TLS, one page, 8 x 10.5, Prime Minister’s House letterhead, August 15, 1967. Letter to Senator Ralph Yarborough. In part, “I am glad to know that a commemorative stamp has been issued to mark the 150th birthday of Henry David Thoreau…Thoreau’s thought made a profound impression on another seeker of truth, Mahatma Gandhi. Gandhi…developed the the idea of resistance to authority…He coined the Sanskrit work ‘Satyagraha’ to describe this movement. At that time he happened to read Thoreaus’s great essay and he adopted the phrase ‘Civil Disobedience’ to explain the spirit of his movement to English readers. Through Gandhi, Thoreau’s thought has had an impact on our own thinking.” In fine condition. Accompanied by the original mailing envelope. R&R COA.
