The great science fiction writer Robert A. Heinlein was one of my first favorite writers, back when I started reading his juvenile fiction when I was about 12 or 13. I had no idea that he had already arrived at some of the conclusions it would take me decades to find.
There’s a widely held belief that Heinlein was a libertarian, but that’s much more complicated than most people think. He was pretty much an outright socialist in the early decades of his life, then a hardcore cold warrior after that. Still, libertarian themes emerged, most famously in “The Moon is a Harsh Mistress.”
Whatever he was in the early parts of his life, he gave us some of the best literary efforts on ideas related to freedom. I was reminded of that earlier this week when I saw this quoted, which comes from “The Notebooks of Lazarus Long“:

Learning to be an emotional man helped me to overcome numb past
Industrial age relic: Do companies pay for your time or your brain?
Widow: ‘Things that mattered yesterday do not matter today’
Why do so many of us stay where we know we’ll remain miserable?
Shock of seeing ‘Airplane!’ was realizing that I wasn’t all alone
Old photos have me thinking about who I was then, how far I’ve come
Opinions without fact or reason leave us believing in nonsense
Hurt people hurt people, and it’s hard to forgive that in ourselves
The things we regret the most show us what we really value
