To take revenge on a book – a weak thinker wonders how he can take revenge on a book of strong thought. How is this possible? In the feeling of vindication that arises from taking issue with this or that argument – which already assumes, beforehand, that the book can be cut down to a sequence of discrete arguments whose arguments can be tested and found wanting. How, then, do you meet a strong book? How do welcome it? It is a question of finding its orientation and following it, of leaning with it into the wind.
