There are two things I find frustrating. One is that although I spent a lot of time in graduate school studying ethical theories, I find that they aren't very helpful in trying to resolve real-life dilemmas...The other frustration is that serious ethical disagreements rarely seem to get resolved, and good arguments – or at least, what seem like good arguments to me – rarely seem to change anyone's mind. A new book by Duane Cady...has given me fresh insight on both of these perplexities.
