How induction was understood took a substantial turn during the Renaissance. At the beginning, induction was understood as it had been throughout the medieval period, as a kind of propositional inference that is stronger the more it approximates deduction. During the Renaissance, an older understanding, one prevalent in antiquity, was rediscovered and adopted. By this understanding, induction identifies defining characteristics using a process of comparing and contrasting. Important participants in the change were Jean Buridan, humanists such as Lorenzo Valla and (...) Rudolph Agricola, Paduan Aristotelians such as Agostino Nifo, Jacopo Zabarella, and members of the medical faculty, writers on philosophy of mind such as the Englishman John Case, writers of reasoning handbooks, and Francis Bacon.

John Norton says that philosophers have been led astray for thousands of years by their attempt to treat induction formally. He is correct that such an attempt has caused no end of trouble, but he is wrong about the history. There is a rich tradition of non-formal induction. In fact, material theories of induction prevailed all through antiquity and from the Renaissance to the mid-1800s. Recovering these past systems would not only fill lacunae in Norton’s own theory but would (...) highlight areas where Norton has not freed himself from the straightjacket of formal induction as much as he might think. This essay begins that recovery. (shrink)

Aristotle said that induction (epagōgē) is a proceeding from particulars to a universal, and the definition has been conventional ever since. But there is an ambiguity here. Induction in the Scholastic and the (so-called) Humean tradition has presumed that Aristotle meant going from particular statements to universal statements. But the alternate view, namely that Aristotle meant going from particular things to universal ideas, prevailed all through antiquity and then again from the time of Francis Bacon until the mid-nineteenth century. Recent (...) scholarship is so steeped in the first-mentioned tradition that we have virtually forgotten the other. In this essay McCaskey seeks to recover that alternate tradition, a tradition whose leading theoreticians were William Whewell, Francis Bacon, Socrates, and in fact Aristotle himself. The examination is both historical and philosophical. The first part of the essay fills out the history. The latter part examines the most mature of the philosophies in the Socratic tradition, specifically Bacon’s and Whewell’s. After tracing out this tradition, McCaskey shows how this alternate view of induction is indeed employed in science, as exemplified by several instances taken from actual scientific practice. In this manner, McCaskey proposes to us that the Humean problem of induction is merely an artifact of a bad conception of induction and that a return to the Socratic conception might be warranted.

A revisionist account of how philosophical induction was conceived in the ancient world and how that conception was transmitted, altered, and then rediscovered. I show how philosophers of late antiquity and then the medieval period came step-by-step to seriously misunderstand Aristotle’s view of induction and how that mistake was reversed by humanists in the Renaissance and then especially by Francis Bacon. I show, naturally enough then, that in early modern science, Baconians were Aristotelians and Aristotelians were Baconians.

Since at least late antiquity, Aristotle’s Prior Analytics B 23 has been misread. Aristotle does not think that an induction is a syllogism made good by complete enumeration. The confusion can be eliminated by considering the nature of the surviving text and watching very closely Aristotle’s moving back and forth between “induction” and “syllogism from induction.” Though he does move freely between them, the two are not synonyms.

The philosophical background important to Mill’s theory of induction has two major components: Richard Whately’s introduction of the uniformity principle into inductive inference and the loss of the idea of formal cause.

The 19th-century philosopher John Stuart Mill is widely regarded as one of history’s leading proponents of inductive science and of political liberty. Yet, oddly, philosophers working in his train have been remarkably unsuccessful in saying exactly what is wrong with the scientific skepticism or the political tyrannies of the past one hundred and fifty years. Is it possible that Mr. Mill was not such a good guy after all? … I recommend the book to anyone interested in a scholarly (...) treatment of Victorian England, of 19th-century science, of the history of scientific method, of the philosophy of induction, or of the underappreciated historian and philosopher William Whewell. For anyone who thinks John Stuart Mill was a champion of commonsense realism, inductive science, or individual liberty, the book is a must-read. (shrink)

In this well-structured monograph, Stephen A. McKnight seeks to correct the view that Francis Bacon’s use of religious motifs and tropes is “manipulative,” “cynical,” and “disingenuous,” a view McKnight considers the “prevailing” one. To accomplish his goal, McKnight subjects several of Bacon’s works to a close reading. He concludes that the “pervasiveness of religious motifs, scriptural references, and biblical doctrines” in Bacon’s writings “establish the central role religion plays in Bacon’s thought”. McKnight holds that Bacon’s religiosity is not disingenuous, but (...) sincere. . . . . In documenting religious motifs in several of Bacon’s writings, this book is a valuable success. In characterizing Bacon’s religious beliefs and how they influenced the rest of his thought, it is much less convincing. (shrink)

This work intentionally joins Stephen A. McKnight’s The Religious Foundations of Francis Bacon’s Thought in arguing that Sir Francis Bacon was more deeply religious than he is conventionally thought to have been. Though the book is full of interesting suggestions, a lack of breadth, rigor, and precision will leave many readers unconvinced. . . . Those who know the corpus and secondary literature enough to read critically will find here provocative suggestions and intriguing leads. Others will need to be cautious (...) about the book’s arguments and conclusions. (shrink)

Sgarbi just shows that in the century before Locke’s Essay Concerning Human Understanding many writers mentioned induction and many claimed that knowledge must rely somehow on sense experience. An attempt to revive Randall’s thesis needs more than that.

Groarke is surely right that Aristotle believed the cognitive hierarchy he described in Posterior Analytics B 19 is central to, and not antithetical to, validating the syllogism described in Prior Analytics B 23. But did Aristotle really believe induction ultimately relies on what Groarke calls “a stroke or leap of understanding,” “immediate illumination,” “moment of immediate cognition,” “a direct insight,” “moment of illumination,” and so on? . . . Overall, what Groarke says here is provocative and inviting, even if not (...) definitive. (shrink)

The issue of the relation of the sacred to the secular has become paramount in virtually every country in the world. From church-state relations in the US, with the debates around abortion and same-sex marriage, to the vitriolic discussions in France over the veil (hijab) sacred-secular, faith-reason, transcendence-imminence -- impacts every aspect of personal, social, and political life. Indeed, the questions often asked are whether Huntington s, Clash of Civilizations is today s reality? Is clash and conflict inevitable? This volume (...) collects papers from scholars from all around the globe and digs into that question. Do the sacred and the secular necessarily end in conflict? Building on scholars such as Charles Taylor, Hans-Georg Gadamer, Jurgen Habermaus, and John Rawls, as well as the world s great religious traditions, the authors assembled here respond with a nuanced, but resounding, NO. A deeper read demands the possibility, indeed, necessity, of complementarity. It has become ever more urgent to discover the proper and complementary relation between the two so that both can be promoted through mutual collaboration. The deeper implications of the discussion can be perceived in many current global problems: cultural identity, multiculturalism, pluralism, nationalism, economic inequality, race, terrorism, migration, public education, and climate change. The volume unfolds in seven sections: Foundations; Sacred and Secular; Complement or Conflict; Hermeneutics; African traditions; South Asian Traditions; Chinese Traditions; and Islamic Traditions. It is fascinating to observe how the various authors grapple with unfolding the relation of sacred/secular, faith/reason, church-mosque/state, transcendence/imminence. The section on Islam illustrates this. These chapters deal with the thorny, usually misunderstood debate between the scholars and those, westerners refer to as fundamentalists or radicals. In the latter, there is no space left to reason, interpretation, or historical criticism. This ugly divide usually emerges in the hot-button issues like the treatment of women and religion-related terrorism. However, these oversimplifications betray the intellectual roots of Islamic tradition. Here the argument is advanced that there are common and multiple meanings of rationality in the Islamic primary sources and that doctrine, the Qur an, and the Sunnah, open considerable space for the rational and the secular in Islamic teachings. Unknown to most in the West, the grappling within Islam goes on. Moreover, the grappling seems to be heating up in all traditions. We are all called to the discussion. Our globe needs it! (shrink)

In this paper Sullins argues that in certain circumstances robots can be seen as real moral agents. A distinction is made between persons and moral agents such that, it is not necessary for a robot to have personhood in order to be a moral agent. I detail three requirements for a robot to be seen as a moral agent. The first is achieved when the robot is significantly autonomous from any programmers or operators of the machine. The second is when (...) one can analyze or explain the robot's behavior only by ascribing to it some predisposition or 'intention' to do good or harm. And finally, robot moral agency requires the robot to behave in a way that shows and understanding of responsibility to some other moral agent. Robots with all of these criteria will have moral rights as well as responsibilities regardless of their status as persons. (shrink)

A philosopher once wrote the following words:If I examine the PTOLOMAIC and COPERNICAN systems, I endeavour only, by my enquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relations, that they bear towards each other in the heavens.

In this article I contrast 17th and 18th explanations of hysteria including those of Sydenham and Willis with those given by Plato and pre-modern medicine. I show that beginning in the second decade of the 17th century the locus of the disorder was transferred to the nervous system and it was no longer connected with the womb as in Hippocrates and Galen; hysteria became identified with hypochondria, and was a disease contracted by men as well as women. I discuss the (...) purely mechanical explanation of hysteria given by Robert Boyle who attributed its cause to corporeal ideas as well as overly sensitive disposition of the nervous system. I relate this the mechanical theory of the nervous system prominent in Descartes' writings on physiology. The paper closes with a discussion of the contrast between early modern explanations of hysteria and the nature of man with those of Freud in the early 20th century. (shrink)

Social media platforms have been rapidly increasing the number of informational labels they are appending to user-generated content in order to indicate the disputed nature of messages or to provide context. The rise of this practice constitutes an important new chapter in social media governance, as companies are often choosing this new “middle way” between a laissez-faire approach and more drastic remedies such as removing or downranking content. Yet information labeling as a practice has, thus far, been mostly tactical, reactive, (...) and without strategic underpinnings. In this paper, we argue against defining success as merely the curbing of misinformation spread. The key to thinking about labeling strategically is to consider it from an epistemic perspective and to take as a starting point the “social” dimension of online social networks. The strategy we articulate emphasizes how the moderation system needs to improve the epistemic position and relationships of platform users — i.e., their ability to make good judgements about the sources and quality of the information with which they interact on the platform — while also appropriately respecting sources, seekers, and subjects of information. A systematic and normatively grounded approach can improve content moderation efforts by providing clearer accounts of what the goals are, how success should be defined and measured, and where ethical considerations should be taken into consideration. We consider implications for the policies of social media companies, propose new potential metrics for success, and review research and innovation agendas in this regard. (shrink)

The linguistic foundations of science and technology include many terms that have been borrowed from ancient languages. In the case of terms with origins in the Greek language, the modern meaning can often differ significantly from the original one. Here we use the PubMed database to demonstrate the prevalence of words of Greek origin in the language of modern science, and call for scientists to exercise care when coining new terms.

We propose a multi-step evaluation schema designed to help procurement agencies and others to examine the ethical dimensions of autonomous systems to be applied in the security sector, including autonomous weapons systems.

A dilemma exists when a doctor is faced with a child or young person who refuses medically indicated treatment. The Gillick case has been interpreted by many to mean that a child of sufficient age and intelligence could validly consent or refuse consent to treatment. Recent decisions of the Court of Appeal on a child's refusal of medical treatment have clouded the issue and undermined the spirit of the Gillick decision and the Children Act 1989. It is now the case (...) that a child patient whose competence is in doubt will be found rational if he or she accepts the proposal to treat but may be found incompetent if he or she disagrees. Practitioners are alerted to the anomalies now exhibited by the law on the issue of children's consent and refusal. The impact of the decisions from the perspectives of medicine, ethics, and the law are examined. Practitioners should review each case of child care carefully and in cases of doubt seek legal advice.

Nuestro interés en el contenido mental no-conceptual es, principalmente, la articulación de una versión sustantiva (no-trivial) de esta clase de contenido en la experiencia perceptual. El debate acerca del contenido no-conceptual ha girado, en su mayor parte, alrededor de su existencia; y los argumentos que se han ofrecido en su favor abogan por una versión no sustantiva según la cual el contenido no-conceptual es aquel que no satisface ciertos requisitos conceptuales. Así, para desarrollar una versión sustantiva del contenido mental no-conceptual (...) hemos apelado a la versión de la experiencia perceptual de propiedades espaciales ofrecida por Evans (1982 cap. 6). A partir de esto desarrollamos un nuevo argumento a favor del contenido no-conceptual de la experiencia perceptual que lo vincula a la actividad característica de la experiencia perceptual. Por último, exponemos uno de los ataques de McDowell (1996) a la noción de contenido no-conceptual y presentamos nuestras réplicas a este ataque, mostrando su insuficiencia. Al mostrar que la crítica de McDowell no es exitosa, consideramos que podríamos tener una versión del contenido no-conceptual de la experiencia que es inmune a esta línea de argumentación. (shrink)

Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

A single mother is a person who is accountable for raising their children alone because they do not have a husband or live-in partner. Single mothers claim to have no co-parenting relationships at all, comparing single parents to those who are married, cohabiting, or without children, single parents experience the worst work-life balance. A single parent may feel overwhelmed by the demands of juggling child care, a career, paying bills, and maintaining household responsibilities. Single-parent households frequently deal with several extra (...) obligations and possible complications that other families would not. The study also emphasizes the difficulties and coping mechanisms faced by contractual single parents as well as their lived experiences. The study's findings, which were based on an Interpretative Phenomenological Analysis, were as follows: (1) Work-life balance can be difficult for single parents. They struggle to keep their jobs while taking care of their family because they are the only ones in charge of the children. (2) Single contractual mothers face particular difficulties due to a lack of resources for basic expenses. (3) Contractual single women lean on their kids, the good people in their lives, and their faith in God to get through problems. (shrink)

Education is essential to life, and the epidemic affected everything. Parents want to get their kids the most important teaching. However, since COVID-19 has affected schools and other institutions, providing education has become the most significant issue. Online learning pedagogy uses technology to provide high-quality learning environments for student-centered learning. Further, this study explores the experiences and challenges faced by Filipino tertiary students regarding the lack of gadgets amidst online learning. Employing the Interpretative Phenomenological Analysis, the findings of this study (...) were: Some college students still have difficulty with online learning. Attending online classes is difficult, especially for students with limited resources. Smartphones, other gadgets, and internet connections play a significant role in online classrooms because they are the ones that students utilize while learning online, which is essential for successful participation in online higher education as well as for solving a variety of other difficulties in the new normal. Further, College students face similar health challenges. Having an online learning setup is not just about students' struggles with learning resources but also about their health issues. When our respondents used their smartphones for an extended period, they reported eye aches and blurred vision. They also said that some of their body parts, such as their legs and back, are aching, and feel pressured because they tend to overthink things in their surroundings, which causes them incredible difficulty in performing their best in attending online classes. Even though college students continue to suffer from a lack of learning resources during online sessions, they do their best to manage their needs and the scarcity of learning resources. Students have unique coping methods for dealing with difficulties in online classes. (shrink)

This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

The main aims in this article are to discuss and criticize the core thesis of a position that has become known as phenomenal conservatism. According to this thesis, its seeming to one that p provides enough justification for a belief in p to be prima facie justified. This thesis captures the special kind of epistemic import that seemings are claimed to have. To get clearer on this thesis, the article embeds it, first, in a probabilistic framework in which updating on (...) new evidence happens by Bayesian conditionalization, and second, a framework in which updating happens by Jeffrey conditionalization. The article spells out problems for both views, and then generalizes some of these to nonprobabilistic frameworks. The main theme of the discussion is that the epistemic import of a seeming should depend on its content in a plethora of ways that phenomenal conservatism is insensitive to. (shrink)

The overall goal of the approach developed in this paper is to estimate the likelihood of a given kinetic kill scenario between hostile spacebased adversaries using the mathematical framework of Complex Conceptual Spaces Single Observation. Conceptual spaces are a cognitive model that provide a method for systematically and automatically mimicking human decision making. For accurate decisions to be made, the fusion of both hard and soft data into a single decision framework is required. This presents several challenges to this data (...) fusion framework. The first is the challenge involved in handling multiple complex terminologies, which is addressed by drawing on a set of Space Domain Ontologies. Another challenge is the complex combinatorics involved when considering all possible feature combinations. This can be mitigated by using integer linear programming optimization that is outlined by the Complex Conceptual Spaces Single Observation mathematical model framework. A third challenge is the complicated physics that is involved in a spacecraft collision that must be addressed to obtain a better understanding of threat assessment. Overcoming these various challenges allows for a quantitative ranking for the potential of a kinetic kill collision across multiple spacecraft pairs. In addition to overcoming these challenges this paper will break down threat assessment into four domains and identify a ranking of threat both for each individual domain and for the four domains combined. Simulation results are shown to verify the developed concepts. (shrink)

Quarantines and virtual learning became necessary as a result of the COVID-19 pandemic. This study investigates the challenges and opportunities in virtual classes; and how they affect the academic goals. There were 150 secondary students from Junior and Senior High School levels of education in the Philippines, who were deliberately selected; and they participated in the quantitative online survey that used a 62-item self-made 4-point Likert scale questionnaire, with 0.81 reliability coefficients. The data were evaluated by means of the percentage, (...) the mean, and the standard deviation. Sex and secondary education levels were used, in order to compare the students’ challenges and opportunities. One-way ANOVA compared the male and female respondents’ perceived challenges and opportunities. The results revealed that junior high-school (JHS) girls highlighted academic satisfaction; while school-life balance, and virtual learning helped as challenges and opportunities. The females found school-life balance, communication (F(1,149)=11.098; F(1,149)=8.430, p<0.01), academic fulfilment, self-directedness, and time-management (F(1,149)=4.224; F(1,149)=4.470; F(1,149)=4.030, p<0.05) more difficult than did the males. Senior high school (SHS) students were less satisfied with the virtual teaching (F(1,149)=14.391, p<0.001), technology use (F(1,149)=7.342, p<0.01), and communication (F(1,149)=3.934, p<0.05) than JHS students. Males were more satisfied with school and teachers’ assistance (F(1,149)=7.482, p<0.01). Some viewed virtual learning more favourably; and they regard themselves as being adaptive; they think the subject matter and learning tasks are interrelated; and they viewed virtual feedback more positively (F(1,149)=6.438; F(1,149)=5.900; F(1,149)=5.183; F(1,149)=4.470, p<0.05). The JHS students reported subject matter and the virtual learning tasks as being interrelated; and they valued virtual feedback, school and teacher support, and the adaptability to change. Challenges and opportunities may serve as the foundation for establishing a more inclusive policy on virtual learning implementation, with school and stakeholders’ cooperation needed to sustain learners’ holistic development.

The accepted narrative treats John Stuart Mill’s Kinds as the historical prototype for our natural kinds, but Mill actually employs two separate notions: Kinds and natural groups. Considering these, along with the accounts of Mill’s nineteenth-century interlocutors, forces us to recognize two distinct questions. First, what marks a natural kind as worthy of inclusion in taxonomy? Second, what exists in the world that makes a category meet that criterion? Mill’s two notions offer separate answers to the two questions: natural (...) groups for taxonomy and Kinds for ontology. This distinction is ignored in many contemporary debates about natural kinds and is obscured by the standard narrative that treats our natural kinds just as a development of Mill’s Kinds. (shrink)

This paper argues for externalism about justification on the basis of thought experiments. I present cases in which two individuals are intrinsically and introspectively indistinguishable and in which intuitively, one is justified in believing that p while the other is not. I also examine an argument for internalism based on the ideas that we have privileged access to whether or not our own beliefs are justified and that only internalism is compatible with this privilege. I isolate what I take to (...) be the most plausible form of privileged access to justification and show that it is compatible with externalism. (shrink)

Almost everyone believes that testimony can transmit knowledge from speaker to hearer. What some philosophers mean by this is ordinary and pedestrian-- they mean only that, in at least some cases, a speaker S knows that p, S testifies that p to a hearer H, and H comes to know that p as a result of believing S's testimony. There is disagreement about how this occurs, but that it does occur is sufficient for the transmission of knowledge in the intended (...) sense. On this understanding of transmission, the natural questions are these: (1) What conditions, in addition to speaker knowledge and speaker testimony, are sufficient for the hearer to gain testimonial knowledge?; and (2) Is speaker knowledge always necessary for testimonial knowledge? That is: Is all testimonial knowledge transmitted knowledge? (shrink)

In general we think of reasoning as a way of moving from some body of evidence to a belief that is drawn as a conclusion from it. But is it possible for reasoning to conclude in action, i.e., in a person’s intentionally doing one thing or another? In PRACTICAL SHAPE Jonathan Dancy answers 'Yes', on the grounds that "when an agent deliberates well and then acts accordingly, the action done is of the sort most favoured by the considerations rehearsed, taken (...) as a whole—just as when an agent reasons well and then believes accordingly, the belief formed ... is of the sort most favoured by the considerations rehearsed, again taken as a whole" (Dancy 2018, p. 29). I critique this supposed parallelism between reasoning to action and reasoning to belief, arguing in two ways that in practical reasoning the action that is one’s conclusion need not be meant to be, or to be of a sort, that is most favored by the considerations that one reasons from. I then go on to explain why this should be: that in practical reasoning the correct conclusion to draw is not supposed to have been determined in advance, because this is a form of reasoning by which we create truth through acting rather than reflecting a truth that is independently so.

When we ask what natural kinds are, there are two different things we might have in mind. The first, which I’ll call the taxonomy question, is what distinguishes a category which is a natural kind from an arbitrary class. The second, which I’ll call the ontology question, is what manner of stuff there is that realizes the category. Many philosophers have systematically conflated the two questions. The confusion is exhibited both by essentialists and by philosophers who pose their accounts in (...) terms of similarity. It also leads to misreading philosophers who do make the distinction. Distinguishing the questions allows for a more subtle understanding of both natural kinds and their underlying metaphysics. (shrink)

We think we have lots of substantial knowledge about the future. But contemporary wisdom has it that indeterminism prevails in such a way that just about any proposition about the future has a non-zero objective chance of being false.2, 3 What should one do about this? One, pessimistic, reaction is scepticism about knowledge of the future. We think this should be something of a last resort, especially since this scepticism is likely to infect alleged knowledge of the present and past. (...) One anti-sceptical strategy is to pin our hopes on determinism, conceding that knowledge of the future is unavailable in an indeterministic world. This is not satisfying either: we would rather not be hostage to empirical fortune in the way that this strategy recommends. A final strategy, one that we shall explore in this paper, is one of reconciliation: knowledge of a proposition is compatible with a subject’s belief having a non-zero objective chance of error.4 Following Williamson, we are interested in tying knowledge to the presence or absence of error in close cases, and so we shall explore the connections between knowledge and objective chance within such a framework. We don’t want to get tangled up here in complications involved in attempting to formulate a necessary and sufficient condition for knowledge in terms of safety. Instead, we will assume the following rough and ready necessary condition: a subject knows P only if she could not easily have falsely believed P.5 Assuming that easiness is to be spelt.. (shrink)

The consequence argument purports to show that determinism is true only if no one has free will. Judgments about whether the argument is sound depend on how one understands locutions of the form 'p and no one can render p false'. The main interpretation on offer appeals to counterfactual sufficiency: s can render p false just in case there is something s can do such that, were s to do it, p would be false; otherwise, s cannot render p false. (...) Here I show that, in the context of the consequence argument, this interpretation conflicts with widely endorsed principles governing the logic of counterfactuals. (shrink)

According to the standard narrative, natural kind is a technical notion that was introduced by John Stuart Mill in the 1840s and the recent craze for natural kinds, launched by Putnam and Kripke, is a continuation of that tradition. I argue that the standard narrative is mistaken. The Millian tradition of kinds was not particularly influential in the 20th-century, and the Putnam-Kripke revolution did not clearly engage with even the remnants that were left of it. The presently active tradition (...) of natural kinds is less than half a century old. Recognizing this might help us better appreciate both Mill and natural kinds. (shrink)

Philosophers have often noted a contrast between practical and theoretical reasons when it comes to cases involving equally balanced reasons. When there are strong practical reasons for A-ing, and equally strong practical reasons for some incompatible option, B-ing, the agent is permitted to make an arbitrary choice between them, having sufficient reason to A and sufficient reason to B. But when there is strong evidence for P and equally strong evidence for ~ P, one isn’t permitted to simply believe one (...) or the other. Instead, one must withhold belief, neither believing that P nor believing that ~ P. This paper examines what explains this contrast, focusing in particular on a proposal recently developed by Mark Schroeder across several papers. Schroeder aims to explain the contrast by an appeal to non-evidential, epistemic reasons against belief. But, I argue, it’s not clear exactly what those reasons are, nor how those reasons are to be weighed against evidential reasons. Despite these challenges, I argue that there are grounds for optimism that the contrast can be explained within the broad framework Schroeder provides, and I aim to provide resources to meet the aforementioned challenges.

Closure is the epistemological thesis that if S knows that P and knows that P implies Q, then if S infers that Q, S knows that Q. Fred Dretske acknowledges that closure is plausible but contends that it should be rejected because it conflicts with the plausible thesis: Conclusive reasons (CR): S knows that P only if S believes P on the basis of conclusive reasons, i.e., reasons S wouldn‘t have if it weren‘t the case that P. Dretske develops an (...) analysis of knowing that centers on CR, and argues that the requirement undermines skepticism by implying the falsity of closure. We develop a Dretske-style analysis of knowing that incorporates CR, and we argue that this analysis not only accords with closure, but also implies it. In addition, we argue that the analysis accounts for the prima facie plausibility of closure-invoking skeptical arguments, and nonetheless implies that they are fallacious. If our arguments turn out to be sound, the acceptability of Dretske‘s analysis of knowing will be significantly enhanced by the fact that, despite implying closure, it undermines closure-based skepticism.

This paper explores the possibility that causal decision theory can be formulated in terms of probabilities of conditionals. It is argued that a generalized Stalnaker semantics in combination with an underlying branching time structure not only provides the basis for a plausible account of the semantics of indicative conditionals, but also that the resulting conditionals have properties that make them well-suited as a basis for formulating causal decision theory. Decision theory (at least if we omit the frills) is not an (...) esoteric science, however unfamiliar it may seem to an outsider. Rather it is a systematic exposition of the consequences of certain well-chosen platitudes about belief, desire, preference and choice. It is the very core of our common-sense theory of persons, dissected out and elegantly systematized. (David Lewis, Synthese 23:331–344, 1974, p. 337). A small distortion in the analysis of the conditional may create spurious problems with the analysis of other concepts. So if the facts about usage favor one among a number of subtly different theories, it may be important to determine which one it is.
