Richards analysed scientific treatises, political speeches, popular science and poetry, and concluded that in our use of language, one of the functions becomes predominant and that the subject and intention determines the priority and degree of the use of other functions. The principles of a writer’s language are not simple because the furtherance of her/ his intention will interfere with the other functions. For instance, the writer of a scientific treatise puts sense first, subordinates his feeling, establishes his tone by following academic convention, and clearly states his intention, whereas in a political speech intention is predominant, feeling is its instrument to express causes and policies, tone establishes the relations with the audience and sense is the representation of facts. It is in conversation that intention may completely subjugate the others, and therefore feeling. an tone may express themselves through sense. Richards suggests that the perceptive reader should be prepared to apprehend the interplay of the four meanings, which together comprise the total meaning of the poem.
