An Honest Intention of Walking On
If you were walking across a plain, had an honest intention of walking on, and yet kept regressing, then it would be a desperate matter; but since you are scrambling up a cliff, about as steep as you yourself are if seen from below, the regression can only be caused by the nature of the ground, and you must not despair.
Franz Kafka, in 'The Zurau Aphorisms (14)'
