“At the time we were all convinced that we had to speak, write,and publish as quickly as possible and as much as possible and that this was necessary for the good of mankind. Thousands of us published and wrote in an effort to teach others, all the while disclaiming and abusing one another. Without taking note of the fact that we knew nothing, that we did not know the answer to the simplest question of life, the question of what is right and what is wrong, we all went on talking without listening to one another.”
