That's actually not a bad analogy, except for the tacit implication that RFK is a crackpot and not worthy of serious consideration. I, of course, agree with that. However, the sad fact of the matter is that RFK is the United States Secretary of Health and Human Servivces. He was appointed to that position by a democratically elected President and confirmed by a democratically elected Senate (or at least as close to democratically elected as it gets in the USA). So dismissing RFK as a crackpot is a no-true-scotsman fallacy. Like it or not, RFK is part of the biology establishment. In fact, he is one of the principal leaders of the biological establishment. The only difference between RFK and philosophers is that RFK is a recent and, hopefully, temporary aberration, whereas philosophy is shot through-and-through with RFKs and has been for thousands of years.
