We are aware of other persons in many different ways. Our thoughts, feelings, or experiences may present another by image in a mental picture, by name as "Dagfinn Føllesdal" or "Virginia Woolf", by description as "the founder of cubism" or "the leader of the Cuban Revolution", or indexically as "you" or "she" or "he" or "they". But it is only in perception, especially in seeing "you" or "her" or "him", that we are acquainted with other persons.
