It is in vain that a man of sound mind and cool temper understands the condition of such a wretched being, in vain he counsels him. He can no more communicate his own wisdom to him than a healthy man can instil his strength into the invalid, by whose bedside he is seated.

Context

“observe a man in his natural, isolated condition; consider how ideas work, and how impressions fasten on him, till at length a violent passion seizes him, destroying all his powers of calm reflection, and utterly ruining him. "It is in vain that a man of sound mind and cool temper understands the condition of such a wretched being, in vain he counsels him. He can no more communicate his own wisdom to him than a healthy man can instil his strength into the invalid, by whose bedside he is seated." Albert thought this too general. I reminded him of a girl who had drowned herself a short time previously, and I related her history. She was a good creature, who had grown up in the narrow sphere of household industry and weekly appointed labour;” source
