There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope.

Mark TwainThe people of those foreign countries are very, very ignorant. They looked curiously at the costumes we had brought from the wilds of America. They observed that we talked loudly at table sometimes. They noticed that we looked out for expenses and got what we conveniently could out of a franc, and wondered where in the mischief we came from. In Paris they just simply opened their eyes and stared when we spoke to them in French! We never did succeed in making those idiots understand their own language.
