Single Idea 8525

[catalogued under 5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic]

Full Idea

Because there cannot be relations without terms, in a meta-physic that makes first-order tropes the terms of all relations, relational tropes must belong to a second, derivative order.

Gist of Idea

Relations need terms, so they must be second-order entities based on first-order tropes

A Reaction

The admission that there could be a 'derivative order' may lead to trouble for trope theory. Ostrich Nominalists could say that properties themselves are derivative second-order abstractions from indivisible particulars. Russell makes them first-order.
