"It is a mighty error to suppose that none but violent and strong passions, such as love and ambition, are able to vanquish the rest. Even idleness, as feeble and languishing as it is, sometimes reigns over them; it usurps the throne and sits paramount over all the designs and actions of our lives, and imperceptibly wastes and destroys all our passions and all our virtues."
"Men are often so foolish as to boast and value themselves upon their passions, even those that are most vicious. But envy is a passion so full of cowardice and shame that no one every ever had the confidence to own it."
"Nature seems to have treasured up the depth of our mind talents and abilities that we are not aware of; it is the privilege of the passions alone to bring them to light, and to direct us sometimes to surer and more excellent aims than conscious effort could."
"The passions are the only orators that are always successful in persuading. They are a kind of art in nature, that proceeds upon infallible rules; and the plainest man, with the help of passion, shall prevail more than the most eloquent man without it."
"The passions do very often give birth to others of a nature most contrary to their own. Thus avarice sometimes brings forth prodigality, and prodigality avarice; a man's resolution is very often the effect of levity, and his boldness that of cowardice and fear."
"Those great and glorious actions that dazzle our eyes with their luster are represented by statesmen as the result of great wisdom and excellent design; whereas, in truth, they are commonly the effects of the humors and passions."
