A beautiful thinking curiousity
The poet I've quoted below, Christian Bok, is a sound poet, who has written a book called Eunoia (which features that poem) in which each chapter uses only one vowel.
The title eunoia, which literally means beautiful thinking or well mind in the Greek, is a (rarely used) medical term which refers to the state of normal mental health, and is also the shortest word in the English language which contains all five vowels.
In rhetoric, eunoia is the goodwill a speaker cultivates between himself and his audience, a condition of receptivity. In book eight of Nicomachean Ethics, Aristotle uses the term to refer to the kind and benevolent feelings of goodwill a spouse has which form the basis for the ethical foundation of human life. Cicero translates eunoia with the Latin word benevolentia. (I've gathered all of this from Wikipedia.)
Isn't that interesting?
