 Strawson argued that the truth-table semantics of the logical connectives (e.g., formula_1, formula_2 and formula_3) do not capture the meanings of their natural language counterparts ("and", "or" and "if-then").While the "ordinary language" movement basically died out in the 1970s, its influence was crucial to the development of the fields of speech-act theory and the study of pragmatics.Many of its ideas have been absorbed by theorists such as Kent Bach, Robert Brandom, Paul Horwich and Stephen Neale.
