Affordances are possibilities for action offered by the environment. Recent research on affordances holds that there are differences in how people experience such possibilities for action. However, these differences have not been properly investigated. In this paper I start by briefly scrutinizing the existing literature on this issue, and then argue for two claims. First, that whether an affordance solicits action or not depends on its relevance to the agent’s concerns. Second, that the experiential character of how an affordance solicits (...) action depends on the character of the concern to which it is relevant. Concerns are conceived of as bodily forms of responsiveness, and solicitations are experienced through this responsiveness. The main aim of this paper is to make clear that an understanding of experiential differences in solicitations has to be based on a phenomenological appreciation of how one experiences one’s responsiveness to those solicitations. In the remainder of the paper I show how such a phenomenological appreciation reveals several characteristics of our responsiveness and I briefly explore three of them: valence, force and mineness. In the final section I discuss the self-referentiality of affordances in light of the current proposal, and argue that this self-referentiality is broader than is typically acknowledged. (shrink)

A Brief History of the Paradox is the first narrative history of paradoxes. Sorenson draws us deep inside the tangles of riddles, paradoxes and conundrums by answering the questions which are seemingly unanswerable. Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Filled with illuminating anecdotes, A Brief History of the Paradox is vividly written and will appeal to anyone who finds trying to answer unanswerable (...) questions a paradoxically pleasant endeavour.

A number of authors have argued that Peano Arithmetic supplemented with a logical validity predicate is inconsistent in much the same manner as is PA supplemented with an unrestricted truth predicate. In this paper I show that, on the contrary, there is no genuine paradox of logical validity—a completely general logical validity predicate can be coherently added to PA, and the resulting system is consistent. In addition, this observation lead to a number of novel, and important, insights into the nature (...) of logical validity itself. (shrink)

Episodic memories can no longer be seen as the re-activation of stored experiences but are the product of an intense construction process based on a memory trace. Episodic recall is a result of a process of scenario construction. If one accepts this generative framework of episodic memory, there is still a be big gap in understanding the role of the narrative self in shaping scenario construction. Some philosophers are in principle sceptic by claiming that a narrative self cannot be more (...) than a causally inefficacious attributed entity anyway. Thus, we first characterize a narrative self in detail and second we clarify its influential causal role in shaping our episodic memories by influencing the process of scenario construction. This happens at three stages, namely at the level of the input, the output and the process of scenario construction. (shrink)

This article argues for engaging with the smart city as a sociotechnical imaginary. By conducting a close reading of primary source material produced by the companies IBM and Cisco over a decade of work on smart urbanism, we argue that the smart city imaginary is premised in a particular narrative about urban crises and technological salvation. This narrative serves three main purposes: it fits different ideas and initiatives into a coherent view of smart urbanism, it sells and disseminates this version (...) of smartness, and it crowds out alternative visions and corresponding arrangements of smart urbanism. Furthermore, we argue that IBM and Cisco construct smart urbanism as both a reactionary and visionary force, plotting a model of the near future, but one that largely reflects and reinforces existing sociopolitical systems. We conclude by suggesting that breaking IBM’s and Cisco’s discursive dominance over the smart city imaginary requires us to reimagine what smart urbanism means and create counter-narratives that open up space for alternative values, designs, and models.

You face two buttons. Pushing one will destroy Greensboro. Pushing the other will save it. There is no way for you to know which button saves and which destroys. What ought you to do? Answer: You ought to make the correct guess and push the button that saves Greensboro. Second question: Do you have an obligation to push the correct button?

This chapter summarizes research on free will. Progress has been made by discarding outmoded philosophical notions in favor of exploring how ordinary people understand and use the notion of free will. The concept of responsible autonomy captures many aspects of layperson concepts of free will, including acting on one's own (i.e., not driven by external forces), choosing, using reasons and personal values, conscious reflection, and knowing and accepting consequences and moral implications. Free will can thus be understood as form of (...) volition (action control) that evolved to enable people to live in cultural societies. Much work has shown that belief in free will (as opposed to disbelief) is associated with actions that are conducive to functioning well in culture, including helpfulness, restraint of aggression, learning via counterfactual analysis, thinking for oneself, effective job performance, and appropriate gratitude. Belief in free will increases in response to misdeeds by others, thus emphasizing the link to personal responsibility. Research on volition indicates that self-regulation, intelligent reasoning, decision making, and initiative all deplete a (common) limited energy source, akin to the folk notion of willpower and linked to the body's glucose supplies. Free will is thus not an absolute or constant property of persons but a variable, fluctuating capability—one that is nonetheless highly adaptive for individuals and society. -/- The notion that people have free will has been invoked in multiple contexts. Legally and morally, it explains why people can be held responsible for their actions. Theologically, it was used to explain why a supposedly kind and omniscient god would send most of the people he created to hell (Walker, 1964). Yet, for such an important concept, there remains wide-ranging disagreement and confusion over its existence and its nature. For example, philosophers still debate whether humans truly have free will and, if so, under what conditions human volition deserves to be considered free (Kane, 2011). In psychology, most theorists believe that humans engage in self-control, rational choice, planning, initiative, and related acts of volition. The debate is not whether these things occur but merely whether these should be called free will. -/- This chapter will provide an overview of recent psychology experiments concerned with free will. There are three main and quite distinct sets of problems, each with associated lines of research. The first is concerned with how people understand the idea of free will. The second concerns the causes and consequences of believing in free will. The third focuses on the actual volitional processes that guide human action. (shrink)

The argument proceeds by exploiting the gradually decreasing vagueness of a certain sequence of predicates. the vagueness of 'vague' is then used to show that the thesis that all vague predicates are incoherent is self-defeating. a second casualty is the view that the probems of vagueness can be avoided by restricting the scope of logic to nonvague predicates.

There is thought to be a rich connection between the self and the phenomenology of episodic memory. Despite the emphasis on this link, the precise relation between the two has been underexplored. In fact, even though it is increasingly acknowledged that there are various facets of the self, this notion of the multifaceted self has played very little role in theorizing about the phenomenology of episodic memory. Getting clear about the complex phenomenology of episodic memory involves getting clear about various (...) components that contribute to the sense of self. Inspired by work on 4E cognition, and focusing on the phenomenological feature of felt connections, we show that the phenomenology of episodic memory can be modulated by focusing on different facets — embodied, extended, embedded, and ecological — of the self.

Some people believe more than others in free will, and researchers have both measured and manipulated those beliefs. Disbelief in free will has been shown to cause dishonest, selfish, aggressive, and conforming behavior, and to reduce helpfulness, learning from one’s misdeeds, thinking for oneself, recycling, expectations for occupational success, and actual quality of performance on the job. Belief in free will has been shown to have only modest or negligible correlations with other variables, indicating that it is a distinct trait. (...) Belief in free will has correlated positively with life satisfaction and finding life meaningful, with self‐efficacy and self‐control, with low levels of stress, and (though not entirely consistently) with internal locus of control. High belief in free will has been linked to a punitive attitude toward wrongdoers and lower forgiveness toward them. The belief seems to involve a sense of agency and expecting others to behave in morally responsible fashion. (shrink)

This chapter examines the debate between advocates of classical logic and advocates of intuitionistic logic. It examines the semantic and epistemic issues on which this debate is usually conducted. After introducing the idea that logic is a model of correct reasoning, the chapter explores the viability of a logic intermediate between classical and intuitionistic.

Introduction In many ways this book is a kind of detective story. It tries to find something out about the kind of society which is taking shape in these ...

Michael Dummett argues that acceptance of potentially infinite collections requires that we abandon classical logic and restrict ourselves to intuitionistic logic. In this paper we examine whether Dummett is correct. After developing two detailed accounts of what, exactly, it means for a concept to be potentially infinite (based on ideas due to Charles McCarty and Øystein Linnebo, respectively), we construct a Kripke structure that contains a natural number structure that satisfies both accounts. This model supports a logic much stronger than (...) intuitionistic logic, demonstrating that Dummett was wrong. We conclude by briefly examining ways to extend the account(s) in question to indefinitely extensible concepts such as Cardinal, Ordinal, and Set. (shrink)

Would personal immortality have any value for one so endowed? An affirmative answer would seem so obvious to some that they might be tempted to go so far as to claim that immortality is a condition of life's having any value at all. The claim that immortality is a necessary condition for the meaningfulness of life seems untenable. What, however, of the claim that immortality is a sufficient condition for the meaningfulness of life? Though some might hold this to be (...) the characteristic religious view, this is certainly disputable. Thus McTaggart reminds us, for instance, that ‘Buddhism... holds immortality to be the natural state of man, from which only the most perfect can escape.’ I want to argue that we can imagine variants of personal immortality which would not be valuable and hence immortality in itself cannot be a sufficient condition for value. What is required for the meaningfulness of life is that life exhibit certain valuable qualities. But then the endless exhibition of these qualities is not only unnecessary for the meaningfulness of life, but the endlessness of a life can even devalue those qualities that would make valuable a single, bounded life.

Todd’s quip absurdly implies he knew that 30 carats is the threshold for vulgarity. But most philosophers think stopping here misses the root of the joke. They think there is a more fundamental absurdity; that it is even possible for a single carat to make the difference between a vulgar ring and a non-vulgar ring. We epistemicists defend the possibility.

In recent years, the sharing economy has attracted considerable attention, both scholarly and popular, relating to its capacity to enforce or undermine extant economic conventions. However, the process through which technological developments can effectively have this outcome of altering extant conventions on what is morally acceptable or desirable is still unclear. In this paper, we draw on the work of Boltanski and Thévenot and the notion of agencement to investigate the moral and performative dimension of controversies related to the SE. (...) The research stems from a qualitative case-based study of the controversy following Uber’s implementation in Montréal’s taxi market. We contribute to the literature on the SE through an empirical study of the moral debates entailed in the unfolding in situ of a SE device. We also add to the literature using the ‘Orders of Worth’ framework by showing how a compromise is solidified. We find that beyond discursive strategies, it is the concrete recomposition of laws, conventions, devices, persons, etc. that harmonised different definitions of the common good. Finally, we contribute to the literature on the relationship between technology, ethics, and social change by capturing the specific values that legitimise Uber, and by following their unfolding throughout a controversy.

In this essay I defend both the individual plausibility and conjoint consistency of two theses. One is the Intentionality Thesis: that all mental states are intentional . The other is the Self-Awareness Thesis: that if a subject is aware of an object, then the subject is also aware of being aware of that object. I begin by arguing for the individual prima facie plausibility of both theses. I then go on to consider a regress argument to the effect that the (...) two theses are incompatible. I discuss three responses to that argument, and defend one of them. (shrink)

This note opens with brief evaluations of classical foundationalist endeavors – those of Frege, Russell, Brouwer and Hilbert. From there we proceed to some pluralist approaches to foundations, focusing on Putnam and Wittgenstein, making a note of what enables their pluralism. Then, I bring up approaches that find foundations potentially harmful, as expressed by Rav and Lakatos. I conclude with a brief discussion of a late medieval Indian case study in order to show what an “unfounded” mathematics could look like. (...) The general purpose is to re-evaluate the desiderata of foundational programs in mathematics. (shrink)

One familiar philosophical use of the term ‘evil’ just contrasts it with ‘good’, i.e., something is an evil if it is a bad thing, one of life’s “minuses.” This is the sense of ‘evil’ that is used in posing the traditional theological problem of evil, though it is customary there to distinguish between moral evils and natural evils. Moral evils are those bad things that are caused by moral agents; natural evils are those bad things that are not caused by (...) moral agents. Since the existence of evils of both sorts is usually taken to be indubitable, the problem of evil is then construed as the problem of how to square their existence with the existence of an all-powerful and benevolent God.

The vanishing point is a representational gap that organizes the visual field. Study of this singularity revolutionized art in the fifteenth century. Further reflection on the vanishing point invites the conjecture that the self is an absence. This paper opens with perceptual peculiarities of the vanishing point and closes with the metaphysics of personal identity.

What do you get when you cross a fallacy with a good argument? A fugu, that is, a valid argument that tempts you to reach its conclusion invalidly. You have yielded to the temptation more than you realize. If you are a teacher, you may have served many fugus. They arise systematically through several mechanisms. Fugus are interesting intermediate cases that shed light on the following issues: bare evidentialism, false pleasure, philosophy of education, and the ethics of argument. Normally, a (...) fugu will not yield knowledge from known premises. But if the reasoning is only slightly fallacious, they do yield knowledge. These mild fugus show that we can gain knowledge by invalid reasoning. This is a conservative resource for historians. They want to credit discoveries to Euclid rather than those who made minor corrections to his proofs, such as David Hilbert. We also benefit from this practice of grandfathering in old standards of knowledge attribution. For we can compete spiritedly for priority. We do not need to worry that credit will instead go to future scholars who will make the minor amendments needed to raise present proofs to a future standard of demonstration. (shrink)

Creationists believe that C. K. Chesterton created Father Brown in his detective stories. Since creating implies a creation, Father Brown exists. Atheists object that the same reasoning could prove the existence of God. But creationists such as Jonathan Schaffer insist atheists do believe that God exists. Serious metaphysics rarely concerns existence. The disagreement between the theist and the atheist is about the nature of God, not His existence. Schaffer underestimates the religious imagination. There could be a religion that explicitly regarded (...) God as a fictional character. The tenets of this, presently hypothetical, religion are developed in a dialogue. (shrink)

It is sometimes suggested that impure sets are spatially co-located with their members (and hence are located in space). Sets, however, are in important respects like numbers. In particular, sets are connected to concepts in much the same manner as numbers are connected to concepts—in both cases, they are fundamentally abstracts of (or corresponding to) concepts. This parallel between the structure of sets and the structure of numbers suggests that the metaphysics of sets and the metaphysics of numbers should parallel (...) each other in relevant ways. This entails, in turn, that impure sets are not co-located with their members (nor are they located in space). (shrink)

The poster boy for my paper is the King's Messenger in Lewis Carroll's Through the Looking Glass. Recall that since the White Queen lives backwards, her memory works forwards. She pities Alice who can only remember things after they happen. Alice asks which things the Queen remembers best: `Oh, things that happened the week after next,' the Queen replied in a careless tone. `For instance, . . . there's the King's Messenger. He's in prison now, being punished: and the trial (...) doesn't even begin till next Wednesday: and of course the crime comes last of all.' (Chapter V) Is the King's Messenger being treated unjustly? Why not prepunish people for their future crimes? True, it is generally easier to have knowledge about past crimes than future crimes. But is unpredictability the only problem with prepunishment?
