Thinking

Mark Twain: “It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt”.

And again: "Good breeding consists in concealing how much we think of ourselves and how little we think of the other person."

And lastly: "In religion and politics people's beliefs and convictions are in almost every case gotten at second-hand, and without examination."

How true. I stand corrected.
