…let’s explore the origin of our first translated quote. This will set up an exploration of your personal language later in Chapter 7. The literal translation from long ago, in a much different world, is something like, “But the unexamined life is not lived by man.” Scholars render it today as, “The unexamined life is not worth living,” but it could also translate to, “For a human being, a life without introspection is not truly lived,” or more succinctly, “Life without reflection is not fulfilling.” This underscores that quotes originate from the mind of a specific person in a specific culture with their own contextual background and origin story.
