…and splitting the logical difference.
1) Even those who have no map will stray from their destination if they turn back to a location which they know is not their goal and willfully ignore even the erroneous advice they were given before heading out.
If one genuinely wants to reach one’s destination, it would be a serious error to turn back or ignore one’s only guides. With nothing better to go by, one is still obliged to stay the path.
2) Even if people are on the wrong path, genuinely seeking their destination means deciding, based on perceived landmarks, how far and in which direction they ought to drive.
Without a good reason, it would be folly to ignore one’s surroundings and/or to abandon one’s progress so far, as if one were indifferent to arriving at the destination. At the very least one should not return to a location that is closer to the starting point than to the perceived destination.
3) These ongoing estimations and decisions constitute the accuracy or inaccuracy of anyone’s journey towards a goal.
We can know if someone made the correct decisions in terms of reaching one’s goal based on one’s persistent responsiveness to landmarks and a desire to reach that goal. Likewise, we can judge whether someone arrived at one’s destination simply by analyzing whether one maintained forward progress.
