That observation about legal education could be said of ethics as well. Ethics, unlike mathematics, typing, and property law, does not seem to have a discrete beginning. In mathematics you must learn to count, to add and subtract, before you multiply and divide. Algebra comes before calculus. But in ethics we seem never to start at the beginning.
Serious difficulties begin to set in when that kind of stabilizing context is absent.
As we continue down the scale, things go from bad to worse as the incommensurabilities of other times and other cultures are added to the difficulties occasioned by physical distance. In other cases, the interpretive efforts of readers and listeners are tied, even if in some attenuated way, to specifiable empirical conditions, but in the case of fiction and drama those conditions are a construct of the author and in turn must be reconstructed, without the aid of extramental entities, by readers and listeners. Following Fish, we might argue ethics can't be taught simply because we do not know each other. Some feminists argue they do not. The humanist perspective suggests they do.
