Ptolemy Tompkins said this quote

“ But you know, there's a difference between thinking something and feeling something. I don't know whether I ever thought an answer like that was true before. I might have. But I never felt it. And I guess what that means is that if you haven't felt something, you don't know it.''That reminds me of something a poet called Kabir said once,' I said.... 'He said, 'Nothing that hasn't been experienced is true. ”
