  A similar strategy for incorporating women into the philosophical canon can be used with respect to such central topics as the Principle of Sufficient Reason (Emilie du Châtelet), free will (Cavendish, Damaris Masham, du Châtelet), and cosmology (Cavendish, Anne Conway, Masham, Mary Astell, du Châtelet; see Lascano (forthcoming)). The SEP entry on du Châtelet contains a helpful discussion on her position on the Principle of Sufficient Reason, as well as an array of secondary sources. The SEP entries on Cavendish, Masham and du Châtelet provide some detail as to their positions regarding free will.
