Simply listing the assumptions is not enough. We should explain what each of these assumptions means, and more important, why each of them is needed for the theory to follow. This turns out to be one of the most fundamental parts in theory education. Relaxing the assumptions often means a new theoretical breakthrough. By raising "what if" questions students learn not only the limitation in the theory's applicability but also the various aspects the theory can improve upon. This is how theory education provides the much-needed adaptability, flexibility, and critical thinking ability.
