 During the following several years Schleiermacher complemented On Religion with two substantial publications that were more ethical in orientation: the especially important Soliloquies (1800; second edition 1810) and the Outlines of a Critique of Previous Ethical Theory (1803). In 1800 he also defended his friend Friedrich Schlegel’s controversial and arguably pornographic novel Lucinde from the same year in his Confidential Letters Concerning Friedrich Schlegel’s Lucinde—a shared feminism constituting a large part of his reason for sympathizing with Schlegel’s book. During the period 1799–1804 Schleiermacher developed with Schlegel the project of translating Plato’s dialogues. As time went on, however, Schlegel left this work to Schleiermacher, which contributed to increasingly difficult relations between the two men after 1800. Schleiermacher’s translations appeared during the period 1804–28 (though not quite all of the dialogues were translated in the end), and are still widely used and admired today.
