Formal logic operates through syntactic derivation rules that are independent of semantic content, a principle supported by studies on formal logic deduction and proof theory.
The claim states that formal logic operates through syntactic derivation rules independent of semantic content. This is a foundational, standard definition in mathematical logic and proof theory. Paper [0] explicitly studies logical deduction isolated from knowledge/semantics, and Paper [5] demonstrates syntactic proof theory and derivation rules (such as cut elimination) in formal logic systems. Thus, the supporting papers establish the claim fully, and no papers refute it.
