My interview with Rich Lewis of Silence Teaches Us Who We Are... 

Excerpt:  "What is significant about the contemplative mysticism of Fox and the early Quakers is how it caused them not only to go inward but also to then look outward and become radical change-agents in their culture: speaking out and activating against slavery, against war, against injustice and unfair social norms, etc., but from a place of contemplative centeredness.  I see a similar trend in modern times with the 'Engaged Buddhism' of Thich Nhat Hanh."
