In all thy humours, whether grave or mellow,

Thou 'rt such a touchy, testy, pleasant fellow,

Hast so much wit and mirth and spleen about thee,

There is no living with thee, nor without thee.

Joseph Addison (1672-1719): Spectator. No. 68.

There is a luxury in self-dispraise;

And inward self-disparagement affords

To meditative spleen a grateful feast.

William Wordsworth (1770-1850): The Excursion. Book iv.
