Why would you want to rehash someone elses thoughts? Doesn't it make more sense to reform them with thoughts and ideas you already own. Perhap getting an 'If that and then... wouldn't this?' = a personal 'Aha'.
Really it is only going to happen if you think about another persons ideas, not memorise them. This is probably why a child loses their photographic memory, the visuals are integrated with imagination creating a multitude of personal memories, meanings and ideas.
