> essentially all knowledge
In one particular European tradition, maybe? But elsewhere the trickster may themselves be a divine source of insight. Hermes in Greek, the Southwest American Kokopelli, etc.
My point is that the trickster as philosophical root is an idea that has tendrils far beyond a Western viewpoint. I cant find the ref now but IIRC some Native American traditions have the viewpoint that connecting to the divine cannot be made without first laughing, as that opens the mind to the new experience. Reminds me of some Far Eastern traditions where you need a sharp break from your normal world view to achieve an enlightening breakthrough.
