Single Idea 7959

[filed under theme 8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes ]

Full Idea

The problem is how a group of resembling tropes can be of the same type, that is, that they can resemble one another in the same way. This problem is not settled simply by positing tropes.

Gist of Idea

How do a group of resembling tropes all resemble one another in the same way?

A Reaction

There seems to be a fundamental fact that there is no resemblance unless the respect of resemblance is specified. Two identical objects could still said to be different because of their locations. Is resemblance natural or conventional? Consider atoms.

The 22 ideas with the same theme [arguments against the existence of tropes]:

14327 Trope theorists cannot explain how tropes resemble each other [Russell, by Mumford]
15480 Objects are not bundles of tropes (which are ways things are, not parts of things) [Martin,CB]
8538 Trope theory needs extra commitments, to symmetry and non-transitivity, unless resemblance is exact [Armstrong]
4445 If properties and relations are particulars, there is still the problem of how to classify and group them [Armstrong]
15750 Tropes need a similarity primitive, so they cannot be used to explain similarity [Lewis]
15749 Trope theory (unlike universals) needs a primitive notion of being duplicates [Lewis]
15748 Trope theory needs a primitive notion for what unites some tropes [Lewis]
8527 More than one trope (even identical ones!) can occupy the same location [Daly]
8528 If tropes are linked by the existence of concurrence, a special relation is needed to link them all [Daly]
10742 Tropes can overlap, and shouldn't be splittable into parts [Oliver]
4611 The supporters of 'tropes' treat objects as bundles of tropes, when I think objects 'possess' properties [Heil]
4483 If abstract terms are sets of tropes, 'being a unicorn' and 'being a griffin' turn out identical [Loux]
18352 Tropes have existence independently of any entities [Lowe]
8286 Tropes cannot have clear identity-conditions, so they are not objects [Lowe]
8294 How can tropes depend on objects for their identity, if objects are just bundles of tropes? [Lowe]
8295 Why cannot a trope float off and join another bundle? [Lowe]
8296 Does a ball snug in plaster have one trope, or two which coincide? [Lowe]
12253 If tropes are in space and time, in what sense are they abstract? [Oderberg]
4462 A colour-trope cannot be simple (as required), because it is spread in space, and so it is complex [Moreland]
4463 In 'four colours were used in the decoration', colours appear to be universals, not tropes [Moreland]
7959 How do a group of resembling tropes all resemble one another in the same way? [Macdonald,C]
7960 Trope Nominalism is the only nominalism to introduce new entities, inviting Ockham's Razor [Macdonald,C]
