Carlos Alberto Montaner considers himself to be an agnostic but he nevertheless writes an essay whose point is that God is a sine qua non of moral judgment, a theme we have often written about ourselves here at Viewpoint. Montaner argues that human rights are contingent upon a transcendent moral authority and that if there is no such entity the whole notion and discussion of rights, as well as, we might add, right and wrong themselves, are little more than subjective blathering about personal preferences and arbitrary tastes.
Here are two paragraphs from Montaner's column:
The whole philosophical and juridical structure that supports liberal democracy hinges on the existence of a superior being from whom emanate the ''natural rights'' that protect individuals from the actions of the state or from the will of other people. If the premise of God's existence disappears, the theory of the existence of natural rights is automatically eliminated and the door is flung open to all kinds of abuses.
It's just that simple. If there are no natural rights, it may be acceptable to enslave prisoners, discriminate against women and execrate foreigners or homosexuals. All that's required is a decision by a legitimate source of power, such as a majority in numbers, for instance, or a group of notable and petulant wise men.
And, of course, if there is no God then there is no such thing as a natural right. Everyone would have the "right" to do whatever he or she has the power to do. Might would make right. If right is not grounded in something objective and transcendent, it simply doesn't exist other than as a matter of mere personal predilection.
