This study introduces refutation-aware Gentzen-style sequent calculi and Kripke-style semantics for propositional until-free linear-time temporal logic. The sequent calculi and semantics are constructed on the basis of the refutation-aware setting for Nelson’s paraconsistent logic. The cut-elimination and completeness theorems for the proposed sequent calculi and semantics are proven.

The propositional nature of human associative learning is strongly supported by studies of trace eyeblink and fear conditioning, in which awareness of the contingency of a conditioned stimulus upon an unconditioned stimulus is a prerequisite for successful learning. Studies of animal lesion and human imaging suggest that the hippocampus is critical for establishing functional connections between awareness and trace conditioning.

Recent developments in psychology and neuroscience suggest away to link the mental phenomenon of visual awareness with specific neural processes. Here, it is argued that the feed-forward activation of cells in any area of the brain is not sufficient to generate awareness, but that recurrent processing, mediated by horizontal and feedback connections is necessary. In linking awareness with its neural mechanisms it is furthermore important to dissociate phenomenal awareness from visual attention or decision processes.

Awareness growth—coming to entertain propositions of which one was previously unaware—is a crucial aspect of epistemic thriving. And yet, it is widely believed that orthodox Bayesianism cannot accommodate this phenomenon, since that would require employing supposedly defective catch-all propositions. Orthodox Bayesianism, it is concluded, must be amended. In this paper, I show that this argument fails, and that, on the contrary, the orthodox version of Bayesianism is particularly well-suited to accommodate awareness growth. For it entails what I call (...) the refinement view, which allows us to capture that awareness growth consists in the increase of one’s capacity of discernment. (shrink)

Richard Bradley and others endorse Reverse Bayesianism as the way to model awareness growth. I raise a problem for Reverse Bayesianism—at least for the general version that Bradley endorses—and argue that there is no plausible way to restrict the principle that will give us the right results. To get the right results, we need to pay attention to the attitudes that agents have towards propositions of which they are unaware. This raises more general questions about how awareness growth (...) should be modelled. (shrink)

The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and link approaches, and review the relevant empirical evidence. We conclude that learning is the consequence of propositional reasoning processes that cooperate with the (...) unconscious processes involved in memory retrieval and perception. We argue that this new conceptual framework allows many of the important recent advances in associative learning research to be retained, but recast in a model that provides a firmer foundation for both immediate application and future research.

We can be aware of particulars, properties, events, propositions, facts, skills, and qualia. We can also have knowledge of and be conscious of a similar range of objects. We can, furthermore, be ignorant of such objects. Awareness is quite clearly related to knowledge, consciousness, and ignorance. But how? This entry explores some of the ways that awareness is (not) related to knowledge, consciousness, and ignorance. It also explores some of the ways that awareness might be required by, (...) and thus fundamental to, these other relations. The emerging insight is that additional clarity on the nature of awareness stands poised to add clarity to a wide range of philosophical issues in both epistemology and the philosophy of mind.

Manfred Frank has in recent publications criticized a number of prevailing views concerning the nature of self-awareness,1 and it is the so-called reflection theory of self-awareness which has been particularly under fire. That is, the theory which claims that self-awareness only comes about when consciousness directs its 'gaze' at itself, thereby taking itself as its own object. But in his elaboration of a position originally developed by Dieter Henrich (and, to a lesser extent, by Cramer and Pothast) (...) Frank has also more generally criticized every attempt to conceive original self-awareness as a relation, be it a relation between two acts or a relation between the act and itself.2 Every relation entails a distinction between two (or more) relata and, according to Frank, it would be impossible to account for the immediacy and infallibility of selfawareness (particularly its so-called immunity to the error of misidentification), if it were in any way a mediated process. Thus, self-awareness cannot come about as the result of a self-identification, a reflection, an inner vision or introspection, nor should it be conceived as a type of intentionality or as a conceptually mediated propositional attitude, all of which entails the distinction between two or more relata. The pre-reflective self-awareness of an experience is not mediated by foreign elements such as concepts and classificatory criteria, nor by any internal difference or distance. It is an immediate and direct self- acquaintance which is characterized by being completely and absolutely irrelational (and consequently best described as a purely immanent self-presence).3 Frank's approach is unusually broad, since he draws on the resources of several different philosophical traditions, including German Idealism, analytical philosophy of mind, and phenomenology. When it comes to the latter, it is particularly in Sartre that Frank has found important insights, whereas he has criticized Husserl's position persistently in most of his writings on self-awareness..

In the Critique of Practical Reason, Immanuel Kant provides two different propositions of freedom. According to the first, in the “Analytic of Pure Practical Reason,” freedom establishes the possibility of moral agency—i.e., it is the ratio essendi of the moral law. According to the second, in the “Dialectic of Pure Practical Reason,” freedom is the object of one of the practical postulates (CPrR 246–54; AA 5:132–41). Why should Kant postulate something that has been allegedly established as the ground of moral (...) agency? Does Kant appeal to two different conceptions of freedom? In this paper, I argue that Kant (1) in both cases conceives of freedom as an unconditioned form of causality, and (2) pursues two different aims according to two different but complementary arguments. On the one hand (the practical standpoint), he wants to argue that the causality of freedom is actual, through moral agency, in the domain where the laws of nature also apply. On the other hand (the theoretical standpoint), he is aware that the possibility of achieving the highest good would be compromised if we did not assume, along with the other two postulates, a world in which only the causality of freedom applies. While freedom as the ratio essendi of the moral law is actual, freedom as a postulate is a mere object of belief. (shrink)

In this study, falsification-aware semantics and sequent calculi for first-order classical logic are introduced and investigated. These semantics and sequent calculi are constructed based on a falsification-aware setting for first-order Nelson constructive three-valued logic. In fact, these semantics and sequent calculi are regarded as those for a classical variant of N3. The completeness and cut-elimination theorems for the proposed semantics and sequent calculi are proved using Schütte’s method. Similar results for the propositional case are also obtained.

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting.

Additional support is presented for the necessity of awareness of the CS-US relation in human autonomic conditioning. However, possible limitations and exceptions regarding this general rule are discussed. Limitations include the lack of relationship between conditioned response (CR) strength and degree of awareness, and an important exception may be the finding of conditioning with backwardly masked CSs of a biologically prepared nature.

Despite the recent increase in interest in philosophy about ignorance, little attention has been paid to the question of what makes it possible for a being to become aware of their own ignorance. In this paper, I try to provide such an account by arguing that, for a being to become aware of their own ignorance, they must have the mental capacity to represent something as being unknown to them. For normal adult humans who have mastered a language, mental representation (...) of an unknown is enabled by forming linguistic expressions whose content is grasped, but whose referent is unknown. I provide a neo-Fregean, a neo-Russellian, and then a unified account of this. On that basis, I then argue further that the content of ignorance can always be captured by a question. I then distinguish between propositional ignorance and non-propositional ignorance and argue that propositional ignorance attributions can be of three types, that-ignorance, whether-ignorance, and fact-ignorance. I conclude by arguing that the acquisition of truths, even when it yields knowledge that is certain, does not always eliminate one’s ignorance and that there is a degree of ignorance in almost everything we claim to know.

In lieu of an abstract, here is a brief excerpt of the content:The Awareness of the Natural World in Shinjin: Shinran's Concept of JinenDennis HirotaAttainment of Shinjin and TruthThe primary issue regarding knowledge that Shinran (1173-1263) treats in his writings concerns the commonplace, "natural" presupposition that it is constituted by an ego-subject relating itself to stable objects in the world. From his stance within Buddhist tradition, Shinran identifies the crucial problem as the human tendency toward the reification of both (...) sides of this dichotomy-resulting in an autonomous self and substantial things-with the consequent attachments fueling the afflictions ("blind passions") of habitual pain and conflict for oneself and others. The focus of Shinran's treatment of this basic Buddhist concern is the point of engagement with dharma or true reality. In this, he draws into the arena of religious faith the probing scrutiny of lingering attachments to self, even in the dedicated practitioner, that is fundamental to the critical attitude of Mahayana Buddhist tradition.My aim in taking up the issue of truth in my article "Shinran and Heidegger on Truth" in The Boundaries of Knowledge in Buddhism, Christianity, and Science 1 is to suggest a way of reading Shinran that both avoids a common pitfall that Shinran himself cautions against-an engagement with Pure Land teachings that adheres to the subject-object dichotomy of ordinary awareness-and opens up his vision to resonances with contemporary western thought, particularly continental philosophy. This latter concern is not to claim that Shinran adumbrates contemporary thought or is affirmed by resemblances, but rather seeks to cast light on compelling aspects of his thought not often treated in traditional Shin scholastics. There are, therefore, both therapeutic and constructive sides in my attempt to engage Martin Heidegger's (1889-1976) thought from a perspective rooted in Shinran's Buddhism.The pitfall in reading Shinran indicated in my article is crystallized in the assumption, prevalent in Western scholarship but also widely seen in Japan, that his Shin Buddhist path centers on a simple faith in the Pure Land teachings, with such faith understood as the subjective acceptance of the truth of doctrinal propositions. In [End Page 189] other words, it is commonly presupposed that Shin Buddhist tradition (what he terms jōdo shinshū, "the true essence of the Pure Land way") implicitly affirms the subject-object dichotomy. This difficulty is frequently compounded by formulations of the supposed tenets of belief that are heavily molded and colored by Protestant Christian notions of self, sin, eschatology, and atonement. It is impossible to take up such comparative theological issues here. 2 In a sense, I have sought in my article to circumvent a hasty assessment of conceptual equivalence by pointing out the possibility of an encompassing or prior dissonance.Since Shinran's concept of "attaining shinjin" (true entrusting, which is also the Buddha-mind given to the practitioner) is built on the endeavor to deconstruct the reification of this dichotomy in engagement with the Pure Land Buddhist path, the unconsciousness reinstatement of it in reading his writings can lead one to a thorough but easily accomplished misconstrual of his thought. My suggestion in my article is that consideration of the analogues in Heidegger's thought can help us see all this. Such comparison also appears to present a relatively untested avenue for Buddhist-Christian conversation, particularly in view of Heidegger's early indebtedness to Luther's "theology of the cross" and the notion of the "alien work of God" as the critical stripping away of attachments to human capacities (destructio in the "Heidelberg Disputation"), and also his approach to Paul's letters to the Thessalonians in The Phenomenology of Religious Life. 3 The keystone in such interreligious conversation remains, however, not simply human fallibility as subject or culpability as agent, but the persistent challenge to the subject-object dichotomy, which may form a locus of refractory difference between the religious traditions.The constructive side of the comparison concerns two general dimensions of Shinran's thought that are highlighted in an approach to his writings that might be called phenomenological. One includes a shift from a reading based on scriptural foundationalism and doctrinal reasoning to a dialogical reading, one attentive to Shinran's effort to... (shrink)

Propositional attitudes are often classified as non-phenomenal mental states. I argue that there is no good reason for doing so. The unwillingness to view propositional attitudes as being essentially phenomenal stems from a biased notion of phenomenality, from not paying sufficient attention to the idioms in which propositional attitudes are usually reported, from overlooking the considerable degree to which different intentional modes can be said to be phenomenologically continuous, and from not considering the possibility that propositional (...) attitudes may be transparent, just like sensations and emotions are commonly held to be: there may be no appropriate way of describing their phenomenal character apart from describing the properties and objects they represent.

In the waking state, in the absence of meta-awareness, mind wandering with specific contents can lead to negative mood. Such negative mood can be incorporated into dreaming according to the continuity hypothesis of dreaming. In this paper we argue that in the presence of what we call ‘sustained phenomenal meta-awareness’, negative mood would not follow mind wandering in waking. Sustained phenomenal meta-awareness has a non-sensory, non-affective phenomenal character. It is essentially intransitive, prereflectively self-aware, non-propositional, non-conceptual and (...) devoid of subject-object structure. In other words, this unique kind of meta-awareness is non-representational. Evidence is then provided that such sustained phenomenal meta-awareness can be incorporated into the subsequent dream state as non-dual lucid dreaming in which, again, no negative mood would arise. Based on the latter observation, we have coined the term ‘mindful mind wandering’ and defined it as mind wandering in the presence of sustained phenomenal meta-awareness. We argue that not only does mindful mind wandering not lead to negative mood in waking, but also its incorporation into dreaming, as non-dual lucid dreaming, result in a state that is free of negative affection.

This chapter tracks the development of the concept of self-awareness (jikaku, 自覚) in the thought of the Japanese modern philosopher Nishida Kitarō (西田幾多郎) (Kitarō Nishida) (1870–1945), founder of the Kyoto School. Nishida’s oeuvre can be divided into distinct periods, from the 1910s to the 1940s until his passing, during which he thematized and focused on different issues. Nevertheless, self-awareness is a unifying theme throughout. In the chapter we trace how Nishida develops this concept through distinct periods in his (...) career. His initial focus upon pure experience gives way to his focus upon its articulation in reflection vis-à-vis intuition as the unfolding of the will. This then leads to his thematization of the place wherein judgment or propositional thought unfolds and the broader contextual place wherein that place is situated. That thematization of place, in turn, develops into a look at the world where we interact as historical and social bodies with others (nature, other people, etc.). Nishida understands self-awareness in accordance with each of these themes in the respective periods of his oeuvre. But common to all of them is how Nishida understands self-awareness as a self-mirroring – self-reflection as reflexivity – founded upon the premise assumed by the articulated image or object of awareness, a premise necessarily irreducible to, and in excess of, the image or object. This is the a priori that Nishida for the most part calls the “absolute nothing” (zettai mu, 絶対無). To explain this Nishida makes use of Josiah Royce’s notion of a self-representative system as well as Richard Dedekind’s notion of an infinite system in his set theory. On the basis of Nishida’s references to the mathematics of set theory, I further compare his understanding of self-awareness to Kurt Gödel’s Incompleteness Theorems as well as to more recent mathematical theorists, influenced by Gödel, whose understanding of the infinite resonates with Nishida’s understanding of the absolute nothing as assumed by self-awareness.

William Lane Craig maintains that propositions and properties are not real. Yet, if we examine his proposed nominalism and his appeal to Rudolf Carnap’s linguistic frameworks, we can find that his view depends upon their reality, even as abstract objects. By drawing upon phenomenological insights, I argue that if we pay close attention to what can be before our minds in conscious awareness, we can become aware that there is more to what is real than simple, concrete particulars, even (...) in his linguistic examples. We can become aware of the reality of Platonic, ante rem universals, including propositions and properties. (shrink)

According to evidentialism, a belief is propositionally justified just in case it fits one’s evidence. A fully developed evidentialist theory of justification will require an account of the evidential fit relation. Some evidentialists have embraced an explanationist account of this relation. Some of these accounts, such as Kevin McCain’s, place an awareness requirement on evidential fit. That is, they claim that a proposition, p, fits a subject’s evidence, e, only if the subject is aware of the explanatory connection between (...) p and e. I argue by way of example that this version of explanationism fails. As a result, I suggest a friendly revision of explanationism that excludes an awareness condition. Finally, I field some objections to my version of explanationism. (shrink)

Avicenna introduces the primary propositions as the most fundamental principles of knowledge. However, as far as we are aware, Avicenna’s primaries have not yet been independently studied. Nor do Avicenna scholars agree on how to characterize them in the language of contemporary philosophy. It is well-known that the primaries are indemonstrable; nonetheless, it is not clear what the genealogy of the primaries is, how, epistemologically speaking, they can be distinguished from other principles, what their phenomenology is, what the cause of (...) the assent to them is, how to explain the relationship between the ‘innate [nature] of the intellect’ and the primaries and, finally, back to their indemonstrability, in what sense they are ‘indemonstrable’.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 101-116 [Access article in PDF] Persons and Awareness Tyson Anderson Saint Leo University The aim of this essay is to relate Christianity and Buddhism through a consideration of two key terms, "persons" and "awareness," the first being central for Christianity and the second being central for Buddhism.The first thing that needs to be noticed is the relatively indefinable character of these words. I (...) of course intend to give as clear an indication as is possible concerning their meaning, but as I considered some of the important concepts that are involved in the topic—language, world, love, understanding—I began to realize that we are surely in the realm of mystery here. By "mystery" I mean something that we can understand somewhat but cannot comprehend, much as Saint Thomas Aquinas thought of God. 1 As is well known, LudwigWittgenstein believed that there is something mysterious even about language itself, that basically what it is can be "shown" but not "said." 2 A certain tentativeness here in regard to propositional adequacy, I might add, is perfectly compatible with strong confidence in one's relation to what Wittgenstein called "the higher." 3 In regard to the truth to be found in the beliefs of others, even a megapandit such as Ken Wilber—not noted for his modesty and circumspection—observes that "the human mind is incapable of producing 100% error." 4 Perhaps some misunderstandings among those engaging in dialogue can be avoided if we remain mindful of the mysterious character of the subject matter and are less confident about the sufficiency of our own articulation of the truth.As to dialogue itself, it is perhaps well to remember when the issues of "fruit salad" and syncretism arise, 5 that thinking itself has typically a dialogical structure, with the result that "fruit salad" is actually the normal condition of persons as they develop in understanding themselves and their world. 6 In conversation with Laurence Freeman, O.S.B., the Dalai Lama appears to disapprove of mixing traditions—"Do not try to put a yak's head on a sheep's body" 7 —but it would be difficult to conceive of a more syncretistic religion than Tibetan Buddhism or Catholicism. Indeed, if we compare the early Jesus movement to the medieval church, the development of Catholicism might well be described by Luther or Calvin, had they thought of it, as an operation that put a yak's head on a sheep's body. The dialogical and finite structure of thinking is in fact one of the reasons why it is possible to conceive of a "universal religion," contrary to what the Dalai Lama thinks. 8 This is so because, since human understanding is never absolute and completed, there is always the possibility that future [End Page 101] understanding will yield a vision that embraces a multiplicity and diversity of religious insights in a way that is impossible for us to foresee at this time. Moreover, part of the point of American culture, I would think, is the benefits of mongrelization, and so perhaps Americans ought to be less suspicious than some at the thought of having "strange bedfellows." Looking for historical examples of conscious syncretism, one thinks of Mani and Jesuit syncretism exemplified in Matteo Ricci (outfitted first as a Buddhist monk and then later as a Confucian scholar) and the evangelization of New Spain, 9 and more recently, Hazrat Inayat Khan and his son, Pir Vilayat Khan. Also, there is Jesaiah Ben-Aharon, a Jewish thinker who interprets the Holocaust in terms of the Christ. 10 I find such efforts to be commendable, and so although doctrinal and cultural immaculacy has its charms, I believe it to be the call of maya. I will proceed, then, in constructing a mysterious and miscegenational fruit salad, my only justification being that this seems to reflect accurately the truth of the matter and that we really have no other peaceable choice. 11 Persons "Person" is often used in the same sense as "human being." By "person" I mean a being who can love and who, as a human being, is the... (shrink)

Terms of logic like 'all' and 'some' can be understood in relation to one another purely in thought. Individual objects of which one becomes aware by sense perception are not objects of pure thought. Hence they cannot be uniquely named. Since Aristotelian and mathematical logic deals with pure thought alone there are no singular terms in either of them. The individual constants of mathematical logic are not objects of sense perception. In Nyaya and Buddhist logic singular terms are indispensable, because (...) inference does not deal with pure thought, but with knowledge which includes both thought and sense perception. (shrink)

Among the many possible approaches to dealing with logical omniscience, I consider here awareness and impossible worlds structures. The former approach, pioneered by Fagin and Halpern, distinguishes between implicit and explicit knowledge, and avoids logical omniscience with respect to explicit knowledge. The latter, developed by Rantala and by Hintikka, allows for the existence of logically impossible worlds to which the agents are taken to have access; since such worlds need not behave consistently, the agents’ knowledge is fallible relative to (...) logical omniscience. The two approaches are known to be equally expressive in propositional systems interpreted over Kripke semantics. In this paper I show that the two approaches are equally expressive in propositional systems interpreted over Montague-Scott (neighborhood) semantics. Furthermore, I provide predicate systems of both awareness and impossible worlds structures interpreted on neighborhood semantics and prove the two systems to be equally expressive. (shrink)

In this note, I would like to focus on the two central distinctions Inan draws between varieties of ignorance. One is the distinction between “objectual” and “propositional” ignorance, and the other is the distinction between “truth-ignorance” and “fact-ignorance,” which is a distinction between two types of propositional ignorance. According to Inan, appreciating these distinctions allow us to see what is wrong with the “received view,” according to which ignorance (or awareness of it) is “always about truth,” and (...) enables us to “overcome our [philosophers’] propositional-bias.” I will argue for two theses. First, fact-ignorance appears to be a form of objectual ignorance; and, if this is so, there are no two distinctions but only one distinction that Inan in effect offers, which is between objectual and propositional ignorance. Second, what Inan calls “the received view” can raise some reasonable worries about objectual ignorance that are not taken into account by him. (shrink)

Following Smiley’s influential proposal, it has become standard practice to characterise notions of relative necessity in terms of simple strict conditionals. However, Humberstone and others have highlighted various flaws with Smiley’s now standard account of relative necessity. In their recent article, Hale and Leech propose a novel account of relative necessity designed to overcome the problems facing the standard account. Nevertheless, the current article argues that Hale & Leech’s account suffers from its own defects, some of which Hale & Leech (...) are aware of but underplay. To supplement this criticism, the article offers an alternative account of relative necessity which overcomes these defects. This alternative account is developed in a quantified modal propositional logic and is shown model-theoretically to meet several desiderata of an account of relative necessity. (shrink)

We argue that cognitive empathy and other instances of mental state attribution are a byproduct of self-awareness. Evidence is brought to bear on this proposition from comparative psychology, early child development, neuropsychology, and abnormal behavior.

This dissertation is about the structure of thought. Following Gottlob Frege, I define a thought as the sort of content relevant to determining whether an assertion is true or false. The historical component of the dissertation involves interpreting Frege’s actual views on the structure of thought. I argue that Frege did not think that a thought has a unique decomposition into its component senses, but rather the same thought can be decomposed into senses in a variety of distinct ways. I (...) extend Frege’s position and use it to develop an account of the hierarchy of senses, the senses expressed by indexicals and demonstratives, and the distinction between logical and non-logical structure. I also discuss various connections with the nature of meta-representation, our capacity for reflective judgment, some aspects of the structure of conscious experience, the way we perceive regions of space and durations of time, and our conscious awareness of our own perceptions and events of thinking.

Epistemologists who study credences have a well-developed account of how you should change them when you learn new evidence; that is, when your body of evidence grows. What's more, they boast a diverse range of epistemic and pragmatic arguments that support that account. But they do not have a satisfactory account of when and how you should change your credences when you become aware of possibilities and propositions you have not entertained before; that is, when your awareness grows. In (...) this paper, I consider the arguments for the credal epistemologist's account of how to respond to evidence, and I ask whether they can help us generate an account of how to respond to awareness growth. The results are surprising: the arguments that all support the same norms for responding to evidence growth support a number of different norms when they are applied to awareness growth. Some of these norms seem too weak, others too strong. I ask what we should conclude from this, and argue that our credal response to awareness growth is considerably less rigorously constrained than our credal response to new evidence. (shrink)

I would try to reduce the anxiety to realizing that seemingly the same proposition is really different when it is false by pointing out that the contents of two of our beliefs can be different when we think they are the same as well as being the same when we think they are different.

Trying or wanting to accurately perceive what you are thinking (...) does not guarantee success.

Over thirty years ago, Richard Rorty’s Philosophy and the Mirror of Nature declared the demise of epistemology and the arrival of a new post-Philosophical era. Rorty envisaged the intellectual activity of this predominantly literary culture as an unconstrained large-scale conversation that would flourish in an “ecstasy of spiritual freedom.” Having abandoned all systematic pretensions, edifying philosophers would add their voice to the conversation of mankind, fully aware of the radical incommensurability of the mortal vocabularies they employ. In an attempt to (...) evaluate this radical proposal, the first part of this essay argues that some of Rorty’s most memorable utopian statements are far-fetched, rhetorical and often exaggerated to the point that they damage his broad humanistic vision. Building on this, the second part discusses the “missed potential” of Rorty’s excessively broad notion of a conversation of mankind and of the uncompromisingly anti-essentialist and anti-foundationalist reorientation that he proposes.

Carruthers views unsymbolized thinking as and, therefore, as a potential threat to his mindreading-is-prior position. I argue that unsymbolized thinking may involve (non-symbolic) sensory aspects; it is therefore not purely propositional, and therefore poses no threat to mindreading-is-prior. Furthermore, Descriptive Experience Sampling lends empirical support to the view that access to our own propositional attitudes is interpretative, not introspective.

When a mental state is conscious – in the sense that there is something it is like for the subject to have it – it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a sensory quality, for (...) example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness. (shrink)

There are many reasons we might want to take the opinions of various individuals and pool them to give the opinions of the group they constitute. If all the individuals in the group have probabilistic opinions about the same propositions, there is a host of pooling functions we might deploy, such as linear or geometric pooling. However, there are also cases where different members of the group assign probabilities to different sets of propositions, which might overlap a lot, a little, (...) or not at all. There are far fewer proposals for how to proceed in these cases, and those there are have undesirable features. I begin by considering four proposals and arguing that they don't work. Then I'll describe my own proposal, which is intended to cover the situation in which we want to pool the individual opinions in order to ascribe an opinion to the group considered as an agent in its own right.

Hype over novel quantum technologies has prompted discussion on the likely societal impacts of the sector. Calls to ensure the responsible development of quantum technologies are complicated by a lack of concrete case studies or real-world examples of irresponsible quantum. At this stage, responsible quantum faces a situation reminiscent of the Collingridge dilemma. In this dilemma, the moment in which discussion on societal risks and benefits can be most impactful is also the time when the least information is available. The (...) flipside of this challenge is an opportunity to build processes for examining the public good of quantum before the trajectory (and potential problems) of the sector become “locked in”. Recent work in this space has argued that quantum researchers and innovators must work with society to address uncertainties and concerns. By engaging quantum stakeholders and understanding their perspectives on responsibility, this paper seeks to support this proposition and enable further dialogue on responsible development and use of quantum technologies.

We examine various logics that combine knowledge, awareness, and change of awareness. An agent can become aware of propositional propositions but also of other agents or of herself. The dual operation to becoming aware, forgetting, can also be modelled. Our proposals are based on a novel notion of structural similarity that we call awareness bisimulation, the obvious notion of modal similarity for structures encoding knowledge and awareness.

This paper puts forth a class of algebraic structures, relativized Boolean algebras (RBAs), that provide semantics for propositional logic in which truth/validity is only defined relative to a local domain. In particular, the join of an event and its complement need not be the top element. Nonetheless, behavior is locally governed by the laws of propositional logic. By further endowing these structures with operators—akin to the theory of modal Algebras—RBAs serve as models of modal logics in which truth (...) is relative. In particular, modal RBAs provide semantics for various well-known awareness logics and an alternative view of possibility semantics. (shrink)

Classical epistemic logic describes implicit knowledge of agents about facts and knowledge of other agents, based on semantic information. The latter is produced by acts of observation or communication, that are described well by dynamic epistemic logics. What these logics do not describe, however, is how significant information is also produced by acts of inference – and key axioms of the system merely postulate “deductive closure”. In this paper, we take the view that all information is produced by acts, and (...) hence we also need a dynamic logic of inference steps showing what effort on the part of the agent makes a conclusion explicit knowledge. Strong omniscience properties of agents should be seen not as static idealizations, but as the result of dynamic processes that agents engage in. This raises two questions: (a) how to define suitable information states of agents and matching notions of explicit knowledge, (b) how to define natural processes over these states that generate new explicit knowledge. To this end, we extend earlier epistemic “awareness models” into a dynamic system that includes acts of public observation, but also adding and dropping formulas from the currently ‘entertained’ set, we give a completeness theorem, and we show how this dynamics updates explicit knowledge. Similar ideas have been proposed before, but they were restricted to update with factual propositions; our new dynamic system applies to arbitrary formulas. We also extend our approach to multi-agent scenarios where awareness changes may happen privately. Finally, we mention further directions and related approaches. (shrink)

In her commentary of Field (1999), Hammerl (1999) has drawn attention to several interesting points concerning the issue of contingency awareness in evaluative conditioning. First, she comments on several contentious issues arising from Field's review of the evaluative conditioning literature, second she critiques the data from his pilot study and finally she argues the case that EC is a distinct form of conditioning that can occur in the absence of contingency awareness. With reference to these criticisms, this reply (...) attempts to address Hammerl's comments by exploring the issues of how awareness is defined, how it is best measured, and whether it is reasonable to believe that EC uniformly occurs in the absence of contingency awareness. The article concludes that the available evidence supports Field's proposition that EC is, in fact, Pavlovian learning. (shrink)

To approach the creation of artificial conscious systems systematically and to obtain certainty about the presence of phenomenal qualities (qualia) in these systems, we must first decipher the fundamental mechanism behind conscious processes. In achieving this goal, the conventional physicalist position exhibits obvious shortcomings in that it provides neither a plausible mechanism for the generation of qualia nor tangible demarcation criteria for conscious systems. Therefore, to remedy the deficiencies of the standard physicalist approach, a new theory for the understanding of (...) consciousness has been formulated. The aim of the paper is to present the cornerstones of this theory, to outline the conditions for conscious systems derived from the theory, and to address the implications of these conditions for the creation of robots that transcend the threshold of phenomenal awareness. In short, the theory is based on the proposition that the universe is permeated by a ubiquitous field of consciousness that can be equated with the zero-point field (ZPF) of quantum electrodynamics (QED). The ZPF, which is characterized by a spectrum of field modes, plays a crucial role in the edifice of modern physics. QED-based model calculations on cortical dynamics and empirical findings on the neural correlates of consciousness suggest that a physical system can only generate conscious states if it is capable of establishing resonant coupling to the ZPF, resulting in the amplification of selected field modes and the activation of the phenomenal qualities that are assumed to be associated with these modes. Thus, scientifically sound considerations support the conclusion that the crucial condition for generating conscious states lies in a system's capacity to tap into the phenomenal color palette inherent in the ZPF.

Against Mitchell et al.'s assertions, we argue that (1) the concordance between learning and awareness does not support any particular learning theory, (2) their propositional approach is at odds with examples of learned behaviours that contradict beliefs about causation, and (3) the relative virtues of the two approaches in terms of parsimony is more ambiguous than Mitchell et al. suggest.

The analysis of knowledge and belief has provoked intensive discussions in philosophy and linguistics. One of the issues in this area is the semantics of attitude verbs whose complement expresses a thought about the Self of the thinking person. What is the content of my belief when I think that I am tired? Some philosophers propose it is a proposition, others think it is a property. It will be shown in this essay that existing proposals in either direction are unsatisfying. (...) The property theorist expells the subject of the predicate "tired" from the analysis; their theory is at best incomplete. The propositionalist has difficulties with the analysis of the pronoun that refers back to the subject of the attitude, as is the case with "he" in "Wolfgang believes he is tired". The present new proposal ventures the idea that a conscious person is endowed with their own Logical Space that deviates from the standard model in providing for a separate entity, the Self, as the object or target of inner thoughts about oneself. Moreover, this Logical Space leaves room for linguistic error: in such a model, subjects may be unable to correctly identify the reference of a name or may fail to identify the Self with its bearer. By contrast, reference to the Self is immune to error through misidentification, it is a paradigm case of brute indexicality. In consequence, de se pronouns are rigid designators in the sense of Kripke. The book solves several puzzles of reference failure and explores numerous consequences for the semantics of attitude reports and for possible world semantics in general. (shrink)

Teacher training has the opportunity and availability to raise awarness on the happiness of teaching. The stakes are high: inclusive education contexts require teachers to fully support their pupils’ heterogeneity. The positive psychology PERMA model (Seligman, 2011) seems to be an interesting evidence-based guide to build teacher training in happiness teaching. The PERMA model (Positive emotions, Engagement, Relationships, Meaning, Achievement) provides an identification of the different factors needed for this happiness teaching training. It also highlights the importance of the teacher-pupil (...) relationship. This fundamental relationship is key to the classroom climate. It allows teachers to nurture the joy of teaching as well as learning, sharing a school project, and progressing -together with their pupils- to a common goal. In this vein, teacher training can give itself the means to foster socio-emotional skills which are the cornerstone to teaching as happiness teacher training. This training would aim both at offering the opportunity to experience positive psychology interventions and developing teachers’ reflexive skills. Gratitude practices, emotional regulation interventions, recognition and use of character strengths are levers that act both on intra- and interpersonal relationships. (shrink)

We propose Edgar Morin’s notion of transdisciplinarity as a complementary educational perspective for preparing business school students in addressing the complex global socio-economic and environmental challenges that our planet has been facing for some time. Morin’s notion of transdisciplinarity spans various disciplines, both within disciplines and beyond individual disciplines. Morin’s transdisciplinary approach is inquiry driven and presents a systemic/humanistic vision and form of awareness that challenges habitually dualistic and simplistic thinking. Morin’s transdisciplinarity is based on a dialogical and translogical (...) principle that extends classical and rigid logic and that helps students to explore and unify concepts of a simultaneous complementary and contradictory nature. Confronting students with different modes of thinking, imagining and feeling can help them to develop greater self-awareness, critical reflection, and creativity; with various frames of reference; and with an openness toward and confidence in engaging in changes needed to address global challenges in a sustainable and responsible way.
