This dissertation presents a theory of online propaganda and radicalization which highlights the interaction between communication, epistemology, and technology. The central focus is providing an analysis of online media communications, content posted on social media platforms and transmitted by automated recommendation systems, which better explains how propaganda and radicalization have adapted so well to this technological environment. First, propaganda is interpreted as a unique approach to communication which manipulates the expectations an audience has of successful communications, and not simply as (...) a collection of individual acts with characteristic properties. A major aspect to this interpretation of propaganda is an emphasis on those environmental factors and sociological conditions involved in communication, which can have a direct impact on our experience and interpretation of reality. Second, considering these aspects a detailed account of how users experience the technical machinery facilitating social media platforms is presented, highlighting the problematic epistemic states users are forced to inhabit. Finally, online radicalization is explained through this new propaganda interpretation, the user experience of the technology underpinning social media platforms, and the epistemic states forced by online automation.

In this paper we compare the propositional logic of Frege’s Grundgesetze der Arithmetik to modern propositional systems, and show that Frege does not have a separable propositional logic, definable in terms of primitives of Grundgesetze, that corresponds to modern formulations of the logic of “not”, “and”, “or”, and “if…then…”. Along the way we prove a number of novel results about the system of propositional logic found in Grundgesetze, and the broader system obtained by including identity. In particular, we show that (...) the propositional connectives that are definable in terms of Frege’s horizontal, negation, and conditional are exactly the connectives that fuse with the horizontal, and we show that the logical operators that are definable in terms of the horizontal, negation, the conditional, and identity are exactly the operators that are invariant with respect to permutations on the domain that leave the truth-values fixed. We conclude with some general observations regarding how Frege understood his logic, and how this understanding differs from modern views. (shrink)

We agree with Barsalou's claim about the importance of perceptual symbols in a theory of abstract concepts. Yet we maintain that the richness of many abstract concepts arises from the metaphorical mapping of recurring patterns of perceptual, embodied experience to provide essential structure to these abstract ideas.

The United States, along with other nations and international organizations, has developed an elaborate system of ethical norms and legal rules to govern biomedical research using human subjects. These policies govern research that might provide direct health benefits to participants and research in which there is no prospect for participant health benefits. There has been little discussion, however, about how well these rules would apply to research designed to improve participants’ capabilities or characteristics beyond the goal of good health. When (...) mentioned at all in the literature, this so-called enhancement research, as opposed to research aimed at diagnosing, preventing, curing, or treating illnesses or medical conditions, is usually dismissed without explanation.

In the Preface to his impressive and engaging new commentary on the Critique of Pure Reason, Jay Rosenberg informs us that the book is both a product of his own lectures and a “direct descendent of Wilfrid Sellars’ legendary introduction to Kant” . Its origins in the classroom give Accessing Kant a refreshingly pedagogical tone. Throughout, Rosen-berg—who was a student of Sellars’ at the University of Pittsburgh—makes felicitous use of clear examples, familiar problems and authors, and visual aids to (...) clarify “the Big Picture” operating in the first Critique. Mercifully, however, his style owes little to Sellars’ own brutally opaque prose.Rosenberg also shares his teacher’s enthusiasm for the history of philosophy. The reader will not find Rosenberg sloughing off Kant’s “lesser predecessors” in the manner of P. F. Strawson. However, the history on display in Accessing Kant has more to do with the curricular demands of English-speaking philosophy departments than with Kant’s own intellectual and cultural context. This means that his Kant argues across the ages with giants rather than with his peers in Halle and Berlin. Nor, despite the occasional reference to Kant’s handwritten marginalia, does Rosenberg devote any effort to. (shrink)

People are biased toward beliefs that are welcomed by their in-group. Some beliefs produced by these biases—such as climate change denial and religious belief—can be fruitfully modeled by signaling theory. The idea is that the beliefs function so as to be detected by others and manipulate their behavior, primarily for the benefits that accrue from favorable tribal self-presentation. Signaling theory can explain the etiology, distinctive form, proper function, and alterability of these beliefs.

Opponents of abortion sometimes hold that it is impermissible because fetuses are persons from the moment of conception. But miscarriage, which ends up to 89 % of pregnancies, is much deadlier than abortion. That means that if opponents of abortion are right, then miscarriage is the biggest public-health crisis of our time. Yet they pay hardly any attention to miscarriage, especially very early miscarriage. Attempts to resolve this inconsistency by adverting to the distinction between killing and letting die or to (...) the difficulty of preventing miscarriage fail, leaving a dilemma. Opponents of abortion should either advocate a substantial shift in our political and medical priorities or else give up the view that fetuses are persons from the moment of conception. (shrink)

The theory and practice of history and its relevance to the modern world, by Britains greatest radical historian.

Recently, Doolittle and Inkpen formulated a thought provoking theory, asserting that evolution by natural selection was responsible for the sideways evolution of two radically different kinds of selective units (also called Domains). The former entities, termed singers, correspond to the usual objects studied by evolutionary biologists (gene, genomes, individuals, species, etc.), whereas the later, termed songs, correspond to re‐produced biological and ecosystemic functions, processes, information, and memes. Singers perform songs through selected patterns of interactions, meaning that a wealth of critical (...) phenomena might receive novel evolutionary explanations. However, this theory did not provide an empirical approach to study evolution in such a broadened context. Here, we show that analyzing songs and singers, using patterns of interaction networks as a common ontology for both, offers a novel, actionable, inclusive and mathematical way to analyze not only the re‐production but also the evolution and fitness of biological and ecosystemic interconnected processes.

This paper explains Sophie de Grouchy’s philosophical debts to Adam Smith. I have three main reasons for this: first, it should explain why eighteenth-century philosophical feminists found Smith, who has—to put it mildly—not been a focus of much recent feminist admiration, a congenial starting point for their own thinking; second, it illuminates De Grouchy’s considerable philosophical originality, especially her important, overlooked contributions to political theory; third, it is designed to remove some unfortunate misconceptions that have found their way into Karin (...) Brown’s ‘Introduction’ to the recent and much-to-be-welcomed translation of Sophie de Grouchy’s Lettres Sur La Sympathie. While Brown claims that there are major ‘differences’ in their programs of ‘social reform’, I argue there are important commonalities between Smith and De Grouchy. In particular, I highlight how they share a common understanding of how human sensibilities are shaped by social institutions and I show that De Grouchy’s path-breaking analysis of negative and positive liberty is grounded in her extension of Smith’s political theory and moral psychology.

Differing views on reduction are briefly reviewed and a suggestion is made for a working definition of 'approximate reduction'. Ab initio studies in quantum chemistry are then considered, including the issues of convergence and error bounds. This includes an examination of the classic studies on CH2 and the recent work on the Si2C molecule. I conclude that chemistry has not even been approximately reduced.

Trust me: my chair isn't big enough for two. You may doubt that every rational, conscious being is a person; perhaps there are beings that mistakenly believe themselves to be people. If so, read ‘rational, conscious being’ or the like for 'person'.

The prosaic content of these sayings is that events change from future to present and from present to past. Your next birthday is in the future, but with the passage of time it draws nearer and nearer until it is present. 24 hours later it will be in the past, and then lapse forever deeper into history. And things get older: even if they don’t wear out or lose their hair or change in any other way, their chronological age is (...) always increasing. These changes are universal and inescapable: no event could ever fail to be first future, then present, then past, and no persisting thing can avoid growing older. We call this process time’s passage. (shrink)

This study explores several arguments against Spinoza's philosophy that were developed by Henry More, Samuel Clarke, and Colin Maclaurin. In the arguments on which I focus, More, Clarke, and Maclaurin aim to establish the existence of an immaterial and intelligent God precisely by showing that Spinoza does not have the resources to adequately explain the origin of motion. Attending to these criticisms grants us a deeper appreciation for how the authority derived from the empirical success of Newton's enterprise was used (...) to settle debates within philosophy. What I emphasize is that in the progression from More to Clarke to Maclaurin, key Newtonian concepts from the Principia (1687), such as motion, atomism, and the vacuum, are introduced and exploited in order to challenge the account of matter and motion that is presented in Spinoza's Ethics (1677). Building on this treatment, I use the arguments from More and Clarke especially to help discern the anti-Spinozism that can be detected in Newton's General Scholium (1713). Ultimately, the Newtonian criticisms that I detail offer us a more nuanced view of the problems that plague Spinoza's philosophy, and they also challenge the idea that Spinoza seamlessly fits into a progressive narrative about the scientific revolution.

There is much to admire in this book. It is written in a pleasingly straightforward style, and offers insight on a wide range of important issues.

E. J. Lowe and others argue that there can be 'uncountable' things admitting of no numerical description. This implies that there can be something without there being at least one such thing, and that things can be identical without being one or nonidentical without being two. The clearest putative example of uncountable things is portions of homogeneous stuff or 'gunk'. The paper argues that there is a number of portions of gunk if there is any gunk at all, and that (...) the possibility of uncountable things is inadequately supported. (shrink)

It seems that we can know moral truths. We are also rather reluctant to defer to moral testimony. But it’s not obvious how moral cognitivism is compatible with pessimism about moral testimony. If moral truths are knowable, shouldn’t it be possible for others to know moral truths you don’t know, so that it is wise for you to defer to what they say? Or, alternatively, if it’s always reasonable to refuse to defer to the wisest among us, doesn’t this show (...) that morality is not genuinely cognitive? There is a tension in our commonsense moral epistemology. In this chapter I (a) explicate this tension, (b) criticize how others have attempted to resolve it, and finally (c) explain how Rossian deontology helps us see that the tension is only apparent: morality is indeed knowable, despite the fact that it is usually wise to refuse to defer to moral testimony.

Un examen de la division quasi officielle du monde philosophique en deux blocs : phénoménologique et analytique. Bilan de ses prolongements en France ces vingt dernières années.

Cartesian or substance dualism is the view that concrete substances come in two basic kinds. There are material things, such as biological organisms. These may be either simple or composed of parts. And there are immaterial things--minds or souls--which are always simple. No material thing depends for its existence on any soul, or vice versa. And only souls can think.

What is a temporal part? Most accounts explain it in terms of timeless parthood: a thing's having a part without temporal qualification. Some find this hard to understand, and thus find the view that persisting things have temporal parts--fourdimensionalism--unintelligible. T. Sider offers to help by defining temporal parthood in terms of a thing's having a part at a time. I argue that no such account can capture the notion of a temporal part that figures in orthodox four-dimensionalism: temporal parts must (...) be timeless parts. This enables us to state four-dimensionalism more clearly. (shrink)

Recent work in the cognitive sciences has argued that beliefs sometimes acquire signaling functions in virtue of their ability to reveal information that manipulates “mindreaders.” This paper sketches some of the evolutionary and design considerations that could take agents from solipsistic goal pursuit to beliefs that serve as social signals. Such beliefs will be governed by norms besides just the traditional norms of epistemology. As agents become better at detecting the agency of others, either through evolutionary history or individual learning, (...) the candidate pool for signaling expands. This logic holds for natural and artificial agents that find themselves in recurring social situations that reward the sharing of one’s thoughts. (shrink)

The computer revolution has had an enormous effect on all aspects of the practice of medicine, yet little thought has been given to the role of social media in identifying treatment choices for incompetent patients. We are currently living in the ?Internet age? and many people have integrated social media into all aspects of their lives. As use becomes more prevalent, and as users age, social media are more likely to be viewed as a source of information regarding medical care (...) preferences. This article explores the ethical and legal issues raised by the use of social media in surrogate decision making. (shrink)

This English translation of _Sorel’s Study on Vico_ opens the way to a radical re-evaluation not only of Sorel’s trajectory, but of his French intellectual contexts, and the anarcho-syndicalism he is sometimes said to represent.

Is wisdom a virtue? I think it is and also that it is an important virtue. But, it should be granted at the outset that the claim is controversial, that there are philosophers who either do not think of wisdom as a virtue1, or do not think of it as relevantly similar to other virtues. For example, Stanley Godlovitch comments: Wisdom sits alone. We cannot rehearse or practice it. We cannot be prompted to assume it—wheth er for our sake or (...) for the sake of others. We cannot expect, should we be in possession of it, to win friends and influence people. Wisdom calls into prominence a state of mind rather than a readiness to act in specified ways. As such, its status as a virtue must remain rather aloof.2. (shrink)

I argue that it is rational and appropriate for atheists to give thanks to deep impersonal agents for the benefits they give to us. These agents include our evolving biosphere, the sun, and our finely-tuned universe. Atheists can give thanks to evolution by sacrificially burning works of art. They can give thanks to the sun by performing rituals in solar calendars. They can give thanks to our finely-tuned universe, and to existence itself, by doing science and philosophy. But these linguistic (...) types of thanks-giving are forms of non-theistic contemplative prayer. Since these behaviors resemble ancient pagan behaviors, it is fair to call them pagan. Atheistic paganism may be part of an emerging ecosystem of naturalistic religions. (shrink)
