It's very exciting for all of us at the Soup, and a true honor for me, to introduce T.M. Scanlon as this week's featured philosopher. Tim certainly needs no introduction to the PEA Soup crowd, as his work in moral philosophy has been truly agenda-setting. Therefore, I think I'll simply get out of the way, and let his post---which begins below the fold---speak for itself. Without further ado, then, please welcome T.M. Scanlon!
