One of the many problems that would have t o be solved by a satisfactory theory of empirical knowledge, perhaps the most central is a general structural problem which I shall call the epistemic regress problem: the problem of how to avoid an in- finite and presumably vicious regress of justification in ones account of the justifica- tion of empirical beliefs. Foundationalist theories of empirical knowledge, as we shall see further below, attempt t o avoid the regress by locating a (...) class of empirical beliefs whose justification does not depend on that of other empirical beliefs. Extemalist theories, the topic of the present paper, represent one species of foundationalism. (shrink)

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

9/11 was an inside job. The Holocaust is a myth promoted to serve Jewish interests. The shootings at Sandy Hook Elementary School were a false flag operation. Climate change is a hoax perpetrated by the Chinese government. These are all conspiracy theories. A glance online or at bestseller lists reveals how popular some of them are. Even if there is plenty of evidence to disprove them, people persist in propagating them. Why? Philosopher Quassim Cassam explains how conspiracy theories are different (...) from ordinary theories about conspiracies. He argues that conspiracy theories are forms of propaganda and their function is to promote a political agenda. Although conspiracy theories are sometimes defended on the grounds that they uncover evidence of bad behaviour by political leaders, they do much more harm than good, with some resulting in the deaths of large numbers of people. There can be no clearer indication that something has gone wrong with our intellectual and political culture than the fact that conspiracy theories have become mainstream. When they are dangerous, we cannot afford to ignore them. At the same time, refuting them by rational argument is difficult because conspiracy theorists discount or reject evidence that disproves their theories. As conspiracy theories are so often smokescreens for political ends, we need to come up with political as well as intellectual responses if we are to have any hope of defeating them. (shrink)

Things and Their Place in Theories Our talk of external things, our very notion of things, is just a conceptual apparatus that helps us to foresee and ...

Perception is riddled with cases of reliable misperception. These are cases in which a perceptual state is tokened inaccurately any time it is tokened under normal conditions. On the face of it, this fact causes trouble for theories that provide an analysis of perceptual content in non-semantic, non-intentional, and non-phenomenal terms, such as those found in Millikan (1984), Fodor (1990), Neander (2017), and Schellenberg (2018). I show how such theories can be extended so that they cover such cases without giving (...) up their core commitments. (shrink)

The Twentieth Century has seen a dramatic rise in the use of probability and statistics in almost all fields of research. This has stimulated many new philosophical ideas on probability. _Philosophical Theories of Probability_ is the first book to present a clear, comprehensive and systematic account of these various theories and to explain how they relate to one another. Gillies also offers a distinctive version of the propensity theory of probability, and the intersubjective interpretation, which develops the subjective theory.

I critically examine some deflationary theories of properties, according to which properties are ‘shadows of predicates’ and quantification over them serves a mere quasi-logical function. I start by considering Hofweber’s internalist theory, and pose a problem for his account of inexpressible properties. I then introduce a theory of properties that closely resembles Horwich’s minimalist theory of truth. This theory overcomes the problem of inexpressible properties, but its formulation presupposes the existence of various kinds of abstract objects. I discuss some ways (...) to reduce these existence assumptions, but ultimately suggest that deflationists can hardly avoid quantification over abstract objects of one sort or another. I conclude that property deflationism is perhaps not as deflationary as some philosophers want it to be, but that it’s still apt to call the position ‘deflationary’. (shrink)

Our topic is the theory of topics. My goal is to clarify and evaluate three competing traditions: what I call the way-based approach, the atom-based approach, and the subject-predicate approach. I develop criteria for adequacy using robust linguistic intuitions that feature prominently in the literature. Then I evaluate the extent to which various existing theories satisfy these constraints. I conclude that recent theories due to Parry, Perry, Lewis, and Yablo do not meet the constraints in total. I then introduce the (...) issue-based theory—a novel and natural entry in the atom-based tradition that meets our constraints. In a coda, I categorize a recent theory from Fine as atom-based, and contrast it to the issue-based theory, concluding that they are evenly matched, relative to our main criteria of adequacy. I offer tentative reasons to nevertheless favour the issue-based theory. (shrink)

This text provides an introduction to the history and current state of theories of word meanings.

The aim of this paper is to show that it’s not a good idea to have a theory of truth that is consistent but ω-inconsistent. In order to bring out this point, it is useful to consider a particular case: Yablo’s Paradox. In theories of truth without standard models, the introduction of the truth-predicate to a first order theory does not maintain the standard ontology. Firstly, I exhibit some conceptual problems that follow from so introducing it. Secondly, I show that (...) in second order theories with standard semantics the same procedure yields a theory that doesn’t have models. So, while having an ω- inconsistent theory is a bad thing, having an unsatisfiable theory of truth is actually worse. This casts doubts on whether the predicate in question is, after all, a truthpredicate for that language. Finally, I present some alternatives to prove an inconsistency adding plausible principles to certain theories of truth. (shrink)

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.

This paper seeks to carve out a distinctive category of conspiracy theorist, and to explore the process of becoming a conspiracy theorist of this sort. Those on whom I focus claim their beliefs trace back to simply trusting their senses and experiences in a commonsensical way, citing what they take to be authoritative firsthand evidence or observations. Certain flat Earthers, anti-vaxxers, and UFO conspiracy theorists, for example, describe their beliefs and evidence this way. I first distinguish these conspiracy theorists by (...) contrasting them with another group that has recently received a lot of attention from the media, philosophers, and academics more broadly. I then dig more deeply into the nature of these conspiracy theorists’ epistemic self-understanding, in order to give an account of the process by which one becomes such a conspiracy theorist. I conclude with some takeaways and implications: first, I explore the implications of my account for whether these conspiracy theorists’ beliefs are rational; then, I argue that my account has practical takeaways about counteracting beliefs in misinformation, since strategies appropriate to this kind of conspiracy theorist may not be the same ones that are appropriate for other kinds.

The final work of the esteemed philosopher William Demopoulos supplants logical empiricism's accounts of physical theories, which fail to satisfactorily engage modern physics. Arguing for a new appreciation of the tightly woven character of theory and evidence, Demopoulos offers novel insights into the distinctive nature of quantum reality.

In this paper we compare two theories about the cognitive architecture underlying morality. One theory, proposed by Sripada and Stich (forthcoming), posits an interlocking set of innate mechanisms that internalize moral norms from the surrounding community and generate intrinsic motivation to comply with these norms and to punish violators. The other theory, which we call the M/C model was suggested by the widely discussed and influential work of Elliott Turiel, Larry Nucci and others on the “moral/conventional task”. This theory posits (...) two distinct mental domains, the moral and the conventional, each of which gives rise to a characteristic suite of judgments about rules in that domain and about transgressions of those rules. We give an overview of both theories and of the data each was designed to explain. We go on to consider a growing body of evidence that suggests the M/C model is mistaken. That same evidence, however, is consistent with the Sripada and Stich theory. Thus, we conclude that the M/C model does not pose a serious challenge for the Sripada and Stich theory. (shrink)

Climate change has become one of the most pressing problems that can threaten the existence and development of humans around the globe. Almost all climate scientists have agreed that climate change is happening and is caused mainly by greenhouse gas emissions induced by anthropogenic activities. However, some groups still deny this fact or do not believe that climate change results from human activities. This essay discusses the causes, significance, and skeptical arguments of climate change denialism, as well as the roles (...) of scientists and science communication in addressing the issues. Through this essay, we call for the active participation of scientists in science communication activities with the public, the opening of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

If the laws of nature are fine-tuned for life, can we infer other universes with different laws? How could we even test such a theory without empirical access to those distant places? Can we believe in the multiverse of the Everett interpretation of quantum theory or in the reality of other possible worlds, as advocated by philosopher David Lewis? At the intersection of physics and philosophy of science, this book outlines the philosophical challenge to theoretical physics in a measured, well-grounded (...) manner. The origin of multiverse theories are explored within the context of the fine-tuning problem and a systematic comparison between the various different multiverse models are included. Cosmologists, high energy physicists, and philosophers including graduate students and researchers will find a systematic exploration of such questions in this important book. (shrink)

Theories of Truth provides a clear, critical introduction to one of the most difficult areas of philosophy. It surveys all of the major philosophical theories of truth, presenting the crux of the issues involved at a level accessible to nonexperts yet in a manner sufficiently detailed and original to be of value to professional scholars. Kirkham's systematic treatment and meticulous explanations of terminology ensure that readers will come away from this book with a comprehensive general understanding of one of philosophy's (...) thorniest set of topics. -/- Included are discussions of the correspondence, coherence, pragmatic, semantic, performative, redundancy, appraisal, and truth-as-justification theories. There are also chapters or sections of chapters on the liar paradox, three-valued logic, Field's critique of Tarski, Davidson's program, Dummett's theory of linguistic competence, satisfaction, recursion, the extension/intension distinction, and an explanation of how theories of justification, properly understood, differ from theories of truth. -/- A persistent theme is that philosophers have too often failed to recognize that not all theories of truth are intended to answer the same question. When the various questions are made distinct, it is apparent that many of the "debates" in this field are really cases of philosophers talking past one another. There is much less disagreement within the field than has commonly been thought. (shrink)

Over three previous editions, Ten Theories of Human Nature has been a remarkably popular introduction to some of the most influential developments in Western and Eastern thought. This thoroughly revised fourth edition features substantial new chapters on Aristotle and on evolutionary theories of human nature; the latter centers on Edward O. Wilson but also outlines the ideas of Emile Durkheim, B. F. Skinner, Nikolaas Tinbergen, Konrad Lorenz, Noam Chomsky, and recent evolutionary psychology. This edition also includes a rewritten introduction that (...) invites readers (even if inclined toward fundamentalism, or to cultural relativism) to careful, critical thought about human nature; a useful new section that summarizes the history of ideas from the Stoics to the Enlightenment; and a new conclusion that suggests a way to synthesize the various theories. Lucid and accessible, Ten Theories of Human Nature, 4/e, compresses into a small space the essence of such ancient traditions as Confucianism, Hinduism, and the Old and New Testaments as well as the theories of Plato, Immanuel Kant, Karl Marx, Sigmund Freud, and Jean-Paul Sartre. The authors juxtapose the ideas of these and other thinkers and traditions in a way that helps readers understand how humanity has struggled to comprehend its nature. To encourage readers to think critically for themselves and to underscore the similarities and differences between the many theories, the book examines each one on four points--the nature of the universe, the nature of humanity, the diagnosis of the ills of humanity, and the proposed cure for these problems. Ideal for introductory courses in human nature, philosophy, religious studies, and intellectual history, Ten Theories of Human Nature, 4/e, will engage and motivate students and other readers to consider how we can understand and improve both ourselves and human society.

The paper discusses the question whether T-theories explain how it is possible to understand new sentences, or learn an infinite language, as Davidson claimed. I argue against some commentators that for explanatory power we need not require that T-theories are implicitly known or mirror cognitive structures. I note contra Davidson that the recursive nature of T-theories is not sufficient for explanatory power, since humans can work out only what is computationally tractable, and recursiveness by itself allows for intractable computational complexity. (...) I finally consider the complexity of T-theories, transformed into term rewriting systems, and find that the complexity of such systems is indeed tractable. Therefore Davidson's claim stands, even though a further condition had to be met. (shrink)

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

Abstract In the contemporary literature on self-knowledge discussion is framed by and large by two competing models of self-knowledge: the observational (or perceptual) model and the constitutive model. On the observational model self-knowledge is the result of ?cognitively viewing? one's mental states. Constitutive theories of self-knowledge, on the other hand, hold that self-knowledge is constitutive of intentional states. That is, self-ascription is a necessary condition for being in a particular mental state. Akeel Bilgrami is a defender of the constitutive model. (...) I argue that the constitutive model gives rise to a regress problem. This paper will focus on that problem as well as its application to Bilgrami's version of the constitutive model. (shrink)

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main contenders, critically (...) compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

This chapter examines the convention concerning the theories of generation and form in the field of natural philosophy in Great Britain during the seventeenth century. It explains that natural philosophers treated the questions of biological generation interchangeably with those coming from chemistry, mineralogy, and meteorology, and considers Antoine Goudin's argument that there are both efficient and final causes at work in the earth's production of rocks that resemble animals or parts of animals. The chapter also suggests that the ‘chymists’ were (...) consistently presented as a challenging third party, alongside Aristotelianism and traditional atomism, in the effort to account for the composition of natural bodies.

At the centre of the traditional discussion of truth is the question of how truth is defined. Recent research, especially with the development of deflationist accounts of truth, has tended to take truth as an undefined primitive notion governed by axioms, while the liar paradox and cognate paradoxes pose problems for certain seemingly natural axioms for truth. In this book, Volker Halbach examines the most important axiomatizations of truth, explores their properties and shows how the logical results impinge on the (...) philosophical topics related to truth. In particular, he shows that the discussion on topics such as deflationism about truth depends on the solution of the paradoxes. His book is an invaluable survey of the logical background to the philosophical discussion of truth, and will be indispensable reading for any graduate or professional philosopher in theories of truth.

Intelligence allows people to understand events and to shape their surrounding environment. This book delves deeper into the theories and applications of intelligence, showing it is a multifaceted concept —defined and explained differently by prestigious experts of various disciplines in their own research. The book provides interdisciplinary connections of intelligence as it relates to a variety of clearly outlined subject areas, and should lead to a deep understanding of the phenomenon as it pertains to practical applications in different domains. Contributors (...) in this volume present results from evolutionary biology, mathematics, artificial intelligence, medicine, psychology, cultural studies, economy, political sciences and philosophy. Individual scientific models are integrated in an interdisciplinary concept of wisdom. This volume will help enhance the common understanding of intelligence for fellow researchers and scientists alike. (shrink)

To understand Self-Representationalism you need to understand its family. Self-Representationalism is a branch of the Meta-Representationalist family, and according to theories in this family what distinguishes conscious mental representations from unconscious mental representations is that conscious ones are themselves the target of a mental meta¬-representational state. A mental state M1 is thus phenomenally conscious in virtue of being suitably represented by some mental state M2. What distinguishes the Self-Representationalist branch of the family is the claim that M1 and M2 must (...) be the same token mental state, so a mental state is phenomenally conscious in virtue of suitably representing itself. This Self-Representationalist branch of the family divides into further branches, giving us specific implementations of the Self-Representationalist approach. But before asking whether we should adopt Self-Representationalism, and in what form, we should reflect on why Meta-Representationalism is an attractive family in the first place. After all, Self-Representationalist theories trade on their family name, claiming to deliver on the promises that drive the Meta-Representationalist approach. The two most important promises of Meta-Representationalism are: a) the promise of capturing the transitivity of consciousness and; b) the promise of rendering consciousness naturalisable. I discuss each in turn. (shrink)

The book is a comparative analysis of all the major social science/political science grand theories. It focuses on developmentalism, dependency theory, the world systems approach, Marxism, institutionalism, rational choice, psychoanalysis, political sociology, sociobiology, environmentalism, neuro-politics, transitions to democracy, and non-Western systems of analysis. To facilitate comparison and analysis, a common framework and outline are employed throughout. An integrating introduction and conclusion help tie the book together.

Conspiracy theories are frequently described as a threat to democracy and conspiracy theorists portrayed as epistemically or morally unreasonable. If these characterizations are correct, then it may be the case that reasons stemming from conspiracy theorizing threaten the legitimizing function of democratic deliberation. In this paper, I will argue the opposite. Despite the extraordinary epistemic and morally unreasonable claims made by some conspiracy theorists, belief in conspiracy theories is guided by internal epistemic norms inherent in believing. By utilizing the insights (...) of the Peircean epistemic defense formulated by Cheryl Misak and Robert Talisse, I take it that these epistemic norms implicitly commit the theorist to an open democratic society.

Republican theorists have paid little attention to the normative problems of secession conflicts. So far, there is no such thing as a democratic republican theory of right of secession ; nor any comprehensive analysis of current TRS has ever been undertaken from a democratic republican point of view. This article tries to fill this second gap as a first step in order to fill that first one. In doing so, it shows how secession conflicts pose threats for two core democratic (...) republican values: freedom and inclusion. The threats are, concretely, those of exclusion, blackmailing minorities, arbitrary permanent majorities, and instability. The article also shows how, due to their respective pro-unionist or pro-secessionist biases, no current TRS seems to be able to handle those threats; and briefly outlines how a democratic republican TRS, based on a non-unilateralist logic, could be developed.

Virtue-based approaches have attracted significant recent interest in argumentation, including a recent anthology of Chinese translations of important articles in the field. In this article, adapted from the introduction to that anthology, we discuss the origins of virtue argumentation and some of the challenges it has faced, as well as attempt to provide an overview of recent work on the virtues and vices relevant to argumentation. In the final section we discuss the articles that were selected and motivate their selection.

Propositions are items that play certain theoretical roles: (among other things) they serve as objects of belief, fundamental bearers of truth-value, and the semantic contents of sentences. In this paper, I examine the key role Ockham played in the development of later medieval debates about propositions. Unlike contemporary philosophers, who typically assume that propositions are abstract entities of some sort, Ockham holds a nominalist view of propositions according to which token entities—namely, token mental representations—play the proposition role. While Ockham's view (...) generates a great deal of controversy and discussion I argue that it isn't his nominalism about propositions per se that proves objectionable. Indeed, insofar as few medieval philosophers countenance abstract objects, the view that token mental representations function as fundamental bearers of truth and as the semantic content of sentences is fairly standard. What does prove controversial, I claim, is Ockham's contention that token mental states—what he refers to as ‘mental sentences’—serve as objects for propositional attitudes. My discussion in the paper explores both (i) the reasons why Ockham’s attempt to treat mental representations as objects for belief and knowledge proved controversial and (ii) what alternative positions emerged in the subsequent debate about propositional attitudes. -/- .

Quassim Cassam has argued that psychological and epistemological analyses of conspiracy theories threaten to overlook the political nature of such theories. According to Cassam, conspiracy theories are a form of political propaganda. I develop a limited critique of Cassam's analysis.This paper advances two core theses. First, acceptance of conspiracy theories requires a rejection of epistemic authority that renders conspiracy theorists susceptible to co-option by certain political programs while insulating such programs from criticism. I argue that the contrarian nature of conspiracy (...) theories partially accounts for the prominence of such theories in populist movements.Second, the contrarian nature of conspiracy theories partially accounts for their attractiveness, especially among those to whom populism already appeals. I argue that for those who resent what appears from their perspective as the shaping of the epistemic landscape by alien perspectives, conspiracy theorizing may facilitate the reassertion of epistemic autonomy.
