@raphy31,
Quote:What is the mystery of Metaphysical Freedom? You can refer to Peter van Inwagen.
But why would you need to ask what it is if you already know where to seek? Van Inwagen's paper is self-elaborating and offers a synoptic account itself to what the expression refers. If it was instead evaluations or opinions, potential solutions, etc., that you were requesting -- then even that can sometimes stimulate the saboteur impulse in those suspicious of homework assignments being farmed-out to the internet -- should it blatantly stand out as other than merely personal interest / hobby. (I.e., "But the wooden horse appears so sound in structure, even if a charitable gift of the Greeks. Why not utilize it?!").
