An Application of Intuitionistic Fuzzy Sets to Ethics

Abstract: A number of ethical philosophers pointed out the need of introducing a multiple-valued logic in ethics, but nobody has attempted to propose a concrete framework materializing this idea. In the present paper intuitionistic fuzzy sets are used as tools for mathematicizing the ethical rules and interpreting the ethical dilemmas. Our examples are focused on the trolley problem and the dilemma of the searching assassin and the outcomes are compared to the outcomes of our earlier attempt to use soft and neutrosophic sets as tools for the same reason.
