We define a model for computing probabilities of right-nested conditionals in terms of graphs representing Markov chains. This is an extension of the model for simple conditionals from Wójtowicz and Wójtowicz. The model makes it possible to give a formal yet simple description of different interpretations of right-nested conditionals and to compute their probabilities in a mathematically rigorous way. In this study we focus on the problem of the probabilities of conditionals; we do not discuss questions concerning logical and metalogical (...) issues such as setting up an axiomatic framework, inference rules, defining semantics, proving completeness, soundness etc. Our theory is motivated by the possible-worlds approach ; however, our model is generally more flexible. In the paper we focus on right-nested conditionals, discussing them in detail. The graph model makes it possible to account in a unified way for both shallow and deep interpretations of right-nested conditionals. In particular, we discuss the status of the Import-Export Principle and PCCP. We briefly discuss some methodological constraints on admissible models and analyze our model with respect to them. The study also illustrates the general problem of finding formal explications of philosophically important notions and applying mathematical methods in analyzing philosophical issues. (shrink)

I examine what I shall call meta-philosophy: a philosophical examination into what philosophy is, can be, should be, something of what it has been, what the point (if any) of it is and what, if anything, it can contribute to our understanding of and the making sense of our lives, including our lives individually and together, and of the social order in which we live.

It is important to design digital infrastructure that can better accommodate multicultural and pluralistic views from its foundations. It is insufficient to look at only the responses and influences of culture on technology without considering how the technology can be adapted in anticipation of, and to support, pluralistic multicultural perspectives in its original design. This goes beyond the simple act of supporting multiple languages and interfaces, but should include the ability of digital and data infrastructure to capture and accommodate pluralistic (...) views, supporting multiple perspectives in the representation and processing of the data itself. In this work, we look at how rethinking the representation of data can allow us to more directly tackle domains that are typically hampered due to intercultural differences, and their inevitable losses in translation, particularly losses of valuable information like context and intention. When we refer to a loss of context and intention, we are referring to the loss of semantic information when practices such as referencing and citation are hard-coded to a particular set of cultural norms. We show that it is possible to expand the way in which we track referential data to capture richer semantic information regarding the contexts and intentions of the creators of this data, and thereby better serve the varied needs of those who consume, study, and refer to such data. We demonstrate this concept through a prototype system for a multicultural digital infrastructure, which we have namedMultiVerse, and discuss its ethical implications from the perspectives of ‘multistability’, Intercultural Information Ethics framework, and poststructuralism.

Social dilemmas, in which individually selfish behavior leads to collectively deficient outcomes, continue to be an important topic of research because of their ubiquity. The present research with Japanese participants replicates, with slight modifications, public goods games previously run in the United States. In contrast to recent work showing profound cross-cultural differences, the results of two studies reported here show remarkable cross-cultural similarities. Specifically, results suggest that (1) as in the U.S., allowing incremental commitment to a public good is effective (...) at eliciting contributions, (2) individual differences in trust affect contributions, (3) the distribution of player types in the U.S. and Japan are very similar, and (4) the dynamics of play in the public goods games used here are strikingly parallel. These results are discussed in the context of the relationship between cross-cultural differences and economic institutional environments. (shrink)

A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, even when it would be impersonally better for others to bear these costs.

Kuhn’s “essential tension” between conservative and innovative imperatives in enquiry has an empirical analogue—between the potential benefits of collectivization of enquiry and the social dynamic impediments to effective sharing of information and insights in collective settings. A range of empirical materials from social psychology and organization theory are considered which bear on the issue of balancing these opposing forces and an institution is described in which they are balanced in a way which is appropriate for collective knowledge production.

Using information on students’ past participation in economic experiments, we analyze whether behavior in public goods games is affected by experience and history. We find that: on average, the amount subjects contribute and expect others to contribute decreases with experience; at the individual level, the proportion of unconditional cooperators decreases with experience, while the proportion of selfish people increases. Finally, history influences behavior less than experience. Researchers are urged to control for subjects’ experience and history to improve the external validity (...) and replicability of results.

Opponents of ceteris paribus laws are apt to complain that the laws are vague and untestable. Indeed, claims to this effect are made by Earman, Roberts and Smith in this volume. I argue that these kinds of claims rely on too narrow a view about what kinds of concepts we can and do regularly use in successful sciences and on too optimistic a view about the extent of application of even our most successful non-ceteris paribus laws. When it comes to (...) testing, we test ceteris paribus laws in exactly the same way that we test laws without the ceteris paribus antecedent. But at least when the ceteris paribus antecedent is there we have an explicit acknowledgment of important procedures we must take in the design of the experiments — i.e., procedures to control for “all interferences” even those we cannot identify under the concepts of any known theory.

Recording of neural activity during grasping actions in macaques showed that grasp-related sensorimotor transformations are accomplished in a circuit constituted by the anterior part of the intraparietal sulcus (AIP), the ventral (F5) and the dorsal (F2) region of the premotor area. In humans, neuroimaging studies have revealed the existence of a similar circuit, involving the putative homolog of macaque areas AIP, F5, and F2. These studies have mainly considered grasping movements performed with the right dominant hand and only a few (...) studies have measured brain activity associated with a movement performed with the left non-dominant hand. As a consequence of this gap, how the brain controls for grasping movement performed with the dominant and the non-dominant hand still represents an open question. A functional magnetic resonance imaging (fMRI) experiment has been conducted, and effective connectivity (dynamic causal modeling, DCM) was used to assess how connectivity among grasping-related areas is modulated by hand (i.e., left and right) during the execution of grasping movements toward a small object requiring precision grasping. Results underlined boosted inter-hemispheric couplings between dorsal premotor cortices during the execution of movements performed with the left rather than the right dominant hand. More specifically, they suggest that the dorsal premotor cortices may play a fundamental role in monitoring the configuration of fingers when grasping movements are performed by either the right and the left hand. This role becomes particularly evident when the hand less-skilled (i.e., the left hand) to perform such action is utilized. The results are discussed in light of recent theories put forward to explain how parieto-frontal connectivity is modulated by the execution of prehensile movements. (shrink)

Many of the world's problems--severe poverty and starvation, global warming, religious war, oppressive and tyrannical regimes--are large, well beyond what any ordinary person might have a significant impact upon. We are at most in a position to make small contributions. This fact is behind a seductive argument: there is nothing we can do about the large problems; since we cannot do anything about the large problems, it is not true that we ought to do anything; therefore, we can, in good (...) conscience, decline to contribute. There may be something to this argument, but we should not make too much of it. What I shall argue is that much depends on the details, that sometimes small contributions, even when there is little prospect of solving the large problem, may be warranted. Worries about the smallness of our contribution do not undermine all reasons for making the small contributions. (shrink)

This text intends on putting what may be called a philosophy of marronage1 in conversation with Indigenous thought, particularly by engaging with the thought of Cherokee Nation philosopher Brian Burkhart from his essay “Locality is a Metaphysical Fact.”2 While the topic is treated in detail in Burkhart’s Indigenizing Philosophy through the Land (2019), my engagement with that specific text will be reserved for a separate project. What is of interest to me here is Burkhart’s elaboration of the concept of locality, (...) which refers to an “ontological kinship with the land” that serves as a bulwark against the sedimentation of the coloniality of being in the ontology of the Indigenous subject. I would like to add some nuance to it from the positionality of a subject whose ontological kinship with the land was severed through the kidnapping and enslavement of the ancestors from the African continent. In the process, my intent is to offer an alternate reading of Frantz Fanon (1925–1961) which may allow Fanonian thought to be reconciled with North Native American Indigenous thought, which has typically rejected Fanon’s rejection of a return to ancestral ways. This alternate reading of Fanon shows that a reconnection with ancestral ways, and reconstruction of locality, constitutes only part of the liberation project for Afro-diasporic subjects. (shrink)
