George Bernard Shaw;
"All progress is initiated by challenging current conceptions, and executed by supplanting existing institutions"
"Common sense is instinct. Enough of it is genius"
"Life is no brief candle to me. It is a sort of splendid torch which I have got a hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations"
"The reasonable man adapts himself to the world. The unreasonable one persists in trying to adapt the world to himself. Therefore all progress in the world depends on the unreasonable man"
"The more things a man is ashamed of, the more respectable he is"
