Matter is real to my senses, but they aren't trustworthy. If Galileo or Copernicus had accepted what they saw, they would never have discovered the movement of the earth and planets.
The ecological movement is concerned about this, and this is in here, where everything is public. In Iran, where everything is covert, we have no firsthand information.
Sometimes it can seem that history is turning in a wide arc, toward an unknown shore. Yet the destination of history is determined by human action, and every great movement of history comes to a point of choosing.
Look not at what is contrary to propriety; listen not to what is contrary to propriety; speak not what is contrary to propriety; make no movement which is contrary to propriety.
