My passions, when roused, are intense, and, so long as I am activated by them, nothing equals my impetuosity. I no longer know moderation, respect, fear, propriety; I am cynical, brazen, violent, fearless; no sense of shame deters me, no danger alarms me. Except for the object of my passion, the whole world is as nothing to me; but this only lasts for a moment, and the next I am plunged into utter dejection.
