In one of his arguments for taking compassion to be the basis of morality, Schopenhauer offers a thought experiment involving two characters: Titus and Caius. The 'Titus Argument,' as I call it, has been misunderstood by many of Schopenhauer's readers, but is, I argue, worthy of attention by contemporary ethicists and metaethicists. In this chapter, I clarify the argument's structure, methodology, and its key philosophical move, drawing comparisons with Newton's experimental methodology in optics and Raimond Gaita's moral parodies.

It is often assumed that moral questions ask for answers in the way other questions do. In this article, moral and non-moral versions of the question ‘Should I do x or y?’ are compared. While non-moral questions of that form typically ask for answers of the form ‘You should do x/y’, so-called ‘narrow answers’, moral questions often do not ask for such narrow answers. Rather, they ask for answers recognizing their delicacy, the need for a deeper understanding of the meaning (...) of the alternatives and the fact that moral decisions are, as Gaita formulates it, ‘non-accidentally and inescapably’ the agent’s to make. In short, moral questions often ask for a kind of answer that is highly different from the kind of answer non-moral questions ask for. In presupposing the ideal answer to a moral question to be a narrow answer, moral philosophers have tended to overlook this. (shrink)

The fact that real-world decisions made by artificial intelligences (AI) are often ethically loaded has led a number of authorities to advocate the development of “moral machines”. I argue that the project of building “ethics” “into” machines presupposes a flawed understanding of the nature of ethics. Drawing on the work of the Australian philosopher, Raimond Gaita, I argue that ethical dilemmas are problems for particular people and not (just) problems for everyone who faces a similar situation. Moreover, the (...) force of an ethical claim depends in part on the life history of the person who is making it. For both these reasons, machines could at best be engineered to provide a shallow simulacrum of ethics, which would have limited utility in confronting the ethical and policy dilemmas associated with AI.

Jeff McMahan has long shown himself to be a vigorous and incisive critic of speciesism, and in his essay “Our Fellow Creatures” he has been particularly critical of speciesist arguments that draw inspiration from Wittgenstein. In this essay I consider his arguments against speciesism generally and the species-norm account of deprivation in particular. I argue that McMahan's ethical framework is more nuanced and more open to the incorporation of speciesist intuitions regarding deprivation than he himself suggests. Specifically, I argue that, (...) given his willingness to include a comparative dimension in his “Intrinsic Potential Account” he ought to recognize species as a legitimate comparison class. I also argue that a sensible speciesism can be pluralist and flexible enough to accommodate many of McMahan's arguments in defense of “moral individualist” intuitions. In this way, I hope to make the case for at least a partial reconciliation between McMahan and the “Wittgensteinian speciesists”, e.g. Cora Diamond, Stephen Mulhall, and Raimond Gaita. (shrink)

This paper defends “moral individualism” against various arguments that have been intended to show that membership in the human species or participation in our distinctively human form of life is a sufficient basis for a moral status higher than that of any animal. Among the arguments criticized are the “nature-of-the-kind argument,” which claims that it is the nature of all human beings to have certain higher psychological capacities, even if, contingently, some human beings lack them, and various versions of the (...) idea that there is a special form of life that all human beings share but of which no animal can be a full participant. The paper concludes that none of these arguments succeeds in demonstrating that there are moral reasons to permit animals to be treated less well than members of our own species whose psychological capacities and potential are no higher than those of the animals.

What is a moral argument? A straightforward answer is that a moral argument is an argument dealing with moral issues, such as the permissibility of killing in certain circumstances. I call this the thin sense of ‘moral argument’. Arguments that we find in normative and applied ethics are almost invariably moral in this sense. However, they often fail to be moral in other respects. In this article, I discuss four ways in which morality can be absent from moral arguments in (...) the thin sense. If these arguments suffer from an absence of morality in at least one of these ways, they are not moral arguments in what I will call the thick sense of ‘moral argument’. Because only moral arguments in the thick sense could possibly qualify as proper responses to moral problems, the absence of morality in thin arguments means that these arguments will fail to give us a reason to do whatever they claim that we ought to do, even if we see no independent reason to question the truth of the premises or the logical validity of the argument.

A polemical account of Australian philosophy up to 2003, emphasising its unique aspects (such as commitment to realism) and the connections between philosophers' views and their lives. Topics include early idealism, the dominance of John Anderson in Sydney, the Orr case, Catholic scholasticism, Melbourne Wittgensteinianism, philosophy of science, the Sydney disturbances of the 1970s, Francofeminism, environmental philosophy, the philosophy of law and Mabo, ethics and Peter Singer. Realist theories especially praised are David Armstrong's on universals, David Stove's on logical probability (...) and the ethical realism of Rai Gaita and Catholic philosophers. In addition to strict philosophy, the book treats non-religious moral traditions to train virtue, such as Freemasonry, civics education and the Greek and Roman classics. (shrink)

Alsted was a foremost encyclopedist of the early seventeenth century. He provided both a complete presentation of all the subjects of philosophy (of which encyclopedia consisted) and a method to learn them. This method was an original synthesis of the dialectic of Petrus Ramus, the combinatorial art of memory of Raimond Lull and Giordano Bruno, and the method of presentation of philosophical disciplines of Bartholomäus Keckermann. Alsted’s encyclopedism was intended as a remedy to the postlapsarian condition of man and (...) was functional to the pedagogical reform pursued at the Academy of Herborn; this was, in turn, an essential part of the Calvinist state reform of the county of Nassau-Dillenburg. In theology, the importance of Alsted consists of having introduced millenarianism in the Reformed Europe, though his early, optimistic views on the imminent end of the world would change to pessimistic as a consequence of the Thirty Years’ War.
