Comment: This paper proposes a certain characterisation of what it is to have knowledge of logical principles which makes it compatible with the way in which we reason ordinarily. It can be seen as an alternative to Harman's view in 'Change in View' according to which ordinary people do not at all 'employ' a deductive logic in reasoning. Thus this paper could be used in a course on the role of logic in reasoning, following the reading of Harman's work. More generally, this reading is suitable for any advanced undergraduate course or postgraduate course on the topic of rationality.

Abstract: This paper argues that the prominent accounts of logical knowledge have the consequence that they conflict with ordinary reasoning. On these accounts knowing a logical principle, for instance, is having a disposition to infer according to it. These accounts in particular conflict with so-called 'reasoned change in view', where someone does not infer according to a logical principle but revise their views instead. The paper also outlines a propositional account of logical knowledge which does not conflict with ordinary reasoning.
