 This is an account of trope individuation that seems to respect the way tropes are normally picked out, yet which does not—circularly—individuate tropes with reference to the objects they make up and which does not rule out the existence of ‘free-floaters’. In spite of this, the majority of the trope theorists (Schaffer 2001 being an important exception) have opted instead for primitivism (cf.  Schaffer 2001: 248 and Ehring 2011: 76; cf. also Campbell 1990: 69; Keinänen &amp; Hakkarainen 2014). Primitivism is best understood as the denial of the idea that there is any true and informative way of filling out the biconditional “For any exactly resembling tropes a and b, a ≠ b iff …”. That a and b are distinct—if they are—is hence primitive. It has no further (ontological) analysis or (metaphysical) explanation.
