Leitgeb writes: “Thus, according to Quine, while the stimulus meaning of an observation sentence can be identified with its meaning if the sentence is taken holophrastically, i. e. as a single-word expression ..., this is no longer possible if the observation sentence is not taken holophrastically, i. e. if it is taken analysed as being syntactically composed of meaningful parts” ( ibid ., p. 418; emphasis is mine).
