This is where I think out loud:
Humanness
The condition of being permeable to a world that's real. The capacity to be affected by beauty and by loss, to need other people as witnesses, to stay present at the edge of what you know.
Permeability
Staying open to what's real, even when it costs something. Grief moves through you, beauty catches you off guard. It's the opposite of the armor most systems ask us to wear.
Infrastructure
The systems a society builds to hold up the things it decided are important. Hospitals for sickness. Schools for learning. Roads for getting places. Nothing like this exists yet for humanness.
