Struggle often baffled, sore baffled, down as into entire wreck; yet a struggle never ended; ever, with tears, repentance, true unconquerable purpose, begun anew. Poor human nature! Is not a man's walking, in truth, always that: "a succession of falls"? Man can do no other. In this wild element of a Life, he has to struggle onwards; now fallen, deep-abased
 Thomas Carlyle, On Heroes, Hero-Worship, and The Heroic in History (1841). copy citation

Context

“David's life and history, as written for us in those Psalms of his, I consider to be the truest emblem ever given of a man's moral progress and warfare here below. All earnest souls will ever discern in it the faithful struggle of an earnest human soul towards what is good and best. Struggle often baffled, sore baffled, down as into entire wreck; yet a struggle never ended; ever, with tears, repentance, true unconquerable purpose, begun anew. Poor human nature! Is not a man's walking, in truth, always that: "a succession of falls"? Man can do no other. In this wild element of a Life, he has to struggle onwards; now fallen, deep-abased; and ever, with tears, repentance, with bleeding heart, he has to rise again, struggle again still onwards. That his struggle be a faithful unconquerable one: that is the question of questions. We will put up with many sad details, if the soul of it were true.” source
