Depends on the Definition of Sanity
Was reading a biography of convert/priest Isaac Hecker over the weekend and it says that when he was still and praying he longed for activity and mission, but when he was working he longed to be still and prayerful. Alas, the human condition in a nutshell.
There was also a blurb about how he had a "breakdown", then "common among 19th century idealists". Lots of madness in the Romantic era. I guess in some ways we're more sane but also more at the risk of living in Brave New World-ish comas.
