Mary Baker Eddy’s primary work, Science and Health with Key to the Scriptures, is a 700-page book detailing her discovery of Christian Science, her system of healing, and her commentary on the Scriptures. It was the focal point for the expression of so many of Eddy’s ideas. “That work is the outgrowth of my whole life, as my dear husband used to say,” she wrote to a student.

First published in 1875, Science and Health has sold over 10 million copies and is a best-seller today.

Following a serious accident, Eddy had a profound healing experience that provided important insights into the spiritual nature of life and health—insights which she had been seeking for many years. She later called that experience a “discovery” and soon sought to understand, replicate, make notes on, and teach this discovery to students and patients. As Eddy’s ability to prove the effectiveness of her discovery grew, she established herself as a healer and began to teach others how to heal. In 1868, she was asked to help a woman dying from pneumonia. The doctor in attendance had informed her that there was no hope for the patient, but Eddy immediately cured the woman. The doctor urged her to write a book about her system of healing and share it with the world. Science and Health is the result.
