" In every known culture,
humans experience joy, sadness, disgust, anger, fear, and surprise. In every
known culture, these emotions are indicated by the same facial expressions.
This empirical observation, which is predicted and mandated by the
structural logic of evolution, is known as the psychic unity of mankind. (I
prefer the term “psychological unity of humankind,” but I didn’t invent it.) "
