 A number of different distinctions have been called the intrinsic/extrinsic distinction. As J. Michael Dunn (1990) notes, some authors have used ‘intrinsic’ and ‘extrinsic’ to mean ‘essential’ and ‘accidental’. Dunn is surely right in saying that this is a misuse of the terms. A more interesting distinction is noted by Brian Ellis (1991; discussed in Humberstone 1996: 206). (See also Figdor 2008 and Figdor 2014 for a discussion of a related notion of intrinsicality.) Ellis suggests we should distinguish between properties that objects have independently of any outside forces acting on them (what we will call the Ellis-intrinsic properties), and those that they have in virtue of those outside forces (the Ellis-extrinsic properties). For many objects (such as, say, a stretched rubber band) their shape will be dependent on the outside forces acting on them, so their shape will be Ellis-extrinsic. If one is committed to the idea that shapes are intrinsic, one should think this means that the distinction between the Ellis-intrinsic and Ellis-extrinsic properties is not the same as the intrinsic/extrinsic distinction. Such a judgement may seem a little hasty, but in any case we will turn now to distinctions that have received more attention in the philosophical literature.
