Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This paper reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subaltern forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

Review of David Ludwig, Inkeri Koskinen, Zinhle Mncube, Luana Poliseli, and Luis Reyes-Galindo, eds. Global Epistemologies and Philosophies of Science. Routledge, 2021, pp.i-xviii+319.

My dissertation is in two parts. First, it develops a philosophical concept of “tragic uncertainty,” derived from early twentieth-century Spanish philosopher Miguel de Unamuno. Secondly, it demonstrates ethical application of tragic uncertainty to human societal events. The ethical imperative created from tragic uncertainty—and not either tragedy or uncertainty alone—is the following. Given a tragic situation with a great degree of uncertainty, people living with doubt, mental despair, and perpetual anguish because of it should be provided relief. Generally, this relief should (...) be in the form of therapy, by which I mean an affective and emotional release. Two important case studies are explored. One on corrupted political systems in the USA-Mexico border. The other in Honduras, on both climate change and corrupted political systems. These are explained and categorized as tragically uncertain. Corresponding, minimal practical solutions accompany the ethical imperative created to remedy tragic uncertainty. (shrink)

This paper investigates the differences between ancient Greek and modern ethical naturalism, through the account of the whole classical tradition provided by Cicero in De finibus bonorum et malorum. Ever since Hume’s remarks on the topic, it is usually held that derivations of normative claims from factual claims require some kind of proper justification. It ́s a the presence of such justifications in the Epicurean, Stoic, and Academic-Peripatetic ethical theories (as portrayed in De finibus), and, after a negative conclusion, I (...) argue that we should conceive of this issue within a social-historical perspective: The radical difference between ancient and modern naturalistic ethics is due (in Weber’s terms) to the rationalization processes that generated the modern outlook on nature.

Speech Acts, Criteria and Intentions What makes a speech act a speech act? Which are its necessary and sufficient conditions? I claim in this paper that we cannot find an answer to those questions in Austin's doctrine of the infelicities, since some infelicities take place in fully committing speech acts, whereas others prevent the utterance from being considered as a speech act at all. With this qualification in mind, I argue against the idea that intentions—considered as mental states accomplishing a (...) causal role in the performance of the act—should be considered among the necessary conditions of speech acts. I would thus like to deny a merely ‘symptomatic’ account of intentions, according to which we could never make anything but fallible hypotheses about the effective occurrence of any speech act. I propose an alternative ‘criterial’ account of the role of intentions in speech acts theory, and analyse Austin's and Searle's approaches in the light of this Wittgensteinian concept. Whether we consider, with Austin, that speech acts ‘imply’ mental states or, with Searle, that they ‘express’ them, we could only make sense of this idea if we considered utterances as criteria for intentions, and not as alleged behavioural effects of hidden mental causes.

Death across human history is codified and controlled by religion, dogma, or social￾political circumstances. However, it is possible to take death out of these realms, instead dying how one wishes. One can design their own death. I will argue that human trans-death can be an intentional performance by persons and that this intentional performance can be combined with the newest and most novel methods of preserving a consciousness. This thesis opens possibilities for future exhibitions and live performances combining art and (...) innovative post-life, post-mortem (what I call “trans-death”) technologies. Possible performances or exhibitions combining art and innovative trans-death technologies include: people doing staged-performances while in their last years of life about their deanimation; public display of cryonically suspended (vitrified) bodies; and if consciousness is ever able to be digitized, the possibilities expand to any number of scenarios explored in anime shows and sci-fi literature or movies. The ethical and political implications of permissibility, freedom, and societal consequences of such artistic and technological expressions are not detailed, but some positions are outlined. A case study is utilized: the last years of life of famous and controversial Timothy Leary (1920-1996) and his struggle with prostate cancer. My analysis of the life and work of Timothy Leary - especially the text he mostly wrote Design for Dying (1997), it was edited by R.U. Sirius - is my theoretical foundation. (shrink)

El estudio de los "cardinales grandes" es uno de los principales temas de investigación de la teoría de conjuntos y de la teoría de modelos que ha contribuido con el desarrollo de dichas disciplinas. Existe una gran variedad de tales cardinales, por ejemplo cardinales inaccesibles, débilmente compactos, Ramsey, medibles, supercompactos, etc. Tres valiosos teoremas clásicos sobre cardinales medibles son los siguientes: (i) compacidad débil, (ii) Si κ es un cardinal medible, entonces κ es un cardinal inaccesible y existen κ cardinales (...) inaccesibles menores que κ , y (iii) Si existe un cardinal medible, entonces el axioma de constructibilidad (V=L) es falso. El objetivo de este artículo es presentar una demostración de cada uno de estos tres teoremas en el contexto de la teoría de modelos usando ideas del texto de Chang y Keisler (Model Theory). Tales demostraciones tienen en común el uso del método de construcción de modelos llamado ultraproductos, de lógicas infinitarias o fragmentos de la lógica de segundo orden, y del axioma de elección. Cardinales grandes y/o ultraproductos son importantes en teoría de conjuntos, teoría de modelos, análisis matemático, teoría de la medida, probabilidades, topología, análisis funcional, física, teoría de números, finanzas, etc. (shrink)

Are philosophy and literature allies or enemies in Jorge Luis Borges's fictions? In this paper, I argue that Borges can satisfy membership in the allies camp because his fictions provide the imaginative scenarios the allies believe are so necessary to this coalition; however, because his stories question philosophy's hold on reality, they can also seem to fall into the enemies camp by countervailing any claim philosophy has on reality and truth; although, ultimately, the manner in which Borges forges an (...) alliance between philosophy and literature will be for reasons not traditionally accepted by those in either the allies or enemies camps.

SINGULARITY: 12 Precepts for Transcendental Living | © 2022 Cromwell Black Publishing House | Original work by Luis Herrera. -/- Living transcendentally is not the same as ‘having the answers to life.’ The intention with which this book is written is to help you identify the God within yourself. Religion is a guidepost, but not the answer. Philosophy is a guidepost, not the answer. People that over-identify with one group or tribe for ideological reasons invariably meet with disappointment because (...) there will always be some tenets they internally oppose and disagree with. Yet they ignore their inner voice in order to ‘fit in with the rest.’ Man is a social animal and excommunication from the tribe has been tantamount to extinction of our lineage since our days as hunters and gatherers. By living transcendentally I have learned to acknowledge, welcome and accept the space between myself and my tribe. I invite you to do the same. -/- Learning to listen to the God within, I can trust my inner voice more because there is a message spoken there, uniquely for me, that will never be printed on the pages of the Bible, or the Koran, or the Tao Te Ching, or any other book for that matter. There’s only one YOU. Others may have your name, but not your identity. They may share your birth date and hospital, but not your parents. They may share your parents, but not your name. Do you see what I’m getting at here? Therefore how can a ‘one-size fits all’ religion, education or philosophy possibly answer the question to your meaning of life? There is no the meaning of life, because there is no the life. There are infinite lives, for which infinite meanings must be furnished. Hence the importance of learning to trust yourself, your inner voice, conscience – the God within. (shrink)

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

The gulf between philosophical and formal ontology can and should be bridged. In this Editorial, I elaborate briefly on this subject.

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of knowledge (SoK) and additionally distinguishes (...) knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

Knowledge representation (KR) is actually more than representation: It involves also inference, namely inference of “new” knowledge, i.e. new facts. Logic programming is a suitable KR medium, but more often than not discussions on this programming paradigm focus on aspects other than KR. In this paper, I elaborate on the general theory of logic programming and give the essentials of two of its main implementations, to wit, Prolog and Datalog, from the viewpoint of deductive computing over knowledge bases, which includes (...) deductive programming.

The van Wijngaarden grammars are two-level grammars that present many interesting properties. In the present article I elaborate on six of these properties, to wit, (i) their being constituted by two grammars, (ii) their ability to generate (possibly infinitely many) strict languages and their own metalanguage, (iii) their context-sensitivity, (iv) their high descriptive power, (v) their productivity, or the ability to generate an infinite number of production rules, and (vi) their equivalence with the unrestricted, or Type-0, Chomsky grammars.

Skeptical theism, broadly construed, is an attempt to leverage our limited cognitive powers, in some specified sense, against “evidential” and “explanatory” arguments from evil. Since there are different versions of these kinds of arguments, there are correspondingly different versions of skeptical theism. In this paper, I consider four challenges to three central versions of skeptical theism: (a) the problem of generalized skepticism, (b) the problem of moral skepticism, (c) the problem of unqualified modal skepticism, and (d) the challenge from Bayesian (...) epistemology.

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets (...) and reported findings.

Ever since John Locke, philosophers have discussed the possibility of a normative epistemology: are there epistemic obligations binding the cognitive economy of belief and disbelief? Locke's influential answer was evidentialist: we have an epistemic obligation to believe in accordance with our evidence. In this dissertation, I place the contemporary literature on agency and reasons at the service of some such normative epistemology. I discuss the semantics of obligations, the connection between obligations and reasons to believe, the implausibility of Lockean evidentialism, (...) and some of the alleged connections between agency and justification. (shrink)

Paul Silva has recently argued that doxastic justification does not have a basing requirement. An important part of his argument depends on the assumption that doxastic and moral permissibility have a parallel structure. I here reply to Silva's argument by challenging this assumption. I claim that moral permissibility is an agential notion, while doxastic permissibility is not. I then briefly explore the nature of these notions and briefly consider their implications for praise and blame.

The relations between ontology and information are many and fundamental, and they help us to understand the present gulf between (formal) ontology and (philosophical) Ontology: We can speak of respectively ontology-driven information and information-driven ontology as the focus on being informed vs. informed being. The question of whether these two (can) coincide is relevant to both fields, and in this article I elaborate on what needs to be addressed first of all to provide us with an answer: The form. This (...) core ontological concept rooting in Aristotelian metaphysics was central to philosophical ontology, in particular in Latin Scholasticism, when it was clearly put into relation with information as that which defines an entity. In this context, Dietrich of Freiberg synthesized this long debate in a way that matters not only to the philosophical effort of producing information-driven ontologies but also to the engineering constructs of ontology-driven information systems. (shrink)

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

To most of us – believers and non-believers alike – the possibility of a perfect God co-existing with the kinds of evil that we see calls out for explanation. It is unsurprising, therefore, that the belief that God must have justifying reasons for allowing all the evil that we see has been a perennial feature of theistic thought. Recently, however, a growing number of authors have argued that the existence of a perfect God is compatible with the existence of gratuitous (...) evil. Given powerful, millenia-long sensibilities about power and love and justice, it isn’t hard to find that suggestion simply incredible. Nonetheless, in this paper I will argue that the most prominent theistic alternatives to what has seemed incredible to most of us throughout most of history are themselves patently unacceptable for the theist as well. On any of the most widely accepted accounts of how God could have justifying reasons for permitting some evils, God’s existence means that we have justifying reasons for perpetrating and allowing every evil that we see. That's hard to swallow too. If I’m right about all of this, then two competing outcomes seem to present themselves as a possible result. On the one hand, for the theist, the apparently outrageous suggestion that the existence of a perfect God is compatible with gratuitous evil no longer looks like it faces a formidable, hard-to-resist alternative. On the other hand, some like me might think that my arguments go no distance at all towards dispelling the incredibility of the gratuitous evil nouvelle vague. On this line, theism may seem now to be between the rock and the hard place: it seems hard to make sense of the existence of a perfect God whether or not He has justifying reasons for allowing all the evil that we see.

2nd edition. Many-valued logics are those logics that have more than the two classical truth values, to wit, true and false; in fact, they can have from three to infinitely many truth values. This property, together with truth-functionality, provides a powerful formalism to reason in settings where classical logic—as well as other non-classical logics—is of no avail. Indeed, originally motivated by philosophical concerns, these logics soon proved relevant for a plethora of applications ranging from switching theory to cognitive modeling, and (...) they are today in more demand than ever, due to the realization that inconsistency and vagueness in knowledge bases and information processes are not only inevitable and acceptable, but also perhaps welcome. The main modern applications of (any) logic are to be found in the digital computer, and we thus require the practical knowledge how to computerize—which also means automate—decisions (i.e. reasoning) in many-valued logics. This, in turn, necessitates a mathematical foundation for these logics. This book provides both these mathematical foundation and practical knowledge in a rigorous, yet accessible, text, while at the same time situating these logics in the context of the satisfiability problem (SAT) and automated deduction. The main text is complemented with a large selection of exercises, a plus for the reader wishing to not only learn about, but also do something with, many-valued logics. (shrink)

Deontological evidentialism is the claim that we ought to form and maintain our beliefs in accordance with our evidence. In this paper, I criticize two arguments in its defense. I begin by discussing Berit Broogard’s use of the distinction between narrow-scope and wide-scope requirements against W.K. Clifford’s moral defense of. I then use this very distinction against a defense of inspired by Stephen Grimm’s more recent claims about the moral source of epistemic normativity. I use this distinction once again to (...) argue that Hilary Kornblith’s criticism of Richard Feldman’s defense of is incomplete. Finally, I argue that Feldman’s defense is insensitive to the relation between normative requirements and privileged values: values that have normative authority over us. (shrink)

In Leibniz’s New Essays stands out, within many important topics, his doctrine of innate ideas, which supposes the division between sense knowledge and innate knowledge and implies the distinction between truths of reason and truths of fact. That doctrine is particularly relevant for Leibniz’s philosophy, but implicitly entails the epistemological difference between belief, on one hand, and certainty, on the other. In this paper I outline, according to my interpretation, how Leibniz explains that humans can have certainty about innate ideas. (...) This topic is important because if Leibniz demonstrates the possibility of having certainty of those ideas, then, it is feasible to believe in its existence. However, if his explanation is unsatisfactory his metaphysical doctrine would be seriously weakened and, at the same time, both skepticism and Locke’s empiricist doctrine would be reinforced.

In this paper I present reasons for us to accept the hypothesis that suspended judgment has correctness conditions, just like beliefs do. Roughly put, the idea is that suspended judgment about p is correct when both p and ¬p might be true in view of certain facts that characterize the subject’s situation. The reasons to accept that hypothesis are broadly theoretical ones: it adds unifying power to our epistemological theories, it delivers good and conservative consequences, and it allows us to (...) assess processes of reasoning involving attitudes of suspended judgment.

Logic has been a—disputed—ingredient in the emergence and development of the now very large field known as knowledge representation and reasoning. In this book (in progress), I select some central topics in this highly fruitful, albeit controversial, association (e.g., non-monotonic reasoning, implicit belief, logical omniscience, closed world assumption), identifying their sources and analyzing/explaining their elaboration in highly influential published work.

Readers and historians have often misunderstood Berkeley's philosophy by believing that he denies the existence of the external world. From which they conclude that his philosophy inevitably leads to solipsism. Faced with these readings, in this paper I discuss the relationship between ontology and the external world in Berkeley with the aim of clarifying some interpretative errors and showing three things: 1) that is a mistake to believe Berkeley’s philosophy eliminate the external world and lead to solipsism, 2) that his (...) own ontology is the key to understand the constitution of the external world, and 3) that God gives the ultimate meaning of that world. / Es habitual que algunos lectores confundan la postura de Berkeley al creer que niega la existencia del mundo externo y que su filosofía lleva inevitablemente al solipsismo. Frente a estas lecturas, analizo en este artículo el tema de la relación entre ontología y mundo externo en Berkeley, con el propósito de aclarar algunos desaciertos interpretativos sobre el asunto y mostrar con ello tres cosas: 1) que se trata de un error creer que su filosofía elimina el mundo externo y lleva al solipsismo, 2) que en la propia ontología está la clave para entender la constitución del mundo externo, y 3) que Dios le da el sentido último a ese mundo.

James Sterba has recently argued that the free will defense fails to explain the compossibility of a perfect God and the amount and degree of moral evil that we see. I think he is mistaken about this. I thus find myself in the awkward and unexpected position, as a non-theist myself, of defending the free will defense. In this paper, I will try to show that once we take care to focus on what the free will defense is trying to (...) accomplish, and by what means it tries to do so, we will see that Sterba’s criticism of it misses the mark.

Logic arguably plays a role in the normativity of reasoning. In particular, there are plausible norms of belief/disbelief whose antecedents are constituted by claims about what follows from what. But is logic also relevant to the normativity of agnostic attitudes? The question here is whether logical entailment also puts constraints on what kinds of things one can suspend judgment about. In this paper I address that question and I give a positive answer to it. In particular, I advance two logical (...) norms of agnosticism, where the first one allows us to assess situations in which the subject is agnostic about the conclusion of a valid argument and the second one allows us to assess situations in which the subject is agnostic about one of the premises of a valid argument.

Mauricio Beuchot proposed in his Treatise of Analogical hermeneutics (1997) a new interpretative model based on the ancient concept of "analogy".

This article advances the hypothesis that the Fichtean enterprise of grounding all possible experience in a fundamental principle has to fail in order to succeed one of its most important tasks: reformulating the very idea of subjectivity. In order to ground this hypothesis, the paper will be divided in four parts: (i) the first one will analyze the starting point of the work where Fichte lays the foundations of his philosophical project (Grundlage der gesamten Wissenschaftslehre) so as to show that (...) its first principle contains a fundamental ambiguity. We will then (ii) suggest that this very ambiguity reveals itself in the Anstoß, the conceptual tool through which Fichte intends to get rid of the Kantian notion of thing-in- itself. In a third moment (iii), we will explore the effects of this abandonment of the thing-in-itself on the relation between the finite and the infinite, what will bring us to the notion of failure. Finally (iv), we will propose to interpret this failure as a positive driving force of a permanent calling into question of the subject and its language. (shrink)

Deontological evidentialism is the claim that S ought to form or maintain S’s beliefs in accordance with S’s evidence. A promising argument for this view turns on the premise that consideration c is a normative reason for S to form or maintain a belief that p only if c is evidence that p is true. In this paper, I discuss the surprising relation between a recently influential argument for this key premise and the principle that ought implies can. I argue (...) that anyone who antecedently accepts or rejects this principle already has a reason to resist either this argument’s premises or its role in support of deontological evidentialism.

One of the few points of agreement between most theists and non-theists working on the problem of evil is that the existence of a perfect God is incompatible with the existence of pointless evil. In a series of influential papers, however, Peter van Inwagen has argued that careful attention to the reasoning behind this claim reveals fatal difficulties related to the Sorites Paradox. In this paper, I explain van Inwagen’s appeal to sorites reasoning, distinguish between two different arguments in his (...) work, and argue that they both commit the same so-far-unnoticed mistake.

Deontological internalism is the family of views where justification is a positive deontological appraisal of someone's epistemic agency: S is justified, that is, when S is blameless, praiseworthy, or responsible in believing that p. Brian Weatherson discusses very briefly how a plausible principle of ampliative transmission reveals a worry for versions of deontological internalism formulated in terms of epistemic blame. Weatherson denies, however, that similar principles reveal similar worries for other versions. I disagree. In this article, I argue that plausible (...) principles of ampliative transmission reveal a worry for deontological internalism in general. (shrink)

This paper defends a novel account of how to determine the intrinsic value of possible worlds. Section 1 argues that a highly intuitive and widely accepted account leads to undesirable consequences. Section 2 takes the first of two steps towards a novel account by clarifying and defending a view about value-contribution that is based on some of W. D. Ross’ claims about the value of pleasure. Section 3 takes the second step by clarifying and defending a view about value-suppression that (...) is based on Ross’ claims about the interplay between prima-facie duties. Section 4 states and defends the account that I call Rossian Totalism. According to this account, the atoms of intrinsic value within a world only sometimes contribute their intrinsic value to the value of that world. (shrink)

What I call the Doxastic Puzzle, is the impression that while each of these claims seems true, at least one of them must be false: (a) Claims of the form ‘S ought to have doxastic attitude D towards p at t’ are sometimes true at t, (b) If Φ-ing at t is not within S’s effective control at t, then it is false, at t, that ‘S ought to Φ at t’, (c) For all S, p, and t, having doxastic (...) attitude D towards p at t is not within S’s effective control at t. All three natural replies to the puzzle have been pursued. Some have claimed that doxastic attitudes like believing that p are, in fact, within our effective control, or sufficiently so. Others have claimed that doxastic ought-claims, strictly speaking, are always false. And some have denied that effective control is required for the adequacy of doxastic ought-claims in general. I here pursue and examine a different strategy. In the first part of this paper, I argue that these claims are not only each true but actually not in tension with each other in the first place. Instead of attempting to dispel the puzzle, this solution proposes to evade it instead: to solve it by properly understanding, and by thereby accepting without contradiction, all of its constitutive claims. In the second part of the paper, I argue that the evasive strategy forces us to re-think our understanding of the place of normative reasons in epistemology. More exactly, it seems to come at the cost of one central way of thinking about our reasons for having doxastic attitudes, one where such reasons are good-standing exemplars of normative reasons in general. The evasive strategy, that is, threatens to lead us very quickly to a deflationary picture of epistemic normativity: it rescues normative talk, but sacrifices normative substance. I conclude by explaining why I think this is more consequential than some have made it out to be, and by suggesting that these consequences are welcome nonetheless. (shrink)

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view successfully explains what is wrong with certain akratic doxastic states. In this paper I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all (...) of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment and credence. These explanations deploy the notions of knowledge and being in a position to know, instead of the notion of responding properly to the evidence. Finally, I suggest that this picture can be generalized to the realm of practical rationality as well. (shrink)

In this paper, I offer two counterexamples to the so-called ‘Uniqueness Thesis.’ As one of these examples rely on the thesis that it is possible for a justified belief to be based on an inconsistent body of evidence, I also offer reasons for this further thesis. On the assumption that doxastic justification entails propositional justification, the counterexamples seem to work.

Reasoning over our knowledge bases and theories often requires non-deductive inferences, especially – but by no means only – when commonsense reasoning is the case, i.e. when practical agency is called for. This kind of reasoning can be adequately formalized via the notion of supraclassical consequence, a non-deductive consequence tightly associated with default and non-monotonic reasoning and featuring centrally in abductive, inductive, and probabilistic logical systems. In this paper, we analyze core concepts and problems of these systems in the light (...) of supraclassical consequence. (shrink)

All research is immersed in the competition for knowledge, but this is not always governed by fairness. In this opinion article, I elaborate on indicators of unfairness to be found in both evaluation guides and evaluation panels, and I spontaneously offer a number of rules of thumb meant to keep it at bay. Although they are explicitly offered to the Portuguese Foundation for Science and Technology (FCT) and in particular to the evaluation panel for Philosophy, Ethics and Religion of FCT's (...) fifth edition of their Individual Call to Scientific Employment Stimulus, here used as concrete illustrations of unfairness, my rules of thumb are guaranteed to promote fairness in the competition for knowledge in general.

Expressiveness and decidability are two core aspects of programming languages that should be thoroughly known by those who use them; this includes knowledge of their metalanguages a.k.a. formal grammars. The van Wijngaarden grammars (WGs) are capable of generating all the languages in the Chomsky hierarchy and beyond; this makes them a relevant tool in the design of (more) expressive programming languages. But this expressiveness comes at a very high cost: The syntax of WGs is extremely complex and the decision problem (...) for the generated languages is generally unsolvable. With this in mind, I provide here a short primer of the syntax of WGs, which includes syntactic restrictions that guarantee decidability for the corresponding generated languages. (shrink)

In this editorial, I explain how Paul Feyerabend's Principle of Proliferation is adopted and adapted as a publication model for the Journal of Knowledge Structures and Systems (JKSS). Critical views on the limitations of both non-dynamic publishing models and government- and industry-based models of research are expressed.

Science, technology, and professions form a system with strong interactions. Yet, these activities attack different kinds of problems which require different kinds of solutions. The problems that trigger scientific and technological research remain insufficiently solved or unsolved, therefore their possible solutions must be invented (i. e. they are partially or totally original) and, consequently, they should be tested against reality by researchers before considering them as true or useful. On the contrary, the problems that trigger professional inquiry are already solved, (...) or have at least some partial solution at hand that is available in the form of a technical protocol. This solution is applied with caution but without testing (i. e. the professional assumes that the solution works because it was already challenged by researchers). Moreover, science and technology tackle unsolved inverse problems, which allow the radical advancement of knowledge, and genuine innovation. A science policy based on a clear distinction between creative and routine activities (i. e. a cre- atively friendly policy) offers an opportunity for societies to reach value-added innovative economic and integral development.

My starting point is what I call the Normative Authority Conception of justification, where S is justified in their belief that p at t (to some degree n) if and only if their believing that p at t is not ruled out by epistemic norms that have normative authority over S at t. With this in mind, this paper develops an account of doxastic justification by first developing an account of the normative authority of epistemic norms. Drawing from work in (...) political philosophy, I argue that (a) the cognitive and evaluative commitments and concerns behind our actual practices of holding each other and ourselves accountable for our beliefs reveal which epistemic norms we have consented to be under, and that (b) it is because we have consented to be under the authority of these norms – by actually holding ourselves and others accountable to them – that they in turn have normative authority over us. By connecting the authority of epistemic norms to the authority we have over ourselves in this way, the resulting account of doxastic justification (i) explains why it can be appropriate to criticize, resent, or sanction someone for having unjustified beliefs, (ii) avoids the phenomena of normative alienation and normative parochialism, and (iii) respects the social and collective nature of epistemic justification.

Cet article montre que Fichte développe une originelle conception du langage dans ses Discours à la Nation allemande d’où il ressort non seulement le besoin de retraduire des concepts philosophiques dans un langage populaire comme aussi celui de formuler un langage plus malléable pour la philosophie en tant que telle. Afin d’explorer cette hypothèse, notre propos suivra les étapes suivantes : (i) nous analyserons la conception fichtéenne du rapport entre popularisation et flexibilisation du langage, ce qui nous permettra (ii) d’explorer (...) les raisons systématiques du rapprochement entre langue philosophique et langue populaire et (iii) de saisir précisément la compréhension du rôle philosophique du langage qui en découle.

I reinforce my defense of permissivism about the rationality of doxastic attitudes on the face of a certain body of evidence against criticism published in this journal by Anantharaman. After making some conceptual clarifications, I manage to show that at least one of my original arguments pro-permissivism is left unscathed by Anantharaman's points.

Just started a new book. The aim is to establish a science of knowledge in the same way that we have a science of physics or a science of materials. This might appear as an overly ambitious, possibly arrogant, objective, but bear with me. On the day I am beginning to write it–June 7th, 2020–, I think I am in possession of a few things that will help me to achieve this objective. Again, bear with me. My aim is well (...) reflected in the title I chose (just now) for this book: Knowledge & Logic: Towards a science of knowledge. Its most important feature is that I shall take logic to be to knowledge science as calculus is to physics or to materials science. I do not intend to reclaim knowledge from the bosom of philosophy, in which, known as epistemology its erudite discussion has hardly progressed since Plato first defined it as true belief with logos. With only a few adjustments, it will actually provide me with the right, science-bound start. More recently, knowledge has been reclaimed by the field of BA, a reclaim that has opened the box of Pandora: Among the evils, and perhaps at the head of the list, is an overly lay, essentially naive, notion of knowledge. But the very idea that one can have something like “knowledge (management) software” puts us on the right track. (shrink)
