The physicist Richard Gott defends the Copernican principle, which claims that when we have no information about our position along a given dimension among a group of observers, we should consider ourselves to be randomly located among those observers in respect to that dimension. First, I apply Copernican reasoning to the distribution of evil in the universe. I then contend that evidence for intelligent extraterrestrial life strengthens four important versions of the argument from evil. I remain neutral (...) regarding whether this result is a reductio of these arguments from evil or the statement of a genuine evidential relationship. (shrink)

If we are to constrain our place in the world, two principles are often appealed to in science. According to the Copernican Principle, we do not occupy a privileged position within the Universe. The Cosmological Principle, on the other hand, says that our observations would roughly be the same, if we were located at any other place in the Universe. In our paper we analyze these principles from a logical and philosophical point of view. We show how (...) they are related, how they can be supported and what use is made of them. Our main results are: 1. There is a logical gap between both principles insofar as the Cosmological Principle is significantly stronger than the Copernican Principle. 2. A step that is often taken for establishing the Cosmological Principle on the base of the Copernican Principle and observations is not incontestable as it stands, but can be supplemented with a different argument. 3. The Cosmological Principle might be crucial for cosmology to the extent it is not supported by empirical evidence. (shrink)

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous (...) country. The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

There are two main paradigms for brain-related science, with different implications for brain-focused intervention or advancement. The paradigm of homeostasis (“stability through constancy,” Walter Cannon), originating from laboratory-based experimental physiology pioneered by Claude Bernard, shows that living systems tend to maintain system functionality in the direction of constancy (or similitude). The aim of physiology is elucidate the factors that maintain homeostasis, and therapeutics aim to correct abnormal factor functions. The homeostasis paradigm does not formally recognize influences outside its controlled experimental (...) frames and it is variable in its modelling of neural contributions. The paradigm of allostatic orchestration (PAO) extends the principle of allostasis (“stability through change”) as originally put forth by Peter Sterling. The PAO originates from an evolutionary perspective and recognizes that biological set points change in anticipation of changing environments. The brain is the organ of central command, orchestrating cross-system operations to support optimal behavior at the level of the whole organism. Alternative views of blood pressure regulation and posttraumatic stress disorder illustrate differences between the paradigms. For the PAO, complexities of top-down neural effects and environmental context are foundational (not to be “factored out”), and anticipatory regulation is the principle of their interface. The allostatic state represents the integrated totality of brain-body interactions. Health itself is an allostatic state of optimal anticipatory oscillation, hypothesized to relate to the state of criticality, a mathematical point of poise between phases, on the border between order and disorder (or the “edge of chaos”). Diseases are allostatic states of impaired anticipatory oscillations, demonstrated as rigidifications of set points across the brain and body (disease comorbidity). Conciliation of the paradigms is possible, with “reactive homeostasis” resolved as an illusion stemming from anticipation of environmental monotony. Considerations are presented with respect to implications of the two paradigms for brain-focused intervention or advancement; the hypothesis that the state of criticality is a vehicle for evolutionary processes; concordance with a philosophy of freedom based on ethical individualism as well as self-creativity, non-obsolescence, empowerment, and citizenship; and concluding reflections on the science and ethics of the placebo, and the potential for virtuous cycles of brain-Anthropocene interactions.

From the beginning of time, humans believed they were the center of the universe. Such important beings could be nowhere else than at the very epicenter of existence, with all the other things revolving around them. Was this an arrogant position? Only time will tell. What is certain is that as some people were so certain of their significance, aeons later some other people became too confident in their unimportance. In such a context, the Earth quickly lost its privileged position (...) at the center of the universe and along with this, the ideas of absolute motion and time became unbearable for the modern intellect, which saw nothing but relativeness in everything. After years of accepting the ideas of relativity at face value without doubting them, scientists are now mature enough to start questioning everything as any true scientist would do, including their own basic assumptions. And one would be surprised to see that the basic assumptions of today’s science in physics (and cosmology alike) are based on philosophically dogmatic beliefs that humans are nothing more than insignificant specks of dust. These specks cannot be in any privileged position in the cosmos, nor can their frames of reference. These specks cannot be living on a planet that is not moving while everything else is. There can be no hint of our importance whatsoever. Hence, the Copernican principle that has poisoned scientific thinking for aeons now. When one analyzes the evidence provided by science to support the idea of relativity though, he would see that the same evidence can more easily and simply fit into a model where the Earth stands still. Yet, scientists preferred to revamp all physics by introducing the totally unintuitive ides of relativity – including the absolute limit of the speed of light – than even admitting the possibility of humans having any notion of central position in the cosmos. True scientists though should examine all possible explanations, including those that do not fit their beliefs. To the dismay of so many modern scientists who blindly believe the validity of the theory of relativity at face value, the movement towards a true and honest post-modern science where all assumptions are questioned, necessarily passes through a place where the Earth we live in stands still. Non-relativistic explanations of the Michelson Morley experiment, related to a motionless Earth or to ether, are viable alternatives that deserve their place in modern scientific thought. (shrink)

This book offers a comprehensive critique of the Kantian principle that 'objects conform to our cognition' from the perspective of a Copernican world-view which stands diametrically opposed to Kant's because founded on the principle that our cognition conforms to objects. Concerning both Kant's ontological denial in respect of space and time and his equivalence thesis in respect of 'experience' and 'objectivity', Ryall argues that Kant's transcendental idealism signally fails to account for the one thing that is essential (...) for Copernicus and the only thing that would validate a comparison between his and Kant's critical philosophy, namely the subject as 'revolving object'. It is only by presupposing - in a transcendentally realistic sense - that human beings exist as physical things in themselves, therefore, that the 'observer motion' of Copernican theory is vindicated and the distorted nature of our empirical observations explained. In broadly accessible prose and by directly challenging the arguments of many stalwart defenders of Kant including Norman Kemp Smith, Henry E. Allison and Michael Friedman, Ryall's book will be of interest to both scholars and students of Kant's philosophy alike. (shrink)

The article analyzes the relationship between Kant's “Copernican revolution” and his theory of experience. The author demonstrates that the principles of the “altered way of thinking” form the foundation of the theory of experience and determine the structure and characteristics of transcendental cognition. The author explicates the structural elements of experience: sensible intuitions, pure a priori concepts of understanding, pure transcendental synthesis, schematism of pure concepts, principles as a system of rules for the use of categories, regulative ideas of (...) reason. All these elements are constitutive and regulative components of experience. In this case, Kant's theory of experience is the realistic constructivism. (shrink)

We develop an untyped framework for the multiverse of set theory.$\mathsf {ZF}$is extended with semantically motivated axioms utilizing the new symbols$\mathsf {Uni}(\mathcal {U})$and$\mathsf {Mod}(\mathcal {U, \sigma })$, expressing that$\mathcal {U}$is a universe and that$\sigma $is true in the universe$\mathcal {U}$, respectively. Here$\sigma $ranges over the augmented language, leading to liar-style phenomena that are analyzed. The framework is both compatible with a broad range of multiverse conceptions and suggests its own philosophically and semantically motivated multiverse principles. In particular, the framework is (...) closely linked with a deductive rule of Necessitation expressing that the multiverse theory can only prove statements that it also proves to hold in all universes. We argue that this may be philosophically thought of as aCopernican principlethat the background theory does not hold a privileged position over the theories of its internal universes. Our main mathematical result is a lemma encapsulating a technique for locally interpreting a wide variety of extensions of our basic framework in more familiar theories. We apply this to show, for a range of such semantically motivated extensions, that their consistency strength is at most slightly above that of the base theory$\mathsf {ZF}$, and thus not seriously limiting to the diversity of the set-theoretic multiverse. We end with case studies applying the framework to two multiverse conceptions of set theory: arithmetic absoluteness and Joel D. Hamkins’ multiverse theory. (shrink)

This is a highly original, wide-ranging, and unorthodox discourse on the idea of philosophy contained in Kant's major work, the Critique of Pure Reason. Bencivenga proposes a novel explanation of the Critique's celebrated "obscurity." This great obstacle to reading Kant, Bencivenga argues, has nothing to do with Kant's being a bad writer or with his having anything very complicated to say; rather, it is the natural result of the kind of operation Kant was performing: a universal conceptual revolution. Bencivenga contends (...) that in rejecting the traditional way of doing philosophy, Kant was proposing a paradigm shift comparable in magnitude to Copernicus's overthrow of the Ptolemaic view of the cosmos. Kant, however, was not successful in establishing his idea of philosophy as the new paradigm, and the old view persists in many contemporary versions. Bencivenga argues in favor of Kant's position, which he sees as entailing the view that the role of philosophy is to offer a plausible story about how objectivity might be grounded in certain principles of coherence of our mental states. This book is the story of Kant's revolutionary turnabout, what motivated it, and where it took him; it reveals Kant not only as a figure of historical importance, but as a source of ideas of great contemporary interest.

G. E. Moore’s early essay, “The Nature of Judgment,” makes common cause with F. H. Bradley’s Principles of Logic against British empiricism’s characteristic view of judgment. But primarily it attacks positions Bradley and the empiricists share. I develop a fuller analysis of both aspects of “The Nature of Judgment” than has appeared. Bradley’s rejection of empiricist nominalism, I argue, enables him to develop what Moore considers a superior account of judgment to empiricism’s. But positions carried over from empiricism require Bradley (...) to seek all judgments’ truth conditions in existing circumstances, a result intolerable to Moore, who views mathematical and ethical judgments as being true independently of the world. Moore abandons Bradley’s vestigal empiricism, arguing that it leads invariably to self-contradiction. I reconstruct this argument, and draw out of it an unrecognized tension between the anti-empiricist and the anti-idealist themes of Moore’s early writings. (shrink)

The previous chapter provided not only concrete evidence that Kant's System is based on the principle of perspective [II.2-3], but also a general outline of its perspectival structure [II.4].

This will be undertaken primarily in Parts Two and Three.

Consciousness is more important than the Higgs-Bosen particle. Consciousness has emerged as a term, and a problem, in modern science.

I say that consciousness points completely beyond present day science, to a whole new view of the universe, where consciousness, and (...) not matter or matter/energy is the true basis of the universe and the true fundamental term for the universe.

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.

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.

In Cosmos and Theos Professor Errol E. Harris develops the theological, ethical, and social implications of the Anthropic Cosmological Principle. He argues that the twentieth-century revolution in physics reinstates the traditional arguments for the existence of God that had been inevitably invalidated by the logic appropriate to Empiricism and the presuppositions of Newtonian science. Errol E. Harris stresses that the holism of contemporary science now demands a new dialectical logic and metaphysic, in the light of which old doctrines assume (...) a new aspect and gain fresh vitality. Professor Harris reviews the history of religion in relation to contemporary developments in science, contending that the conflict between the two, persistent since the seventeenth century, is largely the effect of the Copernican-Newtonian scientific paradigm rather than of any insuperable divergence of aim or dogma. He also reviews the salient arguments--and the criticism of them--that have been offered in the history of Western philosophy for God's existence. Cosmos and Theos concludes with a reinterpretation of Christian doctrine, intended to demonstrate the essential congruity between its tenets and the current conceptions of the Anthropic Principle.

This paper studies the different conceptions of both centrality and the principle or starting point of motion in the Universe held by Aristotle and later on by Copernicanism until Kepler and Bruno. According to Aristotle, the true centre of the Universe is the sphere of the fixed stars. This is also the starting point of motion. From this point of view, the diurnal motion is the fundamental one. Our analysis gives pride of place to De caelo II, 10, a (...) chapter of Aristotle’s text which curiously allows an ‘Alpetragian’ reading of the transmission of motion.In Copernicus and the Copernicans, natural centrality is identified with the geometrical centre and, therefore, the Sun is acknowledged as the body through which the Deity acts on the world and it also plays the role of the principle and starting point of cosmic motion. This motion, however, is no longer diurnal motion, but the annual periodical motion of the planets. Within this context, we pose the question of to what extent it is possible to think that, before Kepler, there is a tacit attribution of a dynamic or motive role to the Sun by Copernicus, Rheticus, and Digges.For Bruno, since the Universe is infinite and homogeneous and the relationship of the Deity with it is one of indifferent presence everywhere, the Universe has no absolute centre, for any point is a centre. By the same token, there is no place that enjoys the prerogative of being—as being the seat of God—the motionless principle and starting point of motion.Author Keywords: Author Keywords: Aristotle; Copernicus; Bruno; Centrality; Principle of movement; Extension of the Universe.

J. Richard Gott III (1993) has used the “Copernican principle” to derive a probability density function for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. John Leslie (1996) and others have used an apparently similar probabilistic argument, the “Doomsday Argument,” to claim that conventional predictions of longevity must be adjusted, based on Bayes’ Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of his (...) conclusions—his delta t formula—is mathematically equivalent to Laplace’s famous (and notorious) ‘rule of succession’; moreover, Gott’s delta t formula is a plausible worst-case (if one favors greater longevity) bound in some contexts. On the other hand, the Doomsday Argument is fallacious: the argument’s Bayesian formalism is stated in terms of total duration, but all attempted real-life applications of the argument—with one exception, an application by Gott 1994—actually plug in prior probabilities for future duration; moreover, the Self-Sampling Assumption, an essential premise of the Doomsday Argument, is contradicted by the prior information in all known real-life cases. But rejecting the Doomsday Argument does not entail rejecting the possibility of learning about the future from the past. Applying the work of Bruce M. Hill (1968, 1988, 1993) and Frank P.A. Coolen (1998, 2006) in the field of non-parametric predictive inference, I propose and defend an alternative methodology for quantifying how past longevity of any phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. This methodology forms the basis of a calculus of induction. (shrink)

According to QBism, quantum states, unitary evolutions, and measurement operators are all understood as personal judgments of the agent using the formalism. Meanwhile, quantum measurement outcomes are understood as the personal experiences of the same agent. Wigner’s conundrum of the friend, in which two agents ostensibly have different accounts of whether or not there is a measurement outcome, thus poses no paradox for QBism. Indeed the resolution of Wigner’s original thought experiment was central to the development of QBist thinking. The (...) focus of this paper concerns two very instructive modifications to Wigner’s puzzle: One, a recent no-go theorem by Frauchiger and Renner, and the other a thought experiment by Baumann and Brukner. We show that the paradoxical features emphasized in these works disappear once both friend and Wigner are understood as agents on an equal footing with regard to their individual uses of quantum theory. Wigner’s action on his friend then becomes, from the friend’s perspective, an action the friend takes on Wigner. Our analysis rests on a kind of quantum Copernican principle: When two agents take actions on each other, each agent has a dual role as a physical system for the other agent. No user of quantum theory is more privileged than any other. In contrast to the sentiment of Wigner’s original paper, neither agent should be considered as in “suspended animation.” In this light, QBism brings an entirely new perspective to understanding Wigner’s friend thought experiments.

Cosmology raises novel philosophical questions regarding the use of probabilities in inference. This work aims at identifying and assessing lines of arguments and problematic principles in probabilistic reasoning in cosmology. -/- The first, second, and third papers deal with the intersection of two distinct problems: accounting for selection effects, and representing ignorance or indifference in probabilistic inferences. These two problems meet in the cosmology literature when anthropic considerations are used to predict cosmological parameters by conditionalizing the distribution of, e.g., the (...) cosmological constant on the number of observers it allows for. However, uniform probability distributions usually appealed to in such arguments are an inadequate representation of indifference, and lead to unfounded predictions. It has been argued that this inability to represent ignorance is a fundamental flaw of any inductive framework using additive measures. In the first paper, I examine how imprecise probabilities fare as an inductive framework and avoid such unwarranted inferences. In the second paper, I detail how this framework allows us to successfully avoid the conclusions of Doomsday arguments in a way no Bayesian approach that represents credal states by single credence functions could. -/- There are in the cosmology literature several kinds of arguments referring to self- locating uncertainty. In the multiverse framework, different "pocket-universes" may have different fundamental physical parameters. We don’t know if we are typical observers and if we can safely assume that the physical laws we draw from our observations hold elsewhere. The third paper examines the validity of the appeal to the "Sleeping Beauty problem" and assesses the nature and role of typicality assumptions often endorsed to handle such questions. -/- A more general issue for the use of probabilities in cosmology concerns the inadequacy of Bayesian and statistical model selection criteria in the absence of well-motivated measures for different cosmological models. The criteria for model selection commonly used tend to focus on optimizing the number of free parameters, but they can select physically implausible models. The fourth paper examines the possibility for Bayesian model selection to circumvent the lack of well-motivated priors. (shrink)

Like the Copernican revolution which initiated the Modern project, there has been a thermodynamic revolution in the empirical sciences in the last two centuries. The aim of this paper is to show how we might draw from this revolution to make new and startling metaphysical and ethical claims concerning the nature and value of reality. To this end, this paper employs Aristotle’s account of the relation of the various philosophies and sciences to one another to show how we might (...) assert a new theory of being, moral value, and practical action from the primacy of entropic decay asserted in the contemporary mathematical sciences. This paper proceeds to show how, from what the contemporary sciences have concluded concerning the primacy of entropic decay within reality, unbecoming might be forwarded as a new account of the essence of existence: i.e., the first cause and motivating principle of reality’s formal, material, efficient, and final nature. The paper concludes by arguing that a new and surprising account of universal ethical value and normative duty can be deduced from such a metaphysics of decay. (shrink)

Kant's 'Copernican Revolution', which began in the Critique of Pure Reason (1781/1787), had, by the early 1790s, fundamentally altered the terrain of German philosophy – but not entirely in the way that Kant had foreseen. Skeptical challenges to Kant's discursive account of cognition, in which experience arises from the separate faculties of sensibility and understanding, had led thinkers such as K.L. Reinhold and J.G. Fichte to attempt to provide a first, foundational principle for the critical philosophy. These efforts (...) were enormously influential, but by the middle of the 1790s, they too were facing a great deal of critical scrutiny. The central challenge to the Fichtean project came from an unlikely quarter: a group of young thinkers and poets who are collectively known as the early Romantics. For the Romantics, Fichte's project remains too 'subjectivist', for it tries to provide an account of the world by beginning with the conditions that govern subjectivity alone. Rather, the Romantics argue that the world must be understood in terms of a monistic Absolute, akin to Spinoza's substance, in which all dualisms are overcome. It is with this step that Absolute Idealism comes on the scene, and sets the stage for the development of Hegel's system in the early 1800s. This essay, which continues the story of 'Who's Who from Kant to Hegel I', examines the ways in which early Romanticism reacted to the Fichtean project, looks at a variety of anti-foundationalist idealisms that the Romantics – in particular Hölderlin, Novalis, Schlegel, and Schleiermacher – developed, and traces the role that Friedrich Schelling plays in offering the first systematic account of Absolute Idealism.

I confront Feyerabend's position and critical rationalism in order to have a foundation or starting point for my (historical) investigation. The main difference of his position towards falsificationism is the belief that different theories cannot be discussed rationally. Feyerabend is convinced that Galilei's observations with the telescope in the historical context of the Copernican revolution supports his criticism. In particular, he argues that the Copernican theory was supported by deficient hypotheses, and falsifications were disposed by ad hoc hypotheses (...) and propaganda. Furthermore, he claims that his philosophy of science reconstructs Galilei's defence of the Copernican theory. He introduces a central principle of his position (the principle of tenacity) in order to justify a research strategy of not eliminating falsified theories. He tries to show that the tenacious defence of a theory corresponds to Galilei's defence of the Copernican theory. Remarkably, Feyerabend's approach to explain the development of science earns an important support from his interpretation of Galilei's observations. On this basis I give a falsificationist interpretation of Galilei's observations with the telescope, and oppose this interpretation to Feyerabend's. From a falsificationist perspective, auxiliary hypotheses compete during the Copernican revolution which can (with some effort) be critically discussed. Then I analyse the historical case in order to test Feyerabend's interpretation of the Copernican revolution. Inter alias I investigate thoroughly whether Galilei, as Feyerabend claims, immunised falsifications of the Copernican theory by the introduction of ad hoc hypotheses. The investigation considers Galilei's explanation of Venus' phases, his establishment of the irradiation hypothesis, the explanation of the telescope's functionality, and the role of the reproducibility of the observations with the telescope. Finally I provide a rational reconstruction of Galilei's falsification of the Ptolemaic theory. The formalisation shows that Galilei was not a cautious critical rationalist, but a very confident scientist using the method of falsification. (shrink)

The present work is an attempt to critically analyse different philosophical concepts and theories associated with Husserlian phenomenology Western philosophy has witnessed series of revolutions beginning from Socratic-Platonic tradition to Cartesian and Kantian revolution. The conceptual revolution does not terminate over here rather it is more prominently manifested in Husserl's philosophy. The originality of the author lies in interpreting Husserl's phenomenology as second Copernican revolution Phenomenology is an attempt to locate the principle of objectivity in the element of (...) subjectivity. It developed as a reaction to the trends of naturalism and historicism. It is further analysed how Cartesian, Humean and Kantian philosophy have provided intellectual stimulus to fertile Husserlian mind to develop grand phenomenology which has revolutionary impact over subsequent philosophies like existential phenomenology, hermeneutics and deconstruction. The brilliant attempt is made to compare Husserl's account of 'eide' with 'denizens' of Quantum mechanism leading to the conclusion that the holistic view of Husserl and Quantum physics maintains the correlativity of 'subject' and 'object'. The author has presented his work with conceptual clarity, lucid expression, systematic presentation and critical exposition of the subject matter in such a manner that the ponderous writing of Husserl with the assistance of this book can be easily assimilated by student community but academic standard is not at all compromised as he has consulted numerous journals, original texts, standard commentaries and recent arrivals on Husserl to make it authentic and relevant. It is a valuable and powerful contribution to contemporary thought which will evoke an enthusiastic response from the scholars and students of Philosophy. -/- Content of the Book includes -/- Chapter-l Introduction, Chapter-II Nature of Kant's Copernican Revolution, Chapter-III Nature of Husserl's Second Copernican Revolution, Chapter-IV The Central Themes of Phenomenology, Chapter-V Transcendental Idealism of Kant and Husserl, Chapter-VI A Concluding Postscript, -/- This work is Peer reviewed in JICPR, volume XXIII, No. 3, July- September, 2006 by Prof. Archana Barua, Department of Humanities & Social Sciences, IIT, Guwhati. 2.

Early in the Preface to Religion within the Limits of Reason Alone, Kant claims that “morality leads ineluctably to religion”. This thesis is hardly an innovation of the Religion. Again and again throughout the critical corpus, Kant argues that religious belief is ethically significant, that it makes a morally meaningful difference whether an agent believes or disbelieves. And yet these claims are surely among the most doubted of Kant's positions – and they are often especially doubted by readers who consider (...) themselves Kantians. That Kant of all people should have so cherished religion is perhaps surprising: his moral view enshrines the notion that moral worth arises solely form the “good will”, that is, from a will determined by the moral law. Kant claims to be able to deduce this law and to account for how it motivates without ever relying on religious propositions. Rather, he grounds morality in the conception of autonomy, in the absolutely free self-legislation of the moral principle. So why, after effecting this dramatic Copernican revolution in ethics, does Kant appear to backslide, insisting on the moral necessity of religious belief? (shrink)

Most philosophers of religion subscribe to some variety of religious realism: they believe that religious statements aim at capturing a mind-independent reality and are true precisely if they successfully do so. Curiously, most religious realists also believe that at least some of our religious beliefs are rationally justified. In this paper, I argue that these positions are actually at odds with each other. Religious realists should rather be religious skeptics. I first argue that realism always implies the possibility of our (...) beliefs being false. Then, I develop a Copernican argument to show that we have no reason to believe that we are in an epistemically privileged position where we could be confident that our particular belief is justified while all competing beliefs are not. This seems impossible for two reasons: (a) From a probabilistic point of view (adopting a principle of mediocrity), it is highly unlikely that current humans have the maximum of epistemic capacities possible. Rather, our ability to understand reality is limited, so we should expect at least some parts of religious reality to remain unknown to us. (b) From a deep-time perspective, humanity has not pondered religious questions for long. We are probably still in the early stages of our cognitive evolution, and so we should treat our religious beliefs as provisional and open to revision. (shrink)

Schleiermacher's Copernican revolution in theology is effected through his presentation of the Christian mythos in terms of a phenomenological anthropology of self-consciousness. Moreover, as Niebuhr shows in this apt study of some features of Schleiermacher's theological thinking, the principles which determine the shape of that revolution can be deduced neither from a biblical dogmatics allegedly purified of philosophical presuppositions nor from a philosophy uninformed by theological experience. In the first part of the book, Niebuhr discusses Schleiermacher's little-known work The (...) Christmas Eve: A Dialogue, affording us a picture of the author's starting-point in the experience of a salvation or potentiated self-consciousness which is historically and socially mediated. The subsequent analysis of the lectures on hermeneutics and ethics discloses the object of Schleiermacher's inquiry to be not the supernatural being that posits the cosmos, but the creative Logos indwelling the individual and all men by means of the common, organic media of human existence in which the self both comes to be and comes to create history and culture. Finally, The Christian Faith is reviewed by Niebuhr in terms of the expression it gives to the mature Schleiermacher's theology and christology. The primordial consciousness of being-in-relation reveals the historical, societal, worldly context of the self and the various polarities of the self's existence such that religion emerges as a phenomenon coterminous with man's affective response to the relationships in which the whole of human nature is bound, and theology, the "daughter of religion," becomes the methodology by which the articulation of an affective determination of self-consciousness is achieved. The rigorously pursued explicitation [[sic]] of the forms and determinations of self-consciousness is interpreted by Niebuhr with a penetration and a sympathy at once acute and comprehensive. By giving us a series of insights into Schleiermacher's "thinking in motion," Niebuhr has contributed a cogent testimony to the nineteenth-century theologian's central importance in the fields of hermeneutical theory, philosophical ethics, philosophy of religion and culture, and theology. One would have welcomed a more critical appraisal of Schleiermacher's view of the formal and material compatibility of philosophy and theology, understanding and feeling, inasmuch as the scope of theological inquiry appears to be limited by the boundaries of reason set forth in the ethics, and philosophical anthropology is apparently reduced to a rather sophisticated phenomenology of religious experience. In any case, Niebuhr's scholarly treatment of the material should lead the reader to an informed examination of Schleiermacher's text.--J. M. S. (shrink)

Summary Descartes' two treatises of corpuscular-mechanical natural philosophy—Le Monde (1633) and the Principia philosophiae (1644/1647)—differ in many respects. Some historians of science have studied their significantly different theories of matter and elements. Others have routinely noted that the Principia cites much evidence regarding magnetism, sunspots, novae and variable stars which is absent from Le Monde. We argue that far from being unrelated or even opposed intellectual practices inside the Principles, Descartes' moves in matter and element theory and his adoption of (...) wide swathes of novel matters of fact, were two sides of the same coin—that coin being his strategies for improving the systematic power, scope and consistency of the natural philosophy presented in the Principia. We find that Descartes' systematising strategy centred upon weaving ranges of novel matters of fact into explanatory and descriptive narratives with cosmic sweep and radical realist Copernican intent. Gambits of this type have recently been labelled as ‘cosmographical’ (the natural philosophical relating of heavens and earth in contemporary usage). Realist Copernican natural philosophers, from Copernicus himself, through Bruno, Gilbert and Galileo did this to varying degrees; but, we suggest, Descartes presented in Books III and IV of the Principia the most elaborate and strategically planned version of it, underneath the ostensible textbook style of the work.

Perhaps the ultimate significance of Kant's Copernican revolution in philosophy lies in its attempted reconciliation of the transcendental, logical orientation of continental rationalism with the humanistic, psychological approach of British empiricism. With the rationalists, Kant distinguished sharply between questions concerning the causes and origins of our knowledge and questions about its limits and objective validity. Thus, a rigorous critique of psychologism, i.e. of any attempt to explain, or explain away the validity of either our cognitive or moral principles by (...) means of an analysis of their basis in human nature or their genesis in human experience, is one of the most characteristic traits of the Kantian philosophy. Yet this transcendental, logical investigation of the nature and limits of knowledge, and of the fundamental principles of morality leads Kant back to the human subject, in whose cognitive faculties he finds the a priori principles of human knowledge and in whose autonomy he finds the basis of the categorical imperative. This gives rise to a paradoxical conception of man as on the one hand, together with the rest of creation, a part of nature, subject to its laws, and on the other hand, in his capacity as knower and actor, a rational being who not only transcends nature in the sense that he is not completely determined by its laws, but who is actually the author of these laws.

The consensus view in the literature is that, according to Kant, definitions in philosophy are impossible. While this is true prior to the advent of transcendental philosophy, I argue that with Kant's Copernican Turn definitions of some philosophical concepts, the categories, become possible. Along the way I discuss issues like why Kant introduces the ‘Analytic of Concepts’ as an analysis of the understanding, how this faculty, as the faculty for judging, provides the principle for the complete exhibition of (...) the categories, how the pure categories relate to the schematized categories, and how the latter can be used on empirical objects.
