For the impossibility of a void has been made quite certain in the philosophical sciences. For that upon which the name void is commonly applied, are nothing but dimensions (_Abad_), in which there are no bodies. For when these dimensions are once removed, there remains nothing but non-existence. But if the void be supposed as existent, it is necessary to admit the existence of accidents in something not a body, for dimensions are accidents by their having a quality. But it is said by the Ancients and established by past religions that that place is the dwelling place of the spirits, God and angels. This place has no space, and is not governed by time, because everything governed by time and space can be corrupted. And it is necessary that the things there be uncorrupted and uncreated. This has been made quite clear by what I have said, for there cannot be found in that place anything but one which is existent and at the same time can be felt, or is altogether non-existent. It is self-evident that an existent object is always referred to by its existence; that is, it is said that it exists, that is, it has an existence. So if anything exists there, it must be the noblest of all, and it is necessary that that existent thing should be referred to by the best portion of the universe, which are the heavens. God has said concerning the nobility of the heavens, “Verily the creation of heaven and earth is more considerable than the creation of man: but the greater part of men do not understand.”[86] All this is perfectly clear to the learned men “Well grounded in knowledge.”[87]
