    Reasons For

    1 perspective
    Reason for
    ?
    • The celestial spheres move without passing through any resistant medium
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Motion requires a medium to determine direction and differentiate positions, as Aristotle argues in Physics IV: void is dimensionally undifferentiated.
      ?

      Think about whether this reason is strong or weak

    • 2.Without qualitative differentiation of positions, a body in void has no reason to move in one direction rather than another, making determinate motion impossible.

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Celestial spheres move through a plenum of aether, a fifth element posited precisely to serve as their medium, not through genuine void.
      ?

      Think about whether this reason is strong or weak

    • 2.Ibn Bājja's inference from celestial motion to void-motion possibility commits the fallacy of equivocation: 'no resistant medium' is not equivalent to 'no medium whatsoever'.

    Aristotle rejected the possibility of motion in the void because the medium was essential to natural movement at finite speed (Phys. IV.8). John Philoponus had already expressed the view that the medium is not a necessary condition, but only provides resistance. The different velocities with which the stone passes through the air or the water is only caused by the different density of the medium; it is not connatural to the medium. As a proof that motion without any medium, namely, through a voi
