 Russell’s multiple relation theory, that he held from 1910 to around 1919, argued that the constituents of propositions, say ‘Desdemona loves Cassio’, are unified in a way that does not make it the case that they constitute a fact by themselves. Those constituents occur only in the context of beliefs, say, ‘Othello judges that Desdemona loves Cassio’. The real fact consists of a relation of Belief holding between the constituents Othello, Desdemona, and Cassio; \(B(o,d,L,c)\). Because one might also have believed propositions of other structures, such as \(B(o,F,a)\) there need to be many such relations \(B\), of different “arities”, or number of arguments, hence the name “multiple relation” theory. Like the construction of numbers, this construction abstracts from what a number of occurrences of a belief have in common, namely, a relation between a believer and various objects in a certain order. The account also makes the proposition an incomplete symbol because there is no constituent in the analysis of ‘\(x\) believes that \(p\)’ that corresponds to ‘\(p\)’. As a result Russell concludes that:
