 But before turning to priority monism, it is worth mentioning in more detail the argument from ontological vagueness that motivates Horgan and Potrč 2000 and 2008. Their core idea, seen in their 2008 (§7.3), is that the ontologist has three main options. She may posit a world full of commonsense objects (“slob-jects”), but at the price of admitting ontological vagueness. Or she may posit a world of many small precise objects (“snob-jects”), which may or many not stand in composition relations. Or she may posit just one precise object, namely the world itself (“the snob-ject is the blob-ject”).
