Mr. Andre Reflection

I found Mr. Andre's presentation to be rather interesting. I found the whole gist of the presentation to be that a puzzle can only be solved if you have every part of the puzzle; sometimes there is no way to know what fact will make the difference because there is no way to know each's importance to the puzzle as a whole. The riddles further reinforced the idea; if you can't see the whole picture there's no way of knowing the answer.
