If you can’t persuade an atheist of the existence of God,you are not likely to persuade him of the existence of natural law either. Natural law is as invisible as God (even more so,since God reveals himself),and as a concept,it is metaphysical. As Pope Benedict wrote in one of his books,modern philosophers reject natural law because it reeks of metaphysics.
Anthony, you are still not getting it. Natural Law is not invisible. It is observable, discernable and in case you are not aware of it, Cultural Anthropology is examining what we call Natural Law, but what they would describe as a unified theory of what constitutes human nature, those universal attributes which the Catholic says are written on the hearts of men and the Cultural Anthropologists would say are discernable across cultures that are very different. You fall for the trap of necessarily equating God with Natural Law. The atheist simply says “God doesn’t exist” and your debate is finished, right there at that point.
As for the Pope saying Natural Law is rejected because of some metaphysical association, to a point he is right, or should I say was right. The scientific method, the Positivist approach, was adopted by all those examining what constitutes human nature. However, it has now been admitted that all the positivist information in the world does nothing to help arrive at a unified theory of human nature, of what constitutes man’s nature. The metaphysical is being explored once again and the different anthropological approaches, which diverged because of the positivist approach, are once again unifying.
The naturalistic perspective is false to begin with. God exists,and he is at work in the natural world. The naturalistic perspective leads to falsehoods wherever it leads people to attribute to natural causes the ability to do things that they logically cannot have the power to do: produce life,order,thought,and make physical things come into existence from nothingness.
There is a massive assumption in this paragraph of yours here. You are assuming that God is determining what the world is and how it operates at every moment in time. Are you sure about that? What do you mean by saying people do not have the power to produce life? God gave us that power and the free will to decide whether or not we use that power. Are are right when you say we can’t make things come into existence from nothingness? What do you mean by nothingness?
If that’s what he meant,there’s a big difference between the need for men to assent to reason and whether or not they do assent to it.
Have you ever heard of unreasonableness? Have you ever heard of the term illogical? Perhaps it is the case that men have to be taught to reason correctly. If that were not the case, surely much of the world’s problems would already be solved?!
I stated my position clearly in the first post. I wrote,“My position is that natural law exists,that it is created by God and is constituted into man’s conscience,human nature and body,and that it can be discerned through reason. But since it is given by God,it ought to be understood in light of what we know about God and man through Catholic doctrine.”
Yes and it was your first post that got people worked up. If you make that statement to an atheist, he will shrug his shoulders and walk away. Once you tie Natural Law into a theological debate, you lose that argument, because every secular scientific forum will consign you to the bin of archaic discourse and the idea of a natural law founded on reason and rational inquiry is virtually lost. You need to obtain for yorself a book called
Jurisprudence: Men and Ideas of the Law (Brooklyn: Foundation Press, 1953, by a Professor Patterson. He defines Natural Law as
Principles of human conduct that are discoverable by “reason” from the basic inclinations of human nature, and that are absolute, immutable and of universal validity for all times and places. This is the basic conception of scholastic natural law … and most natural law philosophers.
Now that quote is over fifty years old and only recently have the cultural sciences who derided the theological and metaphysical arguments in favour of Natural Law arrived at the conclusion that what this quote is saying holds true. That the positivist approach has failed. You firstly need to convince people of the veracity of Patterson’s definition of Natural Law. Then and only then, can you evince an argument in favour of a theological foundation for the existence of Natural Law. If that were not the case, the whole world would be Catholic already.
