Frege on Logical Laws and Judgement: On the Normative Constitutivity Reading

ABSTRACT The Strong Normative Constitutivity reading of logical laws in Frege argues that although he regards logical laws as purely descriptive, he in fact accepts that they are normatively constitutive of the act of judgement. There are passages in which Frege seems to commit himself to such an idea. However, we can understand what Frege argues in those passages based only on his conception of logical laws as the most general descriptive laws and his objectivism about truth. If my suggested interpretation is correct, there is a reason to think that logical laws are merely descriptive for Frege. Further, my interpretation shows that the central issue between Frege and psychological logicians is the nature of truth.
