Love in animals, has not for its only object animals of the same species, but extends itself farther, and comprehends almost every sensible and think… - David Hume

[R]evolutions of government cannot be effected by the mere force of argument and reasoning;

And any practice, recommended to him, which either serves to no purpose in life, or offers the strongest violence to his natural inclinations; that practice he will the more readily embrace, on account of those very circumstances, which should make him absolutely reject it. It seems the more purely religious, because it proceeds from no mixture of any other motive or consideration. And if, for its sake, he sacrifices much of his ease and quiet, his claim of merit appears still to rise upon him, in proportion to the zeal and devotion which he discovers. In restoring a loan, or paying a debt, his divinity is nowise beholden to him; because these acts of justice are what he was bound to perform, and what many would have performed, were there no god in the universe. But if he fast a day, or give himself a sound whipping; this has a direct reference, in his opinion, to the service of God. No other motive could engage him to such austerities. By these distinguished marks of devotion, he has now acquired the divine favour; and may expect, in recompence, protection and safety in this world, and eternal happiness in the next.

Men's views of things are the result of their understanding alone. Their conduct is regulated by their understanding, their temper, and their passions.
