 Even closer parallels have been noted between the ten commandments section of Life of Soul and the corresponding section of the compendious tract called Poor Wretch (Pore Caitif).The material is very traditional, and a common source may well be involved, but some connection is demonstrable from the often verbatim correspondence.Finally, it is hard to avoid comparison of Life of Soul with the idiosyncratic and personal treatise called Book to a Mother.
