In the preparation of this volume, all the more important Lincoln literature was carefully studied. Just as the white light from the sun, when passed through a prism of glass, reveals the seven primary colors of the solar spectrum, so the white light emanating from the soul of Abraham Lincoln, when passed through the prism of a sympathetic study of his words and deeds, reveals the seven primary virtues of his great character - humility, reverence, loyalty, honesty, simplicity, humor and magnanimity. To each of these a chapter is devoted.
