Speaking at a lunch in a discussion moderated by TV anchor Riz Khan, Serageldin spelled out his vision of the need to separate the methods of empirical investigation (the basis for science) from the act of belief and of philosophical reasoning. Serageldin argued that each of these domains or magisteria had its own authority structure and answered different classes of questions. If you ask what should I do about x or y, that is not a question to which there is a scientific answer. Serageldin impressed his audience by insisting that there were other magisteria as well, for example the aesthetics of art appreciation, which involve sensory experiences that are neither in the magisterium of science nor in the magisterium of religion.
