Belum begitu lama dua buah berita menggoncangkan dunia (astro-fisika). Yang pertama, CERN, Pusat penelitian atom di Geneva, yang dalam dua eksperimen berturut-turut menemukan bahwa neutrino (bagian mikro paling kecil) bergerak dengan kecepatan sedikit melampaui kecepatan cahaya. Yang kedua, pada minggu kedua Januari yang lalu pengamatan astronomis mutakhir menengarai bahwa dalam Bimasakti kita rata-rata setiap dari 10 milyar bintangnya mempunyai sekurang-kurangnya satu planet yang mirip dengan planet kita, bumi. Berita pertama begitu dahsyat sehingga para ahli fisika yang membuat eksperimen itu belum (...) mau mempercayainya, karena kalau amatan mereka betul, salah satu pilar fisika modern—teori relativitas khusus Einstein— runtuh. Sebuah revolusi baru dalam fisika. Salah satu implikasinya: kemungkinan menjalin komunikasi dengan extraterrestrial intelligence (ETI)—kalau ada—bertambah besar. Berita kedua lebih dahsyat lagi implikasinya. Sampai sekarang banyak astronom berpendapat bahwa probabilitas terjadinya planet dengan ciri-ciri seperti bumi adalah sedemikian kecil sehingga tidak mustahil kalau manusia merupakan satu-satunya makhluk berakal-budi di alam raya. Tetapi kalau di Bimasakti kita saja—satu di antara (diperkirakan) 1011 Bimasakti di seluruh alam raya—terdapat 10 milyar planet mirip bumi, adanya makhluk berakal budi di luar bumi (aliens) merupakan kemungkinan kuat. Dua penemuan ini mengangkat salah satu tantangan paling serius bagi teologi Kristiani: kalau ada makhluk berakal budi di tempat lain di alam raya, apa implikasinya bagi inti iman Kristiani, peristiwa Yesus Kristus? Apakah mereka juga perlu ditebus dari dosa? Dan kalau perlu, apakah karya penebusan Yesus juga berlaku bagi mereka? Kalau penyelamatan ilahi di planet-planet tidak berkaitan dengan Yesus Kristus, apa Yesus Kristus masih mempunyai relevansi universal dalam rencana penyelamatan ilahi? Pertanyaan-pertanyaan ini bukanlah pertanyaan iseng-iseng, melainkan menyangkut hakikat iman Kristiani. Persis masalah inilah yang dibahas oleh Armin Kreiner—guru besar teologi fundamental pada Fakultas Teologi Katolik Universitas München—dalam bukunya (yang, sayang, baru tersedia dalam bahasa Jerman). Buku ini membahas tantangan bagi teologi Kristiani andaikata ternyata selain manusia ada makhluk berakal budi lain di alam raya......................................... Apakah Kreiner berhasil menjawab pertanyaan-pertanyaan teologis berat yang diajukannya sendiri? Inti masalahnya adalah bagaimana dua keyakinan berikut dapat dipersatukan. Pertama, bahwa kalau ada ETI di alam raya, mereka tidak kurang dicintai oleh Allah dari pada manusia bumi dan karena itu inkarnasi ilahi tidak mungkin merupakan kejadian hanya di planet bumi. Kedua, bahwa dalam manusia Yesus Allah mewahyukan diri sendiri secara unik dengan makna penyelamatan universal. Dan hal itu perlu dijawab tanpa jatuh ke dalam pluralisme relativistik àla Knitter, Hick dan Schmidt-Leukel di mana Yesus hanyalah salah satu dari pewahyuan diri Allah yang pada hakikatnya semua sama derajatnya. Kiranya Kreiner berhasil merumuskan tantangan. Ia menunjukkan arah pemecahannya, tetapi ia belum memecahkannya. Bisa diteliti apakah pemecahan dapat dicari ke arah pemikiran baru tentang Pan-en-teisme sebagai pola yang lebih cocok untuk memahami hubungan antara Sang Pencipta dan ciptaan, sebagaimana akhir-akhir ini diangkat oleh beberapa teolog (Herderkorrespondenz Spezial 2-2011). Yang jelas, kemungkinan adanya aliens menghadapkan teologi Kristiani dengan tantangannya yang barangkali paling berat, yang sampai sekarang pernah dihadapinya. Sebagai catatan penutup, tetap benar bahwa probabilitas adanya ETI, melawan segala tulisan populer dan ilmiah (sampai sekarang), tetap minim! Probabilitas matematis bahwa di sebuah planet dengan kondisi-kondisi seperti bumi kita terjadi evolusi sampai ke kehidupan intelektual adalah kurang dari satu di antara 10100 (bdk. Erbrich, 1988, dll.). Kalaupun dalam setiap dari seluruh 1011 Bimasakti terdapat 10.000 planet mirip bumi, maka jumlah planet di alam raya yang kondisi-kondisinya mirip bumi adalah 1015. Jadi probabilitas adanya ETI tetap teramat rendah. Kemungkinan besar kita tidak pernah akan mengetahui apakah ada ETI. Selama itu pertimbangan-pertimbangan dramatis di atas bisa saja hanyalah sebuah permainan teologis, namun dengan daya tantang yang memang tinggi.

This investigation takes full account of the findings of the social and historical sciences while offering a religious interpretation of the religions as different culturally conditioned responses to a transcendent Divine Reality.

Tractatus 4.024 inspired the dominant semantics of our time: truth-conditional semantics. Such semantics is focused on possible worlds: the content of p is the set of worlds where p is true. It has become increasingly clear that such an account is, at best, defective: we need an ‘independent factor in meaning, constrained but not determined by truth-conditions’ (Yablo 2014, p. 2), because sentences can be differently true at the same possible worlds. I suggest a missing comment which, had it been (...) included in the Tractatus, would have helped semantics get this right from the start. This is my 4.0241: ‘Knowing what is the case if a sentence is true is knowing its ways of being true’: knowing a sentence’s truth possibilities and what we now call its topic, or subject matter. I show that the famous ‘fundamental thought’ that ‘the “logical constants” do not represent’ (4.0312) can be understood in terms of ways-based views of meaning. Such views also help with puzzling claims like 5.122: ‘If p follows from q, the sense of “p” is contained in the that of “q”’, which are compatible with a conception of entailment combining truth-preservation with the preservation of topicality, or of ways of being true.

Introduction and translation of “The Four Phases of Philosophy” by Franz Brentano.

John Hick is one of the most widely read and discussed living writers in modern theology and the philosophy of religion. This book offers students a one volume textbook on his thought. Extracts from his writings cover all the various themes for which Hick has become known: Faith and Knowledge, Philosophy of Religion, Evil and the God of Love, Death and Eternal Life, The Myth of God Incarnate, and Problems of Religious Pluralism. The extracts are preceded by an introductory essay (...) by Paul Badham on John Hick's philosophical theology, and on the integrity of his life and thought. (shrink)

In this book a leading philosopher of religion offers fresh insights into some of the disputed religious questions of our time.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it to (...) intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) (...) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (nonasymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

Unification was originally introduced in automated deduction and term rewriting, but has recently also found applications in other fields. In this article, we give a survey of the results on unification obtained in two closely related, yet different, application areas of unification: description logics and modal logics.

This book examines the concepts of international law and international relations as they are developed in the social and political philosophy of G.W.F. Hegel. Hegel has a vision of a single modern social world, in which peoples and nation-states can co-exist under conditions of peace, justice, mutual respect, and prosperity.

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally affected by environmental (...) factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

In this article 1 I have two theological interests and a less direct philosophical one.

The Description Logic Handbook covers all aspects of the research in the field of knowledge representation. Written by some of the most prominent researchers in the field, and covering the basic technical material and implementational aspects, it is both a unique reference and a self-study guide.

Unlike the first English translation in 1974, this edition contains the text corresponding to Brentano's original 1874 edition.

First published in 1969. Routledge is an imprint of Taylor & Francis, an informa company.

Condorcet's famous jury theorem reaches an optimistic conclusion on the correctness of majority decisions, based on two controversial premises about voters: they are competent and vote independently, in a technical sense. I carefully analyse these premises and show that: whether a premise is justi…ed depends on the notion of probability considered; none of the notions renders both premises simultaneously justi…ed. Under the perhaps most interesting notions, the independence assumption should be weakened.

We propose a new account of indicative conditionals, giving acceptability and logical closure conditions for them. We start from Adams’ Thesis: the claim that the acceptability of a simple indicative equals the corresponding conditional probability. The Thesis is widely endorsed, but arguably false and refuted by empirical research. To fix it, we submit, we need a relevance constraint: we accept a simple conditional 'If φ, then ψ' to the extent that (i) the conditional probability p(ψ|φ) is high, provided that (ii) (...) φ is relevant for ψ. How (i) should work is well-understood. It is (ii) that holds the key to improve our understanding of conditionals. Our account has (i) a probabilistic component, using Popper functions; (ii) a relevance component, given via an algebraic structure of topics or subject matters. We present a probabilistic logic for simple indicatives, and argue that its (in)validities are both theoretically desirable and in line with empirical results on how people reason with conditionals.

In dem Sammelband, der als Festschrift zum 65. Geburtstag von Franz Hundsnurscher erscheint, sind 47 Beiträge zu zwei thematischen Schwerpunkten versammelt, die im Werk Hundsnurschers von zentraler Bedeutung sind: Semantik und Dialoganalyse. Im ersten Teil werden neben grundlegenden Fragen der Semantik Aspekte der semantischen Beschreibung von Phraseologismen, des Fremdwortgebrauchs und des Grundwortschatzes diskutiert; neben synchronen (meist gebrauchstheoretischen) Untersuchungen zu Einzelwörtern und Quasisynonymengruppen im Deutschen stehen sprachhistorische und kontrastive Arbeiten. Vor allem mit theoretischen und methodologischen Fragen der Dialoganalyse, mit Fragen (...) der Analyse institutioneller Kommunikation (Politik, Recht, Wirtschaft) und literarischer Dialoge setzen sich die Beiträge des zweiten Teils auseinander.

Die Idee zu der in diesem Band dokumentierten Tagung ist im Rahmen des disziplinübergreifenden Nachwuchswissenschaftsnetzwerkes THESIS entstanden. Der Dialog über die fachlichen und disziplinären Grenzen hinweg hat bei THESIS seit dessen Gründung im Jahre 1990 stets einen großen Raum eingenommen. Anderen Fächern Respekt und Interesse entgegenzubringen und sich nicht von stereotypen Vorurteilen leiten zu lassen, ist konstitutiver Bestandteil im Selbstverständnis des Netzwerkes. Selbstverständlich gibt es in einem solchen Verbund eine Reihe von Gelegenheiten (darunter auch den einen oder anderen entwicklungsfördernden Konflikt), (...) das eigene Bild vom Anderen und das andere Bild vom Eigenen zur Sprache zu bringen und zu hinterfragen. Auf der Basis dieser bestehenden Kommunikationsstrukturen trafen sich am 11. Oktober 2003 in Göttingen 12 junge Wissenschaftlerinnen und Wissenschaftler zwischen, über und auch auf den Grenzen ihrer eigenen Herkunftsdisziplinen, um den Trendbegriff [alpha]Transdisziplinarität" auf seine Substanz zu prüfen.

We present an abstract model of rationality that focuses on structural properties of attitudes. Rationality requires coherence between your attitudes, such as your beliefs, values, and intentions. We define three 'logical' conditions on attitudes: consistency, completeness, and closedness. They parallel the familiar logical conditions on beliefs, but contrast with standard rationality conditions like preference transitivity. We establish a formal correspondence between our logical conditions and standard rationality conditions. Addressing John Broome's programme 'rationality through reasoning', we formally characterize how you can (...) (not) become more logical by reasoning. Our analysis connects rationality with logic, and enables logical talk about multi-attitude psychology. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

This essay critically examines economist and philosopher Amartya Sen's writings as a potential resource in religious ethicists' efforts to analyze discrimination against girls and women and to address their well-being and agency. Delineating how Sen's discussions of "missing women" and "gender and cooperative conflict" fit within his "capability approach" to economic and human development, the article explores how Sen's methodology employs empirical analysis toward normative ends. Those ends expand the capability of girls and women to function in all aspects of (...) their society. It concludes with a discussion of ways to engage Sen's work within religious ethics. (shrink)

Perceptions are often merely regarded as the basic elements of knowledge. They have, however, a complex structure of their own and are far from being elementary. My paper will analyze two basic patterns of perception and some of the resulting medical implications. Most basically, all object perception is characterized by a mixture of knowledge and ignorance (Husserl). Perception essentially perceives with inner and outer horizons, brought about by the kinesthetic activity of the perceiving subject (Sartre). This first layer of perceptual (...) reality, the world of open perceptions, is the inescapable background for every rationality, every value, every existence (Merleau-Ponty). On an epistemological level a characteristic change of perceptual patterns in medicine was introduced by pathological anatomy (Foucault). The reference of medical perception to the dead body created the new possibility of absolute perception, allowing for more precise medical interventions, but at the same time coming into conflict with the open structures of ordinary, non-scientific perception patterns in everyday life. On the basis of these distinctions, an analysis of the different perceptual patterns in medicine becomes possible. Such an analysis would be the task of a sub-field in medical philosophy that could be called medical aesthetics having as its goal an art of perception understood as a technique of adequately applying different perceptual patterns in medical practice.

This book of readings was designed for an introductory course in the theory of modern, Western law. The materials mine the depths of history, philosophy, politics, & ethics to bring to view a certain story of the present, past & future condition of modern Western legal theory, namely that "modern" legal theory is reaching its end with the new millennium.

Im Zentrum der 1874 erschienenen bewußtseinspsychologischen Abhandlungen Brentanos steht die Beschreibung und Analyse des Psychischen. Damit bahnte sich jene Abwendung von der sensualistischen Tradition der philosophischen Bewußtseinslehre an, die in der Phänomenologie Edmund Husserls vollendet wurde.

In solving judgment aggregation problems, groups often face constraints. Many decision problems can be modelled in terms the acceptance or rejection of certain propositions in a language, and constraints as propositions that the decisions should be consistent with. For example, court judgments in breach-of-contract cases should be consistent with the constraint that action and obligation are necessary and sufficient for liability; judgments on how to rank several options in an order of preference with the constraint of transitivity; and judgments on (...) budget items with budgetary constraints. Often more or less demanding constraints on decisions are imaginable. For instance, in preference ranking problems, the transitivity constraint is often contrasted with the weaker acyclicity constraint. In this paper, we make constraints explicit in judgment aggregation by relativizing the rationality conditions of consistency and deductive closure to a constraint set, whose variation yields more or less strong notions of rationality. We review several general results on judgment aggregation in light of such constraints. (shrink)

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

My dissertation combines philosophy of science and political philosophy. Drawing directly on the work of Alasdair MacIntyre and inspired by John Dewey, I develop two rival conceptions of scientific practice. I show that these rivals are closely linked to the two basic sides in the science and values debate -- the debate over the extent to which ethical and political values may legitimately influence scientific inquiry. Finally, I start to develop an account of justice that is sensitive to these legitimate (...) and illegitimate influences. (shrink)

The field of AI has undergone a series of transformations, each marking a new phase of development. The initial phase emphasized curation of symbolic models which excelled in capturing reasoning but were fragile and not scalable. The next phase was characterized by machine learning models—most recently large language models (LLMs)—which were more robust and easier to scale but struggled with reasoning. Now, we are witnessing a return to symbolic models as complementing machine learning. Successes of LLMs contrast with their inscrutability, (...) inaccuracy, and hallucinations, which underwrite concerns over the reliability and trustworthiness of these systems, motivating investigations into commonsense reasoning, AI explainability, and formal verification techniques. Moreover, proper assessments of hybrid machine learning/symbolic systems require novel strategies to facilitate comparisons of performance and guide future AI progress. The EDGeS AAAI 2023 Spring symposium brought together researchers focusing on novel assessments and benchmarks for evaluating hybrid and artificial general intelligence (AGI) systems. This symposium revealed what was already suspected: research concerning evaluation of machine learning/symbolic hybrids and AGI is, unfortunately, lacking. Even so, the discussion was fruitful.
