After all, Woolman's trouble and sorrow and tumult of spirit, so suggestive, so helpful to modern souls, were transitory. At the heart of his "endless agitation" subsisted a "central peace." His was the grace to know that "deep humility is a strong bulwark," and to "look less at the effects of the labour than at the pure motion and reality of the concern." The gentleness with which he delivered his fiery message was more than a manner due to Quaker training, or even than a result of resolute self-discipline: it was the index of an inward stillness in which his soul dwelt undisturbed. Let us hope that the days may come when the "concern" about profiting by the painful or degrading labour of others will have an interest as exclusively historic as the "concern" about holding slaves has already attained. Tremulously it may be, yet soberly and joyously, many clear-minded and practical people are beginning to hope for such a day. When it comes, the immediate message of Woolman will be less cogent, but he will still continue to be read by those who care for the revelations of a beautiful soul. These pages offer more than light on the path of social duty; they offer fellowship with a spirit that "dwelt deep," and attained an abiding loveliness because responsive through all turmoil of spirit and all outward suffering, to the "gentle movings of Uncreated Purity." "That purity of life," wrote he, "which proceeds from faithfulness in following the Spirit of Truth, this habitation has often been opened before me as a place of retirement for the children of the light, where we may stand separated from that which disordereth and confuseth the affairs of society." Such a "place of retirement for the Children of the Light," this book affords. VIDA D. SCUDDER. BIBLIOGRAPHY
