According to Existence Monism, there is only one concrete object in existence—the world. This view is to be contrasted with Existence Pluralism, which posits multiple concrete objects. In a recent Analysis paper, Sider (Analysis 2007; 67:1–7) presents arguments against Existence Monism claiming that there are evident features of statespace, which the monist is at a loss to explain. Given that the pluralist can give plausible and satisfying explanations of these features, we have good reason to favor pluralism over monism, or (...) so Sider supposes. This article constitutes a response to Sider’s claims. I will show how, by appealing to the world’s properties as opposed to the world’s parts, the monist is able to explain these features of statespace perfectly well. (shrink)
