According to a guiding idea in metaethics, there is a necessary link between the concept of normative reasons and the concept of practical rationality. This notion brings up two issues: The exact nature of this link, and the nature of rationality. With regard to the first issue, the debate is dominated by a certain standard claim. With regard to the second issue, the debate is dominated by what I will refer to as ‘subjectivism’ and ‘objectivism’ about rationality, where the latter is assumed to be a necessary condition for the existence of categorical reasons. In this paper, it is argued that subjectivism is able capture an ordinary, non-technical, sense of ‘rational’ whereas objectivism is not. The basic reason is that objectivism fails to account for the essential connection between rationality, malfunctioning, and rational criticism. This means that we face a puzzle: While objectivism appears to be a necessary condition for the existence of categorical reasons, it fails to capture a central sense of ‘rational’. It is finally argued that this puzzle can be solved by abandoning the standard claim about the link between reasons and rationality.
