There's a metaphor worth exploring for understanding how certain kinds of people process experience — the people we sometimes call sages, teachers, or wise elders. It comes from biology, of all places.
The tree as a model
A tree is a negentropy machine. It takes in raw, disordered inputs — sunlight, carbon dioxide, water, minerals — and produces something ordered: wood, leaves, fruit. It gives back more structure than it takes in. Something similar happens in the mind of a person processing experience well. They take in raw, often painful inputs and over time metabolise these into something ordered: understanding, perspective, wisdom.
What makes the sage different
Most people process experience well enough to function. The specific thing that characterises the sage type is that they process to surplus — they generate more understanding than they need for themselves. Like a tree producing fruit it can't consume, the sage produces insight that it has to give away. Understanding that isn't communicated somehow feels incomplete.
The problem of rejection
Trees produce fruit whether or not anyone comes to eat it. The sage's situation is more complicated: the people most in need of what they've worked out are often the least ready to receive it. Insight delivered before someone is ready doesn't land — it irritates.
This is one of the less discussed costs of developing genuine understanding: you can see things coming that others can't, and there's almost nothing you can do about it except wait and remain available.
