 However, suppose that, like Aristotle, you take ordinary language accurately to reflect the structure of the world. Then you could recognize systematic everyday uses of ‘up’ and ‘down’ that require some privileged standards – uses that treat things closer to a point at the center of the Earth as more ‘down’ and motions towards that point as ‘downwards’. Of course we would likely explain this usage in terms of the fact that we and our language evolved in a very noticeable gravitational field directed towards the center of the Earth; but for Aristotle, as we shall see, this usage helped identify an important structural feature of the universe, which itself was required for the explanation of weight. Now a further question arises: how should a structure, such as a preferred point in the universe, which privileges certain motions, be understood? What makes that point privileged? One might expect that Aristotle simply identified it with the center of the Earth, and so relative to that particular body; however, we shall soon see that he did not adopt that tacit convention as fundamental. So the question arises of whether the preferred point is somewhere picked out in some other way by the bodies in the universe – the center of the heavens perhaps? Or is it picked out quite independently of the arrangements of matter?
