Single Idea 15133

[catalogued under 28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique]

Full Idea

That there is just one necessary existent is surely false, for if x is a necessary, {x} is a distinct necessary existent.

Gist of Idea

A thing can't be the only necessary existent, because its singleton set would be as well
