A balance has two ends: when one goes up, the other goes down. As a metaphor for living, it lacks dimension.
Homeostasis is better. It has no end, but it does count every factor. With a balance, it's possible to find a point where everything holds perfectly still – until the wind changes. With homeostasis, there is no still-point, because even the thing that pushes the wind is part of it. It's always shifting.
Homeostasis is a puzzle to which there is no lasting solution, only a series of adjustments. There's always something new to learn, something different happening.
I find that intriguing.
After living on the water, in the forest, by the desert, and in cities of all sizes, it also makes perfect sense to me. No change sets off only one corresponding change. All real things are clusters of changes, and in the end we can either adjust or be adjusted – and only one of those alternatives accounts for our own wishes.
Living, like homeostasis, is not about flattening the ocean. It's about riding the waves.
