(my underline)For the FW thing to be the case, one must be able to demonstrate agency over seeming random events: I can consistently will the cat to be dead or alive before I measure it, or some such act.
Otherwise, the will is subject to dice rolling instead of deterministic physics, which sounds just as not-free. You sort of recognize this problem in your last post on the first page.
The so-called Free Will is uncaused, and if it existed a so-called Free Will event would be a truly random event that's to say a different sort of 'random' from dice- rolling which although unpredictable is caused.
Determinism on the other hand does allow for degrees of freedom (NB freedom is not a synonym for so-called Free Will). The degrees of freedom which Determinism yields depend upon inductive reasoning and accumulation of knowledge.Or to put the matter crudely, a wise man is more free than a fool.
