Amour-de-soi is the joy you feel when singing in the shower. Amour-propre is the joy you feel while singing at Radio City Music Hall. You may sing poorly in the shower but the delight is yours alone, independent of others’ opinions, and therefore, Rousseau argued, more authentic. So you can see why Rousseau walked. Walking requires none of the trappings of civilization: no domesticated animals, no carriages, no roads. The walker is free, unencumbered. Pure amour-de-soi.
