Lithopanspermia is a theory proposing a natural exchange of organisms between solar system bodies as a result of asteroidal or cometary impactors. Research has examined not only the physics of the stages themselves but also the survival probabilities for life in each stage. However, although life is the primary factor of interest in lithopanspermia, this life is mainly treated as a passive cargo. Life, however, does not merely passively receive an onslaught of stress from surroundings; instead, it reacts. Thus, planetary (...) ejection, interplanetary transport, and planetary entry are only the first three factors in the equation. The other factors are the quality, quantity, and evolutionary strategy of the transported organisms. Thus, a reduction in organism quantity in stage 1 might increase organism quality towards a second stress challenge in stage 3. Thus, robustness towards a stressor might in fact be higher in the bacterial population surviving after transport in stage 3 than at the beginning in stage 1. Therefore, the stages of lithopanspermia can themselves facilitate evolutionary processes that enhance the ability of the collected organisms to survive stresses such as pressure and heat shock. Thus, the multiple abiotic pressures that the population encounters through the three stages can potentially lead to very robust bacteria with survival capacities considerably higher than might otherwise be expected. This analysis details an outcome that is possible but probably rare. However, in addition to lithopanspermia, spacecraft mediated panspermia may also exist. The analogous stages in a spacecraft would result in a greater likelihood of increasing the stress tolerance of hitchhiking organisms. Furthermore, missions seeking life elsewhere will frequently be sent to places where the possibility of life as we know it is assumed to exist. Thus, we not only can transport terrestrial organisms to places where they are potentially more likely to survive but also may increase their invasive potential along the way. This analysis highlights further requirements that planetary protection protocols must implement and also provides a framework for analyses of ecological scenarios regarding the transmission of life, natural or artificial, between worlds in a solar system.

It is often assumed that the transition between chemical evolution and biological evolution undergoes a smooth process; that once life has arisen, it will automatically ‘flood’ a solar system body. However, there is no a priori reason to assume that a link between them is a given. The fact that both chemical evolution and biological evolution meet in a single point can be critical. Thus, one may ask: can a world’s environment be favourable for chemical evolution but not for biological (...) evolution, or vice versa? This is an important question worth exploration because certain worlds in the solar system in the past seemed to possess the possibility of chemical evolution, while several worlds in the present seem to exhibit such a possibility. Have such solar system bodies thus been, or are, ‘flooded’ by life? Did they possess the opportunity for biological evolution? The answer depends on the very nature of certain conditions under which evolution occurs, which may indicate that a link between chemical evolution and biological evolution is not automatically realised on a habitable solar system body. Thus, these conditions imply that in the emergence and distribution of cellular life, there exists an indeterminacy bottleneck at which chemical evolution and biological evolution meet through a single cell, whose descendants goes ‘information explosive’, ‘entropy implosive’ and ‘habitat expansive’, which determine whether life moves on to new environments. The consequence is that a world's environment can indeed be favourable for biological evolution, but not for chemical evolution. Thus, even if chemical evolution leads to the emergence of a microbial organism in a world, then it is not a given that such a first life form will be subjected to distribution to other environments; and not a given that its existence will continue in the environment it originated in. Thus, the bottleneck may be one of the decisive factors in the differences between habitable and inhabited worlds. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

Until quite recently, mind-body dualism has been regarded with deep suspicion by both philosophers and scientists. This has largely been due to the widespread identification of dualism in general with one particular version of it: the interactionist substance dualism of Réné Descartes. This traditional form of dualism has, ever since its first formulation in the seventeenth century, attracted numerous philosophical objections and is now almost universally rejected in scientific circles as empirically inadequate. During the last few years, however, renewed attention (...) has begun to be paid to the dualistic point of view, as a result of increasing discontent with the prevailing materialism and reductionism of contemporary scientific and philosophical thought. Awareness has grown that dualism need not be restricted to its traditional form and that other varieties of dualism are not subject to the difficulties commonly raised against Descartes' own version of it. -/- Interest in these alternative versions of dualism is growing fast today, because it seems that they are capable of capturing deep-seated philosophical intuitions, while also being fully consistent with the methodological assumptions and empirical findings of modern scientific work on the human mind and brain. The object of this book is to provide philosophers, scientists, their students, and the wider general public with an up-to-date overview of current developments in dualistic conceptions of the mind in contemporary philosophy and science.

Summary Is it possible to discover the critical realist foundations of Gestalt theory in Berlin comparative musicology (vergleichende Kunstwissenschaft) associated above all with Erich M. von Hornbostel? The balance of natural science explanation and phenomenal experience is a useful model for overcoming Eurocentrism in comparative ethnomusicology, relying both on third-person tools and indigenous music systems. This paper uses Gestalt critical realist epistemology and methodology and a portrayal of the strata making up the understanding of a musical act with chemico-physical, phenomenal (...) and cultural components to create an “amphibian” ethnomusicology. Using this framework it is possible to understand Hornbostel and Sachs’ musical instrument classification system and Hornbostel’s account of “primitive” music as strata in a Gestalt explanatory system. The potential binding agent through the strata is isomorphism. (shrink)

C. I. Lewis intended his systems S1–S5 as contributions to the study of “strict implication”, but in his formulation, strict implication is so thoroughly intertwined with other notions, such as possibility and negation, that it remains a problem, to separate out the properties of strict implication itself. I shall solve this problem for S2–5 and von Wright's M. The results for S3–5 are given below, while the implicative parts of S2 and M, which are rather more complicated, are given in (...) §5.In this presentation, ‘⊃’ stands for strict implication, and missing brackets for ‘⊃’ are restored by associationtothe right. Astrictformula is one of the form A ⊃ B. Axiom schemes are used throughout. (shrink)

Hans Jonas’ Vortrag von 1963 über seine Lehrer Edmund Husserl und Martin Heidegger erhebt keinen wissenschaftlichen Anspruch; er ist vielmehr als Geschichte zweier Philosophen und ihrer Beziehung zueinander konzipiert. Jonas thematisiert auch den Zerfall dieser Beziehung sowie grundsätzlich die Herausforderungen in Bezug auf die Möglichkeit zu philosophieren. Im Gegensatz zu seinen anderen Texten über Husserl scheut sich Jonas in diesem Vortrag nicht, Kritik an seinem ehemaligen Lehrer zu üben.

In Lars von Trier’s Breaking the Waves, the protagonist Bess McNeill is often viewed as a Christ-figure, in particular, as an image of Christ’s love. In this essay, I address the feminist critique that taking Bess in this way represents a serious distortion of Christ's love, arguing that Bess need not be seen as endorsing a self-destructive and victimizing form of love that feminist critics rightly reject. Instead, I suggest that we can view her love as an indictment of the (...) institutions structuring its expression. Finally, I argue that Bess’s love for Jan combines aspects of love that have typically been segregated into eros and agape in a way that enriches our understanding of agape and prompts us in turn to re-evaluate our understanding of Christ’s love and death.

This is the first English translation of the majority of Fichte’s 1807 essay on Machiavelli, which has been hailed as a masterpiece and was important for the development of German idealist political thought, as well as for its reception by figures such as Carl von Clausewitz, Max Weber, Leo Strauss, and Carl Schmitt. Fichte’s essay attempts to resuscitate Machiavelli as a legitimate political thinker and an “honest, reasonable, and meritorious man.” It tacitly critiques Napoleon, who was occupying Prussia when Fichte (...) composed the piece, and calls on the Germans to resist the French. And some have argued that it marks a shift in Fichte’s political thought toward a more realist position. (shrink)

Der Kunsthistoriker Ernst Hans Josef Gombrich hat einen „wissenschaftlichen“ oder kognitiven Ansatz zur Erforschung der Geschichte und Psychologie der Künste entwickelt, der sehr maßgeblich von der Wissenschaftstheorie seines engen Freundes Karl Popper beeinflusst worden ist. Die geistige Nähe zwischen beiden wird in Gombrichs zentraler Arbeit zur Wiederentdeckung der Repräsentation in der Renaissance und zur Historiografie der Kunst deutlich. Ihre Differenzen verdienen allerdings ebenfalls Beachtung. Gombrichs Ansicht zufolge verändern sich Geschmack und Stil entsprechend der von ihm so genannten „Logik der Mode“. (...) Gombrich hat dargelegt, auf welch vielfältige Weise Veränderungen in der Kunst sich vollziehen. Während sich die Moden in der Kunst auf unvorhersehbare, launenhafte Weise wandeln, tauchen technische Veränderungen als Lösungen für technische Probleme auf und werden im Modus von Versuch und Irrtum ermittelt. Auf diese Weise stieß Gombrich auf eine Antinomie in der Kunsttheorie: Handwerkliche Fähigkeiten und Können wandeln sich durch rationalen Fortschritt, während sich Stile durch den irrationalen Mitläufereffekt verändern. In der Kunst ist der relativistische Pluralismus zur Mode geworden, und diese Mode hat seine Antinomie ignoriert – und zwar, sofern er richtig liegt, recht willkürlich. (shrink)

People have become increasingly conscious of the moral implications of their meat product consumption. The view that farm animals deserve moral considerations has generated widespread public attention to those animals’ welfare. Meat products from ethically raised animals are distinguished from non-welfare products using animal welfare-friendly (AWF) labels, such as the Better Life Trademark in the Netherlands. AWF meat products have become popular in the Netherlands, as evidenced by a substantial growth in product sales. To address the question concerning the factors (...) influencing people’s intention to purchase AWF meat products and the extent to which those factors relate to one another, an online survey was implemented with 233 consumers from the Netherlands. Structural equation modeling results confirm the complexity of the mechanism behind people’s willingness to buy AWF meat products. Two factors strongly predict purchase intention—attitude and moral obligation. Furthermore, the effects of predictors such as knowledge of and trust in AWF labels on purchase intention are not direct but go through attitude and moral obligation. (shrink)

In days past, epistemologists expended a good deal of effort trying to analyze the basing relation—the relation between a belief and its basis. No satisfying account was offered, and the project was largely abandoned. Younger epistemologists, however, have begun to yearn for an adequate theory of basing. I aim to deliver one. After establishing some data and arguing that traditional accounts of basing are unsatisfying, I introduce a novel theory of the basing relation: the dispositional theory. It begins with the (...) pedestrian observation that beliefs stand or fall with their bases. The theory I offer is an elucidation and refinement of this thought. (shrink)

A survey of Euclid's Elements, this text provides an understanding of the classical Greek conception of mathematics and its similarities to modern views as well as its differences. It focuses on philosophical, foundational, and logical questions — rather than strictly historical and mathematical issues — and features several helpful appendixes.

2020 CHOICE Outstanding Academic Title In this book, Philipp von Wussow argues that the philosophical project of Leo Strauss must be located in the intersection of culture, religion, and the political. Based on archival research on the philosophy of Strauss, von Wussow provides in-depth interpretations of key texts and their larger theoretical contexts. Presenting the necessary background in German-Jewish philosophy of the interwar period, von Wussow then offers detailed accounts and comprehensive interpretations of Strauss's early masterwork, Philosophy and Law, his (...) wartime lecture "German Nihilism," the sources and the scope of Strauss's critique of modern "relativism," and a close commentary on the late text "Jerusalem and Athens." With its rare blend of close reading and larger perspectives, this book is valuable for students of political philosophy, continental thought, and twentieth-century Jewish philosophy alike. It is indispensable as a guide to Strauss's philosophical project, as well as to some of the most intricate details of his writings. (shrink)

An expanded & revised version of Religion in an Age of Science. Three new chapters on physics & metaphysics in the 18th century and biology & theology in the 19th century. Other new sections included.

Kant conceived of 'critique' as a kind of winnowing exercise, with the aim of separating the wheat of good metaphysics from the chaff of bad. He used a less familiar metaphor to make this point, namely, that of 'the fiery test of critique'-not a medieval ordeal of trial by fire, but rather a metallurgical assay, or cupellation, a procedure in which ore samples are tested for their precious-metal content. When seen in this light, critique has a positive, investigatory side: it (...) seeks not merely to eliminate bad, 'dogmatic' metaphysics but also to uncover what of philosophical value might be contained in traditional speculative metaphysics. In this comprehensive study of the Transcendental Dialectic in Kant's Critique of Pure Reason, Proops argues that Kant uncovered two nuggets of value: the indirect proof of Transcendental Idealism afforded by the resolution of the Antinomies, and a defence of theoretically grounded 'doctrinal beliefs' in a wise and great originator, on the one hand, and in an afterlife, on the other. This examination of critique engages with Kant's views on a number of central problems in philosophy and meta-philosophy: the explanation of the enduring human impulse towards metaphysics, the correct philosophical method, the limits of self-knowledge, the possibility of human freedom, the resolution of metaphysical paradox, the justification of faith, the nature of scepticism, and the role of 'as if' reasoning in natural science.

Many epistemologists have recently defended views on which all evidence is true or perceptual reasons are facts. On such views a common account of basic perceptual reasons is that the fact that one sees that p is one’s reason for believing that p. I argue that that account is wrong; rather, in the basic case the fact that p itself is one’s reason for believing that p. I show that my proposal is better motivated, solves a fundamental objection that the (...) received view faces, and illuminates the nature of reasons for belief. (shrink)

Most contemporary theorists regard the traditional thesis that perception is essentially conscious as just another armchair edict to be abandoned in the wake of empirical discovery. Here I reconsider this dramatic departure from tradition. My aim is not to recapture our prelapsarian confidence that perception is inevitably conscious (though much I say might be recruited to that cause). Instead, I want to problematize the now ubiquitous belief in unconscious perception. The paper divides into two parts. Part One is more purely (...) philosophical. It explains how standard arguments for unconscious perception rely on contentious background assumptions concerning the relation between ordinary perception and the explanatory constructs of scientific psychology. Part Two, in contrast, offers detailed engagement with relevant empirical work. It exposes how, even setting aside the concerns identified in Part One, a dilemma confronts the believer in unconscious perception. This dilemma arises because ordinary perception is an individual-level state or occurrence, yet criteria sufficiently stringent to guarantee that a putatively perceptual state is unconscious vitiate the grounds for its attribution to the individual. The dilemma foments a hypothesis, namely that the conditions for genuine, individual-level perception are sufficient conditions for perceptual consciousness. The viability of this hypothesis should unnerve anyone who thinks unconscious perception is simply an empirical given. (shrink)

Philosophers have lately seized upon Sperling's partial report technique and subsequent work on iconic memory in support of controversial claims about perceptual experience, in particular that phenomenology overflows cognitive access. Drawing on mounting evidence concerning postdictive perception, I offer an interpretation of Sperling's data in terms of cue-sensitive experience which fails to support any such claims. Arguments for overflow based on change-detection paradigms (e.g. Landman et al., 2003; Sligte et al., 2008) cannot be blocked in this way. However, such paradigms (...) are fundamentally different from Sperling's and, for rather different reasons, equally fail to establish controversial claims about perceptual experience. (shrink)
