You're right. It's definitely a sermon.
Human: a primate that builds a model of the universe inside its brain and upon physical maturity, moves a model of itself inside that model, avoiding reality at all costs.
The sermon is also about the habits, coercions and tortures of the modern human's model building circumstances. To paraphrase Douglas Adams, "Because models have got to be built!!"
Marketers get a tax deduction for manipulation of children's model building (religion is all marketing now, though God was once the marketing department for the town meeting), and so-called "adults" have been neotonized and branded in order to be proper consumptionists.
Braingasm: I just noticed a cookbook on Da Wife's shelf, "How to Cook Everything".
I'm thinking that our leadership has taken it too literally.
