Oversimplifying the Supreme Court

I cannot tell you what a pleasure it is to be at the Supreme Court Historical Society. Of course, the Supreme Court is fortunate to have a Chief Justice who is also Chief Historian. I have read each of Chief Justice Rehnquist's books on the Court, and they are engagingly written narratives filled with a love and knowledge of this institution. The Chief Justice is steeped in the folklore of this remarkable Court as few have ever been. This is just one reason those of us throughout the federal judiciary admire and love the Chief. He has shown kindness to me ever since I was a young law clerk for Justice Lewis Powell. I don't know if it's appropriate or not to dedicate a speech, but I am going to do so anyway. This speech is for him.

“Boundless Compassion”: The Contemporary Relevance of Schopenhauer's Ethics

Schopenhauer had important things to say about ethics in both normative and meta-ethical senses, but his impact on the evolution of moral theory has been minimized by the unfortunate neglect of his philosophy in general. A contemporary assessment of his ethical views reveals that they are both imaginative and interesting, not least because they challenge assumptions held by more canonical figures in the history of philosophy, both before and after his time. Since the roots of ethics are currently being vigorously re-examined, it is regrettable that Schopenhauer's ideas have been omitted from mainstream discussion in the field. I attempt to remedy this lack by investigating how his ethics of compassion contributes to the following areas: reconciling ethics with strict determinism; naturalizing ethics; developing the philosophy of education; seeking inner peace and world peace; re-visioning our relationship with non-human animals and the environment. As this list indicates, Schopenhauer's moral theory has relevance for a much wider audience, beyond the limited sphere of professional philosophy. And because the world is in dire need of moral rejuvenation, any inspiration provided by a major thinker such as Schopenhauer should be heartily welcomed. While certain internal problems are posed by his metaphysical and epistemological doctrines, we can see past these in order to appropriate the living insights still to be found in Schopenhauer's ethical thought.     

The Materiality of Social Power: The Artifact-Acquisition Perspective

This paper explores the materiality of social power relationally through study of social interactions with artifacts. Specifically, it is argued that acquisition of an artifact instantiates social power by imposing interactions on groups taking part in that artifact's life-history activities. We introduce the “performance-preference matrix,” an analytic tool for systematically studying the effects of such acquisition events on activity groups. The use of the performance-preference matrix is illustrated through an example: the acquisition of electric-arc lights for lighthouses in the 19th century. Suggestions are offered for analyzing culture-contact situations and for handling singularized artifacts such as heirlooms and monuments.

Behavioral Ecology and Archaeology

Behavioral ecology is the study of adaptive behavior in relation to social and environmental circumstances. Analysts working from this perspective hold that the reproductive strategies and decision-making capacities of all living organisms—including humans—are shaped by natural selection. Archaeologists have been using this proposition in the study of past human behavior for more than 30 years. Significant insights on variation in prehistoric human subsistence, life history, social organization, and their respective fossil and archaeological consequences have been among the more important results.     

New World States and Empires: Politics, Religion, and Urbanism

The past decade has seen a veritable explosion in archaeological research on complex societies in Latin America. In 1993, Smith published an overview of research to that date; this article is one of two bringing that summary up to the present. Our first article, New World states and empires: Economic and social organization (Smith and Schreiber, 2005), dealt with issues regarding economic and social organization. The present article tackles political organization and dynamics, religion, urbanism, and settlement patterns. We also review recent research in the context of various theoretical perspectives, some traditional, some more contemporary, including approaches to history and process, cultural evolution, agency-based models, linguistic prehistory, migration theory, and the relationship between environmental change and cultural events. Our discussion blends empirical findings, methodological advances, and theoretical perspectives.     

Monitoring fluid chemistry in iron oxide–copper–gold‐related metasomatic processes,eastern Mt Isa Block,Australia

Most researchers in the Proterozoic eastern Mt Isa Block, NW Queensland, Australia, favour magmatic fluid and salt sources for sodic‐(calcic) alteration and iron oxide–copper–gold mineralization. Here we compare spatial, mineralogic and stable isotope data from regional alteration assemblages with magmatic and magmatic‐hydrothermal interface rocks in order to track chemical and isotopic variations in fluid composition away from inferred fluid sources. Tightly clustered δ¹⁸O values for magnetite, quartz, feldspar and actinolite for igneous‐hosted samples reflect high temperature equilibration in the magmatic‐hydrothermal environment. In contrast, these minerals record predominantly higher δ¹⁸O values in regional alteration and Cu–Au mineralization. This dichotomy reflects partial equilibration with isotopically heavier wallrocks and slightly lower temperatures. Increases in Si concentrations of metasomatic amphiboles relative to igneous amphiboles in part reflect cooling of metasomatic fluids away from igneous rocks. Variations in X_Mg for metasomatic amphiboles indicate local wallrock controls on amphibole chemistry, while variations in X_Cl/X_OH ratios for amphiboles (at constant X_Mg) indicate variable aH₂O/aHCl ratios for metasomatic fluids. Biotite geochemistry also reflects cooling and both increases and decreases in aH₂O/aHCl for fluids away from plutonic rocks. Decreased aH₂O/aHCl ratios for metasomatic fluids reflect in part scavenging of chlorine out of meta‐evaporite sequences, although this process requires already saline fluids. Local increases in aH₂O/aHCl ratios, as well as local decreases in δ¹⁸O values for some minerals (most notably haematite and epithermal‐textured quartz), may indicate ingress of low salinity, low δ¹⁸O fluids of possible meteoric origin late in the hydrothermal history of the region. Taken together, our observations are most consistent with predominantly magmatic sources for metasomatic fluids in the eastern Mt Isa Block, but record chemical and isotopic variations along fluid flow paths that may be important in explaining some of the diversity in alteration and mineralization styles in the district.     

Fracture sealing and fluid overpressures in limestones of the Jabal Akhdar dome,Oman mountains

Fractures are important conduits for fluid flow in the Earth's crust. To better understand the spatial and temporal relations among fracturing, fracture sealing, and fluid flow, we have studied fractures, faults, and veins in a large dome (Jabal Akhdar) in the Oman mountains. Our work combines the results of meso‐ and microstructural analyses and stable isotope analyses. Seven generations of fractures and veins have been identified in the carbonate‐dominated dome. The earliest generations of veins developed during extension and subsidence of the Mesozoic basin. These veins formed in the inclined segments of bedding‐parallel stylolites and in extensional fractures that are perpendicular to bedding (#1 and #2, respectively). These extension‐related veins are truncated by bedding‐parallel veins (#4) that formed during top‐to‐north bedding‐parallel shear of both the northern and southern limbs of the dome. These veins are consistent with a change in stress regime and may be related to an earlier generation of strongly deformed pinch‐and‐swell veins (#3) that are exposed locally on the southern limb of the dome. Normal faults contain a set of en‐echelon tension gashes (#5) and veins emplaced in dilational jogs along the fault planes (#6). In the northern part of the dome, veins (#7) associated with thrusts post‐date the normal faults. Samples of veins and their host rocks were analyzed to provide information on fluid‐rock interaction in the dome and the scale(s) of fluid movement. Oxygen isotope values range from +16.2 to +29.3‰; carbon isotope values range from 0 to +3.6‰. The results of the structural and isotopic analyses are consistent with the early veins (#2–#5) having precipitated from overpressured fluid in a isotopically rock‐buffered system. During normal faulting (#5 and #6), a more open system allowed external fluid to infiltrate the dome at drained conditions and precipitate the youngest sets of veins (#6 and #7).
