“God pity the man or the nation wise in proverbs, I told myself, for there is much misery and much error gone into the collecting of such a store.”

Attributed

Attributed in Zebras & Picket Fences (2008) by Jakob Weiss; if this is a statement by Feather, it clearly derives from the earlier remarks of Isaac D'Israeli: "The wisdom of the wise, and the experience of ages, may be preserved by quotation." Since at least 1986 a paraphrased form misattributed to his son Benjamin Disraeli has also often been quoted: "The wisdom of the wise and the experience of the ages are perpetuated by quotations."

Eunuchus

Les hommes sont fort à plaindre d'avoir à être gouvernés par un roi, qui n'est qu'homme semblable à eux; car il faudroit des dieux pour redresser les hommes. Mais les rois ne sont pas moins à plaindre, n'étant qu'hommes, c'est-à-dire foibles et imparfaits, d'avoir à gouverner cette multitude innombrable d'hommes corrompus et trompeurs.
