In ”Skepticism,” Peter Klein distinguishes between the “Academic Skeptic” who proposes that we cannot have knowledge of a certain set of propositions and the “Pyrrhonian Skeptic” who refrains from opining about whether we can have knowledge. Klein argues that Academic Skepticism is plausibly supported by a “Closure Principle‐style” argument based on the claim that if x entails y and S has justification for x, then S has justification for y. He turns to contextualism to see if it can (...) contribute to the discussion between one who claims that we can have knowledge about some epistemically interesting class of propositions and the Academic Skeptic. He outlines the background of Pyrrhonian Skepticism, pointing out that the Pyrrhonist withholds assent concerning our knowledge‐bearing status because reason cannot provide an adequate basis for assent. He assesses three possible patterns of reasoning, and concludes that the Pyrrhonist view, that reason cannot resolve matters concerning the nonevident, is vindicated. (shrink)

This book is the most comprehensive and rigourous critique of the ways disciplinary boundaries still inhibit knowledge-production and integration.

The epistemic position of an agent often depends on their position in a larger network of other agents who provide them with information. In general, agents are better off if they have diverse and independent sources. Sullivan et al. [19] developed a method for quantitatively characterizing the epistemic position of individuals in a network that takes into account both diversity and independence; and presented a proof-of-concept, closed-source implementation on a small graph derived from Twitter data [19]. This paper reports on (...) an open-source reimplementation of their algorithm in Python, optimized to be usable on much larger networks. In addition to the algorithm and package, we also show the ability to scale up our package to large synthetic social network graph profiling, and finally demonstrate its utility in analyzing real-world empirical evidence of ‘echo chambers’ on online social media, as well as evidence of interdisciplinary diversity in an academic communications network.

Neural engineers and clinicians are starting to translate advances in electrodes, neural computation, and signal processing into clinically useful devices to allow control of wheelchairs, spellers, prostheses, and other devices. In the process, large amounts of brain data are being generated from participants, including intracortical, subdural and extracranial sources. Brain data is a vital resource for BCI research but there are concerns about whether the collection and use of this data generates risk to privacy. Further, the nature of BCI research (...) involves understanding and making inferences about device users’ mental states, thoughts, and intentions. This, too, raises privacy concerns by providing otherwise unavailable direct or privileged access to individuals mental lives. And BCI-controlled prostheses may change the way clinical care is provided and the type of physical access caregivers have to patients. This, too, has important privacy implications. I In this chapter we examine several of these privacy concerns in light of prominent views of the nature and value of privacy. We argue that increased scrutiny needs to be paid to privacy concerns arising from Big Data and decoding of mental states, but that BCI research may also provide opportunity for individuals to enhance their privacy.

This text collects Melaine Klein's writings from 1946 until her death in 1960, including two papers published posthumously. This was her last major work which introduces her theory of primary envy.

In this chapter, I investigate the metaphysical assumptions that medieval thinkers considered necessary in order to integrate the vegetative powers and processes into their conception of human beings as composed of a material body and an immaterial soul. My aim is to show that vegetative powers and processes are central to the late medieval debate on faculty psychology and on the unity or plurality of substantial forms. The chapter has two parts. First, I present three different accounts of the ontological (...) status of the vegetative powers in relation to the body and the soul, as found in Thomas Aquinas, William of Ockham, and John Buridan. All three maintain that the vegetative powers belong to the soul but disagree as to whether they are identical with it or somehow distinct from it, especially when the soul in question is immaterial. Second, I investigate how medieval thinkers accounted for the metaphysics behind the operations of the vegetative powers in human beings, who are endowed with immaterial souls, in particular when it comes to procreation and digestion. A pressing problem for the vegetative powers of human beings is how they can produce a new substance when this composite is supposed to include an immaterial soul which is not naturally generated. Regarding procreation, one can distinguish two different approaches: dispositional generation of material conditions and substantial generation of the body. A similar problem for human beings arises in nutrition and growth once this process is taken to be some kind of substantial change, namely, the corruption of food and the production of new parts of the living being. Two accounts can be distinguished: “transmateriation” of the matter of food into the nourished body and generation of parts of the body. (shrink)

Métachronologie propose une théorie du temps entièrement nouvelle, temps comportant non pas une, mais deux dimensions. Cette théorie se développe à partir de l'analyse d'un instant, lui-même conçu comme double et non simple : instant composé de deux temps coordonnés, passé et futur, chacun mobilisé par sa manière propre de se temporaliser. Au coeur de l'instant, non son présent mais sa faille, un vide de temps. La métachronologie est la métaphysique de ce temps sans présent, auquel se substitue l'instance d'une (...) collision entre deux temporalités corrélatives. La collision est une notion employée par Vladimir Jankélévitch pour désigner la logique (qu'il nomme "métalogique") d'un renvoi réciproque et infini d'un terme à l'autre d'une alternative. Son modèle en est l'instant de la mort, collision de la pensée avec ce qui l'enlève et qu'elle ne rencontre pas. La métachronologie se donne à poursuivre cette intuition métalogique de Jankélévitch, cela jusqu'en des conséquences surprenantes, en rupture même avec quelques racines de sa propre philosophie du temps. La fidélité à sa pensée supposant qu'on en écoute ce qu'elle porte d'inouï. Tout instant donc serait collisionnel. Au lieu du présent, sa défaillance, sorte de trou où passé et futur s'excluent et pourtant se coordonnent, et se convertissent l'un en l'autre. Aussi cette collision est-elle ici notée "vav", opérateur en hébreu de conjonction de termes et de conversion de temps. Quant à l'écartement d'un même instant en deux temps distincts, il qualifie la quandoquité de cet instant, par analogie avec l'ubiquité d'un événement présent au même instant en deux lieux séparés. Ainsi principe de rupture, de coordination et de conversion, "vav" se dispose pour reformuler le mystère temporel en s'arrêtant à cette seule énigme : une sorte de néant écartant en l'instant même deux temps indissociables et incompatibles.

This is the third draft of a paper that aims to clarify the apparent contradictions in the views presented in certain standards and other specifications of health informatics systems, contradictions which come to light when the latter are evaluated from the perspective of realist philosophy. One of the origins of this document was Klein’s discussion paper of 2005-07-02 entitled “Conceptology vs Reality” and the responses from Smith, as well as the several hours of discussions during the 2005 MIE meeting (...) in Geneva.

One of the important lessons to take away from Rohit Parikh’s impressive body of work is that logicians and computer scientists have much to gain by focusing their attention on the intricacies of political campaigns. Drawing on recent work developing a theory of expressive voting, we study the dynamics of voters’ opinions during an election. In this paper, we develop a model in which the relative importance of the different issues that concern a voter may change either in response to (...) candidates’ statements during a campaign or due to unforeseen events. We study how changes in a voter?s attention to the issues influence voting behavior under voting systems such as plurality rule and approval voting. We argue that it can be worthwhile for candidates to reshape public focus, but that doing so can be a complex and risky activity. (shrink)

In this paper I argue that much of the confusion and mystery surrounding the concept of "self" can be traced to a failure to appreciate the distinction between the self as a collection of diverse neural components that provide us with our beliefs, memories, desires, personality, emotions, etc (the epistemological self) and the self that is best conceived as subjective, unified awareness, a point of view in the first person (ontological self). While the former can, and indeed has, been extensively (...) studied by researchers of various disciplines in the human sciences, the latter most often has been ignored -- treated more as a place holder attached to a particular predicate of interest (e.g., concept, reference, deception, esteem, image, regulation, etc). These two aspects of the self, I contend, are not reducible -- one being an object (the epistemological self) and the other a subject (the ontological self). Until we appreciate the difficulties of applying scientific methods and analysis to what cannot be reduced to an object of inquiry without stripping it of its essential aspect (its status as subject), progress on the "self", taken as a pluralistic construct, will continue to address only one part of the problems we face in understanding this most fundamental aspect of human experience.

The Meno, one of the most widely read of the Platonic dialogues, is seen afresh in this original interpretation that explores the dialogue as a theatrical presentation. Just as Socrates's listeners would have questioned and examined their own thinking in response to the presentation, so, Klein shows, should modern readers become involved in the drama of the dialogue. Klein offers a line-by-line commentary on the text of the Meno itself that animates the characters and conversation and carefully probes (...) each significant turn of the argument. "A major addition to the literature on the Meno and necessary reading for every student of the dialogue."--Alexander Seasonske, Philosophical Review "There exists no other commentary on Meno which is so thorough, sound, and enlightening."-- Choice Jacob Klein was a student of Martin Heidegger and a tutor at St. John's College from 1937 until his death. His other works include Plato's Trilogy: Theaetetus, the Sophist, and the Statesman, also published by the University of Chicago Press. (shrink)
