Experimental research is commonly held up as the paradigm of "good" science. Although experiment plays many roles in science, its classical role is testing hypotheses in controlled laboratory settings. Historical science is sometimes held to be inferior on the grounds that its hypothesis cannot be tested by controlled laboratory experiments. Using contemporary examples from diverse scientific disciplines, this paper explores differences in practice between historical and experimental research vis-à-vis the testing of hypotheses. It rejects the claim that historical research is (...) epistemically inferior. For as I argue, scientists engage in two very different patterns of evidential reasoning and, although there is overlap, one pattern predominates in historical research and the other pattern predominates in classical experimental research. I show that these different patterns of reasoning are grounded in an objective and remarkably pervasive time asymmetry of nature. (shrink)

A policy turn in environmental philosophy means a shift from philosophers writing philosophy essays for other philosophers to doing interdisciplinary research and working on projects with public agencies, policy makers, and the private sector. Despite some steps in this direction, a policy turn remains largely unrealized within the community of environmental philosophers. Completing this shift can contribute to better decision making, help discover new areas for philosophic investigation at the intersection of philosophy and policy, and identify new employment prospects for (...) philosophy graduates.

New discoveries about materials and solar energy raise the possibility of a long-tenn shift of mining, refining, and manufacturing from Earth’s surface to locations outside Earth’s ecosphere, allowing Earth to begin to relax back toward its natural state. A little-discussed ambivalence toward the potential of space exploration exists among environmentalists. One camp sees it as a human adventure that may allow a bold initiative to improve Earth; another camp shies away from “heavy technology” and thus distrusts efforts as massive as (...) space exploration or utilization. Due to impending resource depletion on Earth, we may have only until the mid-twenty-first century to pursue the promising potential of space exploration to alleviate environmental problems of Earth. Subsequently, there may be too litde industlial base to support vigorous exploration and exploitation of resources in space. (shrink)

ABSTRACT After a brief review of environmental ethics this paper examines how terrestrial environmental values can be developed into policies to protect extraterrestrial environments. Shallow environmentalism, deep environmentalism and the libertarian extension of rights are compared and then applied to the environmental protection of extraterrestrial bodies. Some scientific background is given. The planet Mars is used as a test case from which an ethical argument emerges for the protection of environments beyond Earth. The argument is based on the necessity to (...) recognise the intrinsic value of all living species and natural environments. At present, the treatment of extraterrestrial environments by makers of space policy is ethically undernourished. This paper explains why such an attitude endangers those environments and calls for the policy‐makers to incorporate non‐anthropocentric ethics into extraterrestrial environmental policy. (shrink)

By attempting to divorce attributions of value from judgments of the interest of the attributor, developing the concept ofa locus of value, exploring the interconnections between the goods of individuals and the goods of populations and species, and suggesting the reasonableness ofthe attributions of rights to certain sorts of individuals, I try to indicate the degree to which an environmental ethic can be atomisticwithout being anthropocentric.

Subtitled "Studies in Ethical Analysis," this collection of eleven essays, most of which have previously appeared in journals, deals with a number of problems central to modern ethical theory: the emotive interpretation of ethical language, persuasive definitions and their role in ethical reasoning, the cognitive versus emotive conceptions of ethics: many of these problems were first raised and examined by Stevenson in his earlier book Ethics and Language. Other essays are of a less retrospective nature: studies on Moore and Dewey, (...) naturalism and relativism in ethics, and a general discussion of the relations of linguistic analysis to philosophy as a whole. Stevenson is mainly concerned with analytical, as opposed to descriptive, ethics; and he completely avoids the topics of normative ethics except for a brief survey. The approach to ethics is therefore restricted, but there is enough here to interest the philosopher whose main area lies outside of ethics; although it presupposes no acquaintance with the author's previous work, some of the questions on emotivism and persuasive language are more motivated when seen in the context of that work.—P.
