A proposition, for Whitehead, is neither true nor false in itself. It is a lure for feeling the world that “might be.” A proposition is what places a concrescing subject (an occasion of experience) in relation to a potential predicative pattern. It is the potential togetherness of subject and predicate that characterizes a proposition and not its actual exemplification. But propositions do not hang in the thin air of abstraction; they always emerge from somewhere and are entertained by an actual subject within a particular milieu. The proposition’s relevance and importance (or its “truth”—in William James’ sense) is contingent upon the world that it finds itself within.
