Tautological. To know the way I must first know the way.
Let's say I want to go to place X, but I don't know where place X is. I could get maps or ask directions to X. I could strike out blindly in a direction, though. If I do the latter, the descriptive term for my journey in relation to getting to place X would be lost -- even if I'm headed in the right direction. But, if I'm also a ranger, I cannot be lost, so I must therefore, according to your tautology, know the way!
The tautology you propose hasn't been ignored by me at all. It's the core of the argument. Thanks for pointing it out again!
Seems like a wrong turn to take the pass, then, doesn't it?
