Digging deep into Rorty for the past couple of days. Here's a quote from his book Philosophy and the Mirror of Nature wherein he recalls T.S. Kuhn and his take on science. The context is the distinction he makes between 'normal' science and 'revolutionary science'.
When reading the works of an important thinker, look first for the apparent absurdities in the text and ask yourself how a sensible person could have written them. When you find an answer, .... when these passages make sense, then you may find that more central passages, ones you previously thought you understood, have changed their meaning.Makes sense. But certainly not when you are in that 'un-understandable phase of reading'!
