The Importance of Being Rational systematically defends a novel reasons-based account of rationality. The book's central thesis is that what it is for one to be rational is to correctly respond to the normative reasons one possesses. Errol Lord defends novel views about what it is to possess reasons and what it is to correctly respond to reasons. He shows that these views not only help to support the book's main thesis, they also help to resolve several important problems that are independent of rationality. The account of possession provides novel contributions to debates about what determines what we ought to do, and the account of correctly responding to reasons provides novel contributions to debates about causal theories of reacting for reasons. After defending views about possession and correctly responding, Lord shows that the account of rationality can solve two difficult problems about rationality. The first is the New Evil Demon problem. The book argues that the account has the resources to show that internal duplicates necessarily have the same rational status. The second problem concerns the deontic significance of rationality. Recently it has been doubted whether we ought to be rational. The ultimate conclusion of the book is that the requirements of rationality are the requirements that we ultimately ought to comply with. If this is right, then rationality is of fundamental importance to our deliberative lives.

Reviews
Errol Lord's The Importance of Being Rational is a tour de force treatment of the relationship between reasons, rationality, knowledge, and what Lord calls creditworthiness, the kind of achievement where you don't just do what is right, but do it for the right reasons. * Mark Schroeder, Philosophy and Phenomenological Research *
a beautiful presentation of how one might defend a reasons-first approach to rationality. And it has many insights that will be useful to non-reasons-firsters as well. As such, there's a great deal in the details of Lord's arguments that repays careful consideration. * Karl Schafer, Philosophy and Phenomenological Research *
The Importance of Being Rational marks a new moment in debates about the nature of rationality. It is absolutely compulsory reading for epistemologists, ethicists, and meta-ethicists alike. * Nathan Robert Howard, Ethics *
rich, ambitious, and thought-provoking * Olle Risberg, European Journal of Philosophy *
an essential reading in the literature on reasons. * Julia Staffel, The Philosophical Review *
an admirable philosophical feat that rewards careful study. It is essential reading for anyone interested in the nature, and worth, of rationality. * Carlos Nunez, The Philosophical Quarterly *
an informed, original, rich, sophisticated and exceptionally well-illustrated case for the claim that what we are rationally required to do and what we substantially ought to do is really the same thing. To follow Errol Lord on his route to this conclusion is a frequently rewarding experience and one that is well worth undertaking. * Hallvard Lillehammer, Notre Dame Philosophical Reviews *
