238. For we ought to be careful never to do anything rashly or carelessly, or anything at all for which we cannot give a reasonable ground. For though a reason for our action is not given to every one, yet everybody looks into it. Nor, indeed, have we anything whereby we can excuse ourselves. For though there is a sort of natural force in every passion of ours, yet that same passion is subject to reason by the law of nature itself, and is obedient to it. Cic. de Off. I. 29, § 102. Wherefore it is the duty of a careful watchman so to keep a lookout, that passion may not outrun reason nor utterly forsake it, lest by outstripping it confusion be caused, and reason be shut out, and come to nothing by such desertion. Disquiet destroys consistency. Withdrawal shows cowardice and implies indolence. For when the mind is disquieted passion spreads wide and far, and in a fierce outburst endures not the reins of reason and feels not the management of its driver so as to be turned back. Wherefore as a rule not only is the soul perturbed and reason lost, but one’s countenance gets inflamed by anger or by lust. it grows pale with fear, it contains not itself in pleasure, and cannot bear joy.
