 Singular propositions (also called ‘‘Russellian propositions’’) are propositions that are about a particular individual in virtue of having that individual as a direct constituent. This characterization assumes a structured view of propositions —   see propositions: structured. Alleged examples of singular propositions are the propositions [Mont Blanc is more than 4,000 meters high], [Socrates was wise], and [She (pointing at Susan) lives in New York]. A singular proposition is to be contrasted with a general proposition, which is not about any particular individual, and a particularized proposition, which is about a particular individual but does not contain that individual as a constituent. Examples of the first are the propositions [Most Americans favor tax cuts] and [Some music is great]; examples of the second are the propositions [The inventor of bifocals was bald] and [The tallest spy is a man]. A singular proposition is directly about an individual whereas a particularized proposition is indirectly about an individual in virtue of that object satisfying a condition that is a constituent of the proposition — in our cases, the conditions ‘x uniquely invented bifocals’ and ‘x is a tallest spy’.
