There is an ongoing debate over cosmological fine-tuning between those holding that design is the best explanation and those who favor a multiverse. A small group of critics has recently challenged both sides, charging that their probabilistic intuitions are unfounded. If the critics are correct, then a growing literature in both philosophy and physics lacks a mathematical foundation. In this paper, I show that just such a foundation exists. Cosmologists are now providing the kinds of measure-theoretic arguments needed to make the case for fine-tuning. Introduction Probability and infinite sets 2.1 No probability function 2.2 Arbitrary and wrong probability functions The measure of the universe The coarse-tuning objection Arbitrariness and error Conclusion.

In his recent anthology, Intelligent Design Creationism and Its Critics, Robert Pennock continues his attack on what he considers to be the pseudoscience of Intelligent Design Theory. In this critical review, I discuss the main issues in the debate. Although the rhetoric is often heavy and the articles are intentionally stacked against Intelligent Design, there are many interesting topics in the philosophy of science to be found. I conclude that, contra Pennock, there is nothing intrinsically unscientific about Intelligent Design. At this stage, however, it remains more of a provocative idea than a research program. Whether design theorists can bridge this gap is still very much in question. In any case, the debate serves as a modern case study for such classic problems as the nature of scientific explanations, theory change, the demarcation problem, and the role of metaphysical assumptions in the development of science.

Scientific knowledge is often categorized as experimental or theoretical. There is, however, a third layer where philosophy of science and science proper overlap, the realm of metatheoretic shaping principles. For example, we assume that the causal regularities observed today will also hold tomorrow. Researchers are thereby relying on two metaphysical doctrines: the uniformity of nature and mechanistic causation. There are also the “explanatory virtues” of simplicity, testability, internal and external coherence, fruitfulness, and wide scope. My first goal is to categorize these principles and show how they’ve operated in the history of science. Particular attention will be paid to their suspension and rejection, even of widely held principles. My second goal is to consider how certain shaping principles impinge on open theology. Of particular interest will be naturalism (both metaphysical and methodological), reductionism, and realism. Surprisingly, differences within the open theology camp are more relevant to these issues than open theism itself.
