I never heard of him until now, thanks for sharing! In reading about him it would appear he was a man of his time. He influenced Nietzsche so there you go. People say he influenced Nazism but that's kinda an empty argument.
I bet Hitler cried himself to sleep (genocide will do that to you). But thanks for introducing me to someone I never heard of, like your other posts. Keep up the good work.I came across the reference quoted in the blog post in a history book that I am reading. The authors stated that John Duncan hated Thomas Carlyle's philosophy for the same reason that Adolf Hitler loved it. So, I do not think that we should dismiss the argument as a complete reductio ad Hitlerium - especially as Carlyle's racial prejudices were very strong.
