The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. ★ All great truths begin as blasphemies.★ Progress is impossible without change, and those who cannot change their minds cannot change anything.★ If you want to tell people the truth, make them laugh, otherwise they’ll kill you.★ Beware of the man who does not return your blow: he neither forgives you nor allows you to forgive yourself.★ The power of accurate observation is commonly called cynicism by those who have not got it.★ People who say it cannot be done should not interrupt those who are doing it.★ Do not do unto others as you would that they should do unto you. Their tastes may not be the same.★ The single biggest problem in communication is the illusion that it has taken place.★ A government that robs Peter to pay Paul can always depend on the support of Paul. ★ Democracy is a device that ensures we shall be governed no better than we deserve. ★ Science never solves a problem without creating ten more.
