Genealogical narrative and self-knowledge in Rousseau's Discourse on the Origin and the Foundations of Inequality among Men

SUMMARY

Why did Rousseau cast the substance of the Second Discourse in the form of a genealogy? In this essay the author attempts to work out the relation between the literary form (genealogical narrative, as the author calls it) of the Discourse's two main parts and the content. A key thesis of Rousseau's text concerns our lack of self-knowledge, indeed, our ignorance of our ignorance. The author argues that in a number of ways genealogical narrative is meant to respond to that lack. In the course of his discussion he comments on Rousseau's puzzling remarks in the Second Discourse about his expository method. Further, given the thesis that we lack self-knowledge, Rousseau owes us an account of his genesis as self-knowing genealogist. He attempts to do so in part through his narrative of the ‘illumination of Vincennes’. The author examines that narrative as well, reading it and the Discourse in light of each other. Can Rousseau resolve the problems of self-reference that the philosophical use of genealogy often leads to? The article discusses this complex metaphilosophical problem, along with views about the value of genealogical accounts, in light of recent work by Robert Guay, John Kekes, Alasdair MacIntyre, and Frederick Neuhouser, among others.     

Non‐Destructive Survey of Early Roman Copper‐Alloy Brooches using Portable X‐ray Fluorescence Spectrometry

This paper argues that portable X‐ray fluorescence spectrometry (pXRF) is a suitable elemental measurement technique to study the production of copper‐alloy artefacts. However, rather than try to imitate the accuracy and precision of laboratory techniques, it is more beneficial to deploy it in a survey role, one that attempts to model chronological and geographical changes within large quantities of artefacts. To achieve this, it was investigated to what extent corrosion and the issues surrounding surface measurements affect the potential of this type of research. Analyses on early Roman period brooches gathered in the Nijmegen region of the Netherlands were subsequently compared with published data.     

A compositional perspective on the origins of the “Nasca cult” at Cahuachi

We provide a compositional perspective on the origins of the Cahuachi cult in Nasca, south coast of Peru. Instrumental Neutron Activation Analysis of ceramics from the Formative site of La Puntilla demonstrate that a small group of pottery known as Nasca 1 blackwares are compositionally consistent with Early Nasca polychromes originating at Cahuachi. These data suggest that the patterns of pilgrimage and group ceremonies exhibited at Cahuachi during Early Nasca began at least in the proto-Nasca phase of Nasca 1 during the Formative. We use these data to further document the Paracas to Nasca transition, a complex and dynamic period in south coastal prehistory.     

The discovery of motor cortex and its background

In 1870 Gustav Fritsch and Edvard Hitzig showed that electrical stimulation of the cerebral cortex of a dog produced movements. This was a crucial event in the development of modern neuroscience because it was the first good experimental evidence for a) cerebral cortex involvement in motor function, b) the electrical excitability of the cortex, c) topographic representation in the brain, and d) localization of function in different regions of the cerebral cortex. This paper discusses their experiment and some developments in the previous two centuries that led to it including the ideas of Thomas Willis and Emanuel Swedenborg, the widespread interest in electricity and the localizations of function of Franz Joseph Gall, John Hughlings Jackson, and Paul Broca. We also consider the subsequent study of the motor cortex by David Ferrier and others.
