Abstract The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue ethical view as such. Keywords: consequentialism, deontology, emotion, ethics, evolution, innate, moral judgment, moral philosophy, psychology, utilitarianism, virtue.

I found myself at the top of a mountain in the mist, feeling very pleased with myself, not just for having climbed the mountain, but for having achieved my life’s ambition, to find a way of answering moral questions rationally. But as I was preening myself on this achievement, the mist began to clear, and I saw that I was sur- rounded on the mountaintop by the graves of all those other phi- losophers, great and small, who had had the same ambition, and thought they had achieved it. And I have come to see, reflecting on my dream, that, ever since, the hard-working philosophical worms had been nibbling away at their systems and showing that the achievement was an illusion.

I started graduate school so long ago it has become an embarrassment. Former students of mine finished before I did – something that is, our head of department in- formed me in brazen denial of the thesis’ major presupposition, “un- natural and, hence, wrong”. A friend told me, in yet another misguided attempt at cheering me up, that a possible upside to working for such a long time on the dissertation is that my chapter on the evolutionary origins of moral thinking must be the first ever Pleistocene eyewitness account of what really happened back then. Oh well. Anyway, here it is. I wish to thank the many friends and current and previous col- leagues who have provided support over the years.

Many thanks to organizer Ingmar Persson and all the others who participated in those discussions. I was most fortunate to be able to spend a semester working with Gilbert Harman at lovely Princeton University. I thank Gil and the many new friends I made while there, in particular Mark Budolfson, Angela Mendelovici, Philipp Koralus, and Jack Spencer. My stay at Princeton was made possible by grants from The Swedish Foundation for International Cooperation in Research and Higher Education (STINT) and from the Anders Karitz Foundation. I am very grateful to both of these institutions for their support. For many years, I’ve had a second academic home at Karolinska In- stitute’s ethics group within the Department for Learning, Informatics, Management, and Ethics (LIME). I was given the opportunity to pre- sent an early version of chapter four there, and I wish to thank my many good friends at LIME: Gert Helgesson, Annelie Jonsson, Niklas Juth, Petter Karlsson, Anna Lindblad, Niels Lynøe, Tomas Månsson, and Manne Sjöstrand. A third and more recent academic home has been DIS where I’ve taught a course on medical ethics for American students spending a semester in Stockholm.
