None climbs so high as he who knows not whither he is going.

Our reading
An editorial interpretation.
The saying connects an unusually high climb with uncertainty about the destination. Its paradox can suggest that not knowing one's limits leaves room to rise beyond expectations. Yet the absence of a clear direction also complicates the achievement, making height and purpose seem like different measures of success.
