The daughter of philosopher Ralph Cudworth and a contemporary of John Locke, Masham wrote about knowledge and God, and the condition of women. Masham's work led Penaluna to other women philosophers: Mary Astell, who made a living writing philosophy; Catharine Cockburn, a philosopher, novelist, and playwright; and the better-known Mary Wollstonecraft, who wrote extensively in defense of women's minds. Together, these women rekindled Penaluna's love of philosophy and awakened her feminist consciousness. In How to Think Like a Woman, Penaluna blends memoir, biography, and criticism to tell the stories of these four women, weaving throughout an alternative history of philosophy. Funny, honest, and wickedly intelligent, this is a moving meditation on what philosophy could look like if women were treated equally.
