Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

This provocative book attempts to resolve traditional problems of identity over time. It seeks to answer such questions as 'How is it that an object can survive change?' and 'How much change can an object undergo without being destroyed'? To answer these questions Professor Heller presents a theory about the nature of physical objects and about the relationship between our language and the physical world. According to his theory, the only actually existing physical entities are what the author calls 'hunks', (...) four-dimensional objects extending across time and space. This is a major contribution to ontological debate and will be essential reading for all philosophers concerned with metaphysics. (shrink)

Debunking arguments are arguments that aim to undermine some range of beliefs by showing that those beliefs are not appropriately connected to their subject matter. Arguments of this sort rear their heads in a wide variety of domains, threatening beliefs about morality, mathematics, logic, color, and the existence of God. Perceptual beliefs about ordinary objects, however, are widely thought to be invulnerable to such arguments. I will show that this is a mistake. I articulate a debunking argument that purports to (...) undermine our most basic perceptual beliefs. I then challenge a number of responses to the argument, including the “permissivist” response that there are a plenitude of objects before us, virtually guaranteeing the accuracy of our object beliefs.

Sharon Street (2006) has argued that, given certain plausible evolutionary considerations, normative realism leads to normative skepticism. Street calls this ‘the Darwinian dilemma’. This paper considers the two most popular responses to the Darwinian dilemma and argues that both are problematic. According to the naturalist response, the evolutionary account of our normative dispositions reveals that there was selection for normative dispositions that were reliable with respect to normative truth. According to the minimalist response, the evolutionary account reveals that there was (...) selection of normative dispositions that were reliable with respect to normative truth. This paper argues that the minimalist response is in principle unacceptable, and that the naturalist response faces a very serious difficulty. (shrink)

In the Garden of Eden, we had unmediated contact with the world. We were directly acquainted with objects in the world and with their properties. Objects were simply presented to us without causal mediation, and properties were revealed to us in their true intrinsic glory.

Were I not afraid of appearing too philosophical, I should remind my reader of that famous doctrine, supposed to be fully proved in modern times, “That tastes and colours, and all other sensible qualities, lie not in the bodies, but merely in the senses.” The case is the same with beauty and deformity, virtue and vice. This doctrine, however, takes off no more from the reality of the latter qualities, than from that of the former; nor need it give any (...) umbrage either to critics or moralists. Though colours were allowed to lie only in the eye, would dyers or painters ever be less regarded or esteemed? There is a sufficient uniformity in the senses and feelings of mankind, to make all these qualities the objects of art and reasoning, and to have the greatest influence on life and manners. And as it is certain, that the discovery above-mentioned in natural philosophy, makes no alteration on action and conduct; why should a like discovery in moral philosophy make any alteration?

The present paper focuses on essentialism about natural kinds as a case study in order to illustrate this more general point. Saul Kripke and Hilary Putnam famously argued that natural kinds have essences, which are discovered by science, and which determine the extensions of our natural kind terms and concepts. This line of thought has been enormously influential in philosophy, and is often taken to have been established beyond doubt. The argument for the conclusion, however, makes critical use of intuitions, (...) and I note that the intuitions are of the sort had by preschool children, and that they are traceable to a deep-seated cognitive outlook, which is often called “psychological essentialism.” Further, if we did not have such a cognitive outlook or implicit belief set—a belief set which is in fact in place by at least age 4—then we would not have the relevant philosophical intuitions. In light of this, I consider the question of whether natural kinds actually have scientifically discovered or discoverable essences, and whether these putative essences could determine the extensions of our terms and concepts as Kripke, Putnam, and many others have supposed. In fact, a number of philosophers of biology and chemistry have argued that biological and chemical kinds do not have such essences, yet these arguments—particularly in the case of chemistry—have not been assimilated by philosophers more generally. The reason for this poor assimilation is, I suggest, that the Kripke/Putnam view is just so intuitive. But this fact, I argue, is due to a deep-seated cognitive bias, rather than to any special insight into the nature of reality. (shrink)

This chapter presents an opinionated account of how to understand the contributions of experience, especially with respect to the role of cognitive science, in developing and assessing metaphysical theories of reality. I develop a methodological basis for the idea that, independently of work in experimental philosophy focused on explications of concepts, contemporary metaphysical theories with a role for experiential evidence can be fruitfully connected to empirical work in psychology, especially cognitive science. My argument is not that cognitive science should replace (...) the metaphysician’s use of a priori theorizing and ordinary experience as a guide to metaphysical reality. Rather, we should enrich our perspective on a priori theorizing and ordinary experience as a guide to metaphysical reality by drawing on any relevant work in cognitive science. (shrink)

Some things we can know just by thinking about them: for example, that identity is transitive, that Gettier’s Smith does not know that the man who will get the job has ten coins in his pockets, that the ratio between two and six holds also between one and three, that it is wrong to wantonly torture innocent sentient beings, and various other things that simply strikeus, intuitively, as true when we consider them. The question is how : how can we (...) know things just by thinking about them? (shrink)
