"The same strength of character which helps a man resist love, helps to make it more violent and lasting too. People of unsettled minds are always driven about with passions, but never absolutely filled with any."
"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."
