Intelligent design

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 12.203.22.146 (talk) at 14:38, 20 August 2005. The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This article is about the concept of intelligent design. See also the teleological argument. For the associated social movement see ID as a movement. For the book, see Intelligent Design (book).

Intelligent Design (or ID) is the controversial assertion promoted by a movement of the same name, that certain features of the universe and of living things exhibit the characteristics of a product resulting from an intelligent cause or agent. Most ID advocates state that their focus is on detecting evidence of design in nature, without regard to who or what the designer might be. However, ID advocate William Dembski in his book "The Design Inference"[1] lists God or an alien life force as two possible options.

The minority of scientists who support ID claim it has all the merits of a solid scientific theory. This claim is widely opposed by the majority of the scientific community. Despite ID sometimes being called Intelligent Design Theory, the scientific community does not recognise ID as a scientific theory and considers it to be creationist pseudoscience. The National Academy of Sciences has said, intelligent design "and other claims of supernatural intervention in the origin of life" are not science because their claims cannot be tested by experiment and propose no new hypotheses of their own. Critics argue that ID proponents find gaps within current evolutionary theory and fill them in with speculative beliefs. Both the Intelligent Design concept and the associated movement have come under considerable criticism. [2] This criticism is regarded by advocates of ID as a natural consequence of the cultural dominance of Darwinism built upon naturalism or materialistic presuppositions which preclude by definition the possibility of supernatural causes as rational scientific explanations.

There is some merit to this criticism. Since science is capable only of observation and measurement of material objects, it must necessarily be silent concerning the purpose of what is observed. Insofar as any theory posits the existence or absence of purpose, it is not science. Thus, evolutionary theory, while scientific in its measurements, is not science when it precludes by definition the possibility of purpose or design. Science can neither preclude nor include the study of purpose, it must remain silent on the subject.

Media organizations often focus on other qualities that the designer(s) in Intelligent Design theory might have in addition to intelligence, "higher power"[3], "unseen force"[4], etc.

Intelligent Design in summary

Intelligent Design was born out of opposition to the theory of evolution, and there are supporters who do not oppose the concept of evolution as a mechanism for directed change or for limited, undirected change. Its putative main purpose is to investigate whether or not the empirical evidence necessarily implies that life on Earth must have been designed by an intelligent agent or agents. For example, William Dembski, one of ID's leading proponents, has stated that the "fundamental claim" of ID is that "there are natural systems that cannot be adequately explained in terms of undirected natural forces and that exhibit features which in any other circumstance we would attribute to intelligence."

Dembski uses the example of Mt. Rushmore to provide an analogy to the underlying premise of ID:

"What about this rock formation convinces us that it was due to a designing intelligence and not merely to wind and erosion? Designed objects like Mt. Rushmore exhibit characteristic features or patterns that point us to an intelligence."--The Design Revolution, p. 33.

Proponents of ID look for evidence of what they call signs of intelligence — physical properties of an object that necessitate design. Examples being considered include irreducible complexity, information mechanisms, and specified complexity. Many design theorists believe that living systems show one or more of these signs of intelligence, from which they infer that life is designed. This stands in opposition to naturalistic theories of evolution, which attempt to explain life exclusively through natural processes such as random mutations and natural selection.

Critics call ID religious dogma repackaged in an effort to return creationism into public school science classrooms and note that ID features notably as part of the campaign known as Teach the Controversy. The National Academy of Sciences and the National Center for Science Education assert that ID is not science, but creationism.[5] While the scientific theory of evolution by natural selection has observable and repeatable facts to support it such as the process of mutations, gene flow, genetic drift, adaptation and speciation through natural selection, the "Intelligent Designer" in ID is neither observable nor repeatable. This violates the scientific requirement of falsifiability. It has also been charged that ID violates Occam's Razor by postulating an entity or entities to explain something that may have a simpler and scientifically supportable explanation not involving unobservable help.

ID proponent Behe concedes "You can't prove intelligent design by experiment". [6]

Critics say ID is attempting to redefine natural science,[7] and they cite books and statements of principal ID proponents calling for the elimination of "methodological naturalism" from science[8] and replace it with what critics call "methodological supernaturalism", which means belief in a transcendent, non-natural dimension of reality inhabited by a transcendent, non-natural deity.[9] Natural science uses the scientific method to create a posteriori knowledge based on observation alone (sometimes called empirical science). Critics of ID consider the idea that some outside intelligence created life on Earth to be a priori (without observation) knowledge. ID proponents cite complexity in nature that is not fully explained by the scientific method. (For instance, abiogenesis, the generation of life from non-living matter, is not understood scientifically, although some claim the first stages have been reproduced in the Miller-Urey experiment.)

This allegedly a priori inference that an intelligent designer (God or an alien life force[10]) created life on Earth has been compared to the a priori claim that aliens helped the ancient Egyptians build the pyramids[11]. In both cases, the effect of this outside intelligence is not repeatable, observable, or falsifiable, and it violates Occam's Razor as well. Conversely, proponents of ID point out that the inference that speciation has occurred through natural selection is likewise an inference, since it has never been observed in the laboratory either. Empirical scientists would simply say "we don't know exactly how the Egyptians built the pyramids" and list what is known about Egyptian construction techniques.

The design argument, precursor to ID

Further information: Teleological argument

Philosophers as far back as Plato have reasoned that the complexity of nature shows grounds for believing in supernatural design. The most notable forms of this argument were expressed by Thomas Aquinas in his Summa Theologica[12] (thirteenth century) and William Paley in his book Natural Theology (nineteenth century) where he makes the famous watchmaker analogy. According to intelligent design proponents, Intelligent Design is different from the design argument in one important respect: ID says nothing about who did the designing. It only seeks to know whether object X was designed, and pleads agnosticism on all questions of identity, purpose, or intent. [13]

The phrase "intelligent design", used in this sense, first appeared in Christian creationist literature, including the textbook Of Pandas and People (Haughton Publishing Company, Dallas, 1989). The term was promoted more broadly by the retired legal scholar Phillip E. Johnson following his 1991 book Darwin on Trial. Johnson is the program advisor of the Center for Science and Culture and is considered the father of the intelligent design movement.

Religion and leading ID proponents

Intelligent design arguments are carefully formulated in secular terms and intentionally avoid positing the identity of the designer. Phillip E. Johnson has stated that cultivating ambiguity by employing secular language in arguments which are carefully crafted to avoid overtones of theistic creationism is a necessary first step for ultimately introducing the Christian concept of God as the designer. Johnson emphasizes "the first thing that has to be done is to get the Bible out of the discussion" and that "after we have separated materialist prejudice from scientific fact." only then can "biblical issues" be discussed.[14] Johnson explicitly calls for ID proponents to obfuscate their religious motivations so as to avoid having ID recognized "as just another way of packaging the Christian evangelical message."[15] Though not all ID proponents are theistic or motivated by religious fervor, the majority of the principal ID advocates (including Michael Behe, William Dembski, Jonathan Wells, and Stephen C. Meyer) are Christians and have stated that in their view the designer of life is clearly God.

Similar mis-use of language on the evolutionist side has been noted by commentators such as Steve Kellmeyer[16]. Kellmeyer points out that while evolution claims to specifically exclude the possibility of purpose or design, the language used by evolution proponents regularly includes language whose definition require a designer. For example, the eminent evolutionist Richard Dawkin promotes his popular book entitled The Selfish Gene. The very definition of the adjective selfish in the title asserts exactly the purpose and design he claims to deny in the pages of the book.

ID as a movement

Further information: Intelligent design movement

The Intelligent Design movement is an organized campaign to promote ID arguments in the public sphere, primarily in the United States. The movement claims ID exposes the limitations of scientific orthodoxy, and of the secular philosophy of Naturalism. ID movement proponents allege that science, by relying upon methodological naturalism, demands an a priori adoption of a naturalistic philosophy that dismisses out of hand any explanation that contains a supernatural cause. Phillip E. Johnson, considered the father of the intelligent design movement and its unofficial spokesman stated that the goal of intelligent design is to cast creationism as a scientific concept:

"Our strategy has been to change the subject a bit so that we can get the issue of intelligent design, which really means the reality of God, before the academic world and into the schools."[17]
"This isn't really, and never has been a debate about science. It's about religion and philosophy."[18]

The intelligent design movement is largely the result of efforts by the conservative Christian think tank the Discovery Institute, and its Center for Science and Culture. The Discovery Institute's wedge strategy and its adjunct, the Teach the Controversy campaign, are campaigns intended to sway the opinion of the public and policymakers. They target public school administrators and state and federal elected representatives to introduce intelligent design into the public school science curricula and marginalize mainstream science. The Discovery Institute acknowledges that private parties have donated millions for a research and publicity program to "unseat not just Darwinism, but also Darwinism's cultural legacy."[19]

Critics note that instead of producing original scientific data to support ID’s claims, the Discovery Institute has promoted ID politically to the public, education officials and public policymakers. Also oft mentioned is that there is a conflict between what leading ID proponents tell the public through the media and what they say before their conservative Christian audiences, and that the Discovery Institute as a matter of policy obfuscates its agenda. This they claim is proof that the movement's "activities betray an aggressive, systematic agenda for promoting not only intelligent design creationism, but the religious worldview that undergirds it."[20]

Richard Dawkins, biologist and professor at Oxford University, compares "Teach the controversy" with teaching flat earthism, perfectly fine in a history class but not in science. "If you give the idea that there are two schools of thought within science, one that says the earth is round and one that says the earth is flat, you are misleading children." [21]

ID in US politics

Underscoring claims that the ID movement is more social and political enterprise and less a scientific one, Intelligent Design has featured in a number of controversial political cases. These are discussed in greater depth in the main Intelligent design movement article.

  • 2000 Congressional briefing In 2000, the leading ID proponents operating through the Discovery Institute held a congressional briefing in Washington, D.C., to promote ID to lawmakers. Sen. Rick Santorum was and continues to be one of ID's most vocal supporters. One result of this briefing was that Sen. Santorum inserted pro-ID language into the No Child Left Behind bill calling for students to be taught why evolution "generates so much continuing controversy," an assertion heavily promoted by the Discovery Institute.
  • 2001 Santorum Amendment The Discovery Institute played a central role in the inclusion of pro-ID language known as the Santorum Amendment in the Conference Report of the federal No Child Left Behind education act. Though the amendment lacks the weight of law, its inclusion in the conference report is constantly cited by the Discovery Institute and other ID supporters as providing federal sanction for intelligent design.
  • 2001 & 2004 Pennsylvania Board of Education In 2001 the Pennsylvania Board of Education approved revised science standards that raised questions about the status of evolution as science and a theory. In 2004, the Dover, Pennsylvania Board of Education passed a law requiring the teaching of intelligent design. A challenge was filed contending that the law violates the First Amendment. A hearing in Federal District Court is scheduled for September 2005.
  • 2002 Ohio Board of Education The Discovery Institute proposed a model lesson plan that featured intelligent design prominently in its curricula. It was adopted in part in October 2002, with the Board's advising that the science standards do "not mandate the teaching or testing of intelligent design." Still, this has been touted by the Discovery Institute as a significant victory.

Intelligent design debate

Template:ID The intelligent design debate centers on three issues:

  1. whether the definition of science is broad enough to allow for theories of human origins which incorporate the acts of an intelligent designer
  2. whether the evidence supports such theories
  3. whether the teaching of such theories is appropriate in public education.

ID supporters generally hold that science must allow for both natural and supernatural explanations of phenomena. Excluding supernatural explanations limits the realm of possibilities, particularly where naturalistic explanations utterly fail to explain certain phenomena. Supernatural explanations provide a very simple and parsimonious explanation for the origins of life and the universe. Proponents claim that the evidence strongly supports such explanations, as instances of so-called irreducible complexity and specified complexity appear to make it highly unreasonable that the full complexity and diversity of life came about solely through natural means. Finally, they hold that religious neutrality requires the teaching of both evolution and intelligent design in schools, because teaching only evolution unfairly discriminates against those holding the Creationist beliefs. Teaching both, ID supporters argue, allows for a scientific basis for religious belief, without causing the state to actually promote a religious belief.

According to critics of ID, not only has ID failed to establish reasonable doubt in its proposed shortcomings of accepted scientific theories, but it has not even presented a case worth taking seriously. Critics of ID argue that ID has not presented a credible case for the public policy utility of presenting Intelligent Design in education. More broadly, critics maintain that it has not met the minimum legal standard of not being a "clear" attempt to establish religion, which in the United States is forbidden by law. Scientists argue that those advocating "scientific" treatment of "supernatural" phenomena are grossly misunderstanding the issue, and indeed misunderstand the nature and purpose of science itself.

Between these two positions there is a large body of opinion that does not condone the teaching of what is considered unscientific or questionable material, but is generally sympathetic to the position of Deism/Theism and therefore desires some compromise between the two. The nominal points of contention are seen as being proxies for other issues. For example Richard Dawkins, a very prominent spokesman for evolutionary theory, has argued that evolution disproves the existence of God. Many ID followers are quite open about their view that "Scientism" is itself a religion that promotes secularism and materialism in an attempt to erase religion from public life and view their work in the promotion of ID as a way to return religion to a central role in education and other public spheres. Some allege that this larger debate is often the subtext for arguments made over Intelligent Design, though others note that ID serves as an effective proxy for the religious beliefs of prominent ID proponents in their efforts to advance their religious point of view within society. [22][23][24]

Irreducible complexity

Further information: Irreducible complexity

The term was coined by biochemist Michael Behe in his 1996 book Darwin's Black Box. The irreducible complexity argument holds that evolutionary mechanisms cannot account for the emergence of some complex biochemical cellular systems. ID advocates argue that the systems must therefore have been deliberately engineered by some form of intelligence. Irreducible complexity is defined by Behe as:

"...a single system which is composed of several well-matched interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning."--(Behe, Molecular Machines: Experimental Support for the Design Inference).

According to the theory of evolution, genetic variations occur without specific design or intent. The environment selects variants that have the highest fitness, which are then passed on to the next generation of organisms. Change occurs by the gradual operation of natural forces over time, perhaps slowly, perhaps more quickly (see punctuated equilibrium). This process is able to create complex structures from simpler beginnings, or convert complex structures from one function to another (see spandrel). Most ID advocates accept that evolution through mutation and natural selection occurs, but assert that it cannot account for irreducible complexity, because none of the parts of an irreducible system would be functional or advantageous until the entire system is in place.

Behe uses the mousetrap as an illustrative example of this concept. A mousetrap consists of several interacting pieces—the base, the catch, the spring, the hammer—all of which must be in place for the mousetrap to work. The removal of any one piece destroys the function of the mousetrap. Likewise, biological systems require multiple parts working together in order to function. ID advocates claim that natural selection could not create from scratch those systems for which science is currently not able to find a viable evolutionary pathway of successive, slight modifications, because the selectable function is only present when all parts are assembled. Behe's original examples of irreducibly complex mechanisms included the bacterial flagellum of E. coli, the blood clotting cascade, cilia, and the adaptive immune system.

Criticism
Critics of ID point out that the IC argument only makes sense if one assumes that the present function of a system must have been the one that it was selected for. But the concept of co-optation or exaptation, in which existing features become adapted for new functions, has long been a mainstay of biology. Many purported IC structures have functional subsystems that are used elsewhere. ID advocates have often reacted to this by trying to define an "IC core", or by changing the number of parts required for an IC system. Critics have claimed that these instances of "moving the goal posts" show that IC is not a clear concept that can be objectively applied. While Behe has considered co-optation, he rejects it as unlikely, which critics contend is an unwarranted dismissal.
The IC argument also assumes that the necessary parts of a system have always been necessary, and therefore could not have been added sequentially. But something which is at first merely advantageous can later become necessary. For example, one of the clotting factors that Behe listed as a part of the IC clotting cascade was later found to be absent in whales[25], demonstrating that it isn't essential for a clotting system. Many purported IC structures can be found in other organisms as simpler systems that utilize fewer parts. These systems may have had even simpler precursors that are now extinct.
Perhaps most importantly, potentially viable evolutionary pathways have been proposed for IC systems such as blood clotting, the immune system[26] and the flagellum[27], which were the three examples Behe used. Even his example of a mousetrap was shown to be reducible by John H. McDonald (A reducibly complex mousetrap). If IC is an insurmountable obstacle to evolution, it should not be possible to conceive of such pathways—Behe has remarked that such plausible pathways would defeat his argument. It has also been claimed that computer simulations of evolution demonstrate that IC can evolve[28]. ID advocates respond by saying that proposed models for the evolution of IC structures are not detailed enough, or cannot be tested. They also dismiss such computer simulations as being fundamentally flawed[29] and biologically unrealistic.

Specified complexity

Further information: Specified complexity

The ID concept of specified complexity was developed by mathematician, philosopher, and theologian William Dembski. Dembski claims that when something exhibits specified complexity (i.e., is both complex and specified, simultaneously) one can infer that it was produced by an intelligent cause (i.e., that it was designed), rather than being the result of natural processes. He provides the following examples: "A single letter of the alphabet is specified without being complex. A long sentence of random letters is complex without being specified. A Shakespearean sonnet is both complex and specified." (Intelligent Design, p. 47) He states that details of living things can be similarly characterized, especially the "patterns" of molecular sequences in functional biological molecules such as DNA.

Dembski defines a probability of 1 in 10150 as the "universal probability bound". Its value corresponds to the inverse of the upper limit of "the total number of [possible] specified events throughout cosmic history," as calculated by Dembski. (The Design Revolution, p. 85) He defines complex specified information (CSI) as specified information with a probability less than this limit. (The terms "specified complexity" and "complex specified information" are used interchangeably.) He argues that CSI cannot be generated by the only known natural mechanisms of physical law and chance, or by their combination. He argues that this is so because laws can only shift around or lose information, but do not produce it, and chance can produce complex unspecified information, or unspecified complex information, but not CSI; he provides a mathematical analysis that he claims demonstrates that law and chance working together cannot generate CSI, either. Dembski and other proponents of ID argue that CSI is best explained as being due to an intelligent cause and is therefore a reliable indicator of design.

Criticism
Martin Nowak, a Harvard professor of mathematics and evolutionary biology argues that ID "cannot calculate the probability that an eye came about. We don't have the information to make the calculation." [30]
The conceptual soundness of Dembski's specified complexity/CSI argument is strongly disputed by critics of ID. First, critics maintain that Dembski confuses the issue by using "complex" as most people would use "improbable". He defines CSI as anything with a less than 1 in 10150 chance of occurring by (natural) chance. Critics claim that this renders the argument a tautology: CSI cannot occur naturally because Dembski has defined it thus, so the real question becomes whether or not CSI actually exists in nature. They claim that Dembski does not attempt to demonstrate this, but instead simply takes the existence of CSI as a given, and then proceeds to argue that it is a reliable indicator of design.
Another criticism of specified complexity refers to the problem of "arbitrary but specific outcomes". For example, it is unlikely that any given person will win a lottery, but, eventually, a lottery will have a winner; to argue that it is very unlikely that any one player would win is not the same as proving that there is the same chance that no one will win. Similarly, it has been argued that "a space of possibilities is merely being explored, and we, as pattern-seeking animals, are merely imposing patterns, and therefore targets, after the fact."[31] Critics also note that there is much redundant information in the genome, which makes its content much lower than the number of base pairs used.

Fine-tuned universe

Further information: Fine-tuned universe

ID proponents use the argument that we live in a fine-tuned universe. They propose that the natural emergence of a universe with all the features necessary for life is wildly improbable. Thus, an intelligent designer of life was needed to ensure that the requisite features were present to achieve that particular outcome. Opinion within the scientific community is still divided on the "finely-tuned universe" issue, but this particular explanation and assessment of probabilities is rejected by most scientists and statisticians.

Within mainstream physics this is related to the question of the anthropic principle, whose weak form is based on the observation that the laws of physics must allow for life, since we observe there is life. The strong form, however, is the assertion that the laws of physics must have made it possible for life to arise. The strong form is a distinctly minority position and is highly controversial.

Criticism
Critics of both ID and the weak form of anthropic principle argue that they are essentially a tautology; life as we know it may not exist if things were different, but a different sort of life might exist in its place. The claim of the improbability of a life-supporting universe has also been criticized as an argument by lack of imagination for assuming no other forms of life are possible (see also carbon chauvinism).
Based on the unproven idea that some of the universe's initial conditions might have been different, Stephen Hawking and James Hartle have shown that from the initial conditions of the universe, that is, the moment immediately after the Big Bang, a large number of types of universe could have formed. The type of universe that we live in is called a Hartle-Hawking type universe. According to their calculations, the chance that a Hartle-Hawking universe forms is over 90%. Thus, the chance that our particular universe formed may be small, but the chance that a universe of the same type, with stars, planets and the other elements required to create life as we know it would come out of the Big Bang is over 90%, not improbable at all.
Recent work in cosmology has put forth the mathematical possiblity of a multiverse. This would allow many types of universes to simultaneously arise, of which ours is one possibility. Although multiverse theories currently lack verified predictions, some astronomers believe that gravity may leak into other dimensions in braneworld scenarios, potentially providing the first observable data to support these theories.

Additional Criticisms of ID

Scientific peer review

Dembski has written that "Perhaps the best reason [to be skeptical of his theory] is that intelligent design has yet to establish itself as a thriving scientific research program."[32] Critics argue that ID proponents either do not submit articles to peer reviewed journals, or set up "peer review" that consists entirely of ID supporters. Proponents of ID explain the reason for their absence in peer-reviewed literature is that papers explaining the findings and concepts in support of ID are consistently excluded from the mainstream scientific discourse. They claim this is because ID arguments challenge the principles of philosophical naturalism and uniformitarianism that are accepted as fundamental by the mainstream scientific community. Thus, ID supporters believe that research that points toward an intelligent designer is often rejected simply because it deviates from these "dogmatically held beliefs", without regard to the merits of their specific claims.

According to their critics, this is an ad hominem attack, designed to cover over the lack of success in creating scientifically testable or verifiable data or theory, by claiming that there is a conspiracy against them. Critics of ID point out that this is an argument commonly used by advocates of pseudoscientific views (most notably by UFO enthusiasts), and that the perceived bias is simply the result of ID being unscientific and inadequately supported. A notable exception to this explanation for lack of published, peer-reviewed writings is William Dembski, who claims in a 2001 interview that he stopped submitting to peer-reviewed journals due to their slow time-to-print and that he makes more money from publishing books[33].

To date, the intelligent design movement has yet to publish an article in a peer-reviewed scientific journal. On 4 August, 2004, an article by Stephen C. Meyer, Director of Discovery Institute's Center for Science & Culture appeared in the peer reviewed journal, Proceedings of the Biological Society of Washington.[34] On 7 September, the publisher of the journal, the Council of the Biological Society of Washington, released a statement repudiating the article as not meeting its scientific standards and not peer reviewed. The same statement vowed that proper review procedures would be followed in the future and endorsed a resolution published by the American Association for the Advancement of Science,[35] which observes that there is no credible scientific evidence supporting ID. The journal's reasons for disavowing the article was denied by Richard Sternberg, who was managing editor at the time the article was submitted and subsequently left the at its' time of publication.[36] Critics of Meyer's paper believe that Sternberg himself was biased in the matter, since he is a member of the editorial board of the Baraminology Study Group, an organization with a creationist agenda. The Baraminology Study Group's official position is that Sternberg is not a creationist and acts primarily as a skeptical reviewer.[37] A critical review of the article is available on the Panda's Thumb website[38].

ID proponents have also claimed as proof of peer review an article by Michael Behe and David W. Snoke was published in the journal Protein Science. But the paper has been critiqued by qualified scientists, who point out that "it contains no 'design theory,' makes no attempt to model an 'intelligent design' process, and proposes no alternative to evolution."

The vast majority of practicing biologists do not support or otherwise endorse intelligent design. The scientific community does not regard the argument over ID to be of the same kind as, for example, differing theories on how particular traits evolved, or even in the realm of scientific speculation, the way, a hypothesis of exogenesis might be considered as a plausible scientific speculation. The failure to follow the procedures of scientific discourse, and the failure to submit work to the scientific community which withstands scrutiny is regarded by the critics of ID as a strong argument against intelligent design being considered as "science" at all.

Hypotheses about the designer(s)

Although the Intelligent Design movement is often portrayed as a variant of Bible-based Creationism, many ID arguments are formulated in secular terms. Most ID arguments do not depend on Biblical fundamentalism. They do not explicitly state that their adherents accept the Bible's accounts, they do not explicitly state that God is the designer, but the designer is often implicitly hypothesized to have intervened at so many different points in time and space (sometimes even outside of time and space in the case of the fine-tuned universe designer) that only God or an extremely capable, long-lived and persistent alien culture could fulfill the requirements.

Each hypothesized design poses a new challenge for ID. Is the new design a product of the same designer(s) as any other design, based on external evidence, or evidence internal to the design. Each design, based on the evidence for the original time and place of the appearance of that design, hypotheses that the same or different designers must have been present at that place and time. Since the places and times are often only known imprecisely, there is the possibility that they may coincide with those of some other designs.

The key arguments in favor of the different variants of ID are so broad that they can be adopted by any number of communities that seek an alternative to evolutionary thought, including those that support non-theistic models of creation although the designers might be different. For example, the notion of an "intelligent designer" is compatible with the materialistic hypotheses that life on Earth was introduced by an alien species, or that it emerged as a result of panspermia, but would not be with the designer(s) of the "fine-tuned" universe. Likewise, ID claims can support a variety of theistic notions. Some proponents of creationism and intelligent design reject the Christian concept of omnipotence and omniscience on the part of God, and subscribe to Open Theism or Process theology. It has been suggested by opponents that ID researchers must explain why organisms were designed as they were, and argue that existing evidence makes the design hypothesis appear unlikely. For example, Jerry Coyne, of the University of Chicago, asks:

Would an intelligent designer create millions of species and then make them go extinct, only to replace them with other species, repeating this process over and over again? ... Why did the designer give tiny, non-functional wings to kiwi birds? Or useless eyes to cave animals? Or a transitory coat of hair to a human fetus?... Why would the designer give us a pathway for making vitamin C, but then destroy it by disabling one of its enzymes? Why didn't the intelligent designer stock oceanic islands with reptiles, mammals, amphibians, and freshwater fish, despite the suitability of such islands for these species? And why would he make the flora and fauna on those islands resemble that of the nearest mainland, even when the environments are very different?[39]

Some of these ID researchers would instead argue that we are simply incapable of understanding the designer's motives. For example Behe argued in Darwin's Black Box that

Features that strike us as odd in a design might have been placed there by the designer for a reason--for artistic reasons, to show off, for some as-yet undetectable practical purpose, or for some unguessable reason

Additionally, they may argue that the creator's benevolence does not imply the need for physical perfection in Creation. Critics like Coyne respond that the possibility of mutually contradictory and "unguessable" motives for the designer mean that ID is not falsifiable and therefore not scientific.

"What designed the designer?"

By raising the question of the need for a designer for objects with irreducible complexity, ID also raises the question, "what designed the designer?" By ID's own arguments, a designer capable of creating irreducible complexity must also be irreducibly complex. Unlike with religious creationism, where the question "what created God?" can be answered with theological arguments, this creates a logical paradox, as the chain of designers can be followed back indefinitely, leaving the question of the creation of the first designer dangling. The sort of logic required in sustaining such reasoning is known as circular reasoning; a form of logical fallacy.

One ID counter-argument to this problem invokes an uncaused causer - in other words, a deity - to resolve this problem, in which case ID reduces to religious creationism. At the same time, the postulation of the existence of even a single uncaused causer in the Universe contradicts the fundamental assumption of ID that a designer is needed for every complex object. Another possible counter-argument might be an infinite regression of designers. However, admitting infinite numbers of objects also allows any arbitarily improbable event to occur, such as an object with "irreducible" complexity assembling itself by chance. Again, this contradicts the fundamental assumption of ID that a designer is needed for every complex object, producing a logical contradiction.

Thus, according to opponents, either attempt to patch the ID hypothesis appears to either result in logical contradiction, or reduces it to a belief in religious creationism. ID then ceases to be a falsifiable theory and loses its ability to claim to be a scientific theory.

Richard Dawkins, biologist and professor at Oxford University, argues that intelligent design simply takes the complexity required for life to have evolved and moves it to the "designer" instead. ID doesn't explain how the complexity happened in the first place, it just moves it. [40]

Argument from ignorance

Some critics have argued that many points raised by Intelligent Design proponents strongly resemble arguments from ignorance. In the argument from ignorance, one claims that the lack of evidence for one view is evidence for another view (e.g. "Science cannot explain this, therefore God did it"). Particularly, Michael Behe's demands for ever more detailed explanations of the historical evolution of molecular systems seem to assume a dichotomy where either evolution or design is the proper explanation, and any perceived failure of evolution becomes a victory for design. In scientific terms, "absence of evidence is not evidence of absence" for naturalistic explanations of observed traits of living organisms.
