What is the role of poetry in bringing about change? This book explores that question in the writings of Percy Bysshe Shelley, examining his fascination with the role of contingency in physical and historical processes. In considering the long-standing debate over Shelley's philosophical stance, Hugh Roberts turns to the poet's reading of Lucretius to show how Shelley developed an alternative approach to the issues of history, change, time, and process—one that incorporates the most compelling features of skepticism and idealism. (...) He sheds new light on the importance of _De rerum natura _to Shelley's thought, and through extended readings of _The Revolt of Islam_ and _The Triumph of Life_ he shows the poet struggling with the intellectual limitations of Romanticism and the Enlightenment and moving beyond them. Roberts then deploys some of the key concepts from the new science of chaos theory to illuminate the wider implications of Shelley's approach. He shows how with the help of this new paradigm much that has seemed baffling about the poet falls into place—most notably a new understanding of political process that allows us to better comprehend Shelley's claim that "poets are the unacknowledged legislators of the world." Readings of a number of Shelley's poems and prose works demonstrate the wide-ranging implications of this approach for our understanding of his entire oeuvre. _Shelley and the Chaos of History_ presents a Shelley whose investigations into the nature of history and the role of poetry lead us beyond contemporary deconstructionist-historicist debates. It shows that the complexity of Shelley's engagement with the major philosophical issues of his time has been greatly underestimated. (shrink)

Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. . Picture changes (...) during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

The rapid commercialization of applied genetics in the mtd-1970s, accompanied by a sudden rise in academic-corporate partnerships, raised questions about the impacts these linkages have had on the social and professional norms of scientists. The extent and pattern of faculty tnvolvement in commercialization of biological research is largely an unexplored area. This article provcdes a quantitative assessment of the linkages between biology faculty in American uncverscties and the newly formed biotechnology industry. The results of thes study, covering the period 1985-88, (...) show that academic scientists responded en masse to participating in the commercialization of genetecs research by estabhshmg formal associations with many of the new biotechnology compances. A data base consisting of 889 U.S. and Canadian biotechnology companies and 832 sccentcsts who had formal ties to them was developed over a four-year period. The patterns of academic-corporate Icnkages are revealed by institution. Three universities with the most commercially active faculty are Harvard, Stanford, and MIT. Of the 359 bcomedeca! scientists and geneteccsts who were members of the Nateonal Academy of Sceences, at minimum, 37% had formal ties with the biotechnology industry. (shrink)

Discussions of critical thinking across the curriculum typically make and explain points and distinctions that bear on one or a few standard issues. In this article Robert Ennis takes a different approach, starting with a fairly comprehensive concrete proposal for a four-year higher-education curriculum incorporating critical-thinking at hypothetical Wisdom University. Aspects of the Program include a one-year critical thinking freshman course with practical everyday-life and academic critical thinking goals; extensive infusion of critical thinking in other courses; a senior (...) project; attention to both critical thinking dispositions and skills; a glossary of critical thinking terms; emphasis on teaching ; communication at all levels; and last, but definitely not least, assessment. Advantages and disadvantages will be noted. Subsequently, Ennis takes and defends a position on each of several relevant controversial issues, including: 1) having a separate critical thinking course, or embedding critical thinking in existing subject matter courses, or doing both ; 2) the meaning of “critical thinking”; 3) the importance of teaching critical thinking because of its role in our everyday vocational, civic, and personal lives, as well as in our academic experiences; 4) the degree of subject-specificity of critical thinking; 5) the importance of making critical thinking principles explicit; and 6) the possible threat to subject matter coverage from the addition of critical thinking to the curriculum.

Defining qualified reasoning as reasoning containing such loose qualifying words as 'probably,' 'usually,' 'probable, 'likely,' 'ceteris paribus,' and 'primafacie, Ennis argues that typical cases of qualified reasoning, though they might be good arguments, are deductively invalid, implying that such arguments fail soundness standards. He considers and rejects several possible alternative ways of viewing such cases, ending with a proposal for applying qualified soundness standards, which requires employment of sufficient background knowledge, sensitivity, experience and understanding of the situation. All of (...) this takes place as part of the process, introduced elsewhere, of successively applying different legitimate sets of standards until one is found that is satisfied, or none is found, the latter calling for rejection of the argument, the former calling for its acceptance.

Assuming that critical thinking dispositions are at least as important as critical thinking abilities, Ennis examines the concept of critical thinking disposition and suggests some criteria for judging sets of them. He considers a leading approach to their analysis and offers as an alternative a simpler set, including the disposition to seek alternatives and be open to them. After examining some gender-bias and subject-specificity challenges to promoting critical thinking dispositions, he notes some difficulties involved in assessing critical thinking dispositions, (...) and suggests an exploratory attempt to assess them.

This essay offers a comprehensive vision for a higher education program incorporating critical thinking across the curriculum at hypothetical Alpha College, employing a rigorous detailed conception of critical thinking called “The Alpha Conception of Critical Thinking”. The program starts with a 1-year, required, freshman course, two-thirds of which focuses on a set of general critical thinking dispositions and abilities. The final third uses subject-matter issues to reinforce general critical thinking dispositions and abilities, teach samples of subject matter, and introduce subject-specific (...) critical thinking. Subject-matter departmental and other units will make long-range plans for incorporating critical thinking in varying amounts in subject-matter courses, culminating in a written Senior Thesis/Project involving investigating, taking, and defending a position, which reinforce critical thinking abilities and dispositions and increase subject-matter knowledge. Teaching approaches used in the program are involving and based on the principle, “We learn what we use.” Both summative and formative assessment are employed as appropriate. Coordination and support are extensive. Objections and concerns are discussed, and alternatives, including possible transitions, are considered. An extended review of research supports moving toward CTAC. (shrink)

A popular three-stage argument appraisal strategy calls for (1) identifying the parts of the argument, (2) classifYing the argument as deductive, inductive, or some other type, and (3) appraising the argument using the standards appropriate for the type. This strategy fails for a number of reasons. I propose a comprehensive alternative approach that distinguishes between inductive, deductive, and other standards; calls for the successive application of standards combined with assumption-ascription, according to policies that depend for their selection on the goals (...) of the appraiser; and provides for qualified reasoning.

This paper attempts to respond to the critique that critical thinking courses may reflect a cultural bias. After elaborating a list of constitutive dispositions and abilities taught in the critical thinking curriculum (e.g. a direct approach to writing and speaking, care about the dignity and worth of every person, positions towards deductive reasoning, shared decision-making, etc.), the author considers arguments for why several of these might reflect Western, non-universal values. In each case, the author argues for the conclusion that these (...) values, though they could be applied in ways that reflect a cultural bias, are not inherently biased. Next, the author offers an outline of a more systematic examination of cultural bias. After reiterating the “tentative conclusion” that critical thinking is not culturally biased, the paper concludes by considering the various ways in which critical thinking might be promoted so as to ensure its sensitivity to cultural differences.

Necessary-condition analyses of singular causal claims are particularly vulnerable to cases of linked overdetermination, so named because the nonoperation of the back-up factor (in fail-safe cases) or the preempted factor (in preemptive cases) is linked to the operation of the actual cause. As an example J. L. Mackie's analysis is here challenged with a simple switch-light case. Three replies are considered, a facts-vs.-events reply, a different-effect reply, and an in-the-circumstances reply. All are found deficient.

To claim that x was the cause of y is 1) to assume that x was one of a number of things, each of which together with the others was sufficient to have brought about y, and 2) to deem x responsible for the occurrence of y. A best-explanation argument, including application to cases, is offered in defense of this analysis, which holds that claiming that something is the cause is, in part, a speech act that reflects the cause selector’s (...) values or perspectives. No proposed alternative explanation accounts for all the cases with which I am familiar, but this analysis does account for them. Thus the analysis and the defense of sole singular causal claims call for more than empirical evidence, though of course evidence is very important. (shrink)

Even given agreement on the totality of conditions that brought about an effect, there often is disagreement about the cause of the effect, for example, the disagreement about the cause of the Gulf oil spill. Different conditions’ being deemed responsible accounts for such disagreements. The defense of the act of deeming a condition responsible often depends on showing that the condition was the appropriate target of interference in order to have avoided the effect.

SummaryIn this essay I offer a set of characteristic scientific activities, accompanied by principles to be used as guides in performing these activities, and dispositions that are desirable for the person performing these activities to have. This set is intended to provide a rough and ready elaboration of scientific thinking as a goal for our schools and colleges.Although they are here labeled scientific, they are intended to apply to other activities than doing what is standardly called science. This wider application (...) is part of the justification for offering science in our schools and colleges. We want people to think scientifically about many other aspects of their lives, as well as about science content.There is no suggestion that science content is not important, nor that scientific thinking should be taught apart from science content. In fact I think that a very good way to teach scientific thinking is by infusing such instruction in the instruction of science content. See Swartz for a discussion of infusion, and Ennis, for treatments of the subject‐specificity issue that is generally raised when thinking and content are discussed.This essay contains one brief case study that exemplifies most of the activities, principles, and dispositions suggested as goals for the schools. I realize that the validity and comprehensiveness of these goals has not been here demonstrated. The scientists, science educators, philosophers of science, and critical thinking specialists to whom1 have shown them are in general agreement about them, but the ultimate test will be in whether the goals are widely adopted and successfully serve as guidance in the promotion of scientific thinking.I hope that this elaboration of scientific thinking and its formulation in terms of a suggested set of goals are “dear and precise as is needed in the situation”.

Does the content of a physically dangerous job affect the moral permissibility of hiring for that job? To what extent may employers consider costs in choosing workplace safety measures? Drawing on Kantian ethical theory, this article defends two strong ethical standards of workplace safety. First, the content of a hazardous job does indeed affect the moral permissibility of offering it. Unless employees need hazard pay to meet basic needs, it is permissible to offer a dangerous job only if prospective employees (...) have a reason other than hazard pay to choose this job instead of safer alternatives. Second, employers typically cannot justify omitting expensive safety measures by paying employees more, even if employees prefer higher pay to greater safety. Employers offering dangerous jobs must meet these two standards to avoid treating their employees merely as means. (shrink)

The Spellings Commission recommends widespread critical-thinking testing to help determine the “value added” by higher education institutions—with the data banked and made available (“transparent”) in order to enable parents, students, and policy makers to compare institutions and hold them accountable. Because of the likely and desirable promotion of critical thinking that would result from the Commission’s program, I recommend cooperation by critical-thinking faculty and administrators, but only if there is much less comparability and considerably deeper transparency of the tests and (...) their justification than the Commission recommends, and only if vigilance in handling the many problems and dangers elaborated herein is successful.
