A reason to be rational

This essay argues that in spite of the powerful arguments by Kolodny and Broome there is a reason to be rational. The suggested reason to be rational is that if an agent complies with rational requirements the people around him, as well as he himself, will be able to explain and predict his attitudes. Rationality allows us to make sense of an agent’s attitudes in terms of his other attitudes. This form of explainability is valuable, because it provides us with greater comprehension as regards an agent’s attitudes. Thus, I argue that there is an instrumental reason to be rational.
