7. Existence / D. Theories of Reality / 8. Facts / d. Negative facts
22316 A positive and negative fact have the same constituents; their difference is primitive [Russell]
8. Modes of Existence / A. Relations / 1. Nature of Relations
21576 With asymmetrical relations (before/after) the reduction to properties is impossible [Russell]
