We regard the features of separation which Ignotus delineates in the foregoing passage, as most highly commendatory of it as a means of discipline and reform. This better occupation of the mind and body, a more liberal diet, and the greater number of teachers, which become so needful, indicate just what the desire for wholesome food does in a convalescent patient. His vices had made wholesome occupation of either mind or body irksome; and the attempt to teach him good knowledge was to annoy, if not to offend him. If separation from the haunts and fellowship of the wicked makes him long for what he once loathed, the public are “penny-wise and pound-foolish,” if they grudge the supply. It is the token of returning health and should be hailed with joy and gratitude.
