““One might wonder how on earth learning came to be seen primarily a result of teaching. Until quite recently, the world’s great teachers were understood to be people who had something fresh to say about something to people who were interested in hearing their message. Moses, Socrates, Aristotle, Jesus—these were people who had original insights, and people came from far and wide to find out what those insights were. One can see most clearly in Plato’s dialogues that people did not come to Socrates to “learn philosophy,” but rather to hear Socrates’ version of philosophy (and his wicked and witty attacks on other people’s versions), just as they went to other philosophers to hear (and learn) their versions. In other words, teaching was understood as public exposure of an individual’s perspective, which anyone could take or leave, depending on whether they cared about it. No one in his right mind thought that the only way you could become a philosopher was by taking a course from one of those guys. On the contrary, you were expected to come up with your own original worldview if you aspired to the title of philosopher.””
