 If we pay attention to ourselves [as thinking things], we will find that we are conscious of many things outside ourselves. However, we set them apart from us in that we recognize that they are distinguishable from us, just in the same way as they are set beside each other, we recognize they are distinguishable from each other…. In that there are many things now which exist at the same time and which are presented apart (and yet at the same time different) from each other, such things come into being under a certain order. And as soon as we perceive this order we perceive space. Therefore, if we do not want to examine the matter differently than we recognize it, we must assume space is the order of such things which are simultaneous.
