 To get a better handle on the thesis in question, let us agree to understand “thought” broadly as conceptual  activity.[7]  Judging, believing, inferring, for example, are all instances of thinking in this sense. It may seem puzzling at first how logic is to get a normative grip on thinking: Why merely by engaging in conceptual activity should one automatically be answerable to the strictures of  logic?[8]  After all, at least on the picture of thought we are currently considering, any disconnected stream-of-consciousness of imaginings qualifies as thinking. One answer is that logic is thought to put forth norms that are constitutive for thinking. That is, in order for a mental episode to count as an episode of thinking at all, it must, in a sense to be made precise, be “assessable in light of the laws of logic” (MacFarlane 2002: 37). Underlying this thesis is a distinction between two types of rules or norms: constitutive ones and regulative ones.
