God's necessary existence makes sense. Attempt at a transcendental modal proof. - In this essay I outline a novel three-stage proof of God's necessary existence using transcendental and deductive methods. In the first step of the proof, by retorsion, it is proved that there is at least one sentence that is necessary and inescapable. In the second step, the inescapability of the modal logic supposed in the proof is shown. This step also contains a new argument in favour of epistemic (...) anti-realism. The third step finally proves the necessary existence of the person who proves. The proof thus refers to the subject, the object, and the method of this proof itself. (shrink)

I examine the extent to which God is inscrutable to human reason in Kant's critical philosophy. I argue that Kant's view here is much more radical than the rationalist commonplace that we cannot grasp how divine perfection is compatible with the existence of (apparent) imperfections. In Kant's considered view, we are absolutely incapable of accurately representing God's nature in any minimally determinate way: when we try to go beyond the empty idea of a mere 'something', we inevitably distort the nature (...) of God in an anthropomorphic fashion. The reason for this radical inscrutability of God is that our discursive intellect with its finite conceptual resources cannot capture the nature of a supremely perfect being. Our only way to form a legitimate, positive notion of God is by means of an analogy with the features that we objectively cognize in finite beings. (shrink)

In Fear and Trembling Kierkegaard writes that Abraham intended to sacrifice Isaac for God’s sake as well as for his own sake. Drawing mainly on The Sickness unto Death I will argue that Kierkegaard construes Abraham as becoming a true self, that is, as someone who becomes self-transparent before God. What this means and how our relationship with God is supposed to be involved in the process of becoming a self is the focus of my paper. While various articles have (...) been written on that topic, my aim here is to give the most charitable interpretation of Kierkegaard’s theses and the theological concepts involved. (shrink)

Summary This paper deals with the structure of the so-called c-inductive arguments in Richard Swinburne’s book The Existence of God and attempts to criticize their central concepts and assumptions. One of these concepts is simplicity: it is argued that Swinburne’s concept of simplicity is not unambiguous and that there is no reason to assume a positive correspondence between simplicity and probability. Furthermore, the theistic hypothesis cannot be said to be simple in any sense relevant to Swinburne. The second important concept (...) is explanatory power. It is argued that the method of determining a theory’s probability by means of its explanatory power cannot be applied to the case of theism. Finally, polytheism is considered and it is argued that according to his own principles Swinburne has actually no sufficient reason to prefer monotheism. (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.

Max Scheler's concept of the “becoming god” and its implication of mankind as his “ally” has been a long-time target of relentless criticism. The strongest objections were made mainly against the tendency of overestimating the human share in the affairs of being, culminating in the groundless self-idealization of mankind. Put aside these fierce reactions, Scheler's notion of “being in progress” however seems to be accurate overall: If the spheres of being can be described as matter, life and spirit, and the (...) balance between all of them is what defines being as a whole, then currently being is indeed not fully existent yet and therefore still has to be unfolded. Strangely enough, in Scheler's view it is mainly the lower spheres of being, more precisely the urge of life (“Lebensdrang”) that holds the power of unfolding all other – without it, pure spirit would have been absolutely powerless. In this sense, the life-related power of mankind holds the potential to help evolving the higher spheres of being, since natural evolution (at least in terms of experience) has mostly come to an end for the contemporary human race. Henceforth, helping spirit unfold is a matter of intentional decision, since it doesn't unfold by default anymore. When assuming Scheler's term of eros as the mediator between life and spirit, mankind analogously seems to become the becoming god's eros. In this article, I explore what the implications of this conclusion might be. (shrink)

Abstract: Four main forms of Doomsday Argument (DA) exist—Gott’s DA, Carter’s DA, Grace’s DA and Universal DA. All four forms use different probabilistic logic to predict that the end of the human civilization will happen unexpectedly soon based on our early location in human history. There are hundreds of publications about the validity of the Doomsday argument. Most of the attempts to disprove the Doomsday Argument have some weak points. As a result, we are uncertain about the validity of (...) DA proofs and rebuttals. In this article, a meta-DA is introduced, which uses the idea of logical uncertainty over the DA’s validity estimated based on a virtual prediction market of the opinions of different scientists. The result is around 0.4 for the validity of some form of DA, and even smaller for “Strong DA”, which predicts the end of the world in the near term. We discuss many examples of the validity of the DA in real life as an instrument to prove it “experimentally”. We also show that DA becomes strongest if it is based on the idea of the “natural reference class” of observers, that is, the observers who know about the DA (i.e. a Self-Referenced DA). Such a DA predicts that there is a high probability of a global catastrophe with human extinction in the 21st century, which aligns with what we already know based on analysis of different technological risks.

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)

At Temple College, a community college in Texas, the administration forced Kerry Laird, a literature and composition professor, to remove from his office door the quote from Friedrich Nietzsche "Gott ist tot."

The physicist J. Richard Gott has given an argument which, if good, allows one to make accurate predictions for the future longevity of a process, based solely on its present age. We show that there are problems with some of the details of Gott's argument, but we defend the core thesis: in many circumstances, the greater the present age of a process, the more likely a longer future duration.

SummaryHolm Tetens develops in his book „Gott denken. Ein Versuch über rationale Theologie“ theoretical and practical arguments against a naturalistic and in favour of a theistic understanding of reality. In my paper I focus on Teten’s claim that we are rationally justified to hope for the truth of classical theism. I distinguish between rationally justified and unjustified forms of hope and argue that we are rationally justified to hope for the redemption of reality as promised by classical theism. However, (...) this hope has a weaker basis of justification than Tetens seems to assume because serious objections to classical theism ought to be taken into consideration as well. (shrink)

Die anhaltende Popularität von juristisch geprägter Literatur zeigt, dass das Ringen um die Gerechtigkeit im Recht ein brisantes Thema ist, das gesellschaftliche Aufmerksamkeit auf sich zieht, provoziert und immer wieder neu zum Nachdenken herausfordert. Zeitgenössisch sind es Autor*innen wie Juli Zeh, Bernhard Schlink, Georg Oswald oder Ferdinand von Schirach (sogenannte Dichterjurist*innen 1 ), die die Frage nach Recht und Gerechtigkeit literarisch verbinden und deren Problemkontexte beleuchten. Juli Zeh lässt ihrem Roman Spieltrieb die Erzählerinstanz sprechen: „Das Recht ist kein Kreißsaal für (...) die Gerechtigkeit […]“ (2013, 518). Auch Ferdinand von Schirach bemüht sich herauszustellen, dass für ihn Recht nicht gleich Gerechtigkeit bedeutet. Als Strafverteidiger sagt er über die Justiz: „[W]ir sprechen […] nicht Gerechtigkeit, sondern Recht“ (Heise 2009).3 In seinen Bestsellern (angefangen von z. B. Der Fall Collini über Terror bis zu seinem neusten Stück Gott) provoziert er das Gerechtigkeitsempfinden seiner Leser*innen und lässt sie am Ende gerne selbst das Urteil fällen. In Terror (2016) soll das Publikum als Jury selbst entscheiden, ob der Kampfpilot das entführte Passagierflugzeug, das auf ein voll besetztes Fußballstadion zugesteuert ist, hätte abschießen dürfen. Hier geraten u. a. die Gewissensentscheidung des Piloten und die Rechtsgrundlage in einen Konflikt. Nicht selten macht er den Leser*innen das Recht schwer erträglich, wenn er z. B. wie im Erzählband Schuld (2017) auf brutale Weise beschreibt, wie eine minderjährige Kellnerin auf einem Volksfest von einer Gruppe von Männern vergewaltigt wird, aber aus Beweismangel letztendlich keiner dieser Männer schuldig gesprochen werden kann. In der Literatur werden vielfältige Zugänge zum Verhältnis von Recht und Gerechtigkeit eröffnet – wie kann sich die christliche Sozialethik positionieren? (shrink)

Herder’s earliest philosophical writing, the essay fragment Versuch über das Sein, explores the concept of Being (Sein) in dialogue with Kant’s pre-critical Der einzig mögliche Beweisgrund zu einer Demonstration des Daseins Gottes. In this often critically omitted work, Herder arrives at a number of insights that would be determinative for the development of his later thought. This examination details Herder’s concept of Being as the transcendent ground of predication, his contention that Being can never be experienced directly, and his consequent (...) conclusion that the shape of philosophical inquiry should not be one of abstract speculation, but instead one of non-foundational, historically aware, empirical observation. This consideration then briefly addresses how the concept of Being informs Herder’s philosophy of science, history, language and religion. (shrink)

Franz C. Brentano, 'La psicología de Aristóteles, con especial atención a la doctrina del entendimiento agente. Seguida de un apéndice sobre la actividad del Dios aristotélico'. Traducción y presentación de David Torrijos Castrillejo. Madrid, Ediciones Universidad San Dámaso, 2015, ISBN: 978-84-15027-81-2, xix + 344 pp. Título original: 'Die Psychologie des Aristoteles insbesondere seine Lehre vom ΝΟΥΣ ΠΟΙΗΤΙΚΟΣ. Nebst einer Beilage über das Wirken des Aristotelischen Gottes'. Mainz: Franz Kirchheim, 1867.

Metaphysics and psychology are two of Brentano’s main areas of interest in philosophy. His first writings, the dissertation On the Several Senses of Being in Aristotle (1862) and the habilitation thesis, The Psychology of Aristotle (1867), bear witness to the duality of his concerns. As such, these works were not only significant contributions to the German Aristotelianism of the second half of the XIXth century, but they also played an important role in the development of Brentano’s later philosophy and in (...) defining his school of thought. At the same time, the dissertation, now celebrating the sesquicentennial of its first publication, was received beyond the immediate sphere of the Brentanian school, for its reading played a significant role in young Heidegger’s thought on being, and thus in his development of a new type of phenomenology, distinct from the Husserlian one. The studies comprising this volume examine the relevance of Brentano’s dissertation, of his metaphysics and psychology for contemporary philosophical research. Generally, the papers emphasize a tendency in Brentanian research, which has become more conspicuous in the last two decades, and can be described as a gradual shift in focus from the specific problems of Brentano’s late philosophy, towards his earlier philosophy, especially his first writings and manuscripts. Taking into account both Brentano’s published works, and the manuscripts of the dissertation and the Psychology, the contributions of this volume manage to emphasise unexplored aspects of Brentano’s philosophy and stand witness to the complexity and the historical dimension of a legacy whose richness still awaits full discovery. -/- Table of Contents -/- Ion Tănăsescu, Foreword Edoardo Fugali, Trendelenburg, Brentano und die Aristoteles-Renaissance in der deutschen Philosophie des 19.

A suggestion famously made by Peter Winch and carried through to present discussions holds that what constitutes the social as a kind consists of something shared – rules or practices commonly learned, internalized, or otherwise acquired by all members belonging to a society. This essays argues against the explanatory efficacy of appeals to this shared something as constitutive of a social kind by examining a violation of social norms or rules, viz., mistakes. I argue that an asymmetric relation exists between (...) the notion of mistakes and that of the social. In particular, mistakes do not presuppose a concept of the social, but the concept of the social requires prior specification of a category of mistakes. But no such prior specification proves possible. The very notion of a mistake is so inchoate that it makes it impossible to provide the kind of regimentation required for a rule-governed domain. Thus, there may be recognized mistakes even in the absence of a unified system or common knowledge of norms.Later writers attempt to avoid Winch's over-strong assumption that something shared and internal constitutes the social but cannot. Extending recent work by Stephen Turner, I argue that ``the social'' is not a domain that is susceptible to lawlike treatment, but rather a heterogeneous, motley collection. For absent the assumption of a shared something, no social object exists to be explained. So, I conclude, we have at present no clear way of marking out the social as a coherent or unified domain of inquiry. (shrink)

In Vagueness and Contradiction (2001), Roy Sorensen defends and extends his epistemic account of vagueness. In the process, he appeals to connections between vagueness and semantic paradox. These appeals come mainly in Chapter 11, where Sorensen offers a solution to what he calls the no-no paradox—a “neglected cousin” of the more famous liar—and attempts to use this solution as a precedent for an epistemic account of the sorites paradox. This strategy is problematic for Sorensen’s project, however, since, as we establish, (...) he fails to resolve the semantic pathology of the no-no paradox. (shrink)

Most models of generational succession in sexually reproducing populations necessarily move back and forth between genic and genotypic spaces.

Three theories contend as explanations of perpetrator behavior in the Holocaust as well as other cases of genocide: structural, intentional, and situational. Structural explanations emphasize the sense in which no single individual or choice accounts for the course of events. In opposition, intentional/cutltural accounts insist upon the genocides as intended outcomes, for how can one explain situations in which people ‘step up’ and repeatedly kill defenseless others in large numbers over sustained periods of time as anything other than a choice? (...) Situational explanations offer a type of behavioral account; this is how people act in certain environments. Critical to the situational account as I discuss it is the ‘Asch paradigm’, i.e. experimentally attested conditions for eliciting conformityof behavior regardlesss of available evidence of prior beliefs. In what follows, I defend what I term above a version of situational explanations of perpetrator behavior. Moreover, I maintain that the factors that explain provide an understanding as well. While not committed to the complete irrelevance or exclusion of cultural or structural factors, nonetheless situational analyses can account both for what happened and why. A cardinal virtue of this version of situational explanations consists in showing how shallow the problem of understanding turns out to be for such cases. (shrink)

We show that cast shadows can have a significant influence on the speed of visual search. In particular, we find that search based on the shape of a region is affected when the region is darker than the background and corresponds to a shadow formed by lighting from above. Results support the proposal that an early-level system rapidly identifies regions as shadows and then discounts them, making their shapes more difficult to access. Several constraints used by this system are mapped (...) out, including constraints on the luminance and texture of the shadow region, and on the nature of the item casting the shadow. Among other things, this system is found to distinguish between line elements (items containing only edges) and surface elements (items containing visible surfaces), with only the latter deemed capable of casting a shadow.

This is a sketch of the basis and role of consciousness and the minimally required elements and constraints of any setting that may produce consciousness.

This paper considers the importance of play as a conventional space for hypothetical self-expression and self-trial, its importance for determination of identity, and for development of self-possibilities. Expanding such possibilities in play enables challenging of socially entrenched assumptions concerning possible and appropriate identities. Discussion is extended to the contexts of gender performance (drag) and sport-play. It is argued that play proceeds on the basis of a fundamental pretence of reality that must be taken seriously by its participants; this discussion includes (...) considerations of serious and ironical play, “playing-at”, and travesty.

It is tough to relate visual perception or other achievements to physiological processing in the central nervous system.

In an online, participatory class, we interpreted The Dream of the Flaming Sword knowing nothing of the dreamer beyond age and gender, and having none of the dreamer’s associations.

Eight months later the bringer gave us (...) further information from the dreamer. Our predictions were mostly confirmed.

Projects of human improvement take both individual and intergenerational forms. The biosciences provide many technologies, including prenatal screening and the latest gene editing techniques, such as CRISPR, that have been viewed as providing the means to human improvement across generations.

The ways in which we exercise intentional agency are varied. I take the domain of intentional agency to include all that we intentionally do versus what merely happens to us. So the scope of our intentional agency is not limited to intentional action. One can also exercise some intentional agency in omitting to act and, importantly, in producing the intentional outcome of an intentional action. So, for instance, when an agent is dieting, there is an exercise of agency both with (...) respect to the agent’s actions and omissions that constitute her dieting behavior and in achieving the intended outcome of losing weight. In our mental lives we exercise intentional agency both in performing mental actions and when we intentionally produce certain outcomes at which our mental actions are aimed. The nature and scope of our intentional agency in our mental lives with respect to controlling the acquisition of mental states such as belief, desire, and intention is a topic that is of interest in its own right. In this essay, I will focus solely on our control over coming to believe. Understanding what sort of control we have our beliefs has far-reaching implications. For instance, theorizing about self-deception and wishful thinking is aided by theorizing about what if any intentional agency we can exercise with respect to acquiring beliefs. Another often mentioned concern that motivates thinking about doxastic agency comes from religion (when conversion requires a change of belief). We also hold persons morally and epistemically responsible for beliefs they have or fail to have. Finally, some deontological theories of epistemic justification require that agents be able to exercise a robust form of doxastic control. Fruitful work on any of these problems requires that we have an account of our intentional agency in acquiring beliefs. There are at least three loci of doxastic control. The first is over acquiring beliefs. The second is over maintaining beliefs. The third is over how we use our beliefs. I am chiefly concerned with the first locus of doxastic control in this essay, but I will say something about the second locus along the way. Also, I will only consider one way we might exercise control over acquiring beliefs. Specifically, I will present an argument against direct doxastic voluntarism (DDV). By “DDV” I mean to refer to the thesis that it is conceptually possible for agents to consciously exercise the same sort of direct voluntary control over coming to acquire a doxastic attitude—such as belief, suspension of belief, and disbelief—that they exercise over uncontroversial basic actions. If DDV is correct, then coming to believe can be a basic action-type. DDV, or something very close to it, was Bernard Williams’ target in his 1973 paper, “Deciding to Believe.” Williams’s argument is widely regarded as having been a failure. But I think that Williams was on to something in his paper. Hence, in this paper, while I do not attempt to resurrect Williams’s argument, I develop and defend a revised argument for a thesis that is quite close to Williams’s. I will proceed as follows. First, I will discuss Bernard Williams’ (1973) failed attempt at showing that DDV is conceptually impossible. This will be followed by a discussion of some constraints on our belief-forming activities. I will then clarify my target a bit more than Williams does in his original paper. Finally, I will present my own argument against the conceptual possibility of DDV. (shrink)

One of the more compelling beliefs about vision is that it is based on representations that are coherent and complete, with everything in the visual field described in great detail. However, changes made during a visual disturbance are found to be difficult to see, arguing against the idea that our brains contain a detailed, picture-like representation of the scene. Instead, it is argued here that a more dynamic, "just-in-time" representation is involved, one with deep similarities to the way that users (...) interact with external displays. It is further argued that these similarities can provide a basis for the design of intelligent display systems that can interact with humans in highly effective and novel ways. (shrink)

Contrasting two models of deliberative democratic multiculturalism, one by Seyla Benhabib and another by Luis Villoro, this paper contends that the differences between these two models outweigh the similarities, and that Villoro’s model is more promising insofar as it preserves the trust required in the institutions that mediate democratic deliberation in multicultural societies.

Focused attention is needed to perceive change (Rensink et al., 1997; Psychological Science, 8: 368-373) . But how much attentional processing is given to an item? And does this depend on the nature of the task? To answer these questions, "flicker" displays were created, where an original and a modified image continually alternated, with brief blanks between them. Each image was an array of simple figures, half being horizontal and the other half vertical. In half the trials, one of the (...) items changed orientation; in the remainder, all items remained the same. Observers were asked to detect whether a change was occurring in each trial. -/- Within-observer comparisons for different shapes of items yielded two classes of speed: relatively fast search (50 ms/item) for simple lines, and slower search (90 ms/item) for compound figures made of two or more lines. Evidently, more processing was given to compound figures, even though shape was irrelevant to the task. A similar set of experiments asked observers to detect changes in contrast polarity. Here, no differences were found for different shapes, indicating that geometric information is not processed as much when the task involves only nongeometric properties. (shrink)

A modified visual search task demonstrates that humans are very good at resuming a search after it has been momentarily interrupted. This is shown by exceptionally rapid response time to a display that reappears after a brief interruption, even when an entirely different visual display is seen during the interruption and two different visual searches are performed simultaneously. This rapid resumption depends on the stability of the visual scene and is not due to display or response anticipations. These results are (...) consistent with the existence of an iterative hypothesis-testing mechanism that compares information stored in short-term memory (the perceptual hypothesis) with information about the display (the sensory pattern). In this view, rapid resumption occurs because a hypothesis based on a previous glance of the scene can be tested very rapidly in a subsequent glance, given that the initial hypothesis-generation step has already been performed.

Recent developments in vision science have resulted in several major changes in our understanding of human visual perception. For example, attention no longer appears necessary for "visual intelligence"--a large amount of sophisticated processing can be done without it. Scene perception no longer appears to involve static, general-purpose descriptions, but instead may involve dynamic representations whose content depends on the individual and the task. And vision itself no longer appears to be limited to the production of a conscious "picture"--it may also (...) guide processes outside the conscious awareness of the observer. (shrink)

If we conceive of ourselves as animals, it might be accurate to call us visual animals. The visual cortex is much larger in us relative to the size of our brains than in other animals, and large relative to the parts of the cortex responsible for the transmission of signals emanating from the other perceptual transducers. Our ability to recall visual images, recombine them in imagination and enter imaginatively into narratives is linked to this evolved piece of brain architecture. However, (...) what this means within the context of human culture is not so clear. A large visual cortex might not necessarily translate into a heightened susceptibility for fine visual distinctions over auditory or kinetic distinctions, at least not in all cultural contexts.

In this paper we examine to what extent the lengths of the links in an animated articulated figure can be changed without the viewer being aware of the change. This is investigated in terms of a framework that emphasizes the role of attention in visual perception. We conducted a set of five experiments to establish bounds for the sen-sitivity to changes in length as a function of several parameters and the amount of attention available. We found that while length changes (...) of 3% can be perceived when the relevant links are given full attention, changes of over 20% can go unnoticed when attention is not focused in this way. These results provide general guidelines for algorithms that produce or process character motion data and also bring to light some of the potential gains that stand to be achieved with attention-based algorithms.

Among moral philosophers, general disapproval of genetic enhancement has in recent years given way to the view that the permissibility of a eugenic policy depends only on its particular features. Buchanan, Brock, Daniels, and Wikler have extensively defended such a view. However, while these authors go so far as to argue that there are conditions under which parents are not only permitted but also obligated to procure genetic treatments for their intended child, they stop short of arguing that there are (...) conditions under which parents are required to procure enhancements. By contrast, David Heyd argues that parents are required to procure treatments or enhancements for their future child, but only if the intervention would not alter the future child’s personal identity. In this paper I take the case for genetic enhancement a step further by arguing that there are conditions under which parents are morally required to procure genetic interventions for their intended child, regardless of whether the intervention is a treatment or an enhancement, and regardless of whether it would alter the child’s personal identity.

In fundamental rights adjudication, should judges defer to the judgment of other decision makers? How can they defer, without betraying the respect that judges ought to accord those rights? How can they refuse to defer, without betraying the respect that judges ought to accord to other decision makers? I argue that only principles of comity justify deference, and their reach is limited. Comity never forbids the judges to take and to act upon a different view of fundamental rights from that (...) of another decision maker. I elaborate this view by reference to the decision of the House of Lords in Adan and Aitseguer [2001] 1 All ER 593. (shrink)

Purpose. To determine whether highlights are rapidly identified at early levels of vision. -/- Methods. Visual search experiments were carried out using simple black and white figures corresponding to shiny objects lit from various directions. These included, for example, depictions of cylinders with highlights positioned at various heights (see figure). Targets and distractors differed only in the arrangement of their constituent regions, allowing them to be distinguished by the position of the highlights on the corresponding objects. -/- Results. Three observers (...) were tested. Search is rapid when the target corresponds to a shiny black object with a bottom highlight among objects with top highlights (view figure from rightside up). However, search slows down when the target corresponds to an object with a top highlight among objects with bottom highlights (view figure from upside down). This asymmetry in search speeds is destroyed when the contrast of the figures is reversed. -/- Conclusions. These results indicate that regions in the image can be rapidly identified as highlights at early levels of vision. They also suggest--as for several other rapid recovery processes--that an assumption of lighting from above is used as a simplifying constraint. (shrink)

I argue for two controversial claims about Locke’s account of liberty in Essay 2.21. The first claim is that Locke does not identify liberty with freedom of action. Instead, Locke places further conditions on liberty beyond to the power to perform or forbear an action at will. The second (and closely related) claim is that Locke takes the power to suspend and examine desire to be necessary for liberty—in other words, that possession of the power to suspend and examine desire (...) is one such further condition upon liberty.
