“This March, in recognition of Women’s History Month, the OUP Philosophy team will be celebrating Women in Philosophy. The philosophy discipline has long been perceived as male-dominated, so we want to recognize some of the incredible female philosophers from the past including Simone de Beauvoir, Mary Wollstonecraft, and Hannah Arendt, plus female philosophers doing great things in 2018 like Martha Nussbaum, Clare Chambers, and Kate Manne.”
