How do our senses know when we’re free? It seems to run along a continuum, one that we define in relative terms. The playground is freer than the classroom, the picnic freer than the formal banquet. But at each end of the spectrum there are absolutes. On one end lie places we all agree are restrictive, like the tunnel of an MRI machine or a solitary-confinement cell. On the other are places that feel entirely unconstrained—fields and lakes, parks and beaches. As I thought about it, I realized that the most liberating places are, with few exceptions, found in nature.
