Single Idea 22315

[filed under theme 7. Existence / D. Theories of Reality / 8. Facts / d. Negative facts ]

Full Idea

On Russell's pre-war conception it is obvious that a complex cannot be negative. If a complex were true, what would make it false would be its non-existence, not the existence of some other complex.

Gist of Idea

There can't be a negative of a complex, which is negated by its non-existence

Source

A Reaction

It might be false because it doesn't exist, but also 'made' false by a rival complex (such as Desdemona loving Othello).
