Scholars working on recovering forgotten historical women philosophers have noted the importance of looking beyond traditional philosophical genres. This strategy is particularly important for finding Scottish women philosophers. By considering non-canonical genres, we can see the philosophical interest of the works of Scottish poet and playwright Joanna Baillie (1762–1851), who presents an account of “sympathetic curiosity” as one of the basic principles of the human mind. Baillie's work is also interesting for being a rare case of a woman's philosophical work that was discussed in print by another woman philosopher – in this case, by Elizabeth Hamilton (1758–1816), who argues for the importance of a feature of human nature that she calls the “selfish principle.” The article suggests that focusing on critical engagements between historical women philosophers can help integrate their texts into the history of philosophy without presenting them as “handmaidens” to male philosophers.
