The paper presents and defends a new account of reasoning. Reasoning is essentially subject to a constitutive norm, the norm of following sufficient normative reasons. Instead of rule-following, following normative reasons is essential. After clarifying the view, three arguments in its support will be presented. They concern the scope of (correct) reasoning, the value of (correct) reasoning, and the relation between reasoning and treating a consideration as a reason. Two objections – concerning the knowledge norm of belief and cases of (...) improperly treating a consideration as a reason – will be dealt with. (shrink)
