The key to any progress is to ask the question Why? All the time. Why is that child poor? Why was there a war? Why was he killed? Why is he in power? And of course questions can get you into a lot of trouble, because society is trained by those who run it to accept what goes on. Without questions we won’t make any progress at all.
