R.I.P., Bernard Williams.
Chris is cataloging obits.
Williams was a touchstone for me in my undergraduate work in ethics and philosophy, works like Ethics and the Limit of Philosophy and his work on moral luck, came to me as virtue theory alongside Alasdaire MacIntyre, and others. He provided a model for a publicly engaged iconoclastic philosopher, able to find real problems in philosophy and explain their historical development and implications for contemporary thinking. In short, thoughts and philosophy don't arise outside of historical context and maintain that context to the current day as explanatory device. But if you've not read the any Williams, i recommend it.
