Abstract

Today's ethical theory , both utilitarian and non-ontological theories dominated. However, we found that many of its subsequent development in the evolution of those who encourage virtue ethics, feminist care theory, social contract theory and the theory of rights-based build. But usually lacking in this discussion - the teaching of ethics by the majority of it seems - is the natural law theory. Natural law theory has its very long history, starting from the Stoic school, it had occupied in the outside world, a strong Anglo-American influence . But today it is still a strong defender of its existence , Joseph Bauer , and Yue Hanfen Jonas ). But in any case it does absent in most contemporary research into ethics, even when it was put in time, is often quickly oppose the theory. Why this theory is often ignored or opposed? We can give a lot of reasons. Some will mention the problem with it ought to. That is contrary to natural law where the basic claim that a person who can not be on the moral statements of a person's actual state is. Some of the attacks this theory is the theory because it is a natural, stable together on it called) natural fallacy, moral assets is a "simple "and do not be a natural thing to be defined . Some critics oppose the natural law theory because they believe that all laws are based is only the ordinary and customs, so it does not matter the existence of any universal moral law. Others argue that natural law theory assumption that there exists, but there is no reason to believe the world for such a presence. Again, some people think that today there is a widespread skepticism that regardless of this objective, universal the existence of moral standards - in other words, a standard applied to all human beings, regardless of their cultural origin or its existence in time and space. In any case, even if this standard exists, we may still ask where they come from? Can we know what they are? And we can determine their legitimacy? In this paper, Maritain's natural law philosophy as a theoretical basis for showing this philosophy of good reasons to lies. Natural law and moral philosophy to provide the philosophy of the relationship and differences between the lies. Thus natural law is natural, because it - especially its first principles, "can be as good, evil can be avoided." - The content is naturally knowable. The first principle is not innate, but it still is not wrong with the talent. We can through all of the knowledge and understanding, to explain the different knowledge of natural law, natural law is the knowledge of the process. The world as we know more, we also know more of their own; we found congenital beyond time. But the fact of moral knowledge needs to transcend time, it does not make a relationship of knowledge, and scientific knowledge that is required is some, as it is relevant. It concluded that the object of this essay have been presented in Maritain's study of natural law. Of Maritain, natural law is "a tendency to order, one can find it, and it will have to act in accordance to meet the person and the nature of the purpose of the inevitable." Considerations of such a proposal is not only a description of human behavior, also on the basis of moral action and human rights standards. Maritain accepted the idea that this law is not only associated with the human and natural to be known. He believed that his theory of knowledge and to give arguments for metaphysics, we can have a human experience consistent with natural law theory of historical perception, as is should be a bridge, and explain why the differences in the nature of moral knowledge not against natural law of reason. If we can take this route - Maritain from the plant into the road on St. Thomas Aquinas - Maritain believe we can at least respond to the majority of the criticism of natural law theory. Of course, natural law theory, there are more than epistemology and metaphysics considerations. Obviously, there are many other kinds of law related to the demand . We also need to indicate whether we know something of natural law. How can we compare Maritain's theory of natural law and other laws of nature? In particular, once popular in the eighteenth century rationalist ideas. Nevertheless, it is obvious that a complete discussion of this article, we should not totally against Maritain's theory - it should be included in today's major moral theories
