In the penultimate remark of the Tractatus Logico-Philosophicus Wittgenstein declares that anyone who understands him judges the book to be nonsense. The immediate reaction to this paradoxical statement is to reject the insights of the book that this assessment is based on; that is, to reject the book’s theories of logic and language. Commentators have tried to save the book’s fundamental philosophical ideas by blocking this immediate response. In this thesis I characterise and explore different attempts to do so. I (...) discuss attempts of Russell, Carnap, Max Black, Malcolm, Hacker’s Ineffability interpretation and Conant’s Therapeutic interpretation. I argue that the Therapeutic reading is the most promising attempt in its main ideas. Nonetheless, current versions of the Therapeutic readings do not seem successful. I borrow ideas from Grice’s pragmatic theory of conversation and Davidson’s account of metaphor to explain how the book is to be read therapeutically. I argue that the book is a long conversation between Wittgenstein and his audience which eventually turns out to be a pointless series of remarks. The book, however, works metaphorically in such a way that it affects its readers and helps them to divest themselves of the inclination to do philosophy. (shrink)

This dissertation examines the implications of seeing moral beliefs and moral behaviour as evolutionary adaptations. In particular, it discusses whether or not an evolutionary explanation of human moral behaviour should lead us to reject the idea of objective moral facts. I agree with Michael Ruse that moral behaviour can be explained in naturalistic terms. However Ruse believes that this should not lead us to reject some forms of moral realism, as morality is a shared adaptation. My arguments against this are (...) twofold. Firstly I believe that if morality is a product of natural forces then there will be variation between individuals’ moral sense; which should give us cause to reject all forms of moral realism. My second argument is that Ruse is internally inconsistent, and he is trying to ‘sneak’ moral facts back into the picture, having previously rejected them. (shrink)

In 1982 Saul A. Kripke proposed a reconstruction of the central insights of Ludwig Wittgenstein's remarks on rule-following. The reconstruction prominently featured a sceptical challenge which soon was recognised as a new and very radical form of scepticism. According to the challenge there is no fact of the matter which constitutes meaning. As there is no such fact, the first-person authority people intuitively seem to have concerning what they mean is also baseless. In response to the sceptic, many solutions have (...) been proposed. This thesis is about one family of solutions, according to which facts about meaning are sui generis and can neither be reduced to other facts about the world nor to non-semantic facts about the human mind. The non-reductionist proposals by Colin McGinn and Crispin Wright will be assessed in detail and arguments against both will be introduced. The arguments stem only partially from Kripke himself, some are based on recent literature, others are completely new. The emerging situation will be used as a basis to propose an alternative non-reductionism about meaning-facts. (shrink)

I defend the claim that some things genuinely matter to human beings. This involves overcoming a series of arguments which suggest that the things that matter to us are arbitrary. These arguments arise out of Nagel’s claim that life is absurd. The thesis also discusses different senses in which life can be said to have meaning. I put religious accounts of the meaning of life to one side. Instead, I focus on outlining how someone can experience their own life as (...) meaningful. My main aim is to show that some things genuinely matter. I argue that some things genuinely matter from the perspective of the individual in virtue of the fact that they can become conscious of their own needs. So, there are facts about human nature that, taken together, show that some things genuinely matter to us. These include our vital needs, our happiness and positive relationships with others. I argue that these things matter to us not simply in virtue of the fact that we happen to think that they matter. Rather, they genuinely matter to us given our nature. (shrink)

The cognitive science of religion is a relatively recent attempt to explain religious beliefs using the methods of cognitive science. There has been interest amongst an ever increasing number of scientists, philosophers and theologians as to the impact this research might have on the justification of the religious beliefs themselves. I will examine the impact the cognitive science of religion has upon Alvin Plantinga’s reformed epistemology, which claims that belief in God can be warranted even if it is not based (...) on evidence. Throughout the course of discussion, I shall consider if the cognitive science of religion poses epistemological and ontological problems for Plantinga’s model of theistic belief. I shall claim that the cognitive science of atheism offers a more plausible challenge to Plantinga’s account than the cognitive science of religion. (shrink)
