Culture, Judgment, Integration of Attention and Argumentation

Some exchanges of reasons are agonistic. Others work mutually, as in planning and adjusting divergent understanding. Mutual argumentation subconsciously yields judgment that integrates and clarifies a common vision coordinating interrelated lives. It harmonizes agents sharing a space of action and understanding. Pierre Bourdieu held that such thought generates and expresses culture, patterning a logic that reflexively constrains itself. This discussion examines Bourdieu’s views as an analysis of mutual argumentation

Community, argumentation, and the legitimacy of reasons for action

Communities gather persons sharing saliencies, the meaning of events, and accountability based in shared values and practices. These shared features ensure community wide legitimacy for moral agents and their reasons for acting. But they also might ensure personal reasons for action are not universally legitimate. This discussion considers Hannah Arendt’s and an alternative view of judgment seeking an ac-count of community-limited legitimacy for reasons in both moral and closely related political thought

Wide reflective equilibrium and conductive argument

In this paper I compare and contrast Rawls’s notion of reflective equilibrium with Wellman‘s notion of conductive argument. In the course of so doing I will address two key questions: (1) Are conduc-tive argument and reflective equilibrium best understood as modes of reasoning or types of argument? and (2) What relationship (logical, pragmatic, etc.), if any, is there between them

Geochemical considerations for Hot, Dry Rock Systems

Circulating systems intended to model the P-T conditions found in the natural HDR (Hot Dry Rock) geothermal system at Los Alamos have been built. Experiments with these systems have determined the following parameters for the ''down hole'' reservoir: sample weight loss, circulating solution composition, textural changes in the rock, mineral loss from the rock and effects of chemical additives on rock erosion. The analyses of solutions generated from rock-water interactions in the experimental systems show the extremely dilute nature of the working fluid. These solutions are not brines. Silica scaling in the surface heat exchanger was found to account for the difference between loss of sample rate and analyzed silica in the solution. The weight loss data indicate that there was continuous transport of silica from the ''down hole'' rock to the heat exchanger. Experiments contrasting felsic and mafic rocks in the HDR concept indicate that a reservoir consisting of glass bearing basaltic rock would tend to produce greater scaling problems than systems emplaced in granite. Experimental results suggest that Na{sub 2}CO{sub 3} solutions may provide a means of increasing permeability and thereby increasing the effective heat transfer area of the reservoir. A brief description is given of a small test loop for simulating the flow of a geothermal solution through a heat exchanger. This loop, which is being built, will be used to study the coagulation and precipitation of silica under conditions similar to those expected in the field
