I try to read John Woolman's Journal once a year...

From American Friends Service Committee:  "Ahead of most others in his time, John Woolman took courageous ethical positions as an advocate for justice for the poor, the enslaved, and the oppressed native peoples of North America. To Quaker activists today, his writings offer a way to stand strong in one’s convictions yet work gently with others to persuade them to change. ... John Woolman’s influence extended beyond his life and beyond the Religious Society of Friends. He inspired later abolitionists, proponents of simple living and ecologically based values, advocates of war-tax resistance, and champions of social justice. A multitude of readers continues to be moved by the gentleness and striking degree of self-honesty and integrity in his 'Journal.'”
