In Metaphysics M.2, 1077a9-14, Aristotle appears to argue against the existence of Platonic Forms on the basis of there being certain universal mathematical proofs which are about things that are ‘beyond’ the ordinary objects of mathematics and that cannot be identified with any of these. It is a very effective argument against Platonism, because it provides a counter-example to the core Platonic idea that there are Forms in order to serve as the object of scientific knowledge: the universal of which (...) theorems of universal mathematics are proven in Greek mathematics is neither Quantity in general nor any of the specific quantities, but Quantity-of-type-x. This universal cannot be a Platonic Form, for it is dependent on the types of quantity over which the variable ranges. Since for both Plato and Aristotle the object of scientific knowledge is that F which explains why G holds, as shown in a ‘direct’ proof about an arbitrary F (they merely disagree about the ontological status of this arbitrary F, whether a Form or a particular used in so far as it is F), Plato cannot maintain that Forms must be there as objects of scientific knowledge - unless the mathematics is changed.

In this paper we carefully study the problem of liberty as it applies to school choice, and whether there ought to be restricted liberty in the case of homeschooling. We examine three prominent concerns that might be brought against homeschooling, viz., that it aggravates social inequality, worsens societal conflict and works against the best interests of children. To examine the tensions that occur between parental liberty, children's interests, and state oversight, we consider the case of homeschooling in the Dutch context.

This transcription of a keynote for the Speculative Art Histories conference in May 2013 is a mixture of the main argument of The Sympathy of Things and some new insights. The text might be helpful for those who have not read the Sympathy book, which has been sold out for a number of years. This essay will appear as a chapter in Sjoerd van Tuinen's Speculative Art Histories, to be published with Edinburgh University Press in 2017.
