Ira  

"Behold me then safely ensconced in my private boudoir, a fearful instance of the ill consequences attending upon irascibility—alive, with the qualifications of the dead—dead, with the propensities of the living—an anomaly on the face of the earth—being very calm, yet breathless."--"Loss of Breath" (1832) by Edgar Allan Poe

"Imperious, choleric, irascible, extreme in everything, with a dissolute imagination the like of which has never been seen, atheistic to the point of fanaticism, there you have me in a nutshell.... Kill me again or take me as I am, for I shall not change."--letter from Sade to his wife
