Professor, web entrepreneur Denis Dutton dies. Readers of this weblog probably know him for Arts & Letters Daily and The Art Instinct. I never knew the man personally, but he made an impact on me through his website and articles. We shared friends, and I was proud when Arts & Letters Daily put this website on its blogroll, and sent us the occasional link. For me blogging is about ideas, not people, but when someone passes on those ideas are made flesh.
