" In acting and speaking, men show who they are, reveal actively their unique personal identities and thus make their appearance in the human world, while their physical identities appear without any activity of their own in the unique shape of the body and sound of the voice. This disclosure of “who” in contradistinction to “what” somebody is—his qualities, gifts, talents, and shortcomings, which he may display or hide—is implicit in everything somebody says and does. "

― Hannah Arendt , The Human Condition
