Philosophical accounts of humour standardly account for humour in terms of what happens within a person. On these internalist accounts, humour is to be understood in terms of cognition, perception, and sensation. These accounts, while valuable, are poorly situated to engage the social functions of humour. They have difficulty engaging why we value humour, why we use it define ourselves and our friendships, and why it may be essential to our self-esteem. In opposition to these internal accounts, I offer a social account of humour. This account approaches humour as a social practice. It foregrounds laughter and participation, and thereby gives an account of humour that helps to understand why we value humour, why we use it as we do, and why we use it to define our relationship to the world.

The paper articulates a novel strategy against external world skepticism. It shows that a modal assumption of the skeptical argument cannot be justified.

Actions receive teleological descriptions and reason explanations. In some circumstances, these descriptions and explanations might appeal not just to the agent’s own purposes and reasons, but also to the purposes and reasons of others in her social surroundings. Some actions have a social teleology. I illustrate this phenomenon and I propose a concept of vicarious action to account for it. An agent acts vicariously when she acts in response to the demand of another agent who knew that her demand was likely to succeed. I argue that vicariousness grounds the social teleology of the resulting actions.

I argue that, given certain prominent views of personal identity and prudence, the nonidentity problem, or a very similar problem, can arise postconception. I clarify and defend this claim by considering the implications of these views for prenatal injury.

Section I gives an overview of the contents of “Words and Contents”, and lays out the plan for this Critical Notice. Section II expounds Vallée’s Perry-inspired Pluri-Propositional semantic framework, and Section III is an in-depth case study, focused on complex demonstratives. In Sections IV-V we develop some criticisms, and in Section VI we suggest a solution to these difficulties, which builds on Vallée’s innovative work.
