Abstract
This chapter, which examines the conception of equality and women's freedom in the field of philosophy in Great Britain during the seventeenth century, analyzes the works of Margaret Cavendish, Duchess of Newcastle and Mary Astell, who wrote about feminist issues, the nature of liberty, and equality for women. The analysis of a variety of writings reveals that seventeenth-century women were politically aware, took an interest in political affairs, and were conscious of their position as women within the social and political order of their time.
