The Political Question Doctrines

Two radical neuron doctrines

Two radical neuron doctrines must be distinguished--strong and weak. G&S direct much of their attack at the former--but the Churchlands only hold the latter. The weak radical neuron doctrine remains a serious possibility. G&S describe the radical neuron doctrine in a number of slightly different ways, and we think this hides an important distinction. On the one hand, the radical neuron doctrine...

Challenging the doctrines of JPEG steganography

The design of both steganography and steganalysis methods for digital images heavily relies on empirically justified principles. In steganography, the domain in which the embedding changes are executed is usually the preferred domain in which to measure the statistical impact of embedding (to construct the distortion function). Another principle almost exclusively used in steganalysis states th...

Robust Political Economy and thE QuEstion of motivations

Boettke, Leeson and Subrick (Boettke and Leeson 2004; Leeson and Subrick 2006) describe institutional robustness as the ability of a given system of social organization to stand up to the test of the so-called “hard cases,” i.e., hypothetical scenarios under which the ideal assumptions concerning, e.g., information and motivation possessed by the members of a given society are relaxed. In this ...

Detecting Doctrines: The Case Method and the Detective Story

A Co-free Construction for Elementary Doctrines

We provide a construction which co-freely adds elementary structure to a primary doctrine in the sense of Lawvere. We show that the construction preserves all the first order logical structures that the starting doctrine may have. Moreover it forces the Principle of Propositional Extensionality when applied to tripos.
