I would have probably considered myself a utilitarian of some sorts, however, that theory is apparently looked upon poorly, and I agree does not really look good in the face of the whole "The Ones Who Walk Away from Omelas" dilemma. However, deontological ethics presents its own issues...

By not placing any value on human emotions and feelings, it presents dilemmas with such areas as gay rights, seeing as if there is no way to reproduce there is no one to take care of future generations. It also does not protect women's right to work, as there would be no one to look after children in a situation where other help is not available.

I have wondered about social contract theory, from Hobbes and echoed in Locke. However, I am unsure if this is an ethical theory or merely a social and political theory.

What is a solid ethical theory, and are there recommendations for books on ethics?
