L'absence diminue les médiocres passions, et augmente les grandes, comme le vent éteint les bougies et allume le feu.

“When the sword is once drawn, the passions of men observe no bounds of moderation.”
No. 16 http://www.constitution.org/fed/federa16.htm : The Insufficiency of the Present Confederation to Preserve the Union
The Federalist Papers (1787–1788)
Context: When the sword is once drawn, the passions of men observe no bounds of moderation. The suggestions of wounded pride, the instigations of irritated resentment, would be apt to carry the States against which the arms of the Union were exerted, to any extremes necessary to avenge the affront or to avoid the disgrace of submission. The first war of this kind would probably terminate in a dissolution of the Union.

J'ai un but, une tâche, disons le mot, une passion. Le métier d'écrire en est une violente et presque indestructible.

“Of all violent passions, the least unbecoming to a woman is love.”

Quoted in A Dictionary of Quotations, in Most Frequent Use by D.E. Macdonnel (1809) translated from French: Le bonheur de l'homme en cette vi ne consiste pas á être sans passions: il consiste à en être le maître.
