I have a sense of it, but most people adopt a relativist view on morality and in that case, that is what you recieve. To be honest, and I don't know if this has to do with my type, but whenever I think of ethics I hate it. In my day to day life moral issues are few--there is no right or wrong--just because it confuses me greatly. There are no clear rules (such as in the realm of logic).
One person's right is another person's wrong on a given moral issue. Do we then say that they are both right in their own contexts (relativism) or that one of them is possibly right, in which case the other must be wrong, or both are completely wrong (universal moral truths)? To be sure, I have a great discomfort in moral relativism in some cases, because it ends up justifying some terrible things. But there is great difficulty in identifying what is a moral fact.
It does seem to me though, there is the possibility of a few universal principles that human cultures throughout history might share, and from there, everything within these principles is relative. This is only a vague idea that I hold--no doubt if I eventually learn more on what has been discussed about ethics, I might understand better.
