“Why is the imagery there?” someone asked me this week.
To ask this question is perhaps indicative of thinking about the poem or lyrical prose passage too much and (to paraphrase Charlie Chaplin) feeling it too little. One might as well say, “what is the purpose of poetry?” (Sadly, one joyless Mr Spock type Science teacher once did, before going on to declare that it “serves no function”! It seemed that for him love, humour and enjoyment in general were illogical and thus “irrelevant, captain”).
