 Our disbelief in their [propositions’] reality may be reinforced by asking ourselves what kind of entity a false proposition could be. Let us take some very simple false proposition, say “A precedes B”, when in fact A comes after B. It seems as though nothing were involved here beyond A and B and “preceding” and the general form of dual complexes. But since A does not precede B, these objects are not put together in the way indicated in the proposition. It seems, therefore, that nothing which is actually composed of these objects is the proposition; and it is not credible that anything further enters the proposition. (Russell 1913: 109–10; for a detailed discussion of this argument see Wetzel 1998)
