In the following chapters, I offer an evolutionary account of morality and from that extrapolate a version of contractarianism I call consent theory. Game theory helps to highlight the evolution of morality as a resolution of interpersonal conflicts under strategic negotiation. It is this emphasis on strategic negotiation that underwrites the idea of consent. Consent theory differs from other contractarian models by abandoning reliance on rational self-interest in favour of evolutionary adaptation. From this, more emphasis will be placed on consent as natural convergence rather than consent as an idealization. My picture of contractarianism, then, ends up looking more like the relativist model offered by Harman, rather than the rational (or pseudo-rational) model offered by Gauthier, let alone the Kantian brands of Rawls or Scanlon. So at least some of my discussion will dwell on why it is no loss to abandon hope for the universal, categorical morality that rational models promise. In the introduction, I offer the betting analogy that underwrites the remaining picture. There are some bets where the expected utility is positive, though the odds of winning on this particular occasion are exceedingly low. In such cases, we cannot hope to give an argument that taking the bet is rational. The only thing we can say is that those predisposed to take this kind of bet on these kinds of occasions will do better than those with other dispositions, so long as such games occur often enough.

Jan Narveson is one of the most significant contemporary defenders of the libertarian political position. Unlike other libertarians who typically defend their view with reference to natural rights or an appeal to utilitarianism, Narveson's main contribution has been to offer a philosophical defence of libertarianism based on a Hobbesian individualist contractarian ethic. Critiques of Narveson's contractarian libertarianism fall into three categories, those that reject contractarian moral theory, those that reject any link between contractarianism and libertarianism and those that accuse libertarians of conflating liberty with property. In this book Malcolm Murray brings together the most significant of Narveson's critics and presents their work alongside replies by Jan Narveson.

The Athiest's Primer is a concise but wide-ranging introduction to a variety of arguments, concepts, and issues pertaining to belief in God. In lucid and engaging prose, Malcom Murray offers a penetrating yet fair-minded critique of the traditional arguments for the existence of God. He then explores a number of other important issues relevant to religious belief, such as the problem of suffering and the relationship between religion and morality, in each case arguing that atheism is preferable to theism. The book will appeal to both students and professionals in the philosophy of religion, as well as general audiences interested in the topic.

In an era of information overload, our need to learn how to critically evaluate the growing flood of information has never been greater. Critical Reflection showcases the role of reason in a world saturated by media-enhanced persuasion and complex scientific and technological jargon.Drawing from the classic philosophical texts, this engaging textbook on the art of analyzing arguments is also relevant to today's undergraduates in its use of real-life examples and exercises drawn mainly from media and politics. Malcolm Murray and Nebojsa Kujundzic cover the standard subjects in a one-semester course on critical thinking, offering ways to analyze arguments
