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.
