[de Silentio]

The 'metaphysical' interpretation includes the self as a participant in the chain of cause and effect.

Where does the self fit into the chain of cause and effect?

Another example is that a person notices that when he or she is angry they then have a tendency to bump into things. The 'anger' is included as a 'causal' event of the 'bumps'

I can see how this example relates to what you said about metaphysics, but this example is vastly different than the $5 or boulder examples that you gave. The former shows how a person’s will has control over their body, the latter shows how a person’s will has control over something physically detached from themselves.

The 'slits experiment' is only relevant in a remote type of way

Mundane physics has Man as an observer and metaphysics has Man as a participant/creator.

The slits experiment shows how our consciousness effects the physical world, how does that not show what you are saying? The experiment shows that man participates in how the photons act, if man is not watching, they act like a wave, if man is watching, they act like particles.

Mundane physics would only be aware (as an example of metaphysics) of what was going on between the screen with the slit(s) and the board. Metaphysics would attempt to discern what was going on behind the slitted screen where mundane physics did not investigate.

We know what is going on behind the screen, we are shooting photons at it. What we don’t know is what goes on between the screens, that why we try to observe it.

In what way does metaphysics attempt to discern what was going on behind the screen as opposed to physics?

Descartes (one interpretation) sees 'thought' as being the creative cause of his existence. He 'thinks himself' into being. Descartes is NOT... born of a woman (but was),.. but was, rather, delivered into 'beingness' by 'thought'.

Can you please explain to me how you extrapolated this from Descartes writings.
