Every intellectual has a very special responsibility. He has the privilege and the opportunity of studying. In return, he owes it to his fellow men (or 'to society') to represent the results of his study as simply, clearly and modestly as he can.

Anyone who cannot speak simply and clearly should say nothing and continue to work until he can do so.
