It occurred to me that perhaps the word "integrity" comes as close as any singleword answer to, "What is Quakerism?"

If integrity is to serve as a shorthand way of describing the essence of Quakerism, it must find its root in the context of Quaker history. I want to unearth that root in the remainder of this essay.
