Maintain a constant watch at all times against a dogmatical spirit: fix not your assent to any proposition in a firm and unalterable manner, till you have some firm and unalterable ground for it, and till you have arrived at some clear and sure evidence.
To be angry about trifles is mean and childish; to rage and be furious is brutish; and to maintain perpetual wrath is akin to the practice and temper of devils; but to prevent and suppress rising resentment is wise and glorious, is manly and divine.
