Again, the healers of our bodies will have their labours and vigils and cares, of which we are aware; and will reap a harvest of pain for themselves from the distresses of others, as one of their wise men said; and will provide for the use of those who need them, both the results of their own labours and investigations, and what they have been able to borrow from others: and they consider none, even of the minutest details, which they discover, or which elude their search, as having other than an important influence upon health or danger. And what is the object of all this? That a man may live some days longer on the earth, though he is possibly not a good man, but one of the most depraved, for whom it had perhaps been better, because of his badness, to have died long ago, in order to be set free from vice, the most serious of sicknesses. But, suppose he is a good man, how long will he be able to live? Forever? Or what will he gain from life here, from which it is the greatest of blessings, if a man be sane and sensible, to seek to be set free?

But we, upon whose efforts is staked the salvation of a soul, a being blessed and immortal, and destined for undying chastisement or praise, for its vice or virtue,–what a struggle ought ours to be, and how great skill do we require to treat, or get men treated properly, and to change their life, and give up the clay to the spirit. For men and women, young and old, rich and poor, the sanguine and despondent, the sick and whole, rulers and ruled, the wise and ignorant, the cowardly and courageous, the wrathful and meek, the successful and failing, do not require the same instruction and encouragement. — Paragraph 27 and 28.
