The paper explores a Fregean inspired conception on what concerns the nature of logical laws. A basic idea is that logic must ‘take care of itself’, i.e., nothing topic-specific could play the role of ground for a logical law. In this Fregean mood, we’ll see as isolating logical laws requires to separate being true from taken to be true. Such a path will lead us through a discussion on the role of representation in its relation to the true and the false. Logic’s proper justification (proof) concerns returning to more basic truths, but justifying such truths is something beyond its scope. According to Frege, logical laws are grounded solely on being true, which brings us back to the question about these laws’ relation to topic-specific matters, as well as their revision.
