We suggest that reason is very much like any other cognitive mechanism—it is itself a form of intuition. Like other intuitions, it is a specialised mechanism. The specificity of reason is to bear... on reasons. Reason delivers intuitions about relationships between reasons and conclusions: some reasons are intuitively better than others. When you want to convince someone, you use reason to construct arguments. When someone wants to convince you of something, you use reason to evaluate their arguments. We are swayed by reasons that are intuitively compelling and indifferent to reasons that are intuitively too weak. Reason, then, does not contrast with intuition as would two quite different systems. Reason, rather, is just a higher order mechanism of intuitive inference.
