Meta-ethical theory reflects on the grounds of moral behavior. Normative ethics tries to answer the question what actions are right or wrong. Patricia Churchland in Braintrust and Peter Singer in Ethics and Intuitions share their thoughts about meta-ethical theory and normative ethics. Churchland relies on neuroscience and evolutionary theory for explaining moral behavior and does not endorse normative ethics. Singer argues Churchland’s arguments are insufficient for explaining moral behavior and states rationality is essential in exploring morality and normative ethics. I defend Peter Singer’s utilitarian moral theory because it adds to normative ethics and is less conflicting than Churchland’s theory.
