Any attempt at teaching Ethics in disciplines other than Philosophy should be well justified. One justification is that through ethics teaching across the curriculum, pre-professionals and professionals get well equipped to apply ethical theories to resolve moral crises in practical life. One example is popular enough, i.e., through ethical teaching we prepare competent professionals in our business schools, who may further apply this knowledge in their field as well as assume the role of ethics consultants to resolve moral crisis in the field of management. I have tried to show why such a justification is completely unfounded. A critique of this justification leads us to know what applying ethics consists in and, in what sense teaching ethics across the curriculum, for instance, in business management curriculum may be useful.
