From Burke's Corner:
Tom Butler went on to talk about "the messy ambiguities" of making ethical decisions in society. Ideologies of left and right despise such messy ambiguities - they prefer ideological abstractions. Burke made this point against the Jacobins he confronted:
"The nature of man is intricate; the objects of society are of the greatest possible complexity; and therefore no simple disposition or direction of power can be suitable either to man's nature, or to the quality of his affairs ... 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."
