Now, I believe I've already made my views on the matter quite clear. But check out this awesome exchange between Gil Harman and Tom Hurka:
Harman: "More ageism."Oh man. So awesome. Hurka--you interested in a little guest blogging? Call me.
Hurka: "Ageism? Balls. It's about reducing the huge inequality between an age-cohort that's had it extremely good (those hired in the 1960s) and an age-cohort that are going to find it very tough (those now coming onto the job market). Or do we just say the latter group can go to hell?"
