Edmund BurkeObstinacy, sir, is certainly a great vice; and in the changeful state of political affairs it is frequently the cause of great mischief. It happens, however, very unfortunately, that almost the whole line of the great and masculine virtues--constancy, gravity, magnanimity, fortitude, fidelity, and firmness--are closely allied to this disagreeable quality, of which you have so just an abhorrence; and in their excess all these virtues very easily fall into it.
