That trolling is a shameful thing, and that no one of sense would accept to be called ‘troll’, all are agreed; but what trolling is, and how many its species are, and whether there is an excellence of the troll, is unclear. And indeed trolling is said in many ways; for some call ‘troll’ anyone who is abusive on the internet, but this is only the disagreeable person, or in newspaper comments the angry old man. And the one who disagrees loudly on the blog on each occasion is a lover of controversy, or an attention-seeker. And none of these is the troll, or perhaps some are of a mixed type; for there is no art in what they do. (Whether it is possible to troll one's own blog is unclear; for the one who poses divisive questions seems only to seek controversy, and to do so openly; and this is not trolling but rather a kind of clickbait.)

This essay offers an interpretation of Hegel's theory of normativity according to which normative evaluation is primarily a matter of a thing's answerability to its own constitutive norms. I show that natural and spiritual norms correspond to two different species of normative evaluation for Hegel, two categorically distinct ways something can violate its own constitutive norms. I conclude with some general reflections on the relationship between normativity and ontology in Hegel's system.

This essay presents a critical examination and development of an exchange between Adam Smith and David Hume on the nature of sympathy. I identify four objections to Smith's account in a letter from Hume and then argue that Smith's system has the resources to reply to all of them. As such, this essay shows that Smith's system provides a more robust foundation for a sentiment-based system of ethics than has been traditionally recognized.

Evolutionary debunking arguments (EDAs) claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument before offering a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution has selected for one belief: belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about.

This paper introduces a framework for thinking about ontological questions—in particular, the Special Composition Question—and shows how the framework might help support something like an account of restricted composition. The framework takes the form of an account of natural objects, in analogy with David Lewis's account of natural properties. Objects, like properties, come in various metaphysical grades, from the fundamental, fully objective, perfectly natural objects to the nomologically otiose, maximally gerrymandered, perfectly non-natural objects. The perfectly natural objects, I argue, are the mereological simples, and (roughly) a collection composes an object of degree-n naturalness if and only if its members are arranged F-wise, for some property F that appears in the degree-n natural laws. Arbitrary composites turn out to be perfectly non-natural objects and are metaphysical bystanders. Ordinary composite objects fall in between. Some—e.g., atoms—are very (though not perfectly) natural; others—e.g., tables—are highly non-natural.

What is the aim of philosophy? There may be too many philosophical branches, traditions, practices, and programs to admit of a single overarching aim. Here, I focus on a fairly traditional philosophical project that has recently received increasingly sophisticated articulation, especially by Frank Jackson (1998) and David Chalmers (2012). In Section 1, I present the project and suggest that it is usefully thought of as ‘total axiomatics’: the project of attempting to axiomatize the total theory of the world. In Section 2, I raise a problem for the project that I call the ‘problem of multiple axiomatizations’. I consider some initially alluring but ultimately unpromising approaches to this problem in Section 3. In Section 4, I defend a surprising approach to the problem, according to which competing axiomatizations of the total theory of the world are effectively evaluated for their aesthetic virtues.

Kant famously insists that free will is a condition of morality. The difficulty of providing a demonstration of freedom has left him vulnerable to devastating attack: critics charge that Kant's post-Groundwork justification of morality amounts to a dogmatic assertion of morality's authority. My paper rebuts this objection, showing that Kant offers a cogent demonstration of freedom. My central claim is that the demonstration must be understood in practical rather than theoretical terms. A practical demonstration of x works by bringing x into existence, and what the demonstration of freedom brings into existence is a moral will, a will regulated by the moral law and capable of acting in accordance with it. Since to act morally is to act freely, bringing a moral will into existence actualizes our capacity for freedom and demonstrates that we possess it. To confirm the viability of such a demonstration, Kant must establish that agents can regulate their wills by practical principles, and that practical judgments are efficacious of themselves (i.e., that non-Humean motivational internalism is true). Kant, I argue, is successful on both counts.

The questions of how to understand free will and mental causation are clearly connected, for events of seemingly free choosing are mental events that appear to be efficacious vis-à-vis other events. Nonetheless, the free will and mental causation debates have proceeded largely independently of each other. Here we aim to make progress in determining the mutual bearing of these debates. We first argue that the problems of free will and of mental causation can be seen as special cases of a more general problem of mental ‘quausation’, concerning whether and how mental events of a given type can be efficacious qua the types they are—qualitative, intentional, freely deliberative—given reasons to think such events are causally irrelevant. We go on to identify parallels between hard determinism and eliminativist physicalism and between soft determinism and nonreductive physicalism, and we use these parallels to identify a new argument against hard determinism and to reveal and motivate a common strategy underlying apparently diverse soft determinist accounts.

Arguments for substance dualism—the theory that we are at least partly nonmaterial beings—abound. Many such arguments begin with our capacity to engage in conscious thought and end with dualism. Such are familiar. But there is another route to dualism. It begins with our moral value and ends with dualism. In this article, we develop and assess the prospects for this new style of argument. We show that, though one version of the argument does not succeed, there may yet be a deep problem for standard physical accounts of our nature.

It is argued that core areas of philosophy can benefit from reflection on cross-disciplinary research (CDR). We start by giving a brief account of CDR, describing its variability and some of the ways in which philosophers can interact with it. We then provide an argument in principle for the conclusion that CDR is philosophically fecund, arguing that since CDR highlights fundamental differences among disciplinary research worldviews, it can be used to motivate new philosophical problems and supply new insights into old problems. We close by providing an argument by example that uses the epistemology of peer disagreement to establish the potential of CDR for core philosophical areas. With this argument, we aim to demonstrate how the complex research contexts that CDR affords can point the way toward important avenues of epistemological research by highlighting potential limitations of key epistemological components, such as peerage and uniqueness.
