Creationists have acquired a more sophisticated intellectual arsenal. This book reveals the insubstantiality of their arguments. Creationism is no longer the simple notion it once was taken to be. Its new advocates have become more sophisticated in how they present their views, speaking of "intelligent design" rather than "creation science" and aiming their arguments against the naturalistic philosophical method that underlies science, proposing to replace it with a "theistic science." The creationism controversy is not just about the status of Darwinian (...) evolution—it is a clash of religious and philosophical worldviews, for a common underlying fear among Creationists is that evolution undermines both the basis of morality as they understand it and the possibility of purpose in life. In Tower of Babel, philosopher Robert T. Pennock compares the views of the new creationists with those of the old and reveals the insubstantiality of their arguments. One of Pennock's major innovations is to turn from biological evolution to the less charged subject of linguistic evolution, which has strong theoretical parallels with biological evolution, both in content and in the sort of evidence scientists use to draw conclusions about origins. Of course, an evolutionary view of language does conflict with the Bible, which says that God created the variety of languages at one time as punishment for the Tower of Babel. Several chapters deal with the work of Phillip Johnson, a highly influential leader of the new Creationists. Against his and other views, Pennock explains how science uses naturalism and discusses the relationship between factual and moral issues in the creationism-evolution controversy. The book also includes a discussion of Darwin's own shift from creationist to evolutionist and an extended argument for keeping private religious beliefs separate from public scientific knowledge.

In the 2005 Kitzmiller v Dover Area School Board case, a federal district court ruled that Intelligent Design creationism was not science, but a disguised religious view and that teaching it in public schools is unconstitutional. But creationists contend that it is illegitimate to distinguish science and religion, citing philosophers Quinn and especially Laudan, who had criticized a similar ruling in the 1981 McLean v. Arkansas creation-science case on the grounds that no necessary and sufficient demarcation criterion was possible and (...) that demarcation was a dead pseudo-problem. This article discusses problems with those conclusions and their application to the quite different reasoning between these two cases. Laudan focused too narrowly on the problem of demarcation as Popper defined it. Distinguishing science from religion was and remains an important conceptual issue with significant practical import, and philosophers who say there is no difference have lost touch with reality in a profound and perverse way. The Kitzmiller case did not rely on a strict demarcation criterion, but appealed only to a “ballpark” demarcation that identifies methodological naturalism (MN) as a “ground rule” of science. MN is shown to be a distinguishing feature of science both in explicit statements from scientific organizations and in actual practice. There is good reason to think that MN is shared as a tacit assumption among philosophers who emphasize other demarcation criteria and even by Laudan himself. (shrink)

Responsible conduct of research training typically includes only a subset of the issues that ought to be included in science ethics and sometimes makes ethics appear to be a set of externally imposed rules rather than something intrinsic to scientific practice. A new approach to science ethics training based upon Pennock’s notion of the scientific virtues may help avoid such problems. This paper motivates and describes three implementations—theory-centered, exemplar-centered, and concept-centered—that we have developed in courses and workshops to introduce students (...) to this scientific virtue-based approach.

Phillip Johnson claims that Creationism is a better explanation of the existence and characteristics of biological species than is evolutionary theory. He argues that the only reason biologists do not recognize that Creationist's negative arguments against Darwinism have proven this is that they are wedded to a biased ideological philosophy —Naturalism — which dogmatically denies the possibility of an intervening creative god. However,Johnson fails to distinguish Ontological Naturalism from Methodological Naturalism. Science makes use of the latter and I show how (...) it is not dogmatic but follows from sound requirements for empirical evidential testing. Furthermore, Johnson has no serious alternative type of positive evidence to offer for Creationism, and purely negative argumentation, despite his attempt to legitimate it, will not suffice.

That Intelligent Design Creationism rejects the methodological naturalism of modern science in favor of a premodern supernaturalist worldview is well documented and by now well known. An irony that has not been sufficiently appreciated, however, is the way that ID Creationists try to advance their premodern view by adopting (if only tactically) a radical postmodern perspective. This paper will reveal the deep threads of postmodernism that run through the ID Creationist movement’s arguments, as evidenced in the writings and interviews of (...) its key leaders. Seeing their arguments and activities from this perspective highlights the danger to science posed by both ID Creationism and radical postmodernism. (shrink)

I consider what it might mean to teach creationism and offer a variety of educational, legal, religious, and philosophical arguments for why it is improper to teach it in public school science classes and possibly elsewhere as well. I rebut the standard creationist arguments for inclusion. I also rebut Rawlsian arguments offered by philosopher of religion Alvin Plantinga.

Drawing on Pennock’s theory of scientific virtues, we are developing an alternative curriculum for training scientists in the responsible conduct of research that emphasizes internal values rather than externally imposed rules. This approach focuses on the virtuous characteristics of scientists that lead to responsible and exemplary behavior. We have been pilot-testing one element of such a virtue-based approach to RCR training by conducting dialogue sessions, modeled upon the approach developed by Toolbox Dialogue Initiative, that focus on a specific virtue, e.g., (...) curiosity and objectivity. During these structured discussions, small groups of scientists explore the roles they think the focus virtue plays and should play in the practice of science. Preliminary results have shown that participants strongly prefer this virtue-based model over traditional methods of RCR training. While we cannot yet definitively say that participation in these RCR sessions contributes to responsible conduct, these pilot results are encouraging and warrant continued development of this virtue-based approach to RCR training.

In his keynote address at a recent Intelligent Design (ID) conference at Biola University, ID leader William Dembski began by quoting "a well-known ID sympathizer" whom he had asked to assess the current state of the ID movement. Dembski explained that he had asked because, "after some initial enthusiasm on his part three years ago, his interest seemed to have flagged" (Dembski 2002). The sympathizer replied that..

Key Words creation science, evolution education s Abstract Creationism, the rejection of evolution in favor of supernatural design, comes in many varieties besides the common young-earth Genesis version. Creationist attacks on science education have been evolving in the last few years through the alliance of different varieties. Instead of calls to teach “creation science,” one now finds lobbying for “intelligent design” (ID). Guided by the Discovery Institute’s “Wedge strategy,” the ID movement aims to overturn evolution and what it sees as (...) a pernicious materialist worldview and to renew a theistic foundation to Western culture, in which human beings are recognized as being created in the image of God. Common ID arguments involving scientific naturalism, “irreducible complexity,” “complex specified information,” and “icons of evolution,” have been thoroughly examined and refuted. Nevertheless, from Kansas to Ohio to the U.S. Congress, ID continues lobbying to teach the controversy, and scientists need to be ready to defend good evolution education. (shrink)

An exploration of the scientific mindset—such character virtues as curiosity, veracity, attentiveness, and humility to evidence—and its importance for science, democracy, and human flourishing. Exemplary scientists have a characteristic way of viewing the world and their work: their mindset and methods all aim at discovering truths about nature. In An Instinct for Truth, Robert Pennock explores this scientific mindset and argues that what Charles Darwin called “an instinct for truth, knowledge, and discovery” has a tacit moral structure—that it is important (...) not only for scientific excellence and integrity but also for democracy and human flourishing. In an era of “post-truth,” the scientific drive to discover empirical truths has a special value. Taking a virtue-theoretic perspective, Pennock explores curiosity, veracity, skepticism, humility to evidence, and other scientific virtues and vices. He explains that curiosity is the most distinctive element of the scientific character, by which other norms are shaped; discusses the passionate nature of scientific attentiveness; and calls for science education not only to teach scientific findings and methods but also to nurture the scientific mindset and its core values. Drawing on historical sources as well as a sociological study of more than a thousand scientists, Pennock's philosophical account is grounded in values that scientists themselves recognize they should aspire to. Pennock argues that epistemic and ethical values are normatively interconnected, and that for science and society to flourish, we need not just a philosophy of science, but a philosophy of the scientist.

Some philosophers suggest that the development of scientificknowledge is a kind of Darwinian process. The process of discovery,however, is one problematic element of this analogy. I compare HerbertSimon's attempt to simulate scientific discovery in a computer programto recent connectionist models that were not designed for that purpose,but which provide useful cases to help evaluate this aspect of theanalogy. In contrast to the classic A.I. approach Simon used, ``neuralnetworks'' contain no explicit protocols, but are generic learningsystems built on the model of (...) the interconnections of neurons in thebrain. I describe two cases that take the connectionist approach a stepfurther by using genetic algorithms, a form of evolutionary computationthat explicitly models Darwinian mechanisms. These cases show thatDarwinian mechanisms can make novel discoveries of complex, previouslyunknown patterns. With some caveats, they lend support to evolutionaryepistemology. (shrink)

What is the definition of life? Artificial life environments provide an interesting test case for this classical question. Understanding what such systems can tell us about biological life requires negotiating the tricky conceptual boundary between virtual and real life forms. Drawing from Wittgenstein’s analysis of the concept of a game and a Darwinian insight about classification, I argue that classifying life involves both causal and pragmatic elements. Rather than searching for a single, sharp definition, these considerations suggest that life is (...) a cluster concept with fuzzy boundaries and that there are multiple legitimate ways to make the notion precise for different scientific purposes. This pluralist, realist account avoids unnecessary border disputes by emphasizing how science negotiates such questions in relation to theory and evidence. I also discuss several objections to this approach, including a “moral hesitation” some have to allowing broader application of the concept of life to include artificial life. (shrink)

Could an ethical theory ever play a substantial evidential role in a scientific argument for an empirical hypothesis? InThe Descent of Man, Darwin includes an extended discussion of the nature of human morality, and the ethical theory which he sketches is not simply developed as an interesting ramification of his theory of evolution, but is used as a key part of his evidence for human descent from animal ancestors. Darwin must rebut the argument that, because of our moral nature, humans (...) are essentially different in kind from other animals and so had to have had a different origin. I trace his causal story of how the moral sense could develop out of social instincts by evolutionary mechanisms of group selection, and show that the form of Utilitarianism he proposes involves a radical reduction of the standard of value to the concept of biological fitness. I argue that this causal analysis, although a weakness from a normative standpoint, is a strength when judged for its intended purpose as part of an evidential argument to confirm the hypothesis of human descent.

Teach the Controversy? Kansas just can't get a break. In 1999, the state became an international laughingstock when creationists on the State Board of Education, led by Steve Abrams, gutted what would have been a model science curriculum, removing the theme of evolution as well as mentions of the Big Bang and the geological timescale (Pennock, 1999b, 2000). These board members and the creationist groups that assisted them seemed to confirm every stereotype of Kansas as an ignorant backwater. The creationists (...) lost their majority on the Board in the next election when sensible I~sans made their voices heard, and the standat'ds were righted. But freedom — in this case, freedom from the tyranny of ignorance— demands eternal vigilance, and science defenders were too quick to test on theit laurels. Another election passed and in 2005 Steve Abrams and his allies. were at.. (shrink)

Evolutionary algorithms typically use direct encodings, where each element of the phenotype is specified independently in the genotype. Because direct encodings have difficulty evolving modular and symmetric phenotypes, some researchers use indirect encodings, wherein one genomic element can influence multiple parts of a phenotype. We have previously shown that Hyper- NEAT, an indirect encoding, outperforms FT-NEAT, a direct-encoding control, on many problems, especially as the regularity of the problem increases. However, HyperNEAT is no panacea; it had difficulty accounting for irregularities (...) in problems. In this paper, we propose a new algorithm, a Hybridized Indirect and Direct encoding (HybrID), which discovers the regularity of a problem with an indirect encoding and accounts for irregularities via a direct encoding. In three different problem domains, HybrID outperforms HyperNEAT in most situations, with performance improvements as large as 40%. Our work suggests that hybridizing indirect and direct encodings can be an effective way to improve the performance of evolutionary algorithms. (shrink)

One new development in the ongoing creationism/ evolution controversy has been the proposal to institute optout policies that would allow creationist parents to exempt their children from any instruction involving evolution. By way of an explanation of some of the philosophical issues at play in the debate over evolution and the nature of science, this article shows the educational folly of such policies. If evolution is taught properly, it should not be possible to opt out of it without opting out (...) of biology. Moreover, if Intelligent Design creationist criticisms of evolution and scientific naturalism were taken as the basis for opting out, then the effect would be even more radical and would require opting out of science entirely.

��This paper investigates how an evolutionary al- gorithm with an indirect encoding exploits the property of phenotypic regularity, an important design principle found in natural organisms and engineered designs. We present the first comprehensive study showing that such phenotypic regularity enables an indirect encoding to outperform direct encoding con- trols as problem regularity increases. Such an ability to produce regular solutions that can exploit the regularity of problems is an important prerequisite if evolutionary algorithms are to scale to high-dimensional real-world (...) problems, which typically contain many regularities, both known and unrecognized. The indirect encoding in this case study is HyperNEAT, which evolves artificial neural networks (ANNs) in a manner inspired by concepts from biological development. We demonstrate that, in contrast to two direct encoding controls, HyperNEAT produces both regular behaviors and regular ANNs, which enables HyperNEAT to significantly outperform the direct encodings as regularity increases in three problem domains. We also show that the types of regularities HyperNEAT produces can be biased, allowing domain knowledge and preferences to be injected into the search. Finally, we examine the downside of a bias toward regularity. Even when a solution is mainly regular, some irregularity may be needed to perfect its functionality. This insight is illustrated by a new algorithm called HybrID that hybridizes indirect and direct encodings, which matched HyperNEAT’s performance on regular problems yet outperformed it on problems with some irregularity. HybrID’s ability to improve upon the performance of HyperNEAT raises the question of whether indirect encodings may ultimately excel not as stand-alone algorithms, but by being hybridized with a further process of refinement, wherein the indirect encoding produces patterns that exploit problem regu-.

We investigate the evolution of memory usage in environments where information about past experience is required for optimal decision making. For this study, we use digital organisms, which are self-replicating computer programs that are subject to mutations and natural selection. We place the digital organisms in a range of experimental environments: simple ones where environmental cues indicate that a specific action should be taken (e.g., turn left to find food) as well as slightly more complex ones where cues refer to (...) prior experience (e.g., repeat the action indicated by the previous cue). We demonstrate that flexible behaviors evolve in each of these environments, often leading to clever survival strategies. Additionally, memory usage evolves only when it provides a significant advantage and organisms will often employ surprisingly successful strategies that do not use memory. However, the most powerful strategies we found all made effective use of memory. (shrink)
