[One may dispute these nested formulations. Perhaps, one can claim that the thought experiment should be left out of the picture. However, to me, that runs against a key observation: Choice and the something that can be chosen are two independent actualities.
So, the thought experiment where ‘I choose something’ became a model.
This is not the only way to approach Schoonenberg’s difficult and condensed text. It is the route that I explored.]
