A Narrative of the Life of Mrs. Mary Jemison

That to biographical writings we are indebted for the greatest and best field in which to study mankind, or human nature, is a fact duly appreciated by a well-informed community. In them we can trace the effects of mental operations to their proper sources; and by comparing our own composition with that of those who have excelled in virtue, or with that of those who have been sunk in the lowest depths of folly and vice, we are enabled to select a plan of life that will at least afford self-satisfaction, and guide us through the world in paths of morality. Without a knowledge of the lives of the vile and abandoned, we should be wholly incompetent to set an appropriate value upon the charms, the excellence and the worth of those principles which have produced the finest traits in the character of the most virtuous.
