A number of concerns have been raised about the possible future use of pharmaceuticals designed to enhance cognitive, affective, and motivational processes, particularly where the aim is to produce morally better decisions or behavior. In this article, we draw attention to what is arguably a more worrying possibility: that pharmaceuticals currently in widespread therapeutic use are already having unintended effects on these processes, and thus on moral decision making and morally significant behavior. We review current evidence on the moral effects (...) of three widely used drugs or drug types: propranolol, selective serotonin reuptake inhibitors, and drugs that effect oxytocin physiology. This evidence suggests that the alterations to moral decision making and behavior caused by these agents may have important and difficult-to-evaluate consequences, at least at the population level. We argue that the moral effects of these and other widely used pharmaceuticals warrant further empirical research and ethical analysis. (shrink)

Now available for the first time in English, this work is widely recognised as a classic in the field of moral theology.

The Summa Theologiae is Thomas Aquinas' undisputed masterwork, and it includes his thoughts on the elemental forces in human life. Feelings such as love, hatred, pleasure, pain, hope and despair were described by Aquinas as 'passions', representing the different ways in which happiness could be affected. But what causes the passions? What impact do they have on the person who suffers them? Can they be shaped and reshaped in order to better promote human flourishing? The aim of this book is (...) to provide a better understanding of Aquinas' account of the passions. It identifies the Aristotelian influences that lie at the heart of the Summa Theologiae, and it enters into a dialogue with contemporary thinking about the nature of emotion. The study argues that Aquinas' work is still important today, and shows why for Aquinas both the understanding and attainment of happiness requires prolonged reflection on the passions. (shrink)
