There is a discontent that is fundamental to creation. After all, if what exists was enough, then why create anything? The wide variety of human personalities (on a long timescale) and moods (short timescale) is nothing less than Nature performing a great Search. What She is searching for is unknown, past mere survival. It makes sense to me to place that discontent in the context of a broader survival, the survival of the species, long-term. Something that other life cannot contemplate or work towards, but we can. And insofar as we are embedded in an ecosystem, it means protecting Life on Earth, and also spreading it beyond Earth. Lives well lived, quietly, like this man's, are both a triumph and a dead-end, simultaneously. It seems reasonable that a wide diversity of lives are needed and wanted by nature, or we wouldn't have them, and all of them are useful in their way.
