4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / d. System T

14607	T adds □p→p for reflexivity, and is ideal for modeling lawhood [Schaffer,J]
	Full Idea: System T is a normal modal system augmented with the reflexivity-generating axiom □p→p, and is, I think, the best modal logic for modeling lawhood.
	From: Jonathan Schaffer (Causation and Laws of Nature [2008], n46)
	A reaction: Schaffer shows in the article why transitivity would not be appropriate for lawhood.
