Using the metaphorical (or maybe literal) model of ideas as living things - there should be conditions we can create to nurture an ecosystem of beneficial ideas. Like making a garden or farm.
Not just thinking about transmission method (memes, books, songs, art, gatherings) but also having a defined, intentional and continued program of evaluating ideas and spreading ideas.
I have nothing useful to contribute. Just, lately, been thinking a lot about platonic ideals. Plato decided that… so, chairs. There are office chairs, camping, some metal, some wood, variety. Plato said that any chair you see, it is an imitation, an attempt. But the CHAIR ideal existed separately, in its own realm. At one point he theorized it was at the top of our existence, our reality.
An abstract homunculus, if you will. Mankind’s capacity for abstract thought is astonishing, we use it to put rocket ships in space, math, science. Etc. But humans can get so caught up in their abstract thinking, they can lose touch with actual reality. People become labels, wars are fought over imaginary gods, anything can be justified.
Abstract thought can be tricky.
