Clearly these three aspects overlap, intersect and are mutually dependent. Understanding text in the ways indicated in the first 'cultural' aspect, for example, clearly depends on being able to operate successfully in the second 'functional' area. The different aspects overall are also mutually inclusive, and in describing them I have deliberately tried to draw them with wide, accommodating boundaries. By 'issues and values', for example, I mean not just politics, ethics or matters of 'personal development', but questions of cultural and aesthetic quality and importance. By 'functional or instrumental', I don't have in mind merely the ability to write and speak effectively, spell correctly and know where to put an apostrophe, but also the understanding and appreciation of the function of style, argument and persuasion, and the way in which ideas are managed in intersubjective discourse. In the third aspect, functioning creatively in writing and speech requires some developed awareness of how effective communication has occurred in the past, and of the ways in which creative traditions thrive, develop and are expanded.
