Are there general precepts governing when philosophers should not conduct inquiry on a given topic? When, if ever, should a philosopher just be silent? In this paper we look at a number of practical, epistemic, and moral arguments for philosophical silence. Some are quite general, and suggest that it is best never to engage in philosophical inquiry, while others are more domain – or context – specific. We argue that these arguments fail to establish their conclusions. We do, however, try to identify and defend several substantive constraints on philosophical dialogue and inquiry. In practice, though, respecting these constraints needn't lead to much philosophical silence.

Is it absurd to believe that, in the absence of bodily continuity, personal identity could be retained? Bernard Williams argued for an affirmative answer to this question partly on the basis of a well-known thought experiment. Some other philosophers, including D. Z. Phillips, have accepted, or appear to have accepted, Williams’ conclusion. Yet the argument has the consequence of dismissing as absurd the sorts of reincarnation beliefs which, within their proper contexts, have a meaningful role in the lives of many millions of people. Drawing upon philosophical work by David Cockburn, and also on anthropological studies concerning reincarnation beliefs, this paper questions the extent to which ostensibly meaningful beliefs can be deemed unintelligible in the absence of careful attention to their cultural contexts.

In recent years there has been wide-ranging discussion of epistemic virtues. Given the value and importance of acquiring knowledge this discussion has tended to focus upon those traits that are relevant to the acquisition of knowledge. This acquisitionist focus ignores or downplays the importance of epistemic restraint: refraining from seeking knowledge. In contrast, in many periods of history, curiosity was viewed as a vice. By drawing upon critiques of curiositas in Middle Platonism and Early Christian philosophy, we gain useful insights into the value and importance of epistemic restraint. The historical discussion paves the way for a clarification of epistemic restraint, one that distinguishes the morally relevant features of epistemic process, content, purpose, and context. Epistemic restraint is identified as an important virtue where our epistemic pursuits pose risks and burdens, where such pursuits have opportunity costs, where they are pursued for vicious purposes. But it is in the social realm where epistemic restraint has most purchase: epistemic restraint is important both because privacy is important and because being trusted are important. Finally, some suggestions are offered as to why epistemic restraint has not received the contemporary attention that it deserves.

Hume's account of the passions is largely neglected because the author's purposes tend to be missed. The passions were accepted by early modern philosophers, of whatever persuasion, as the mental effects of bodily processes. The dualist and the materialist differed over whether reason is a higher power able to judge and control them: thus Descartes affirms, whereas Hobbes denies, this possibility. Hume's account lines up firmly behind Hobbes. Although he shies away from Hobbes's dogmatic physiological claims, he affirms all the key elements of the psychology Hobbes based on them: the nature of the will, the compatibility of freedom and necessity, the subservience of reason to passion, and the motivating power of pleasure and pain. Hume's account is thus best regarded as implicitly materialist. It is not, however, merely disinterested analysis: it aims at criticism of orthodox religious values. The passions are not threats to morality, but virtuous or vicious according to their pleasurable or painful nature. Thus the status of pride and humility is reversed. Hume's account of the passions underpins a rejection of orthodox religious morals, and endorses the values of antiquity – of pagan virtue.

The great bulk of what we are pleased to deem knowledge comes to us via the words of others. But such knowledge is limited to (mere) information or plain fact. Theoretical, Ethical and Aesthetic discourse are three regions in which, even when we accept the words of others, we transmit content with what I dub prefaces, not flatly, not in our own voice. Explanation of this is suggested: in these regions assertions claim truth without claiming knowledge. So fact-theory and fact-value differ from plain fact for similar reasons, reasons which alleviate the urge to downgrade ethical discourse to the expressive or prescriptive.

This article is a contribution to discussions about the prospects for a viable conceptualism, i.e., a viable view that represents our modes of awareness as conceptual all the way down. The article challenges the assumption, made by friends as well as foes of conceptualism, that a conceptualist stance necessarily commits us to denying animals minds. Its main argument starts from the conceptualist doctrine defended in the writings of John McDowell. Although critics are wrong to represent McDowell as implying that animals are mindless brutes, it is difficult to see what is wrong with this critical unless we depart from McDowell's technical terminology and introduce a notion of a concept flexible enough to apply to the lives of some non-rational animals. The article closes with a discussion of observations that speak for attributing concepts, flexibly understood, to dogs.

The debates about human free will are traditionally the concern of metaphysics but neuroscientists have recently entered the field arguing that acts of the will are determined by brain events themselves causal products of other events. We examine that claim through the example of free or voluntary switch of perception in relation to the Necker cube. When I am asked to see the cube in one way, I decide whether I will follow the command (or do as I am asked) using skills that reason and language give to me and change my brain states accordingly. The voluntary shift of perspective in seeing the Necker cube this way or that exemplifies the top-down control exercised by a human being on the basis of the role of language and meaning in their activity. It also indicates the lived story that is at the centre of each human consciousness. In the third part of this essay, three arguments are used to undermine metaphysical objections to the very idea of top-down self control.
