My dissertation advisor and friend, Tony Brueckner, recently died after a short illness. He was an outstanding philosopher. More importantly, he was an affable, generous, humble, and kindhearted person. Like so many others, I benefited tremendously from having him as a mentor. I'm grateful for the opportunity to work with such a clear-thinking and careful philosopher and I feel very fortunate to have developed a friendship with such a fun, kind, and gentle person.
