“A speech or an essay may be eloquent, but if it is, the eloquence is incidental to its aim. Eloquence, as distinct from rhetoric, has no aim: it is a play of words or other expressive means. It is a gift to be enjoyed in appreciation and practice. The main attribute of eloquence is gratuitousness: its place in the world is to be without place or function, its mode is to be intrinsic. Like beauty, it claims only the privilege of being a grace note in the culture that permits it.”
Denis Donoghue, On Eloquence
