[catalogued under 18. Thought / E. Abstraction / 7. Abstracta by Equivalence]

Full Idea

A principle of abstraction is 'conceptual' when the items upon which it abstracts are concepts (e.g. a one-one correspondence associated with a number), and 'objectual' if they are objects (parallel lines associated with a direction).

Gist of Idea

We can abstract from concepts (e.g. to number) and from objects (e.g. to direction)
