All important thinkers tend to have followers and disciples as well as intellectual opponents, both of whom try to define the thinker’s thought in particular ways. In itself, this is normal, neither to be deplored nor applauded. Any thinker who produces writings is like someone on a ship who throws overboard a glass bottle with some text inside. Once he has thrown it overboard, he can no longer control where the seas will take it, who will claim to own it, who will pick it up and change it, who will try to destroy it or hide it. It is well known, and often repeated, that Karl Marx, referring to the so-called Legal Marxists, said ‘what is certain is that I’m not a Marxist!’1
