 Supposing that a haecceity is something real, where does it fit into the range of things that there are? Is it, for example, a form, or something else? According to Scotus, it is something like a form, and sometimes, indeed, he calls it such (while elsewhere denying the same claim: on these insignificant terminological shifts, see Dumont [1995]). The reason is that a haecceity is clearly something like a property of a thing – hence like a form – but is at the same time wholly devoid of any correspondence to any conceptual contents. It is not at all a qualitative feature of a thing – not at all a “quidditative” feature, in the technical vocabulary. As irreducibly particular, it shares no real feature in common with any other thing. This does not mean that haecceities cannot fall under the extension of a concept. Being an individuating feature is not a real property of a haecceity (it cannot be, since any haecceity is wholly simple, and shares no real features with any other thing); but any concept of what a haecceity is certainly includes among its components being an individuating feature. A concept of a haecceity includes representations merely of logical, not real, features of any haecceity.
