Critique of Pure Reason, Part III

If at first you don't succeed, try try again.

There was this dude who tried to go over Niagara falls in a barrel and live to tell the tale. His barrel broke right before he got to the falls, and he went over as just himself, you know, without the barrel. He broke seventeen bones and almost drowned and had to have prosthetic eyebrows put in because his real ones had lodged below his cheeks. So he got to tell the tale, but he didn't really quite accomplish the deed itself. So a year later he went back, and this time he accomplished the deed, only he died before he got to tell the tale.
