_Anthropic Bias_ explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and (...) paradoxes: the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ; evolutionary theory ; the problem of time's arrow ; quantum physics ; game-theory problems with imperfect recall ; even traffic analysis. _Anthropic Bias_ argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox. (shrink)

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle (...) asserts that "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

The anthropic principle, that the universe exists in some sense for life, has persisted in recent religious and scientific thought because it derives from cosmological fact. It has been unsuccessful in furthering our understanding of the world because its advocates tend to impose final metaphysical solutions onto what is a physical problem. We begin by outlining the weak and strong versions of the anthropic principle and reviewing the discoveries that have led to their formulation. We present the reasons (...) some have given for ignoring the anthropic implications of these discoveries and find these reasons wanting—a real phenomenon demands real investigation. Theological and scientific solutions of the problem are then considered and criticized; these solutions provide dead ends for explanation. Finally, we pursue the path that explanation must follow and look at the physical details of the problem. It seems clear that the anthropic principle has been poorly framed. Removing the ambiguities surrounding the meaning of “life” may lead to more profitable investigations. (shrink)

The paper considers the philosophical component of the approach to the time as an emergent phenomenon absent at the fundamental level. The anthropic principle is shown as arising from the time emergence. Consciousness is shown as an epiphenomenon in such a model, although it is more fundamental than matter in this case. An answer to the question about the prime cause is suggested.

We describe a significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events. The risks associated with catastrophes such as asteroidal/cometary impacts, supervolcanic episodes, and explosions of supernovae/gamma-ray bursts are based on their observed frequencies. As a result, the frequencies of catastrophes that destroy or are otherwise incompatible with the existence of observers are systematically underestimated. We describe the consequences of the anthropic bias for estimation of catastrophic risks, and suggest some (...) directions for future work. (shrink)

The claims of some authors to have introduced a new type of explanation in cosmology, based on the anthropic principle, are examined and found wanting. The weak anthropic principle is neither anthropic nor a principle. Either in its direct or in its Bayesian form, it is a mere tautology lacking explanatory force and unable to yield any prediction of previously unknown results. It is a pattern of inference, not of explanation. The strong anthropic principle is a (...) gratuitous speculation with no other support than previous religious commitment or the assumption of an actual infinity of universes, for which there is no the slightest empirical hint. But even assuming so much, it does not work. In particular, the assumption of an infinity of different universes is no guarantee of finding among them one like this one. The loose anthropic way of reasoning does not stand up to the usual methodological standards of empirical science. And it does not signal any anthropocentric turn in contemporary science. (shrink)

Natural kind concepts have the function of tracking categories that exist independently of our beliefs and purposes. But not all ways of tracking categories in the natural world involve conceiving of them as natural kinds. Anthropic concepts represent groups of natural, mind‐independent entities that are apt for serving various human interests, goals, and projects. They represent the natural world under a practical mode of presentation, as a set of material resources that can be transformed to further a host of (...) functions and ends. I argue that cross‐cultural studies of traditional ecological knowledge provide evidence that many chemical, mineral, and biological concepts that are frequently taken to be natural kind concepts turn out on closer inspection to be anthropic concepts. Anthropic concepts are distinguished from artifact concepts, and a form of realism about the anthropic kinds that they refer to is defended. (shrink)

Some arguments against David Lewis’s modal realism seek to exploit apparent inconsistencies between it and anthropic reasoning. A recent argument, in particular, seeks to exploit an inconsistency between modal realism and typicality anthropic premises, premises common in the literature on physical multiverses, to the effect that observers who are like human observers in certain respects must be typical in the relevant multiverse. Here I argue that typicality premises are not applicable to the description of Lewis’s metaphysical multiverse, where (...) the proportions of metaphysically possible observers possessing the pertinent properties can be independently established by metaphysical reasoning. However, other kinds of reasonable anthropic premises can be seen to be consistent with and usable within modal realism. (shrink)

We grant that anthropic reasoning yields the result that we should not expect to be in a small civilization. However, regardless of what civilization one finds oneself in, one can use anthropic reasoning to get the result that one should not expect to be in that sort of civilization. Hence, contra Ken Olum, anthropic reasoning does not conflict with observation.

In a recent study of astrophysical “fine-tunings” (or “coincidences”), Robert Klee critically assesses the support that such astrophysical evidence might be thought to lend to the design argument (i.e., the argument that our universe has been designed by some deity). Klee argues that a proper assessment indicates that the universe is not as “fine-tuned” as advertised by proponents of the design arguments. We argue (i) that Klee’s assessment of the data is, to a certain extent, problematic; and (ii) even if (...) Klee’s assessment of the data is correct, it provides a necessary but not a sufficient response to the design argument. However, an adequate skeptical rejoinder to the design argument can be made by appealing to the anthropic principle. (shrink)

Cosmologists using the Anthropic Principle claim that if our universe had been much different then nobody would exist to observe it. This may become explanatory when one accepts the actual existence of multiple "universes": gigantic, largely or entirely separate systems having very varied properties. Ian Hacking has urged, though, that an Inverse Gambler's Fallacy is committed during many attempts to formulate anthropic explanations. Besides disagreeing with him, the paper makes several further points in support of such explanations, in (...) particular against the background of the Inflationary Universe. (shrink)

The Anthropic Principle suggests that the universe may have been designed for human life. This anthropocentric, anti-Copernican, notion elicits a variety of responses from scientists, including some elaborate attempts to invalidate it by trying to show that there may be an infinity of alternative universes. These attempts may be challenged as unreasonably speculative and presumptive. What emerges is the suggestion that cosmology may at last be in possession of some raw material for a postmodern creation myth. If the (...) class='Hi'>Anthropic Principle can be integrated with biological explanations of human origins, and the result joined to the traditional Biblical Creation story, what emerges is a possible recovery of a religiously traditional, yet scientifically coherent, creation story for our generation.

The case of Fred Hoyle’s prediction of a resonance state in carbon-12, unknown in 1953 when it was predicted, is often mentioned as an example of anthropic prediction. However, an investigation of the historical circumstances of the prediction and its subsequent experimental confirmation shows that Hoyle and his contemporaries did not associate the level in the carbon nucleus with life. Only in the 1980s, after the emergence of the anthropic principle, did it become common to see Hoyle’s prediction (...) as anthropically significant. At about the same time mythical accounts of the prediction and its history began to abound. Not only has the anthropic myth no basis in historical fact, it is also doubtful if the excited levels in carbon-12 and other atomic nuclei can be used as an argument for the predictive power of the anthropic principle.

The Argument from Fine-Tuning, a relatively new version of the Design Argument, has given rise to an objection, based on what is known as the An­thropic Principle. It is alleged that the argument is fallacious in that it involves an observation selection effect—that given the existence of intelligent living observers, the observation that the universe is fine-tuned for the existence of intelligent life is not surprising. Many find this objection puzzling, or at least easily refutable. My main contribution to the (...) discussion is to offer an analysis of what is wrong (and what is right) in the objection. (shrink)

Democracy in its currently dominant liberal form has proven supportive of unprecedented human flourishing. However, it also appears increasingly plagued by political polarization, strained to cope with the digitalization of the political discourse, and threatened by authoritarian backlash. A growing sense of the anthropic risks—with runaway climate change as the leading example—thus often elicits concern regarding democracy’s capability of mitigating them. Apparently, lacking a sufficient degree of the citizens’ consensus on the priority issues of the day, it can find (...) itself unable to muster the resolve and resources necessary to alter its “business as usual” path even where disasters loom ever larger in its track. Against these concerns, I argue that democracy’s potential remains far from depleted. While political irrationality needs to be considered a major obstacle to successfully managing the anthropic risks, many existing reform proposals appear capable of reining it in. My main suggestion is to seek ways to facilitate a speedier and more effective exploration of the landscape of the possible democratic mechanisms of collective choice. A virtual platform to support such an exploration—which I call ‘democracy’s digital playground’—may allow us to find innovative ways of managing anthropic risks without compromising our commitment to democratic values.

John D. Barrow and Frank J. Tipler's recently published Anthropic Cosmological Principle is an encyclopedic defense of melioristic evolutionary cosmology. They review the history of the idea from ancient times to the present, and defend both a “weak” version, and two “strong” versions of the anthropic principle. I argue the weak version of the anthropic principle is true and important, but that neither of the two strong versions are well grounded in fact. Their “final” anthropic principle (...) is a revision of Teilhard de Chardin's evolutionary cosmology. They rectify Teilhard's factual errors but commit even more serious psychological and religious errors of their own. (shrink)

A modern assessment of the classical Boltzmann-Schuetz argument for large-scale entropy fluctuations as the origin of our observable cosmological domain is given.The emphasis is put on the central implication of this picture which flatly contradicts the weak anthropic principle as an epistemological statement about the universe. Therefore, to associate this picture with the anthropic principle as it is usually done is unwarranted. In particular, Feynman's criticism of theanthropic principle based on the entropy-fluctuation picture is a product of this (...) semantic confusion. (shrink)

Anthropic reasoning has lately been strongly associated with the string theory landscape and some theories of particle cosmology, such as cosmological inflation. The association is not, contrary to multiple statements by physicists and philosophers alike, necessary. On the contrary, there are clear reasons and instances in which the anthropic reasoning is useful in a diverse range of fields such as planetary sciences, geophysics, future studies, risk analysis, origin of life studies, evolutionary theory, astrobiology and SETI studies, ecology, or (...) even strategic studies and global policy. The association of anthropic reasoning with string theory and particle cosmology has not only become the standard wisdom, but has been often construed in a negative way, in order to demonstrate or insinuate that such reasoning is too abstract or even belongs to “fringe science”, remote from run-of-the-mill research practices in any other more “mundane” and less theoretical scientific discipline. The purpose of this paper is to analyse some of the counter-examples to the standard wisdom, suggest that the anthropic reasoning is more flexible, more general, and less fashion-driven than the detractors state. In addition, we consider some historical and/or extrascientific motivation for this persistent prejudice. (shrink)

The questions that were purely in the realms of philosophy are now beginning to be answered by science. The second Venice Conference on Cosmology and Philosophy explores the anthropic principle which states that the Universe has the conditions we observe because we are here. Out of all possible universes we can only experience the restricted class that permits observers. This realization has profound implications for cosmology, philosophy and theology; all of which are explored in this book by thirteen contributors (...) who gathered to discuss and share their theories within the context of science. The result is a unique collection of papers of great value to professional astronomers and philosophers interested in the role of observers in the Universe. (shrink)

Philosophy part of theory of emergent space-time-matter is discussed. It was shown that anthropic principle is direct consequence of emergent time. It was shown that consciousness is epiphenomenon, but it is more fundamental than matter.

Anthropic arguments in multiverse cosmology and string theory rely on the weak anthropic principle (WAP). We show that the principle, though ultimately a tautology, is nevertheless ambiguous. It can be reformulated in one of two unambiguous ways, which we refer to as WAP_1 and WAP_2. We show that WAP_2, the version most commonly used in anthropic reasoning, makes no physical predictions unless supplemented by a further assumption of "typicality", and we argue that this assumption is both misguided (...) and unjustified. WAP_1, however, requires no such supplementation; it directly implies that any theory that assigns a non-zero probability to our universe predicts that we will observe our universe with probability one. We argue, therefore, that WAP_1 is preferable, and note that it has the benefit of avoiding the inductive overreach characteristic of much anthropic reasoning. (shrink)

In contemporary cosmology, from the creation of the General Theory of Relativity to the second half of the twentieth century, the main task of cosmologists was to construct and test cosmological models of the Universe.

If God is morally perfect then He must perform the morally best actions, but creating humans is not the morally best action. If this line of reasoning can be maintained then the mere fact that humans exist contradicts the claim that God exists. This is the ‘anthropic argument’. The anthropic argument, is related to, but distinct from, the traditional argument from evil. The anthropic argument forces us to consider the ‘creation question’: why did God not create other (...) gods rather than humans? That is, if God is omniscient, omnipotent, and morally perfect then why didn’t He create a world populated exclusively by beings that are perfect in the same way that He is—ontological equivalents— rather than choosing to create humans with finite natures and all the suffering that this entails?

The successes scored by the big bang model of cosmic evolution in the 1960’s led to an intensive application of quantum theory to the problem of how the expansion might have begun and what its likely first stages were. It seemed as though an incredibly precise setting of the initial conditions would have been needed in order that a long-lived galactic universe containing heavy elements might develop. One response was to suppose that the fine-tuning could somehow be explained by the (...) presence of humans in the universe. This ran quite counter to the traditional supposition, according to which an initial "chaos" was sufficient. This essay outlines the history of the two principles, argues that the so-called "weak" anthropic principle is banal, distinguishes between two sorts of anthropic explanation, and assesses the prospects of the anthropic turn in cosmology.

The structure of the universe and of most objects in it is determined by a small number of physical constants. It can be shown that only a limited range of values for each of these constants is compatible with the existence of human life. The fact that we are able to exist--but just barely--calls for an explanation. In the last fifteen years, an "anthropic principle" has been proposed as a possible scientific explanation of the fortuitous features of our world. (...) This type of explanation focuses on ways in which the presence of human beings guarantees that conditions in the early universe be suitable for the eventual development of intelligent life. In its strongest form, the anthropic principle is teleological: the universe is habitable precisely so that humans can evolve in it. ;Many issues surrounding the principle and its role in contemporary cosmology have been widely misunderstood by physicists and philosophers alike. My project is to clarify the nature of the principle and to criticize its value as a scientific claim. In chapters 1 and 2, I discuss the principle's historical background, and differentiate between several distinct ideas often misleadingly categorized as "anthropic." In chapter 3, after considering the principle's scientific justification, I conclude that it is neither essentially anthropic nor capable of predictive success. In chapter 4, I argue that the principle has little, if any, explanatory power, even in its teleological form. Having put fourth a number of criticisms of the principle as a scientific principle, in the final chapter I look at the possibility of construing it in a theistic context. Although the principle is not usually considered a religious principle, its resemblance to premises used in traditional theistic arguments from design suggests that it may be more defensible if thought of in a theistic context.

The evolutionary origin of consciousness has been a growing area of study in recent years. Nevertheless, there is intense debate on whether the existence of phenomenal consciousness without the cerebral cortex is possible. The corticocentrists have an empirical advantage because we are quasi-confident that we humans are conscious and have the well-developed cortex as the site of our consciousness. However, their prejudice can be an anthropic bias similar to the anthropocentric prejudice in pre-Darwinian natural history. In this paper, I (...) propose three basic principles to provide a conceptual basis for evolutionary studies of consciousness: the non-solipsistic principle, the evolution principle, and the anthropic principle. These principles collectively help us to avoid solipsism, anthropocentrism, and anthropomorphism to some degree, although we cannot be completely free from them. Also, the landscape metaphor associated with the anthropic principle provides an image of how different forms of consciousness can be acquired. (shrink)

In the last three decades several cosmological principles and styles of reasoning termed 'anthropic' have been introduced into physics research and popular accounts of the universe and human beings' place in it. I discuss the circumstances of 'fine tuning' that have motivated this development, and what is common among the principles. I examine the two primary principles, and find a sharp difference between these 'Weak' and 'Strong' varieties: contrary to the view of the progenitors that all anthropic principles (...) represent a departure from Copernicanism in cosmology, the Weak Anthropic Principle is an instance of Copernicanism. It has close affinities with the step of Copernicus that Immanuel Kant took himself to be imitating in the 'critical' turn that gave rise to the Critique of Pure Reason. I conclude that the fact that a way of going about natural science mentions human beings is not sufficient reason to think that it is a subjective approach; in fact, it may need to mention human beings in order to be objective.

The anthropic coincidences are widely claimed to provide evidence for intelligent creation in the universe. However, neither data northeory support this conclusion. No basis exists for assuming that a random universe would not have some kind of life. Calculations of the properties of universes having different physical constants than ours indicate that long-lived stars are not unusual, and thus most universes should have time for complex systems of some type to evolve. A multi-universe scenario is not ruled out, since (...) no known principle requires that only one universe exist. (shrink)

THE SAME PHILOSOPHICAL IDEAS often become the object of extremely diverse opinions. When Leibniz presented his idea of "possible worlds," Voltaire used the occasion for an ironic comment on "metaphysico-theologo-cosmology," whereas for P. L. M. de Maupertuis it was an idea that inspired his important discoveries in the domain of mathematical analysis of dynamic systems. Similar differences of opinion appear today in discussions on the so-called Anthropic Principle. Unequivalent variants of this principle state the existence of close links between (...) the appearance of carbon-based life and the cosmological structure of the universe, between the laws of cosmic evolution and values of physical constants. Many authors question the philosophical significance of the Anthropic Principle, regarding the principle as the product of arbitrary speculations. Their philosophical opponents try to show that certain versions of the principle, which do not go beyond generalization of empirical data, provide grounds for solid teleological assertions claiming that the appearance of the human observer is the goal of cosmic evolution.

In recent years, anthropic reasoning has been used to justify a number of controversial skeptical hypotheses. In this paper, we consider two prominent examples, viz. Bostrom’s ‘Simulation Argument’ and the problem of ‘Boltzmann Brains’ in big bang cosmology. We argue that these cases call into question the assumption, central to Bayesian confirmation theory, that the relation of evidential confirmation is universally symmetric. We go on to argue that the fact that these arguments appear to contradict this fundamental assumption should (...) not be taken as an immediate refutation, but should rather be seen as indicative of the peculiar role that the relevant hypotheses play in their respective epistemic frameworks.

Fr. Ernan McMullin wrote at least five essays in which anthropic reasoning in cosmology was a prominent topic of discussion and evaluation. Unlike thewritings of many passionate advocates and hostile critics of the so-called “anthropic principle” (AP), they are all nuanced essays—very much in keeping with Fr. Ernan’s usual approach to difficult and controversial subjects. Supporters of that approach will praise what he has to say as properly cautious and circumspect; others will likely find him often indecisive. In (...) this essay, I will indicate why, while I largely agree with the first group of readers, I am nevertheless sympathetic to the concerns of the latter group. (shrink)

Since Collins and Hawking described the need for an unimaginably precise flatness in the early universe, many have argued that the cosmos thereby requires design. This essay traces the developments of these design speculations from the Collins-Hawking discovery in 1973 to the present, and describes the four possible responses that are available to the apparent fine-tuning of the universe.

Why did Levinas choose Isaiah 45:7 ("I make peace and create evil: I the Lord do all that") as a superscription of his essay on evil? This article explores the role of evil in Levinas's religious ethics. The author discusses the structure of evil as revealed phenomenologically and juxtaposes it to the structure of subjectivity found in the writings of Levinas. The idea of the "ethical anthropic principle," modeled upon the cosmic anthropic principle, is then used to link (...) evil to the responsibility of the subject. The link is subsequently extended to God. This is proposed as one way of understanding the meaning of Isaiah 45:7. (shrink)

John Leslie presents a thought experiment to show that chances are sometimes observer-relative in a paradoxical way. The pivotal assumption in his argument – a version of the weak anthropic principle – is the same as the one used to get the disturbing Doomsday argument off the ground. I show that Leslie's thought experiment trades on the sense/reference ambiguity and is fallacious. I then describe a related case where chances are observer-relative in an interesting way. But not in a (...) paradoxical way. The result can be generalized: At least for a very wide range of cases, the weak anthropic principle does not giverise to paradoxical observer-relative chances. This finding could be taken to give new indirect support to the doomsday argument. (shrink)

This paper looks at Kurt Gödel's causally‐pathological cosmological models (derived from general relativity), in the light of anthropic explanations. If a Gödelian world is a possible world, could anthropic reasoning shed any light on whether or not our world is Gödelian? This paper argues that while there are some good anthropic reasons why our world ought to be Gödelian, too many observations suggest that our world can’t possibly be Gödelian in fact. If Gödel's world is a possible (...) one, anthropic teleology alone cannot explain why it isn’t the world we inhabit. Furthermore, if our world were Gödelian, anthropic arguments against the existence of extraterrestrial intelligences would imply a bleak human future. En route, some general objections to relativistic causal pathologies are addressed and some anthropic arguments to the effect that Gödelian worlds couldn’t sustain life are also addressed and dismissed.

The thesis, typical among dualists, that there are no necessitation relations between events of consciousness and physical events implies that it is prima facie lucky that in our world the apparently existing psychophysical laws usually match events of consciousness and physical events in a “harmonious” way. The lucky psychophysical laws argument concludes that typical dualism amounts to a psychophysical parallelism that is prima facie too improbable to be true. I argue that an anthropic reasoning in the space of possible (...) worlds makes the appearance of a harmonious match situation unsurprising, and that this is all that is needed for the argument to be harmless to a typical dualist.

This paper aims to justify the concept of natural intelligence in the biosemiotic context. I will argue that the process of life is (i) a cognitive/semiotic process and (ii) that organisms, from bacteria to animals, are cognitive or semiotic agents. To justify these arguments, the neural-type intelligence represented by the form of reasoning known as anthropic reasoning will be compared and contrasted with types of intelligence explicated by four disciplines of biology – relational biology, evolutionary epistemology, biosemiotics and the (...) systems view of life – not biased towards neural intelligence. The comparison will be achieved by asking questions related to the process of observation and the notion of true observers. To answer the questions I will rely on a range of established concepts including SETI (search for extraterrestrial intelligence), Fermi’s paradox, bacterial cognition, versions of the panspermia theory, as well as some newly introduced concepts including biocivilisations, cognitive/semiotic universes, and the cognitive/semiotic multiverse. The key point emerging from the answers is that the process of cognition/semiosis – the essence of natural intelligence – is a biological universal. (shrink)
