—in which wild agitation there is no folly, nor idle fancy they do not light upon:—
"Velut aegri somnia, vanae
Finguntur species."
["As a sick man's dreams, creating vain phantasms."—
Hor., De Arte Poetica, 7.]
The soul that has no established aim loses itself, for, as it is said—
"Quisquis ubique habitat, Maxime, nusquam habitat."
["He who lives everywhere, lives nowhere."—Martial, vii. 73.]
When I lately retired to my own house, with a resolution, as much as possibly I could, to avoid all manner of concern in affairs, and to spend in privacy and repose the little remainder of time I have to live, I fancied I could not more oblige my mind than to suffer it at full leisure to entertain and divert itself, which I now hoped it might henceforth do, as being by time become more settled and mature; but I find—
"Variam semper dant otia mentem,"
["Leisure ever creates varied thought."—Lucan, iv. 704]
