Questio de aqua et terra (65)

(65) Hec eadem ratio removet ab hac causalitate aerem et ignem; et cum non restet ulterius nisi celum, reducendus est hic effectus in ipsum, tanquam in causam propriam. (65) This same argument rules out air and fire from this causation. And since there is nothing left save heaven; this effect must be referred to it, as to its proper cause.
