I think it's human nature to be interested in other humans--how they live, what makes them tick-- and compare ourselves, not necessarily with a critical slant but with curiosity. Looking at others inevitably makes us look at ourselves.
Another story this week supporting the concept of art, music and dance as instincts innate in the human spirit ran in the New York Times. Maybe you read it already-- Maurice Chammah, a staff writer at The Marshall Project, wrote an editorial about the history of prison music. Inmates singing, composing, performing. There's a long tradition of prisoner song, a beautiful and tormented one, but the takeaway from Maurice's eloquent essay is that this music helps more people than those behind bars, even if they-- we-- don't know it. I've linked to the piece below.
