Abstract
In the last chapter of Ethics and the Limits of Philosophy , Bernard Williams brings to a conclusion a sustained attack on the pretensions of moral theory by arguing against the allegedly objective reality of moral obligation. It had been a theme of the book that, while there can be answers to the questions of how one should live and order one's social relationships—answers which, in a given culture, go to make up its ethics —there is no place for a morality or a moral theory which would claim to give externally binding answers to such questions. We will be explaining the notion of an ‘externally binding answer’ later in this paper, but for the moment we can take such an answer to be one that applies to people irrespective of their beliefs or desires. Williams considers Kant to have been the main proponent of the notion of morality in this sense, with the latter's stress on obligation as central to the institution of morality
