Marketless trading in Hammurabi’s time: A re-appraisal

In this article I revisit Karl Polanyi’s writings on ancient Mesopotamia. I begin by situating them in the context of his general approach to trade, markets and money in the ancient world. Next, I reconstruct his major theses on Mesopotamia, drawing upon his published works as well as unpublished documents in the Karl Polanyi and Michael Polanyi archives. Finally, I provide a critical assessment of the merits and demerits of his contribution, with reference to Assyriological research published in the decades that have elapsed since his death in 1964

Anselm’s Metaphysics of Nonbeing

In his eleventh century dialogue De Casu Diaboli, Anselm seeks to avoid the problem of evil for theodicy and explain the fall of Satan as attributable to Satan’s own self-creating wrongful will. It is something, as such, for which God as Satan’s divine Creator cannot be held causally or morally responsible. The distinctions on which Anselm relies presuppose an interesting metaphysics of nonbeing, and of the nonbeing of evil in particular as a privation of good, worthy of critical philosophical investigation in its own right. Anselm’s concept of nonbeing does not resolve the philosophical problem of evil implied by Satan’s fall from grace, but is shown perhaps more unexpectedly to enable Anselm’s proof for the inconceivable nonexistence of God as the greatest conceivable intended object of thought to avoid Kant’s Critique of Pure Reason objection to the general category of ”ontological’ arguments

"Like wildfire" The east German rising of June 1953

Before the archives of the East German state were opened in the early 1990s the rising of June 1953 had already been well documented, largely on the basis of eyewitness reports and the East German press. It was thought that up to 372,000 workers took strike action, and that many of these participated, along with several hundred thousand others, in marches, rallies, occupations and other forms of direct action. Much was known about the sequence of events, the demands voiced, and about some of the individuals involved. As the first of several mass uprisings against Stalinist regimes, but doubtless also due to the breathtaking speed with which a strike at a Berlin building site spread to other workplaces and thence to streets and public squares nationwide, it attracted a good deal of attention from historians. An abundance of books, articles and pamphlets followed

Collection analysis for Horn clause programs

We consider approximating data structures with collections of the items that they contain. For examples, lists, binary trees, tuples, etc, can be approximated by sets or multisets of the items within them. Such approximations can be used to provide partial correctness properties of logic programs. For example, one might wish to specify than whenever the atom $sort(t,s)$ is proved then the two lists $t$ and $s$ contain the same multiset of items (that is, $s$ is a permutation of $t$). If sorting removes duplicates, then one would like to infer that the sets of items underlying $t$ and $s$ are the same. Such results could be useful to have if they can be determined statically and automatically. We present a scheme by which such collection analysis can be structured and automated. Central to this scheme is the use of linear logic as a omputational logic underlying the logic of Horn clauses
