Was Galileo’s clash with the Church about science or about legal procedures that he had apparently neglected? Was he ultimately condemned for heresy or for violating a legal precept by publishing the "Dialogue on the Two Chief World Systems"?

Why do average Americans recall the wise words of their politicians (e.g., John F. Kennedy’s “Ask not what your country can do for you. . .”) but forget those of their political philosophers (e.g., John Rawls’s two principles of justice)? Notably absent from Sandel’s list is Benjamin Franklin, the author, printer, scientist, and statesman who led the United States through a tumultuous period of colonial politics, a revolutionary war, and its momentous, though no less precarious, founding as a nation. (...) class='Hi'>Lorraine Smith Pangle’s new book on Franklin seeks to remedy another glaring omission, namely, “that while so much attention has been paid to Franklin’s life, so little has hitherto been given to his political thought.".

I argue that interesting experiences are experientially valuable in the same fashion as pleasant experiences, yet that the interesting is nonetheless a distinct value from the pleasant. Insofar as it challenges the hedonist’s assumption that pleasure and pain are the only evaluative dimensions of our phenomenological experiences, my argument here serves both as a defense of the value of the interesting and as an important critique of hedonism.

This paper introduces the notion of a “psychologically rich life”: a life characterized by complexity, in which people experience a variety of interesting things, and feel and appreciate a variety...

In this paper I discuss five meta-ethical challenges to Naturalistic Moral Realism, which includes secular moral codes such as Secular Humanism that, in my view, naturalists need to address to keep their commitment to moral realism from looking like special pleading. The five challenges are as follows: 1. The Ontological Problem (OP): How do such moral principles exist? 2. The Epistemic Problem (EP): How does our moral sense/intuition track such principles? 3. The Influence Problem (IP): What authority does the existence (...) of such principles have to supervene on our behavior? 4. The Axiological Problem (AP): What entities have moral value and deserve moral consideration? 5. Methodological Problem (MP): How do we go about arbitrating between moral claims when they conflict?

This paper proposes the idea of thinking about practical rationality in terms of self-regulation and defends the thesis that self-regulation is a virtue, insofar as we have reason to think it is our highest form of practical rationality. I argue that understanding self-regulation as a virtuous form of practical reasoning is called for given the kinds of limitations we face in developing agency and pursuing our goals, and presents us with several advantages over traditional understandings of practical rationality.

How should our metaphysical commitments influence how we think of ourselves in the practical world? Hume and Buddhism share common ground in denying that there exists a metaphysically real self yet offer very different practical recommendations about how this metaphysical view ought to inform our practical identities. This paper explores the contrast between the two views. It examines the benefits and costs of embracing, and attaching to, a practical conception of the self in the absence of a metaphysical self and (...) provides a qualified defense of the Humean approach by way of considering the joys of attachment.

In this reply to comments by Neera Badhwar and Barbara Montero, I examine more deeply the nature of cognitive engagement and how it is distinct from other forms of cognitive activity; revisit the distinction between interesting and boring experiences; and present an analysis of all-things-considered value that illustrates the contributions that the interesting makes. I conclude by considering what all-things-considered value becomes for patients with severe cognitive impairments.

In recent papers, I defend the intrinsic value of the interesting, and the intrinsic disvalue of the boring. My arguments introduce two claims with important implications for discussions of the quality of life. The first is that when it comes to experiences, there’s more value at stake than pleasure alone. The second is that there is value to cognitive engagement itself, even when it is unstructured by desires or reasons. This paper explores the important consequences these conclusions have for how (...) we appraise the quality of life of subjects with dramatically impaired cognitive capacities (such as patients with advanced Alzheimer’s and patients in a persistent vegetive state). I examine whether such groups are capable of experiencing the interesting and, by extension, what degrees of self-awareness are required to experience the kind of cognitive engagement at stake in interesting experiences.

In this essay, I will explain why Methodological Naturalism (MN) fails as a demarcating criteria for science. I will argue that MN is not precise enough to be useful for demarcation, unable to follow the evidence where it leads, not theologically neutral (despite its stated goals as such), and difficult to justify (and currently unjustified) as an ontological or epistemic principle.

The Theistic Argument from Intentionality (TAI) is a venerable argument for the existence of God from the existence of eternal truths. The argument relies, inter alia, on the premises that (i) truth requires representation, and that (ii) non-derivative representation is a function of, and only of, minds. If propositions are the fundamental bearers of truth and falsity, then these premises entail that propositions (or at least their representational properties) depend on minds. Although it is widely thought that psychologism—the view that (...) the fundamental truth-bearers are mind-dependent—was refuted by Frege, a psychologistic view of propositions has been undergoing a revival. However, this new psychologism suffers from a problem of scarcity—finite minds cannot generate enough thoughts to play the role of fundamental truth-bearers. This objection paves the way for a revised version of the TAI: only an infinite mind can furnish enough thoughts to play the role of propositions. (shrink)

This paper investigates the emotional import of literary devices deployed in fiction. Reflecting on the often-favored approach in the analytic tradition that locates fictional characters, events, and narratives as sources of readers’ emotions, I attempt to broaden the scope of analysis by accounting for how literary devices trigger non-cognitive emotions. I argue that giving more expansive consideration to literary devices by which authors present content facilitates a better understanding of how fiction engages emotion. In doing so, I also explore the (...) somatic dimension of reading fiction. (shrink)

The limited aim here is to explain what John Dewey might say about the formulation of the grue example. Nelson Goodman’s problem of distinguishing good and bad inductive inferences is an important one, but the grue example misconstrues this complex problem for certain technical reasons, due to ambiguities that contemporary logical theory has not yet come to terms with. Goodman’s problem is a problem for the theory of induction and thus for logical theory in general. Behind the whole discussion of (...) these issues over the last several decades is a certain view of logic hammered out by Russell, Carnap, Tarski, Quine, and many others. Goodman’s nominalism hinges in essential ways on a certain view of formal logic with an extensional quantification theory at its core. This raises many issues, but the one issue most germane here is the conception of predicates ensconced in this view of logic. (shrink)

I present a possible worlds semantics for a hyperintensional belief revision operator, which reduces the logical idealization of cognitive agents affecting similar operators in doxastic and epistemic logics, as well as in standard AGM belief revision theory. (Revised) belief states are not closed under classical logical consequence; revising by inconsistent information does not perforce lead to trivialization; and revision can be subject to ‘framing effects’: logically or necessarily equivalent contents can lead to different revisions. Such results are obtained without resorting (...) to non-classical logics, or to non-normal or impossible worlds semantics. The framework combines, instead, a standard semantics for propositional S5 with a simple mereology of contents. (shrink)

Scholarly opinions vary on what language is, how it evolved, and from where or what it evolved. Long considered uniquely human, today scholars argue for evolutionary continuity between human language and animal communication systems. But while it is generally recognized that language is an evolving communication system, scholars continue to debate from which species language evolved, and what behavioral and cognitive features are the precursors to human language. To understand the nature of protolanguage, some look for homologs in gene functionality, (...) brain areas, or anatomical structures such as the supralaryngeal vocal tract; others point toward primates, their gestural, vocal, multimodal, and in later evolving hominins also their pantomimic communication systems; and still others draw parallels between the musicality that characterizes language and the pitch found in the numerous sounds produced by animals. Accordingly, protolanguage theories today are multiple and diverse, and protolanguages might have also been diverse. This special issue on Evolving (Proto)Language/s for Lingua bundles several of the protolanguage theories that were put forward at the sixth edition of the Ways to Protolanguage conference series, held at the Calouste Gulbenkian Foundation in Lisbon, in 2019. Not aimed at surveying all the different ways there are to conceptualize, study, and model protolanguage/s, this issue provides interested readers with good overviews on the role played in current theorizing on protolanguage/s by (paleo)anthropology, genetics, physiology, developmental, evolutionary, ecological, and pragmatic research lines.

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

Lawrence Kohlberg's Approach to Moral Education presents what the late Lawrence Kohlberg regarded as the definitive statement of his educational theory. Addressing the sociology and social psychology of schooling, the authors propose that school culture become the center of moral education and research. They discuss how schools can develop as just and cohesive communities by involving students in democracy, and they focus on the moral decisions teachers and students face as they democratically resolve problems. As the authors put it: "...we (...) propose an educational renewal of our democratic society.... We have attempted to establish schools that do more than just teach about democratic citizenship, that are themselves democratic societies.". (shrink)

In this article, I will discuss some of the arguments for and against the existence of God, in particular the monotheistic God believed in the Abramahamic religions (Judiasm, Islam, and Christianity) as well as Babism, the Bahai Faith, and Sikhism. Arguments for the existence of God try to argue that either God exists (based on other things people agree with) or that belief in God is reasonable. Arguments against the existence of God try to argue that the existence of God (...) leads to some contradiction or other absurdity. (shrink)

Anti-intellectualism involves general mistrust of scholars, academics, and ex- perts, often as pretentious or power-motivated. While scholars have described currents of anti-intellectualism in American public life, evangelical Christianity, in responses to COVID, and rural identity, to my knowledge none have looked at how anti-intellectualism specifically manifests in the New Atheism movement. In this work, we explore the way anti-intellectualism is commonly found and expressed in New Atheism and the modern Skeptical Movement, including scientific skepticism more generally.

Summary: A review of the cognitivist/extended cognition and extended mind landscape.

The problem of evil is one of the most significant challenges to theism and Christianity in particular, asking why there seems to be so much evil if an omnibenevolent (all good), loving God exists. The problem of evil, as posed by many atheists and agnostics today, (following Epicurus) often asserts that the following premises cannot all be true: 1. God exists, and is omnipotent (all-powerful) 2. God exists, and is omnibenevolent (all-good) 3. God exists, and is omniscient (all-knowing) 4. Evil (...) exists Christian thinkers over the past two thousand years have given various responses to the problem of evil in the form of various theodicies, or attempts to explain why evil exists (or appears to exist) given the existence of an Omniscient, Omnipotent, Omnibenevolent God. This document serves as a brief overview of different theodicies offered by Christian thinkers throughout history. (shrink)

In this paper, I wish to criticize the notion that consensus is an epistemology. While I have never seen it explicitly claimed that “consensus is an epistemology,” I have nonetheless seen it implied in many scholarly (and layperson) articles. This occurs whenever articles cite, “a majority of scholars agree that…” or “most scientists/researchers think…” In our democratic, individualistic society, we put a value on high value votes and the quantification of majority viewpoints, whether it be in political polls (due to (...) living in a democracy), online on websites with ranking or voting systems such as Reddit, YouTube, or Instagram. The danger here is we may defer too much to the consensus view without appropriate justification. I will give several reasons why we should be skeptical of appeals to consensus (including a consensus of experts), which include its non-obvious link to ontology, the fact that consensus changes, and a lack of specificity of who counts as an ``expert,'' the lack of specificity on how to handle consensus (if it does occur), and epistemic undercutting defeaters from evolutionary epistemology. While an appeal to consensus may not tell us much about whether a theory is true, they can give us practical or pragmatic reasons for trusting a position. (shrink)

In this article, I define a cultural epistemology as a set of socially reinforced assumptions about how knowledge and truth are produced. Unlike a philosophical epistemology, a cultural epistemology is largely the product of culture and largely invisible. As products of culture, cultural epistemology are relatively unquestioned and, in many cases, philosophically unsophisticated. There are three common types of cultural epistemologies, influenced by who holds power in a given society: an epistemological monarchy, an epistemological oligarchy and an epistemological democracy. A (...) given cultural epistemology subsequently influences the legitimacy of culture and government itself. I argue argue that Americans tend to hold an "epistemological democracy" with two distinct facets: a trust in consensus, linked to living in a democratic republic, and a trust in their own self-interest, linked to market economics and capitalism more generally. These two facets combine, interact, and even oppose each other to legitimize and challenge American culture and its political and economic systems. (shrink)

This work deals with problems involving infinities and infinitesimals. It explores the ideas behind zero, its relationship to ontological nothingness, finititude (such as finite numbers and quantities), and the infinite. The idea of infinity and zero are closely related, despite what many perceive as an intuitive inverse relationship. The symbol 0 generally refers to nothingness, whereas the symbol infinity refers to ``so much'' that it cannot be quantified or captured. The notion of finititude rests somewhere between complete nothingness and something (...) having no end. -/- My concern is that many of the philosophers arguing for or against the ontology (or possibility) of an actual infinite set are unaware or unfamiliar with the mathematical literature attempting to clearly and rigorously define these terms. I believe it is a mistake to leave mathematicians out of this conversation, as analysts in particular have defined (and used) infinity in a way that is relevant to the ongoing debate between philosophers. -/- For this paper, I have selected examples from Principles of Analysis by Walter Rudin, which has become a standard text for Real Analysis classes taken by pure mathematicians and engineers. I will also restrict the scope of examples to Euclidean spaces for simplicity. Finally, I will be using addition, + and multiplication * in their usual way. (shrink)

The way citizens regard and treat one another in everyday life, even when they are not engaged in straightforwardly “political” activities, matters for achieving democratic ideals. This claim provokes an underexamined unease in many. Here I articulate these concerns, which I argue are prompted by the approaches most often associated with these issues. Such theories, like democratic communitarianism, require problematic sorts of unity in everyday social life. To avoid these difficulties, I offer an alternative, called procedural democratic informal politics, which (...) allows democrats to evaluate everyday life without demanding questionable forms of unity within it.

This paper explains how to use a new software tool for argument diagramming available free on the Internet, showing especially how it can be used in the classroom to enhance critical thinking in philosophy.

A key feature is the support for argumentation schemes, common patterns of defeasible reasoning historically know as (...) topics . Several examples are presented, as well as the results of an experiment in using the system with students in a university classroom. (shrink)

According to one large family of views, scientific explanations explain a phenomenon (such as an event or a regularity) by subsuming it under a general representation, model, prototype, or schema (see Bechtel, W., & Abrahamsen, A. (2005). Explanation: A mechanist alternative. Studies in History and Philosophy of Biological and Biomedical Sciences, 36(2), 421–441; Churchland, P. M. (1989). A neurocomputational perspective: The nature of mind and the structure of science. Cambridge: MIT Press; Darden (2006); Hempel, C. G. (1965). Aspects of scientific (...) explanation. In C. G. Hempel (Ed.), Aspects of scientific explanation (pp. 331–496). New York: Free Press; Kitcher (1989); Machamer, P., Darden, L., & Craver, C. F. (2000). Thinking about mechanisms. Philosophy of Science, 67(1), 1–25). My concern is with the minimal suggestion that an adequate philosophical theory of scientific explanation can limit its attention to the format or structure with which theories are represented. The representational subsumption view is a plausible hypothesis about the psychology of understanding. It is also a plausible claim about how scientists present their knowledge to the world. However, one cannot address the central questions for a philosophical theory of scientific explanation without turning one’s attention from the structure of representations to the basic commitments about the worldly structures that plausibly count as explanatory. A philosophical theory of scientific explanation should achieve two goals. The first is explanatory demarcation. It should show how explanation relates with other scientific achievements, such as control, description, measurement, prediction, and taxonomy. The second is explanatory normativity. It should say when putative explanations succeed and fail. One cannot achieve these goals without undertaking commitments about the kinds of ontic structures that plausibly count as explanatory. Representations convey explanatory information about a phenomenon when and only when they describe the ontic explanations for those phenomena. (shrink)

Effective altruism is a movement which aims to maximise good. Effective altruists are concerned with extreme poverty and many of them think that individuals have an obligation to donate to effective charities to alleviate extreme poverty. Their reasoning, which I will scrutinise, is as follows: -/- Premise 1. Extreme poverty is very bad. -/- Premise 2. If it is in our power to prevent something very bad from happening, without thereby sacrificing anything else morally significant, we ought, morally, to do (...) it. -/- Premise 3. Individuals ought to choose the effective option in preventing very bad things. -/- Premise 4. Donating to effective charities is one of the best ways to alleviate extreme poverty. -/- Conclusion. Individuals ought to donate to effective charities working towards extreme poverty alleviation where doing so does not require them to give up anything of moral significance. -/- I will scrutinise each of these premises in turn. -/- For Premise 1, I focus on hedonistic utilitarianism and criticise its outlook on extreme poverty. I claim that hedonistic utilitarianism might be problematic for effective altruism. -/- Premise 2 is Peter Singer's Weaker Principle of Sacrifice. I introduce several possible interpretations of it, and press several objections to it by stressing overpermissiveness, luck, and rights. I defend strengthening the Weaker Principle of Sacrifice without making it overdemanding. -/- I claim that Premise 3 can be attractive to both consequentialists and non-consequentialists. Nevertheless, by showing that effectiveness sometimes violates fairness, I propose a method which avoids always helping the greater number and always giving everyone equal chances of being helped, which is compatible with effective altruism. -/- Against Premise 4, I assess the systemic change objection, which states that effective altruism unjustifiably distracts individuals from systemic change. By considering risk and the moral standing of the future extremely poor, I claim that the systemic change objection is partially successful, but cannot undermine effective altruism. -/- After analysing all of these, I argue that individuals have an obligation to donate to effective charities to alleviate extreme poverty where doing so does not require them to give up anything of moral significance.

Suicide or self-destruction means in ordinary language “the act of killing oneself deliberately” (intentionally or on purpose). Indeed, that’s what we read in the Oxford dictionary and the Oxford dictionary of philosophy , which seems to be confirmed by the etymology of the term “suicide”, a term introduced around mid-17th century deduced from the modern Latin suicidium, ‘act of suicide’. Traditionally, suicide was regarded as immoral, irreligious and illegal in Western culture. However, during the 17th century this Christian view started (...) to change as a consequence of the rise of modern science . Generally speaking, Spinoza does not write much on death. His name does even not occur in the Oxford Philosophy of Death, although he had had very particular ideas on the nature of death. However, he even had much more particular ideas on suicide. Moreover, he states in the fourth proposition of the third part of his masterpiece, the Ethics, that self-destruction is simply impossible: Nulla res, nisi à causâ externâ, potest destrui. (shrink)

Robert Kimball, in “What’s Wrong with Argumentum Ad Baculum?” (Argumentation, 2006) argues that dialogue-based models of rational argumentation do not satisfactorily account for what is objectionable about more malicious uses of threats encountered in some ad baculum arguments.

For years, the European world saw millions of swans, and all of them without exception were white. If inductive reasoning is valid, one may conclude that all swans are white. However, this would be incorrect: in 1667 Dutch explorer Willem de Vlamingh observed black swans in Australia, falsifying the hypothesis that all swans are white. While often used as a cautionary tale for the use of induction, such as with Popper’s falsification principle, I want to explore a slightly different idea: (...) does the existence of fabricated or otherwise failed accounts of Black swans give me a reason to ignore future arguments or doubt their existence? I argue that while faulty or fabricated reports do not give us a logical reason to reject a claim, they can give us a practical one for refusing to consider future arguments. This practical vs logical distinction gives an inductive reason for believing that future arguments will be invalid, but keeps one from being able to necessarily deny the claim in question without further argumentation.

The process of cooperative problem solving can be divided into four stages. First, finding potential team members, then forming a team followed by constructing a plan for that team. Finally, the plan is executed by the team. Traditionally, very simple protocols like the Contract Net protocol are used for performing the first two stages of the process. In an open environment however, there can be discussion among the agents in order to form a team that can achieve the collective intention (...) of solving the problem. For these cases fixed protocols like contract net do not suffice. In this paper we present an alternative solution, using structured dialogues, with an emphasis on persuasion, that can be shown to lead to the required team formation. The dialogues are described formally using modal logics and speech acts. (shrink)

Abortion bans have been characterized as cruel especially in not allowing exceptions for rape or incest. The article first examines one approach to morally justifying bans based on the Doctrine of Double Effect (DDE) which distinguishes morally between killing or letting die intending death versus doing so only foreseeing death. It then presents some criticisms of the implications of the DDE but also argues that what the doctrine permits helps provide a ground for the permissibility of abortions even if the (...) fetus is a person. Whether there are limits on applying this argument is also considered. In conclusion, the article considers whether and why not permitting exceptions to bans for rape and incest is cruel and whether cruelty is a ground for opposition to bans. (shrink)

This paper recommends recognition theory as one useful tool in the diagnosis of the recent rise in two pathologies of democracy, specifically the surging success of populist politicians and parties across many consolidated democracies, and, increases in the social polarization of citizens along partisan lines in several of those nations. It begins by defining and discussing the resurgence of populism in two forms, before turning to a discussion of the concurrent increase in partisan polarization that is puzzlingly unconnected to policy (...) polarization. It then argues that recognition theory does a better job explaining these phenomena than alternative approaches by tying together social changes, moral psychology, and politically powerful social dynamics of identity, in a way that is sensitive to historical changes in recognition orders. It also argues that recognition theory provides an understanding of the specific political psychology supporting populism and polarization that does not treat supporters as mere passive victims of blind emotion, but rather as motivated by distinctly moral experiences of misrecognition and as making claims for recognition to the broader society. In the end, the paper suggests that a central causal role behind populism and polarization must be assigned to responses to a changing recognition order, especially where those enter into a fateful reinforcing causal dynamic with other economic and political causes, potentially turning the engaged use of democratic political freedom into its opposite.

Western, secularized capitalism appraises the “worth” of a worker through a wage, a numerical value assumed to reflect the value of one’s time (in the case of hourly jobs) or contribution (in the case of salary or commision-based work). Computers and AI models are capable of matching and even exceeding human performance on a variety of tasks such as mathematical computation, handwritten digit recognition, and even complex tasks such as playing the game Go. Furthermore, they can work around the clock (...) with no need for sleep, healthcare, or even a salary. As a result, computers are more “valuable” than humans under capitalism because they are more productive (in terms of quantity and, in many cases, quality of work). Combined with an erosion of the religious idea of explicit human worth or dignity, other humans are seen as mere means to the ends of those powerful enough to exploit them. Any hope of reducing inequality or promoting justice must come from an explicit belief in the “value” of human life independent of his or her ability to produce. (shrink)

While increasing attention has been paid in recent years to the relation between Foucault’s conception of critique and Kant’s, much controversy remains over whether Foucault’s most sustained early engagement with Kant, his dissertation on Kant’s Anthropology, should be read as a wholesale rejection of Kant’s views or as the source of Foucault’s late return to ethics and critique. In this paper, I propose a new reading of the dissertation, considering it alongside 1950s-era archival materials of which I advance the first (...) scholarly appraisal. I argue that Foucault manifests a fundamental ambivalence to Kantian anthropology, rejecting it in theoretical terms while embracing its practical (‘pragmatic’) conception of the subject. Furthermore, I take these texts to collectively evidence Foucault’s attempt to situate himself within the anthropological-critical tradition rather than extricating himself from it. If we interpret Foucault to reject this tradition’s appeal to an essentialized, theoretical conception of subjectivity, what remains of anthropology is its inherent practical reflexivity in structure. Thus, I situate Foucault’s conception of ethics as one’s relation to oneself in continuity with this tradition. (shrink)

Neuroscience has studied deductive reasoning over the last 20 years under the assumption that deductive inferences are not only de jure but also de facto distinct from other forms of inference. The objective of this research is to verify if logically valid deductions leave any cerebral electrical trait that is distinct from the trait left by non-valid deductions. 23 subjects with an average age of 20.35 years were registered with MEG and placed into a two conditions paradigm (100 trials for (...) each condition) which each presented the exact same relational complexity (same variables and content) but had distinct logical complexity. Both conditions show the same electromagnetic components (P3, N4) in the early temporal window (250–525 ms) and P6 in the late temporal window (500–775 ms). The significant activity in both valid and invalid conditions is found in sensors from medial prefrontal regions, probably corresponding to the ACC or to the medial prefrontal cortex. The amplitude and intensity of valid deductions is significantly lower in both temporal windows (p = 0.0003). The reaction time was 54.37% slower in the valid condition. Validity leaves a minimal but measurable hypoactive electrical trait in brain processing. The minor electrical demand is attributable to the recursive and automatable character of valid deductions, suggesting a physical indicator of computational deductive properties. It is hypothesized that all valid deductions are recursive and hypoactive. (shrink)

In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, and actually (...) restricts itself to justifying the tridimensionality of extension. (shrink)

If you utter sentence (1) ‘Obama was born in 1961’ now, you say something true about the past. Since the past will always be such that the year 1961 has the property of being a time in which Obama was born, it seems impossible that could ever be false in a future context of utterance. We shall consider the case of a sentence about the past exactly like (1), but which was true when uttered a few years ago and is (...) no longer true now. On this basis, we shall conclude that the past has changed. (shrink)

Eastern philosophy and western science have convergent and divergent viewpoints for their explanation of consciousness. Convergence is found for the practice of meditation allowing besides a time dependent consciousness, the experience of a timeless consciousness and its beneficial effect on psychological wellbeing and medical improvements, which are confirmed by multiple scientific publications. Theories of quantum mechanics with non-locality and timelessness also show astonishing correlation to eastern philosophy, such as the theory of Penrose-Hameroff (ORC-OR), which explains consciousness by reduction of quantum (...) superposition in the brain. Divergence appears in the interpretation of the subjective experience of timeless consciousness. In eastern philosophy, meditation at a higher level of awareness allows the personal experience of timeless and non-dual consciousness, considered as an empirical proof for the existence of pure consciousness or spirituality existing before the material world and creating it by design. Western science acknowledges the subjective, non-dual experience, and its multiple beneficial effects, however, the interpretation of spirituality designing the material universe is in disagreement with the Darwinian Theory of mutation and selection. A design should create an ideal universe without the injustice of 3% congenital birth defects and later genetic health problems. The western viewpoint of selection is more adapted to explain congenital errors. The gap between subjectivity and objectivity, the mind-body problem, is in eastern philosophy reduced to the dominance of subjectivity over objectivity, whereas western science attributes equal values to both. Nevertheless, there remains an astonishing complementarity between eastern and western practices. (shrink)

Given the growing interest in entrepreneurship education and the quest to provide entrepreneurial skills to all including the youths, the study investigates high school learners’ interest and readiness to start a business in South Africa. A group of high school learners (n=403) from select high schools in Cape Town was purposively sampled using self-administrated questionnaires while personal interviews were held with all Business Studies teachers in the participating schools (n=9). The results of this study indicate that 52% of the learners (...) are interested in starting a business, while 73% of them were from moderate income schools. A chi square test was performed to determine if the race and income level of the school influenced learners’ responses, and we found no statistical significance (P > 0.01). An overwhelming majority of the learners (73%) was of the view that they could start a business with the help of the knowledge and skills gained in the entrepreneurship education received. Suggestions on how to increase high school learners’ entrepreneurial intent and readiness to start a business upon leaving high school include the implementation of frequent learner visits to businesses as well as inviting entrepreneurs to give talks to learners. The goal of any scientific social enquiry such as the one pursued in this study, is to produce knowledge that assists in distilling viewpoints that express accurate necessities for socioeconomic development. Therefore, the practical implications of the study reside in the reinforcement of the need for a curriculum that addresses entrepreneurship education in South African high schools. -/- . (shrink)

Existing research suggests that people's judgments of actual causation can be influenced by the degree to which they regard certain events as normal. We develop an explanation for this phenomenon that draws on standard tools from the literature on graphical causal models and, in particular, on the idea of probabilistic sampling. Using these tools, we propose a new measure of actual causal strength. This measure accurately captures three effects of normality on causal judgment that have been observed in existing studies. (...) More importantly, the measure predicts a new effect ("abnormal deflation"). Two studies show that people's judgments do, in fact, show this new effect. Taken together, the patterns of people's causal judgments thereby provide support for the proposed explanation. (shrink)

In this paper, I will argue for a complex of three theses. First, that the problem of deep disagreement is an instance of the regress problem of justification. Second, that the problem of deep disagreement, as a regress problem, depends on a dialecticality requirement for arguments. Third, that the dialecticality requirement is plausible and defensible.

Epistemic infinitism is the view that infinite series of inferential relations are productive of epistemic justification. Peirce is explicitly infinitist in his early work, namely his 1868 series of articles. Further, Peirce's semiotic categories of firsts, seconds, and thirds favors a mixed theory of justification. The conclusion is that Peirce was an infinitist, and particularly, what I will term an impure infinitist. However, the prospects for Peirce's infinitism depend entirely on the prospects for Peirce's early semantics, which are not good. (...) Peirce himself revised the semantic theory later, and in so doing, it seems also his epistemic infinitism. (shrink)

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations in the paper.
