 It is arguable that Russell’s definition of definite descriptions was the most prominent early example of the philosophical distinction between surface grammatical form and logical form, and thus marks the beginnings of linguistic analysis as a method in philosophy. Linguistic analysis begins by looking past superficial linguistic form to see an underlying philosophical analysis. Frank Ramsey described the theory of descriptions as a “paradigm of philosophy” (Ramsey 1929, 1). While in itself surely not a model for all philosophy, it was at least a paradigm for the other examples of logical constructions that Russell listed when looking back on the development of his philosophy in 1924. The theory of descriptions has been criticized by some linguists and philosophers who see descriptions and other noun phrases as full-fledged linguistic constituents of sentences, and who see the sharp distinction between grammatical and logical form as a mistake.
