The design argument for God’s existence was critically assessed when in the growth of modern science the cognitive value of teleological categories was called into question. In recent discussions dealing with anthropic principles there has appeared a new version of the design argument, in which cosmic design is described without the use of teleological terms. The weak anthropic principle (WAP), a most critical version of all these principles, describes the fine-tuning of physical parameters necessary to the (...) genesis of carbon-based life. Consequently, a new version of the philosophical design argument can be developed on the basis of the weak anthropic principle.(edited). (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)

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 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.

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.

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)

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 (...) class='Hi'>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)

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)

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)

Complexity and life as we know it depend crucially on the laws and constants of nature as well as the boundary conditions, which seem at least partly “fine-tuned.” That deserves an explanation: Why are they the way they are? This essay discusses and systematizes the main options for answering these foundational questions. Fine-tuning might just be an illusion, or a result of irreducible chance, or nonexistent because nature could not have been otherwise (which might be shown within a fundamental theory (...) if some constants or laws could be reduced to boundary conditions or boundary conditions to laws), or it might be a product of selection: either observational selection (weak anthropic principle) within a vast multiverse of many different realizations of physical parameters, or a kind of cosmological natural selection making the measured parameter values quite likely within a multiverse of many different values, or even a teleological or intentional selection or a coevolutionary development, depending on a more or less goal-directed participatory contribution of life and intelligence. In contrast to observational selection, which is not predictive, an observer-independent selection mechanism must generate unequal reproduction rates of universes, a peaked probability distribution, or another kind of differential frequency, resulting in a stronger explanatory power. The hypothesis of Cosmological Artificial Selection (CAS) even suggests that our universe may be a vast computer simulation or could have been created and transcended by one. If so, this would be a far-reaching answer – within a naturalistic framework! – of fundamental questions such as: Why did the big bang and fine-tunings occur, what is the role of intelligence in the universe, and how can it escape cosmic doomsday? This essay critically discusses some of the premises and implications of CAS and related problems, both with the proposal itself and its possible physical realization: Does CAS deserve to be considered as a convincing explanation of cosmic fine-tuning? Is life incidental, or does CAS revalue it? And are life and intelligence ultimately doomed, or might CAS rescue them? (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.

The construction of space-time in a physical system without time and dynamics is considered. It is shown that the anthropic principle and causality principle inevitably arise in models without time and dynamics.

It is shown that, in principle, there is the possibility of experimental (...) verification of what is true - realism or idealism. (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.

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)

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)

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 (...) 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.

Carter’s anthropic principle reminds us that intelligent life can find itself only in life-permitting times, places or universes. The principle concerns a possible observational selection effect, not a designing deity. It has no special concern with humans, nor does it say that intelligent life is inevitable and common. Barrow and Tipler, who discuss all this, are not biologically ignorant. As argued in "Universes" (Leslie, 1989) they may well be right in thinking that "fine tuning" of force strengths (...) and particle masses, without which life would be impossible, proves the reality of God or else of multiple universes plus observational selection.

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.

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)

A significant criticism of the anthropic principle as a scientific claim is that testable predictions cannot be derived from it. Brandon Carter has argued, however, that the principle can be used to predict on the one hand that the period of time biological evolution is intrinsically likely to require is very large, and on the other that the number of ‘critical steps’ that have occurred in the evolution of life on earth is related to the length of (...) time life can continue to evolve. I attempt to show that neither of Carter's arguments provides a convincing defence of the testability of the anthropic principle. (shrink)

Recently, different versions of a cosmological “anthropic principle” have been used to try to explain various features of the universe. This essay, which focuses on some early uses of AP, argues that even modest appeals to it cannot be regarded as genuinely explanatory.

In the absence of a fundamental theory that precisely predicts values for observable parameters, anthropic reasoning attempts to constrain probability distributions over those parameters in order to facilitate the extraction of testable predictions. The utility of this approach has been vigorously debated of late, particularly in light of theories that claim we live in a multiverse, where parameters may take differing values in regions lying outside our observable horizon. Within this cosmological framework, we investigate the efficacy of top-down (...) class='Hi'>anthropic reasoning based on the weak anthropic principle. We argue contrary to recent claims that it is not clear one can either dispense with notions of typicality altogether or presume typicality, in comparing resulting probability distributions with observations. We show in a concrete, top-down setting related to dark matter, that assumptions about typicality can dramatically affect predictions, thereby providing a guide to how errors in reasoning regarding typicality translate to errors in the assessment of predictive power. We conjecture that this dependence on typicality is an integral feature of anthropic reasoning in broader cosmological contexts, and argue in favour of the explicit inclusion of measures of typicality in schemes invoking anthropic reasoning, with a view to extracting predictions from multiverse scenarios.

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 society of the information is based on the ability of humans to communicate in real time. This is possible thanks to the emission of electromagnetic waves. In this work it is discussed, by analyzing the round trip time parameter, if it is possible to expand the society of the information out of the Earth. The results show that the value of the speed of light limits this expansion. Real time applications, such as videogaming, remote surgery, or voice conversations, are (...) only possible on Earth and its proximities, which indicates that there could be a relation between real time telecommunications on Earth and the anthropic principle.

The purpose of this paper is to analyze the theoretical commitments of autopoietic enactivism in relation to Errol E Harris’s dialectical holism in the interest of establishing a common metaphysical ground. This will be undertaken in three stages. First, it is argued that Harris’s reasoning provides a means of developing enactivist ontology beyond discussions limited to cognitive science and into domains of metaphysics that have traditionally been avoided by phenomenologists. Here, I maintain enactivist commitments are consistent with Harris’s reasoning from (...) certain synthetic a priori first principles, to his derivation of a teleological anthropic principle, which asserts the necessity of consciousness within the cosmos. Second, it is proposed that Steven Rosen’s long-standing proposal for a topology of phenomenology may provide a common logical foundation for both Harris and enactivists regarding anthropic reasoning. Third, it is argued that a pragmatic approach to process ontology is the most rigorous way of responding to the realism/anti-realism concerns that inevitably follow. If successful, this work will update Harris’s arguments with contemporary scientific and philosophical terminology and extend enactivism from philosophy of mind, into a general phenomenological ontology.

The Anthropic Principle, in use by physicists, astronomers, and cosmologists, is currently under consideration by philosophers. This principle, in its various forms, appeals to man's existence as a constraint on our determination of natural laws and natural constants, as a principle of prediction, and, in its strongest form, as a principle of explanation which sanctions an argument for the universe being a product of design. What I shall endeavour to show here is how this (...) class='Hi'>principle, in its various forms, is used in furthering our understanding of cosmology, and why this principle cannot be used as a principle of explanation.

I argue in the essay that the fourteenth-century logicians William Heytesbury and Albert of Saxony developed an argument I call the Socrates-Minus Argument. Their analysis and rejection of it indicates a direction towards a pragmatic resolution to the contemporary Descartes-Minus Argument. Their resolution is similar to the view adopted today by Peter van Inwagen, namely, that “arbitrary undetached parts of physical objects,” like 'all of Socrates except his finger' simply do not exist. I conclude the fourteenth-century approach does not run (...) afoul of Leibniz's law of the Indiscernibility of Identicals, but utilizes a form of Leibniz's Identity of Indiscernibles that, when combined with a weak “anthropic principle,” yield a pragmatic resolution to the Descartes-Minus Argument.

We give a level-by-level analysis of the Weak Vopěnka Principle for definable classes of relational structures ( $\mathrm {WVP}$ ), in accordance with the complexity of their definition, and we determine the large-cardinal strength of each level. Thus, in particular, we show that $\mathrm {WVP}$ for $\Sigma _2$ -definable classes is equivalent to the existence of a strong cardinal. The main theorem (Theorem 5.11) shows, more generally, that $\mathrm {WVP}$ for $\Sigma _n$ -definable classes is equivalent to the (...) existence of a $\Sigma _n$ -strong cardinal (Definition 5.1). Hence, $\mathrm {WVP}$ is equivalent to the existence of a $\Sigma _n$ -strong cardinal for all $n<\omega $. (shrink)

We study the extension 123) of the theory S21 by instances of the dual weak pigeonhole principle for p-time functions, dWPHPx2x. We propose a natural framework for formalization of randomized algorithms in bounded arithmetic, and use it to provide a strengthening of Wilkie's witnessing theorem for S21+dWPHP. We construct a propositional proof system WF , which captures the Π1b-consequences of S21+dWPHP. We also show that WF p-simulates the Unstructured Extended Nullstellensatz proof system of Buss et al. 256). We (...) prove that dWPHP is equivalent to a statement asserting the existence of a family of Boolean functions with exponential circuit complexity. Building on this result, we formalize the Nisan–Wigderson construction in a conservative extension of S21+dWPHP. (shrink)

Barrow and Tipler’s contention that the Anthropic Principle is obviously true and removes the need for an explanation of fine-tuning fails because the Principle is trivially true, and only within the context of a World Ensemble, whose existence is not obvious, does a selection effect become significant. Their objections to divine design as an explanation of fine-tuning are seen to be misconceived.

The fundamental constants and initial conditions of the universe seem "finely tuned" for human habitation. The anthropic principle attempts to explain this fine tuning in terms of the eventual development of intelligent life. A closer look at the principle’s explanandum, however, reveals that it is teleologically and anthropocentrically biased. Our ignorance of the physical requirements of nonhuman forms of life forces the principle to be more unjustifiably anthropocentric and more speculative than is commonly admitted. Leslie’s, Barrow’s (...) and Tipler’s attempts to avoid an overly anthropocentric anthropic principle fail to solve these problems. (shrink)

It is well known that S12 cannot prove the injective weak pigeonhole principle for polynomial time functions unless RSA is insecure. In this note we investigate the provability of the surjective weak pigeonhole principle in S12 for provably weaker function classes.

Recently Díaz, Hössjer and Marks (DHM) presented a Bayesian framework to measure cosmological tuning (either fine or coarse) that uses maximum entropy (maxent) distributions on unbounded sample spaces as priors for the parameters of the physical models (https://doi.org/10.1088/1475-7516/2021/07/020). The DHM framework stands in contrast to previous attempts to measure tuning that rely on a uniform prior assumption. However, since the parameters of the models often take values in spaces of infinite size, the uniformity assumption is unwarranted. This is known as (...) the normalization problem. In this paper we explain why and how the DHM framework not only evades the normalization problem but also circumvents other objections to the tuning measurement like the so called weak anthropic principle, the selection of a single maxent distribution and, importantly, the lack of invariance of maxent distributions with respect to data transformations. We also propose to treat fine-tuning as an emergence problem to avoid infinite loops in the prior distribution of hyperparameters (common to all Bayesian analysis), and explain that previous attempts to measure tuning using uniform priors are particular cases of the DHM framework. Finally, we prove a theorem, explaining when tuning is fine or coarse for different families of distributions. The theorem is summarized in a table for ease of reference, and the tuning of three physical parameters is analyzed using the conclusions of the theorem. (shrink)
