One of the major New Thought writers to seek healing at the hands of Phineas Quimby was Warren Felt Evans.

Warren Felt Evans contribution to New Thought came in the form of literature about this extraordinary rediscovery of health, healing, prosperity and transformation.

He was a farmer's son, a descendant of John Evans of Roxbury, Massachusetts, born to Eli and Sarah Edson Evans at Rockingham, Vermont, on December 23, 1817, the sixth of their seven children. He studied at Chester Academy and in 1837 entered Middlebury College. In 1838 he transferred to Dartmouth College at Hanover, New Hampshire, as a sophomore, but left in the middle of his junior year to become a Methodist minister. He served eleven different charges in that denomination. He married M. Charlotte Tinker on June 21, 1840, and continued his Methodist ministry until 1863, when he left that church and joined the Church of the New Jerusalem (Swedenborgian), having somewhere along the way begun to read the works of the great Swedish seer, Emanuel Swedenborg, and been converted to the truth of his doctrines.

But before this he had contracted a serious illness, "a nervous affection, complicated by a chronic disorder." He got no help from physicians or their medicines. How he first heard of Quimby is not known, but the fame of the good Portland healer had spread throughout New England through patients he had healed and through articles in the public press concerning his amazing healing powers without benefit of any physical remedy. In any event, Evans appeared in Portland in 1863. Mary Baker Eddy, then Mrs. Patterson, had come there, as had the Dressers in 1862. Evans, like them, found healing in the philosophy and methods which Quimby employed and taught, and became a devoted disciple, as did the others. He visited Quimby a second time, felt that he understood the philosophy and method, and told the Doctor that he thought he, too, could heal. Quimby encouraged him to do so, with the result that he began the practice of mental medicine at Claremont, New Hampshire.

In 1867 he opened an office in Boston and for more than twenty years, with his wife, practiced and taught informally the principles of mental healing. For years they received patients in their own home, in Salisbury, where they had moved in 1869. No charge was made for their services or instruction beyond free will offerings, and no one, however poor, was ever turned away. But he created no institution to perpetuate his teaching. He died 1889.
