  For example, in The Fragility of Goodness Martha Nussbaum has described the virtues of an Aristotelian ethics with its emphasis on the importance of concrete context, emotion and care for others in an ethical life (Nussbaum 1986). And Marcia Homiak has argued that Aristotle's rational ideal, far from being antithetical to feminists, actually captures some of feminism's deepest ethical insights (Homiak 1993). With regard to Descartes, Margaret Atherton has argued that his concept of reason was interpreted in egalitarian rather than masculinist terms by several women philosophers of the 18th century, and was used in their arguments for equal education for  women.[11]
