There is no simple relationship between clarity and language. Apart from a few well-known exceptions, such as in poetry and politics ('Now let me be absolutely clear about this...'), everyone wants to be clear, and everyone admires clarity of expression in others. But clarity cannot be achieved by forbidding the use of whole areas of language, such as figures of speech or classical vocabulary, for the obvious reason that a thought might be best expressed by using precisely those means. Even science makes copious use of metaphors: witness the 'flavours' of quarks in particle physics, or the 'blind watchmaker' of evolutionary biology.
Clarity depends on our making judicious use of all of a language's resources. Words, grammar, rhythm, discourse, and stylistic level all play their part. It is never possible to identify a single dimension or principle of usage, or a cluster of 'rules', and say that these are obligatory features of clarity of expression. When people try to do this, they invariably end up . . . breaking the very principles they have themselves promulgated. We shall see this happening repeatedly, as criticisms of usage grow. (p. 65}
