INCUMBENT, n. A person of the liveliest interest to the outcumbents. - Ambrose Bierce
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
"Only a novel"... in short, only some work in which the greatest powers of the mind are displayed, in which the most thorough knowledge of human nature, the happiest delineation of its varieties, the liveliest effusions of wit and humour are conveyed to the world in the best chosen language. - Jane Austen
