The pretended rights of these theorists are all extremes: and in proportion as they are metaphysically true, they are morally and politically false. The rights of men are in a sort of middle, incapable of definition, but not impossible to be discerned. The rights of men in government are their advantages; and these are often in balances between differences of good; in compromises between good and evil, and sometimes between evil and evil. Political reason is a computing principle: adding, subtracting, multiplying, and dividing, morally and not metaphysically or mathematically, true moral denominations.
