 For Hamann, knowledge is inseparable from self-knowledge, and self-knowledge inseparable from knowledge of the other. We are visible, as in a mirror, in each other; “God and my neighbor are therefore a part of my self-knowledge, my self-love” (N I, 302:16–23). He writes in a letter: “Self knowledge begins with the neighbor, the mirror, and just the same with true self-love; that goes from the mirror to the matter” (ZH 6, 281:16–17). Sometimes this exploration of self-knowledge through interpersonal intimacy takes a sexual form, as in the Sibyl’s Essay on Marriage (already discussed).
