For example, in this way, we can define morality as what is in our best interest. The rules of society (laws) are based on morality. A country, such as the U.S. bases its laws primarily to that of Christian beliefs and the Ten Commandments. However, this is not to say that everyone obeying these laws are Christian. Many people believe that without a religious framework, the only possible conclusion is that all morality is nothing more than a human construct without any objective existence. In other words, the morality a person or a culture accepts is like picking a favorite flavor of ice cream. No person's preference is "more correct" than another's. In a similar manner, different individuals and different societies have various favorite moral belief systems, and just as with ice cream, no particular set of moral beliefs is "more correct" than any other. Different cultures have vastly different moral systems. In fact, on almost any moral issue, it appears that there is absolutely no agreement or consensus shared by even a majority of the cultures. There appears to be no way to prove the superiority of one moral system over another using logic alone. Even though different cultures hold very different beliefs about a certain issue, this does not necessarily imply that there is no objective reality behind these beliefs.
The claim which I will be arguing for is that this is the same for morality as it is for gravity. All the moral beliefs which came before us and all the moral beliefs today are, in exactly the same way as in the case of gravity, approximations to the objective reality which exists independently of human beings. By "objective morality" I do not simply mean that morality exists in the sense that various societies consider various actions to be immoral. What I mean is that certain actions are neither right nor wrong regardless of what any society thinks about them. In other words, I mean that there is an "objective morality" which exists independently of human beliefs and human civilization.
