Refer him to the notion of ETHICS, aka moral philosophy,based on reason,not science..,
Quote:Ethics (also known as moral philosophy) is a branch of philosophy that addresses questions about morality — that is, concepts such as good and evil, right and wrong, justice, virtue, etc.
Major branches of ethics include:
Meta-ethics, about the theoretical meaning and reference of moral propositions and how their truth-values (if any) may be determined;
Normative ethics, about the practical means of determining a moral course of action;
Applied ethics, about how moral outcomes can be achieved in specific situations;
Moral psychology, about how moral capacity or moral agency develops and what its nature is; and
Descriptive ethics, about what moral values people actually abide by.
