Philosophers are often beholden to a picture of language as a largely static, well-defined structure which is handed over from generation to generation by an arduous process of learning: language, on this view, is something that we are given, and that we can make use of, but which we play no significant role in creating ourselves. This picture is often maintained in conjunction with the idea that several distinctively human cognitive capacities could only develop via the language acquisition process, as thus understood. This paper argues that the phenomenon of homesign, i.e., spontaneous gesture systems devised by deaf children for the purpose of communicating with their non-signing peers, can shed valuable empirical light on these convictions. Contrary to grounding assumptions of Wittgensteinian, Gricean, and Peircean approaches to language, homesign shows how core properties of language—including semantic properties—can be built from the ground up in idiosyncratic ways to serve the communicative needs of individuals.

This article argues against Anna Stilz's recent attempt to solve the problem of citizens' collective responsibility in democratic states. I show that her solution could only apply to state actions that are (in legal terminology) unjustified but excusable. Stilz's marquee case – the 2003 invasion of Iraq – does not, I will argue, fit this bill; nor, in all likelihood, does any other case in recorded history. Thus, this article concludes, we may allow that Stilz's argument offers a theoretically cogent case for citizens' task-responsibility in democratic states (given the right conditions); it just so happens that few if any cases satisfy these conditions.
