Abstract

Mental conflict not always amounts to weakness of will. Irresistible motives not always speak of addiction. This book proposes an integrated account of what singles out these phenomena: addiction and weakness of will are both forms of secondary akrasia. By integrating these two phenomena into a classical conception of akrasia as poor resolution of an unnecessary conflict – valuing without intending while intending without valuing – the book makes an original contribution to central issues in moral psychology and philosophy of action, including the relationship between responsibility and intentional agency, and the nature and scope of moral appraisal. In particular, the proposed integrated account is grounded in a general theory of responsibility and a related model of action as actualisation bringing together insights from both volitional and non-volitional conceptions, such as the intuition that it is unfair to hold a person responsible for things that are not up to her and the parity of actions and attitudes as legitimate objects of moral appraisal. Furthermore, the actualisation model supports a distinctive version of the Guise of the Good thesis which links valuing and intending in terms of success in action and explains why akratic actions and their offspring – addiction and weakness of will – are necessarily less than successful yet fully responsible.
