Serious work in history of philosophy requires doing something very difficult: conducting a hypothetical dialogue with dead philosophers. Is it worth devoting to it the time and energy required to do it well? Yes. Quite apart from the intrinsic interest of understanding the past, making progress toward solving philosophical problems requires a good grasp of the range of possible solutions to those problems and of the arguments which motivate alternative positions, a grasp we can only have if we understand well (...) philosophy's past. Philosophers who concentrate too much on the present are apt to assume too simple a view of alternative theories and of important philosophical arguments. Ryle and Austin offer instructive examples of how it is possible to go wrong by ignoring or misrepresenting historical figures. (shrink)
