[catalogued under 8. Modes of Existence / B. Properties / 10. Properties as Predicates]

Full Idea

Attributes should not be thought of as identifiable objects. It is better to follow Frege and compare them to mathematical functions. 'Square of' and 'double of' x are distinct functions, even though they are not distinguishable in thought when x is 2.

Gist of Idea

Attributes are functions, not objects; this distinguishes 'square of 2' from 'double of 2'

A Reaction

Attributes are features of the world, of which animals are well aware, and the mathematical model is dubious when dealing with physical properties. The route to arriving at 2 is not the same concept as 2. There are many roads to Rome.
