Gentlemen, it is a fact that every philosopher of eminence for the last two centuries has either been murdered, or, at the least, been very near it, insomuch that if a man calls himself a philosopher, and never had his life attempted, rest assured there is nothing in him; and against Locke’s philosophy in particular, I think it is an unanswerable objection (if we needed any) that, although he carried his throat about him in this world for seventy-two years, no man ever condescended to cut it.
