Abstract

Available from UMI in association with The British Library. Requires signed TDF. ;The libertarian conception of free will is incoherent, irrespective of the prospects for determinism. However, both compatibilist and hard determinist accounts of the implications of the lack of libertarian free will are inadequate. This I attempt to show primarily with respect to the notions of desert and justice. Working from a "Core Conception" of justice, I argue that we are obliged to recognize a "Fundamental Dualism" in the morally proper attitude to desert and justice. This means that the compatibilist claim that moral responsibility and justice are not harmed by the lack of libertarian free will is mistaken; but so is the hard determinist claim that no account of moral responsibility and justice is possible once the lack of libertarian free will is realized. The dualistic position proposed attempts to combine the insights of compatibilism and hard determinism, while avoiding their inadequacies. Other alternative positions on the free will issue are also argued to be inadequate. In the light of these considerations it is argued that motivated illusion is a central requirement of moral and personal life. In arguing for the importance of illusion, I claim that it is a reality today, that it is mostly positive, and that by and large it ought to continue. To some extent illusion is unavoidable, but, even more interestingly, there seem to be avoidable but morally necessary illusions. The importance of illusion presents great difficulties in the moral and political sphere as well as in the cognitive sphere. Appreciation of the relatively neglected role of illusion, which follows from the basic structure of the free will problem in its moral aspects, is an important key to making progress on this problem
