Okay, so I know that each door has to lead somewhere, which means that somewhere at the place we're trying to go there must be a reverse door that leads here. And that, in turn, means that our destination corresponds with the counter-inverted reverse door's origin! So starting from the right, let us ask: will taking the right door lead us to where we're going? And since the answer is clearly 'yes,' then by all accounts, the door on the right is the correct one! Another victory for logic. Come, Stanley, our destiny awaits!
