William Henry Furness was an American clergyman, theologian, Transcendentalist, abolitionist, and reformer.

Transcendentalism is a philosophical, spiritual, and literary movement that developed in the late 1820s and 1830s in the New England region of the United States. A core belief is in the inherent goodness of people and nature, and while society and its institutions have corrupted the purity of the individual, people are at their best when truly "self-reliant" and independent. Transcendentalists saw divine experience inherent in the everyday, rather than believing in a distant heaven. Transcendentalists saw physical and spiritual phenomena as part of dynamic processes rather than discrete entities.
