“Descartes on Spontaneity, Indifference, and Alternatives” This essay argues for a “two‐way” compatibilist reading of Descartes on the topic of free will, i.e., Descartes holds that free will is compatible with determinism, and yet also thinks that free will requires a two‐way power to pursue or avoid, and affirm or deny.

Spontaneous collapse theories of quantum mechanics require an interpretation if their claim to solve the measurement problem is to be vindicated. The most straightforward interpretation rule, the fuzzy link, generates a violation of common sense known as the counting anomaly. Recently, a consensus has developed that the mass density link provides an appropriate interpretation of spontaneous collapse theories that avoids the counting anomaly. In this paper, I argue that the mass density link violates common sense in just as (...) striking a way as the fuzzy link, and hence should not be regarded as a problem-free alternative to the fuzzy link. Hence advocates of spontaneous collapse theories must accept some violation of common sense, although this is not necessarily fatal to their project. (shrink)

Spontaneous localization theory is a quantum theory proposed by GianCarlo Ghirardi, together with Alberto Rimini and Tullio Weber in 1986. However, soon it became clear to Ghirardi that his work was more than just one theory: he actually developed a framework, a family of theories in which the wavefunction jumps, but where the ontology of the theory is underdetermined. After acknowledging that the wavefunction did not provide a satisfactory ontology, he assumed that matter was described by a continuous matter (...) density field in three-dimensional space, whose evolution is governed by a stochastic wavefunction evolution. Alternatively, Bell assumed that the wavefunction would govern a spatiotemporal event ontology, dubbed ‘flashes.’ However, not much work has been done with the perhaps most obvious possibility, namely that physical objects are made of particles. This paper has two aims. First to explain the reason why people require spontaneous localization theory to be more than just a theory about the wavefunction. This is done by showing how the problem everyone in the foundation of quantum mechanics take to be the fundamental problem of quantum mechanics, namely the measurement problem, is a red herring. Then, the paper explores the possibility of spontaneous localization theories of particles. I argue that this discussion is not a mere exercise, as spontaneous localization theories of particles may be amenable to a relativistic extension which does not require a foliation, and because in general the peculiar type of indeterminism of spontaneous localization theories may help shedding new light on the nature of the tension between quantum theory and relativity.

I argue that Kant acknowledges two models of spontaneous self-determination that rational beings are capable of. The first model involves absolute unconditional necessity and excludes any form of contingency. The second model involves (albeit not as a matter of definition) a form of contingency which entails alternative possibilities for determining oneself. The first model would be exhibited by a divine being; the second model is exhibited by human beings. Human beings do, however, partake in the divine model up to (...) an extent, namely, as far as the legislative spontaneity of their law-giving faculties are concerned. I conclude by suggesting that for Kant, the mechanistic principle that we are exclusively determined by natural causes poses a twofold threat for human agency. In one respect (in relation to the second model), it threatens us with the obliteration of contingency, or with the universality of hypothetical necessity. But in another respect (in relation to the first model), it threatens us (and our putative "laws") with the obliteration of absolute necessity, or with the universality of contingency. (shrink)

This paper examines the metaphors of 'preformation' and 'epigenesis' in Kant's Critique of Pure Reason and his other references to and various uses of theories of biological generation. It asks what these metaphor are meant to do, philosophically, and whether the idea of epigenesis, in particular, can help explain the specificity of transcendental idealism in relation to empiricism, or whether it illuminates anything concerning the status or the function of the categories. Discussing the most important interpretations of the epigenesis metaphor (...) in the Critique of Pure Reason by Philip Sloan, Günter Zöller and John Zammito, this paper suggests an alternative interpretation of the generative metaphorics surrounding Kant’s presentation of the spontaneous production of the pure concepts by the understanding. Placing the single reference to epigenesis in Critique of Pure Reason in the context of the book’s larger set of metaphors of generation, birth and biological ancestry, this paper argues that the generative model for the production or origin of the categories is in fact that of parthenogenesis, and that this is the only generative model that could have secured the epistemic status and legitimacy of the categories in the Critique of Pure Reason for Kant. This argument also reveals the gendered imaginary subtending Kant’s transcendental idealism and allows us to consider the implications of the parthenogenic model for Kant’s transcendental idealism in this light.

Two alternative accounts of quantum spontaneous symmetry breaking (SSB) are compared and one of them, the decompositional account in the algebraic approach, is argued to be superior for understanding quantum SSB. Two exactly solvable models are given as applications of our account -- the Weiss-Heisenberg model for ferromagnetism and the BCS model for superconductivity. Finally, the decompositional account is shown to be more conducive to the causal explanation of quantum SSB.

Carruthers' "immediate availability" theory of consciousness is criticized on the grounds that it offers no reasonable alternative to asserting the metaphysical impossibility of spontaneous blindsight. In defense, Carruthers says he can admit a spontaneous blindsight that relies on unconscious behavioral cues, and deny only its possibility without such mechanisms. I argue: This involves him in an unwarranted denial of the possibility that conscious visual discrimination could depend on behavioral cues. We can conceive of blindsight without behavioral cuing; if (...) we can, then we should not accept Carruthers' denial of its metaphysical possibility without good reason. To warrant this denial it is not enough to hold that the concept of consciousness employed is purely "recognitional," and thus of no relevance to modal claims. The concept is not this cognitively primitive. (shrink)

In recent years, a great deal of evidence has accumulated on the health risks and environmental impacts of some herbicides. Both conventional agriculture and agroecology are searching for alternatives to address the challenges posed by the consequences of herbicide use. In this search, peasant and indigenous agroecosystems have much to contribute since their crops evolved thousands of years ago together with diverse communities of weeds, and farmers have carried out sophisticated strategies to manage them. Through participant observation, semi-structured interviews, free (...) lists, and botanical collection, we document a milpa design that integrates and manages spontaneous vegetation to take advantage of its presence and minimize risks of crop loss. The objective of this article is to critically contrast agroecological mechanisms in this milpa design which matches the prevention principle with a set of recommendations recognized as preventive in conventional weed science.

Philosophers seeking to formulate a philosophy of mind that offers an alternative to the cur-rently dominant reductionist positions frequently appeal to the Kantian thesis that the mind is essentially spontaneous. Yet it is far from clear what the content of this thesis is, and what recommends it. In this paper, I discuss this question and propose a new answer – one that makes better philosophical and textual sense of Kant’s own claims than I believe has hitherto been offered. I (...) do this by focusing on Kant’s claim that, in particular, the represen-tation of categorial unity is spontaneous, rather than receptive. What I call the Single Spe-cies View of Spontaneity locates the rationale for this thesis in the fact that all representa-tion of categorial unity takes place in judgment and that judgment must be conceived as spontaneous. Against this I argue that Kant accepts a Two Species View of Spontaneity, according to which categorial unity can be represented in acts other than judgment. I defend this view by giving an account of Kant’s motivation for regarding categorial unity as spon-taneous, which has both a negative and a positive component. The negative component shows that categorial unity could not be accounted for by a mind whose representational capacities are entirely receptive. The positive component argues that Kant’s conception of cognition as the non-accidental agreement of a representation with its object requires him to hold that the mind is capable of an exercise of spontaneity that is directly involved in sense-perception and, therefore, distinct from judgment. It thus emerges that, properly under-stood, Kant’s thesis about the spontaneity of the mind has a much wider scope and rests on very different grounds than is commonly believed. (shrink)

The article discusses the development of modern society. In the author’s opinion, the prediction of society development is not possible due to the spontaneity of social processes. The contemporary social development is characterized by transition values: strategic instability, permanent crisis, decay of morality, degradation of the ecological environment, increase of international terrorism, danger of nuclear war, etc. Each epoch, including an epoch of uncertainty, gives rise to its own mechanisms for regulating world development, which are based on the historical memory (...) of mankind, on the acknowledgment of the value of peaceful coexistence and the acceptance of human life as the highest value. Preventing war is the main value of world development. The crucial decisions of country’s further development are dictated by the security of the state. The author demonstrates that in our time the ideal of progress evolves from the concept of accelerated innovation changes into the ideal of sustainable development, which presumes the formation of new values as a condition for the transition to new strategies of civilizational development. The current system of economic growth has its own value foundation – a consumer society. The preservation of a consumer society or the transition to alternative development scenarios largely depend on the achievements of the social sciences and humanities. The future will come without our will, but are we ready to accept this alien and unpredictable future? That is why we cannot passively await the future. The future will not arise by itself, the future will be what we make it. (shrink)

It is commonly assumed that there is some sort of tacit ’inference’ involved when we form the belief that intentional activity on the part of some (perhaps unidentified) person is causally relevant to the occurrence of some event. Against this "inferential model" of design belief formation I argue that in many ordinary cases we do not ’infer’ design beliefs at all, but that they form spontaneously and ’properly’ whenever certain conditions are met. This alternative model has a respectable historical precedent, (...) better matches our introspective judgments about design beliefs, and helps resolve a puzzling objection to the standard "fine-tuning" argument.

In Monetary Evolution, Free Banking, and Economic Order, Stephen Horwitz has provided an excellent review of the profound problems in the neoclassical theory of money and an important statement of the alternative Austrian?school approach. However, Horwitz's ?free banking? perspective rests on a false dichotomy between intervention and spontaneous order. In using the extreme case of an entirely undesigned evolutionary process to counter the equally extreme proposition that social order can be wholly designed, Horwitz loses sight of the messy world (...) of intermediate realities and possibilities. Even if money has strong spontaneous qualities, the state may play a vital role in the evolution of the financial system. (shrink)

In recent years, developmental psychologists have increasingly been interested in various forms of prosocial behavior observed in infants and young children—in particular comforting, sharing, pointing to provide information, and spontaneous instrumental helping. We briefly review several models that have been proposed to explain the psychological mechanisms underpinning these behaviors. Focusing on spontaneous instrumental helping, we home in on models based upon what Paulus :77–81, 2014) has dubbed ‘goal-alignment’, i.e. the idea that the identification of an agent’s goal leads (...) infants to take up that goal as their own. We identify a problem with the most well-known model based upon this idea, namely the ‘goal contagion’ model. The problem arises from the way in which the model specifies the content of the goal which is identified and taken up. We then propose an alternative way of specifying the content of the goal, and use this as a starting point for articulating an alternative model based upon the idea of alignment, namely the ‘goal slippage’ model. By elucidating the difference between goal contagion and goal slippage, we contribute to the articulation of experimental criteria for assessing whether and when the mechanisms specified by these two models are at work.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.2 (2002) 207-224 [Access article in PDF] Atomism, Atheism, and the Spontaneous Generation of Human Beings: The Debate over a Natural Origin of the First Humans in Seventeenth-Century Britain Matthew R. Goodrum The problem of human origins, of how and when the first humans appeared in the world, has been addressed in a variety of ways in western thought. In the seventeenth (...) century the predominant explanation for the origin of the world and the beings that inhabit it, especially human beings, was based on the biblical account of creation. It was almost universally accepted that humans had been created by a supernatural agent using supernatural means. But alternative explanations for the production of the first humans did exist, according to which the first humans were produced by nature through some form of spontaneous generation. Seventeenth-century proponents of this view differed in their conceptions of how spontaneous generation worked, but all relied heavily upon mechanisms first proposed in antiquity. Some followed the example of Aristotle and other early Greek philosophers, who had described how matter, when subjected to the correct conditions, could produce living beings. 1 Others were influenced by the modifications made to these ideas by medieval Islamic philosophers. 2 [End Page 207] A quite different conception of spontaneous generation was derived from the classical atomists, in part from certain notions attributed to Democritus of Abdera but mainly from the philosophical system of Epicurus.While any suggestion that humans might have originated naturally by some kind of spontaneous generation was widely and vigorously rejected by natural philosophers and theologians alike, the most vehement attacks were often directed against the atomists' accounts of the origin of the first humans. The reasons for this were both scientific and religious. Atomism had long been criticized for its materialism, its reliance on chance, and its atheistic tendencies. Thus, the efforts of a small number of natural philosophers to formulate and support a naturalistic explanation of human origins based upon its principles was bound to raise profound theological, philosophical, and scientific difficulties. To these natural philosophers, however, atomism seemed to offer a viable mechanism to explain spontaneous generation. Yet while atomism solved some problems, it raised others; and even if these scientific objections could be overcome, there remained religious objections to both the notion of a natural origin of humans and the atomists' account of the process that had to be addressed. Complicating matters further is the fact that these scientific and religious objections were sometimes intimately connected.This paper investigates the mechanisms proposed by atomists to explain the spontaneous generation of human beings and the kinds of criticisms their hypotheses received in seventeenth-century Britain. This will illuminate a number of interconnected issues relating to the acceptance of atomism as a philosophy of nature and its application to the biological sciences. By analyzing the ways scientific and religious factors interacted in the debate over the spontaneous generation of the first humans we will not only make a contribution to the history of seventeenth-century atomism but also link problems and ideas in the physical sciences with those in the biological and anthropological sciences. At the same time this study illustrates the ways in which scientific ideas were shaped by, or needed to respond to, ideas and concerns that had their roots in religion. Atomism and the Generation of the First Humans The most complete account of the atomic philosophy and the mechanisms it proposed to account for the origin of human beings to survive from antiquity was Lucretius's De rerum natura. Several editions of the text were available during the seventeenth century, including one published at Cambridge in 1675 and an English translation by Thomas Creech that went through four editions [End Page 208] between 1682 and 1699. 3 But Lucretius was not the only source describing the atomists' ideas about the spontaneous generation of the first humans. A more contemporary and perhaps more influential proponent of the atomic... (shrink)

The in vitro spontaneous contractions of human myometrium samples can be described using a phenomenological model involving different cell states and adjustable parameters. In patients not receiving hormone treatment, the dynamic behavior could be described using a three-state model similar to the one we have already used to explain the oscillations of intra-uterine pressure during parturition. However, the shape of the spontaneous contractions of myometrium from patients on progestin treatment was different, due to a two-step relaxation regime including (...) a latched phase which cannot be simulated using the previous model without introducing an ad hoc mechanism to account for the extra energy involved in this sustained contraction. One way to do this is to introduce an anomalous rate of ATP consumption, the biochemical reasons for which have not yet been elucidated and which cannot be mathematically simulated using our experimental data. An alternative explanation is the reduced cycling rate of actin-myosin cross-bridges known to occur during the latch-phase. Our experimental findings suggest a third possibility, namely a sol-gel transition with a specific relaxation time constant, which would maintain a significant part of the cell population in the contracted-state until the intracellular-medium returns to its normal fluid behavior.

This article explores two opposing views from Warring States China concerning the value of human natural spontaneity and large-scale government coercion. On the one hand, the Ruist philosopher Xunzi championed a comprehensive and coercive ethical, political, and social system or Way that he believed would lead to social order and moral cultivation while opposing people’s xìng. On the other hand, the authors of roughly books 8–10 of Zhuangzi, the primitivists, criticized a Way bearing a striking resemblance to Xunzi’s on the (...) grounds that it seriously harms people by opposing their xìng. I argue that the primitivists offer compelling reasons for Xunzi to modify his own Way regarding its relationship with xìng, though their own proposed alternative Way is not very attractive. I conclude with a brief discussion of one primitivist-inspired alternative view found in the Lü Shi Chun Qiu, which plausibly suggests that one way of respecting people’s xìng is by offering them opportunities to explore their natural abilities.

The standard formulation of quantum gauge theories results from the Lagrangian (functional integral) quantization of classical gauge theories. A more intrinsic quantum theoretical access in the spirit of Wigner’s representation theory shows that there is a fundamental clash between the pointlike localization of zero mass (vector, tensor) potentials and the Hilbert space (positivity, unitarity) structure of QT. The quantization approach has no other way than to stay with pointlike localization and sacrifice the Hilbert space whereas the approach built on the (...) intrinsic quantum concept of modular localization keeps the Hilbert space and trades the conflict creating pointlike generation with the tightest consistent localization: semiinfinite spacelike string localization. Whereas these potentials in the presence of interactions stay quite close to associated pointlike field strengths, the interacting matter fields to which they are coupled bear the brunt of the nonlocal aspect in that they are string-generated in a way which cannot be undone by any differentiation.The new stringlike approach to gauge theory also revives the idea of a Schwinger-Higgs screening mechanism as a deeper and less metaphoric description of the Higgs spontaneous symmetry breaking and its accompanying tale about “God’s particle” and its mass generation for all the other particles.

Matthew Desmond’s “Relational ethnography,” is a manifesto for a relational turn in ethnography, liberating it from the “substantialism” of bounded places, processed people and group culture. Substantialism, however, proves to be a largely mythical category that obscures two types of relational ethnography: Desmond’s empiricist transactional ethnography and an alternative, theoretically driven structural ethnography. Drawing on Desmond’s own ethnographies, On the Fireline and Evicted, I explore the limitations of his transactional ethnography—a “spontaneous sociology” that rejects the theoretical engagement and comparative (...) logic. I elaborate and illustrate structural ethnography, drawing out the implications for public and policy sociology. (shrink)

Previous research has suggested that an effective strategy for debiasing judgments is to have participants "consider the opposite." The present research proposes that considering any plausible alternative outcome for an event, not just the opposite outcome, leads participants to simulate multiple alternatives, resulting in debiased judgments. Three experiments tested this hypothesis using an explanation task paradigm. Participants in all studies were asked to explain either 1 hypothetical outcome (single explanation conditions) or 2 hypothetical outcomes (multiple explanation conditions) to an event; (...) after the explanation task, participants made likelihood judgments. The results of Studies 1 and 2 indicated that debiasing occurred in all multiple explanation conditions, including those that did not involve the opposite outcome. Furthermore, the findings indicated that debiased judgments resulted from participants' spontaneous consideration of additional alternatives in making their likelihood judgments. The results of Study 3 also identified the perceived plausibility of the explained alternative as an important moderating variable in debiasing. (shrink)

The theoretical notion of ‘construal’ captures the idea that the way in which we describe a scene reflects our conceptualization of it. Relying on the concept of ception – which conjoins conception and perception – we operationalized construal and employed a Visual World Paradigm to establish which aspects of linguistic scene description modulate visual scene perception, thereby affecting event conception. By analysing viewing behaviour after alternating ways of describing location (prepositions), agentivity (active/passive voice) and transfer (NP/pp datives), we found that (...) the linguistic construal of a scene affects its spontaneous visual perception in two ways: either by determining the order in which the components of a scene are accessed or by modulating the distribution of attention over the components, making them more or less salient than they naturally are. We also found evidence for the existence of a cline in the construal effect with stronger expressive differences, such as the prepositional manipulation, inducing more prominent changes in visual perception than the dative manipulation. We discuss the claims language can lay to affecting visual information uptake and hence conceptualization of a static scene in the light of these results. (shrink)

ABSTRACTMethodologies and theories for writing histories of philosophy are particularly relevant today due to the abounding challenges to the discipline that have emerged: e.g. the problem concerning the precise mode of the inclusion of non-Western philosophies in the history of philosophy, the response to postcolonial considerations at large, the transformative impact of new media and the question whether the history of philosophy is primarily a philosophical, rather than merely historical, enterprise. À propos the relative scarcity that is to be witnessed (...) in explicit articulations of methodologies and theories for writing histories of philosophy, in this note I focus on certain spontaneous, rather than theoretically planned, responses that have emerged to the above challenges – in particular, Peter Adamson’s History of Philosophy without any gaps – and in conclusion, as an example of methodological development, I touch on some of the problems we encounter in the case of the inclusion of Byzantine philos...

We present a model of a fundamental property of consciousness as the capacity of a system to opt among presented alternatives. Any system possessing this capacity is "conscious" in some degree, whether or not it has the higher capacity of reflecting on its opting. We argue that quantum systems, composed of microphysical particles, as studied by quantum mechanics, possess this quality in a protomental form. That is, such particles display the capacity to opt among alternatives, even though they lack the (...) ability to experience or communicate their experiences. Human consciousness stands at the opposite end of the hierarchy of conscious life forms as the most sophisticated system of which we have direct acquaintance. We contend that it shares the common characteristic of a system capable of opting among alternatives. Because the fundamental property of consciousness is shared by human beings and the constituents of elementary matter in the universe, our model of consciousness can be considered as a modified form of panpsychism.

In this study, I present the Chan Buddhist alternative to phronesis or ‘practical wisdom’. Instead of involving the skill or ‘know-how’ in applying moral principles to particular situations, the Chan Buddhist virtuously responds to situations because they understand how each situation is a ‘part’ of a larger whole or a ‘function’ (用) of the ‘body’ (體). Ultimately, this sensitivity to how each situation is meaningfully situated within a context of relationships is what motivates the Chan Buddhist’s spontaneous compassion towards (...) the suffering of existence in its entirety.

Skepticism toward the existence of neonatal differential imitation is fostered by views that assign it an excessive significance, making it foundational for social cognition. Moreover, a misleading theoretical framework may generate unwarranted expectations about the kinds of findings experimentalists are supposed to look for. Hence we propose a theoretical analysis that may help experimentalists address the empirical question of whether early differential imitation really exists. We distinguish three models of early imitation. The first posits automatic visuo-motor links evolved for sociocognitive (...) functions and we call it Genetically Programmed Direct Matching. The second is Meltzoff and Moore’s Active Intermodal Matching, which postulates a comparison between the acts of self and other. The third is the alternative we propose and we call it “Association by Similarity Theory”, as it relies on the tacit functioning of this domain-general process. AST describes early imitation merely as the differential induction or elicitation of behaviors that already tend to occur spontaneously. We focus on the contrast between AIM and AST, and argue that AST is preferable to AIM for two reasons. First, AST is more parsimonious and more plausible, especially because it does not require infants to be able to recognize self-other similarities. Second, whereas the extant findings tend to disqualify AIM, AST can account for them adequately. Furthermore, we suggest that AST has the potential to give new impulse to empirical research because it discriminates promising lines of inquiry from unproductive ones. (shrink)

To morally defer is to form a moral belief on the basis of some credible authority's recommendation rather than on one’s own moral judgment. Many philosophers have suggested that the sort of knowledge yielded by moral deference is deficient in various ways. To better appreciate its possible deficiencies, I propose that we look at a centuries-long philosophical discourse that made much of the shortcomings of this sort of knowledge, which is the discourse about “getting it oneself” (zide 自得) in the (...) later (post-classical) Confucian tradition. In this chapter, I offer the first sustained philosophical account of “getting it oneself,” as conceived by its most influential proponents—Cheng Hao, Cheng Yi, and Zhu Xi. I describe its most notable features, including its tendency to enhance epistemic confidence and what I call “self-discovery aspects” of the phenomenon. I then focus on the Neo-Confucian claim that some parts of the deliberative process should be spontaneous or unforced, which, I argue, they saw as necessary for an unbiased appreciation of the inferential force of the reasons for one’s moral conclusions. I conclude by pointing to some of the broader implications of my reading for both the history of philosophy and current debates about moral deference. (shrink)

Open peer commentary on the article “Second-Order Science of Interdisciplinary Research: A Polyocular Framework for Wicked Problems” by Hugo F. Alrøe & Egon Noe. Upshot: Contrary to Alrøe and Noe, problems are wicked not because they escape the technical expertise of the special sciences but because they reawaken the sciences’ totalizing impulse, which then leads to conflicting cross-disciplinary claims, on the basis of which the state must intervene. This situation is understandable against the backdrop of an “open systems” perspective, in (...) which the sort of second-order perspective presupposed by wicked problems is spontaneously generated.

One of the most original assumptions is that political actors are groups of thematized information. They effectively test the political, traditional sources of meaning, and reservoirs of identity. The post-religiousness of the presentness is transcendentally neutral; there is no contradiction between the transcendental and the immanent. Why and how relics steal into the political? The social does not create any meaning considerably stronger than the empty meanings of dedicated metaphysics and discourses, but the social creates itself within the totariental (total (...) - poleless - disorienting). The book contains analyses of the implementation of political crises and crises of the political. In other words, two processes are simultaneously used by political actors in contemporary democracy. These tools are not only moderators of naturally spontaneous democracy. Economic, cultural, and political changes are pressed ahead by technically, sociologically and military equipped actors for whom democracy is efficient. (shrink)

Four Challenges to Epistemic Scientific Realism—and the Socratic Alternative.

People tend to prefer fluently processed over harder to process information. In this study we examine two issues concerning fluency and preference. First, previous research has pre-selected fluent and non-fluent materials. We did not take this approach yet show that the fluency of individuals’ idiosyncratic on-line interactions with a given stimulus can influence preference formation. Second, while processing fluency influences preference, the opposite also may be true: preferred stimuli could be processed more fluently than non-preferred. Participants performed a visual search (...) task either before or after indicating their preferred images from an array of either paintings by Kandinsky or decorated coffee mugs. Preferred stimuli were associated with fluent processing, reflected in facilitated search times. Critically, this was only the case for participants who gave their preferences after completing the visual search task, not for those stating preferences prior to the visual search task. Our results suggest that the spontaneous and idiosyncratic experience of processing fluency plays a role in forming preference judgments and conversely that our first impressions of preference do not drive response fluency.

This commentary criticizes nonverbal methods of assessing theory-of-mind on the basis of prior training of the critical response because they would encourage simple, nonmentalistic, associative solutions even in subjects with mentalistic capacities. I propose instead a new experimental paradigm based upon the use of spontaneous responses in less artificial situations. This method has already provided positive evidence of some level of ToM understanding in nonhuman primates.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to (...) the expression of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

Correspondence should be addressed to David A. Leopold [email protected] the viewing of certain patterns, widely known as ambiguous or puzzle figures, perception lapses into a sequence of spontaneous alternations, switching every few seconds between two or more visual interpretations of the stimulus. Although their nature and origin remain topics of debate, these stochastic switches are generally thought to be the automatic and inevitable consequence of viewing a pattern without a unique solution. We report here that in humans such perceptual (...) alternations can be slowed, and even brought to a standstill, if the visual stimulus is periodically removed from view. We also show, with a visual illusion, that this stabilizing effect hinges on perceptual disappearance rather than on actual removal of the stimulus. These findings indicate that uninterrupted subjective perception of an ambiguous pattern is required for the initiation of the brain-state changes underlying multistable vision.Visual perception involves coordination between sensory sampling of the world and active interpretation of the sensory data. Human perception of objects and scenes is normally stable and robust, but it falters when one is presented with patterns that are inherently ambiguous or contradictory. Under such conditions, vision lapses into a chain of continually alternating percepts, whereby a viable visual interpretation dominates for a few seconds and is then replaced by a rival interpretation. This multistable vision, or 'multistability', is thought to result from destabilization of fundamental visual mechanisms, and has offered valuable insights into how sensory patterns are actively organized and interpreted in the brain1, 2. Despite a great deal of recent research and interest in multistable perception, however, its neurophysiological underpinnings remain poorly understood. Physiological studies have suggested that disambiguation of ambiguous patterns. (shrink)

Although our eyes receive incomplete and ambiguous information, our perceptual system is usually able to successfully construct a stable representation of the world. In the case of ambiguous figures, however, perception is unstable, spontaneously alternating between equally possible outcomes. The present study compared EEG responses to ambiguous figures and their unambiguous variants. We found that slight figural changes, which turn ambiguous figures into unambiguous ones, lead to a dramatic difference in an ERP (“event-related potential”) component at around 400 ms. This (...) result was obtained across two different categories of figures, namely the geometric Necker cube stimulus and the semantic Old/Young Woman face stimulus. Our results fit well into the Bayesian inference concept, which models the evaluation of a perceptual interpretation’s reliability for subsequent action planning. This process seems to be unconscious and the late.. (shrink)

This paper is devoted to clarifying Hannah Arendt’s concept of political freedom by the means of analysing its structure. My analysis proceeds in three steps. Firstly, I distinguish a pre-political concept of freedom as exercising spontaneity, which is at the root of Arendt’s understanding of political freedom. Secondly, I analyse her account of freedom as exercising action and indicate its relationship to the elementary freedom of spontaneity. Arendt endowed action with a distinguished importance, since she assumed that it is the (...) only activity within the vita activa, which has a special anthropological and axiological significance. According to Arendt, only action allows one to truly experience the fundamental aspect of the human condition, which is the fact of human plurality; it is also the only activity which allows one to exercise specifically public principles, such as solidarity, equality, or justice. Thirdly, I indicate how these two accounts of freedom translate into Arendt’s concept of political freedom. This analysis reveals that the Arendtian concept of political freedom is markedly original. She did not define it in a usual manner, i.e. through indicating bundles of legal and political rights which determine the accepted scope of participation in the public affairs. The inherent part of her concept of political freedom is a specific account of how it must be exercised. Political freedom understood as the participation in governance exercised through action is not merely an activity of instrumental, but also anthropological and axiological importance, which is due to the special anthropological and axiological meaning of action. In the final section, I discuss the practical dimension of Arendt’s theory. She doubted whether the traditional representative democracy is capable of accommodating her ‘rich’ ideal of political freedom, therefore she proposed an alternative account of political system based on councils. I formulate objections against this proposition and demonstrate that councils would presumably fail to accommodate Arendt’s exacting account of political freedom. (shrink)

This paper is devoted to clarifying Hannah Arendt’s concept of political freedom by the means of analysing its structure. My analysis proceeds in three steps. Firstly, I distinguish a pre-political concept of freedom as exercising spontaneity, which is at the root of Arendt’s understanding of political freedom. Secondly, I analyse her account of freedom as exercising action and indicate its relationship to the elementary freedom of spontaneity. Arendt endowed action with a distinguished importance, since she assumed that it is the (...) only activity within the vita activa, which has a special anthropological and axiological significance. According to Arendt, only action allows one to truly experience the fundamental aspect of the human condition, which is the fact of human plurality; it is also the only activity which allows one to exercise specifically public principles, such as solidarity, equality, or justice. Thirdly, I indicate how these two accounts of freedom translate into Arendt’s concept of political freedom. This analysis reveals that the Arendtian concept of political freedom is markedly original. She did not define it in a usual manner, i.e. through indicating bundles of legal and political rights which determine the accepted scope of participation in the public affairs. The inherent part of her concept of political freedom is a specific account of how it must be exercised.

Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and descriptions of the smallest physical systems. Here, using spontaneous parametric downconversion as a heralded single-photon source, we place experimental limits on a class of alternative theories, consisting of classical field theories which result in power-dependent normalized correlation functions. In addition, we compare our results with standard quantum mechanical interpretations of our spontaneous parametric downconversion source over an order of magnitude in intensity. Our data match the (...) quantum mechanical expectations, and do not show a statistically significant dependence on power, limiting quantum mechanics alternatives which require power-dependent autocorrelation functions.
