This book is the most mature and comprehensive statement of Mary Astell’s religious and philosophical views. It also represents the culmination of Astell’s feminist project to teach her fellow women how to lead useful lives of virtue and wisdom. The main purpose of this work is to instruct women about the ultimate nature of reality, the true source of happiness, their duties and obligations to God, and about “how best to live” and how to treat other people. This volume offers the first complete modern version of the 1717 second edition. It provides a fully modernized text, a scholarly introduction, biographical and bibliographical information, general historical-intellectual background, and definitions of obscure and archaic terms.

Published anonymously in 1700, Some Reflections upon Marriage lamented the inequities of the institution of marriage and reasoned against it with both traditional and innovative arguments. Mary Astell's tract, written in response to an infamous divorce case, forcefully argued against the grim but all-too-common prospect of a marriage of necessity to a man in search of power, money, or a trophy wife. Astell proposed education as the solution to women's second-class status, stating that knowledge alone could lead to a partnership based on friendship and respect. "Let us learn to pride ourselves in something more excellent than the invention of a fashion," she wrote, and her well-reasoned arguments soon won her a wide readership.
