[catalogued under 8. Modes of Existence / B. Properties / 11. Properties as Sets]

Full Idea

Rather than directly constructing properties as sets of objects and proving neat facts about properties by proxy, we can assert biconditionals, such as that an object has a property if and only if it is in a certain set.

Gist of Idea

Construct properties as sets of objects, or say an object must be in the set to have the property

A Reaction

Linsky is describing Russell's method of logical construction. I'm not clear what is gained by this move, but at least it is a variant of the usual irritating expression of properties as sets of objects.
