 4) Avempace (d. 1138) had his own view on the issue. The sphere is not in place because nothing encloses it from outside. “The place of the sphere that is envisioned by this, in so far as it is sphere, is the convexity of the center, around which it rotates” (LC 142A T43). Avempace would take Aristotle’s definition of place as that which surrounds the body and apply it to the external surface of the bodies moving rectilinearly and to the internal surface of the bodies rotating. Averroes conjectures that Avempace borrowed his view from al-Fārābī (d. c. 950) who refuted the opinions of Johannes Philoponus on place but al-Fārābī’s book “did not fall into our hands”, he says.
