When I think of 'passion', I think of creating things, making things better, doing something that can bring me into a state of flow. I'm not an avid gardener, but I can absolutely see how gardening would tick those boxes for someone who was.
You're right. My father was a gardener, so I should have known better than to feel that way. I saw him prepare the soil, sow the seeds, and give the plants the support they needed to thrive over time. Thinking about the process of gardening makes me understand how it could be a passion. What about the classes of passion? Can gardening be put on the same level as art? Why or why not? They certainly at least have a different pace about them. A painter can work quickly, but a gardener must have such patience. Obviously a painter also must have patience with the process as well. I would like to think of this in a more mathematical way. This idea that in the space of gardening there are certain operations and objects that are distinct from, let's say, the domain of music. When you look at it that way, what is the character of the constructive mathematics being done in these spaces? This is now apparently liberal arts news.
