Research and engineering have a decisive impact on the development of the society, providing not only the material artifacts, but also the ideas and other "tools of thought" used to conceptualize and relate to the world. Scientists and engineers are therefore required to take into consideration the wel-fare, safety and health of the public affected by their professional activities. Research and Engineer-ing Ethics are highly relevant for the field of computing (with Intelligent Systems/AI as its sub-field). Computing Ethics has thus been developed as a particular branch of Applied Ethics. By pro-fessional organizations, ethical judgment is considered an essential component of professionalism. This paper will point out the significance of teaching ethics, especially for the future AI profession-als. It argues that education in Ethics should be incorporated in computing curricula. Experience from the course "Professional Ethics in Science and Engineering" given at Mälardalen University in Sweden is presented as an illustration.
