" What is the point? We assume that every time we do anything we know what the consequences will be, i.e., more or less what we intend them to be. This is not only not always correct. It is wildly, crazily, stupidly, cross-eyed-blithering-insectly wrong! "

― Douglas Adams , The Ultimate Hitchhiker's Guide to the Galaxy (Hitchhiker's Guide to the Galaxy, #1-5)
