For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
There’s no such thing as tides. Gravity holds the water as the earth rotates
Tides are a phenomenon where the height of the edge of a body of water shifts relative to the shore. A phenomenon is a thing. Why should explaining its cause in those terms have any effect on that?
But aren’t the tides caused by external gravitational forces (the moon?)
the tides stay in the same place relative to the moon and the earth spins below the tidal bulges (earth spins faster than the moon orbits, is the basic thing)
I’m confused: you say there’s no such thing as tides, and then explain what tides are?
Tides are the waters going out and coming back. That is how we experience it. We experience it wrong.
That’s like saying sunrise doesn’t exist because the sun is relatively stationary while the earth revolves on its axis. Sunrise and tides are the names we give to how we experience these things.
Subjective experience cannot be wrong or right; it simply is. Interpretation of that experience can be wrong or right. Either way, the experience still happened.
