"Can the word ‘best’ mean anything at all, except to some particular person in some particular mood? Perhaps not — so if we allow the word to stand as an absolute, you, or you, or perhaps you, may be appalled at omissions or inclusions or, never having read me before, may even be impelled to cry out, ‘Good heavens, are those his best?’"
