Ludwig Wittgenstein has often been called a quietist. His work has inspired a rich and varied array of theories in moral philosophy. Some prominent meta-ethicists have also been called quietists, or ‘relaxed’ as opposed to ‘robust’ realists, sometimes with explicit reference to Wittgenstein in attempts to clarify their views. In this chapter, I compare and contrast these groups of theories and draw out their importance for contemporary meta-ethical debate. They represent countercultures to contemporary meta-ethics. That is, they reject in different (...) ways one or more of the common assumptions that, whilst not universally shared, shape how to understand and engage in contemporary meta-ethical debate. Despite striking similarities, I argue that the ‘quietist’ label has obscured the views it is used to describe, the crucial differences between them, and the challenge that they offer to the predominant culture of meta-ethical enquiry. That challenge is this: there are plausible different ways of understanding and doing meta-ethics to those of the meta-ethical orthodoxy. We ignore such heterodoxy at our own peril. (shrink)

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.
