"Quakerism was one of the many religious sects born in the seventeenth century under the influence of Puritan thought. The foundation principle of the Reformation, the right of private judgment, the Quakers carried out to its logical conclusion; but they were people whose minds had so long been suppressed and terrorized that, once free, they rushed to extremes. They shocked and horrified even the most advanced Reformation sects by rejecting Baptism, the doctrine of the Trinity, and all sacraments, forms, and ceremonies. They represented, on their best side, the most vigorous effort of the Reformation to return to the spirituality and the simplicity of the early Christians. But their intense spirituality, pathetic often in its extreme manifestations, was not wholly concerned with another world. Their humane ideas and philanthropic methods, such as the abolition of slavery, and the reform of prisons and of charitable institutions, came in time to be accepted as fundamental practical social principles."
