Once, in a debate with William Lane Craig, atheist Lawrence Krauss stated that science has informed us that homosexuality is not morally wrong. That issue aside, I wondered how many would agree with his basic premises. Would you say science enables us to discover the truth about moral laws? Or are moral laws something that we created and that evolve and change with us?

If we discover morality through science, it would seem that the moral laws are in place independently of our awareness of them, in which case I have to question who they are directed towards or how they got there. Or how we would even know that... And if they are discovered through science, I'd have to ask how that occurs. What sorts of experiments should be carried out to test morality and how are we to interpret the data?

If, on the other hand, morals are a construct of the complex human mind and are therefore subject to change and evolution, then how are we to choose the proper understanding of morality? If two people differ, on what basis do we judge one man's subjective understanding of morality against another's? Should we trust the overall majority of the human population, or a select group?
