He also protected higher causes from responsibility by saying that evil may result from a combination of goods. Proclus objects: evil is real, and not the mere privation of form. Rather, it is a parasite feeding off good. Parasites have no proper cause, and higher beings are thus vindicated as being the causes only of the good off which evil feeds."--BOOK JACKET.

In "De malorum subsistentia" chs 30-7, Proclus criticizes the view that evil is to be identified with matter. His main target is Plotinus' account in Enn. I,8 [51]. Proclus denies that matter is the cause of evil in the soul, and that it is evil or a principle of evil. According to Proclus, matter is good, because it is produced by the One. Plotinus' doctrine of matter-evil is the result of a different conception of emanation, according to which matter does (...) not revert to its principle. Proclus claims that to posit a principle of evil either amounts to a coarse dualism, or makes the Good ultimately responsible for evil. Plotinus does not seem to be able to escape the latter consequence, if he is to remain committed to the Neoplatonic conception of causation. Plotinus equated matter with privation and said it is a kind of non-being that is the contrary of substance, thus violating fundamental Aristotelian tenets. Proclus reinstates Aristotelian orthodoxy, as does Simplicius in his "Commentary on the Categories." It is possible that lamblichus was the source of both Proclus and Simplicius, and that he was the originator of the parhypostasis theory and the inventor of the anti-Plotinian arguments. (shrink)

The treatise De intellectu attributed to Alexander of Aphrodisias can be divided into four sections. The first is an interpretation of the Aristotelian theory of intellect, and especially of the active intellect referred to in Aristotle, De anima 3.5, which differs from the interpretation in Alexander's own De anima, and whose relation to Alexander's De anima, attribution to Alexander, and date are all disputed. The second is an account of the intellect which is broadly similar to A though differing on (...) certain points. The third is an account of someone's response to the problem of how intellect can enter the human being ‘from outside’ if it is incorporeal and hence cannot move at all; in the fourth the writer who reported Cl criticizes that solution and gives his own alternative one.

Proposition 28 from Proclus'Elements of Theologyis consistently cited as saying that every producing causefirstbrings about effects that are like it andtheneffects that are unlike it. This is a theorem to which Proclus is indeed committed, but I argue that it is not what Proclus is claiming here. At this stage of his general argument, he merely argues that every cause produces things that are like it, without saying anything about other products than the immediate ones. The standard interpretation of proposition (...) 28 is therefore wrong. This becomes clear if one pays close attention to the argumentative structure of theElements of Theologyand to the proof given for proposition 28. (shrink)

In recent years, it has become clear that Proclus has an elaborate metaphysics, not only of the higher realm, but also of the natural world. This chapter first delimits its topic by explaining what physics or philosophy of nature is in Proclus’ view: the hypothetical study of all causes, but especially the transcendent causes of the natural world. After briefly addressing the question whether the world is eternal, the author moves on to presenting these causes in due order: first the (...) many demiurges and other productive causes, the different products of the different demiurgies, the plurality of paradigmatic causes, nature as the proximate cause of bodies, and finally the ontology of bodies, as hylomorphic entities, analysable into immanent forms and different levels of substrate or matter.

‘Authority’ is a term widely used in scholarly debate, including the history of philosophy. However, what is meant by this term is not always clear and the concept is not very well defined. One reason for this is certainly that the phenomenon itself is complex and the corresponding terms are used with a degree of latitude. This makes it difficult to adequately compare and connect the insights that various case studies have to offer. For historians of philosophy, it is thus (...) important to get a sufficient grasp of the concept of authority. This is even more urgent when one studies commentary traditions, in which secondary texts are written in virtue of the existence of texts clad with high authority. Our article combines historical textual research with insights from epistemology, thus providing a discussion of the concept of authority and its importance in textual traditions. We propose a descriptive model that can be used for examining epistemic authority in historical texts. An example from ancient Platonism serves to show both the complexity of the phenomenon and the clarifications that our approach may offer. (shrink)

Plutarch was a brilliant Platonist, an erudite historian, a gifted author of highly polished literary dialogues, a priest of Apollo at Delphi, and a devoted politician in his hometown Chaeronea. He felt confident in the most technical and specialized discussions, yet was not afraid of rhetorical generalizations. In his voluminous oeuvre, he appears as a sharp polemicist and a loving father, an ardent pupil but also a kind, inspiring teacher, a sober historian and a teller of wondrous tales. In view (...) of all these different personae, erudite versatility is without any doubt a major characteristic of Plutarch’s works. A Versatile Gentleman is dedicated to Luc Van der Stockt, professor emeritus of Greek language and literature at KU Leuven and a truly versatile gentleman. The volume aims to do justice to his and Plutarch’s versatility by discussing the Chaeronean from many different angles. As such, it sheds new light on the coherence of, and the tensions in, Plutarch’s thinking and writing. (shrink)

Die Wiederentdeckung der esoterischen Schriften des Aristoteles hat bei der Neugründung des dogmatischen Platonismus ab dem 1. Jh. v. Chr. eine entscheidende Rolle gespielt. Wie die aristotelischen Texte wurden auch die Dialoge Platons einer exegetisch-hermeneutischen Behandlung unterzogen, jeweils mit dem Ziel, die Philosophie des Schulgründers zu systematisieren. Bei der Entwicklung des platonischen Systems konnte der Aristotelismus ein technisches Vokabular sowie ein logisches und analytisches Instrumentarium liefern. Zudem ließen sich Ergänzungen finden für solche Bereiche, für die keine platonische Behandlung vorlag.

Iamblichus' theory of self-motion has to be pieced together from various texts and passing remarks. Ever since Aristotle's critique, Plato's concept of the self-motive soul was felt to be problematic. Taking his lead from Plotinus, Iamblichus counters Aristotle's criticism by claiming that true self-motion transcends the opposition between activity and passivity. He moreover argues that it does not involve motion that is spatially extended. Hence it is non-physical. Primary self-motion is the reversion of the soul to itself, by which the (...) soul constitutes itself, i.e. imparts life to itself. This motion is located at the level of essence or substance. The bestowal of life upon the body derives from this fundamental motion. As a result, animals are derivatively self-motive. Secondary self-motions are acts of thought in the broad sense. Contrary to the unmoved motion of intellect, the self-motion of the soul is not beyond time. This somehow fits Iamblichus' theory of the "changing self''. Iamblichus anticipates much of the later Platonic accounts of self-motion. (shrink)

Aristotle examines emotions in different works and from different perspectives. Ontologically, they are categorized as passing qualitative states of the soul. Yet they have both a bodily and a psychological aspect. While a proper definition of any emotion would need to render both aspects, in his Rhetoric Aristotle merely offers nominal definitions of emotions in general and of single emotions. He produces a sophisticated analysis of anger, which he defines as a response to a perceived slight. The angry person seeks (...) revenge, which consists in his or her regaining his or her superiority. In order to achieve this, it is necessary that the victim, that is the person responsible for the earlier slight, recognizes that she or he is made to suffer the revenge of the angry person. Anger is therefore accompanied by pain and pleasure: pain because of the perceived slight, pleasure because of the hope for revenge. Anger is morally neutral, but there are good and bad ways of being angry. (shrink)

From the 1st century BC onwards followers of Plato began to systematize Plato's thought. These attempts went in various directions and were subjected to all kinds of philosophical influences, especially Aristotelian, Stoic, and Pythagorean. The result was a broad variety of Platonisms without orthodoxy. That would only change with Plotinus. This volume, being the fruit of the collaboration among leading scholars in the field, addresses a number of aspects of this period of system building with substantial contributions on Antiochus and (...) Alcinous and their relation to Stoicism; on Pythagoreanising tendencies in Platonism; on Eudorus and the tradition of commentaries on Aristotle's Categories; on the creationism of the Jewish Platonist Philo of Alexandria; on Ammonius, the Egyptian teacher of Plutarch; on Plutarch's discussion of Socrates' guardian spirit. The contributions are in English, French, Italian and German. (shrink)

It can be tempting to think of affect as a matter of the present moment – a reaction, a feeling, an experience or engagement that unfolds right now. This paper will make the case that affect is better thought of as not only temporally extended but as saturated with temporality, especially with the past. In and through affectivity, concrete, ongoing history continues to weigh on present comportment. In order to spell this out, I sketch a Heidegger-inspired perspective. It revolves around (...) two claims. The first is that we should understand what Heidegger calls 'Befindlichkeit' (findingness) as radical situatedness. Affectivity is a matter of 'finding oneself' constellated – thrown – into the world in ways that outrun what an individual or collective might grasp and process. The second claim is that the temporal dimension, as a relatedness to the past, takes precedence in affect's situatedness. Key to affect is the way in which the past continues to hold sway over present comportment, collectively and individually. In order to articulate this perspective, it is important to overcome the idea that affect must be understood mainly in terms of feeling or experiential states of other kinds. Better suited to grasp the idea of findingness is the concept of 'disclosive posture', as proposed by Katherine Withy. I suggest that this notion should be put at the fore of a phenomenological approach to situated affectivity. (shrink)

Epigenetics is currently one of the fastest-growing fields in the sciences. Epigenetic information not only controls DNA expression but links genetic factors with the environmental experiences that influence the traits and characteristics of an individual. What we eat, where we work, and how we live affects not only the activity of our genes but that of our offspring as well. This discovery has imposed a revolutionary theoretical shift on modern biology, especially on evolutionary theory. It has helped to uncover the (...) developmental processes leading to cancer, obesity, schizophrenia, alcoholism, and aging, and to facilitate associated medial applications such as stem cell therapy and cloning. Above the Gene, Beyond Biology explores how biologists in this booming field investigate and explain living systems. Jan Baedke offers the first comprehensive philosophical discussion of epigenetic concepts, explanations, and methodologies so that we can better understand this "epigenetic turn" in the life sciences from a philosophical perspective.

The paper examines the interplays between logic and politics in the Polish School of Logic starting from 1914. The Polish School of Logic flourished between 1920 and 1939. Philosophically, it was influenced by Kazimierz Twardowski (1866–1938). For Twardowski logic is fundamental for every kind of human activity, professional and private and this means that every argument should be formulated and proceed by correct inferential rules. These rules involve semiotics, formal logic and methodology of science. The paper shows how this position (...) was shared by Twardowski’s students, including Jan Łukasiewicz, Stanisław Leśniewski, Kazimierz Ajdukiewicz and Tadeusz Kotrabiński, as well as by the next generation of logicians and philosophers and especially by Alfred Tarski. These authors considered logic, philosophy and science as completely neutral with respect to politics and ideology but they also considered logical skills as indispensable in political activities.

We introduce a cyclic proof system for the two-way alternation-free modal μ-calculus. The system manipulates one-sided Gentzen sequents and locally deals with the backwards modalities by allowing analytic applications of the cut rule. The global effect of backwards modalities on traces is handled by making the semantics relative to a specific strategy of the opponent in the evaluation game. This allows us to augment sequents by so-called trace atoms, describing traces that the proponent can construct against the opponent’s strategy. The (...) idea for trace atoms comes from Vardi’s reduction of alternating two-way automata to deterministic one-way automata. Using the multi-focus annotations introduced earlier by Marti and Venema, we turn this trace-based system into a path-based system. We prove that our system is sound for all sequents and complete for sequents not containing trace atoms. (shrink)

Higher-order logic, with its type-theoretic apparatus known as the simple theory of types (STT), has increasingly come to be employed in theorizing about properties, relations, and states of affairs—or ‘intensional entities’ for short. This paper argues against this employment of STT and offers an alternative: ordinal type theory (OTT). Very roughly, STT and OTT can be regarded as complementary simplifications of the ‘ramified theory of types’ outlined in the Introduction to Principia Mathematica (on a realist reading). While STT, understood as (...) a theory of intensional entities, retains the Fregean division of properties and relations into a multiplicity of categories according to their adicities and ‘input types’ and discards the division of intensional entities into different ‘orders’, OTT takes the opposite approach: it retains the hierarchy of orders (though with some modifications) and discards the categorisation of properties and relations according to their adicities and input types. In contrast to STT, this latter approach avoids intensional counterparts of the Epimenides and related paradoxes. Fundamental intensional entities lie at the base of the proposed hierarchy and are also given a prominent part to play in the individuation of non-fundamental intensional entities. (shrink)

By and large, the conditional connective in three-valued logic has two different functions. First, by means of a deduction theorem, it can express a specific relation of logical consequence in the logical language itself. Second, it can represent natural language structures such as "if/then'' or "implies''. This chapter surveys both approaches, shows why none of them will typically end up with a three-valued material conditional, and elaborates on connections to probabilistic reasoning.

International institutions such as UNESCO are deliberating on a new standard setting instrument for neurotechnologies. This will likely lead to the adoption of a soft law document which will be the first global document specifically tailored to neurotechnologies, setting the tone for further international or domestic regulations. While some stakeholders have been consulted, these developments have so far evaded the broader attention of the neuroscience, neurotech, and neuroethics communities. To initiate a broader debate, this target article puts to discussion twenty-five (...) considerations and desiderata for recognition by a future instrument. They are formulated at different levels of abstraction, from the big picture to technical details, seek to widen the perspective of preparatory reports and transcend the narrow debate about “neurorights” which overshadows many richer and more relevant aspects. These desiderata are not an exhaustive enumeration but a starting point for discussions about what deserves and what requires protection by an international instrument. (shrink)

Evidence-Based Medicine has little consideration for mechanisms and philosophers of science and medicine have recently made pleas to increase the place of mechanisms in the medical evidence hierarchy. However, in this debate the notions of mechanisms seem to be limited to 'mechanistic processes' and 'complex-systems mechanisms,' understood as 'componential causal systems'. I believe that this will not do full justice to how mechanisms are used in biological, psychological and social sciences and, consequently, in a more biopsychosocial approach to medicine. Here, (...) I propose, following (Kuorikoski, 2009), to pay more attention to 'abstract forms of interaction' mechanisms. The present work scrutinized review articles on depression and medically unexplained pain, which are considered to be of multifactorial pathogenesis, for their use of mechanisms. In review articles on these disorders there seemed to be a range of uses between more 'abstract forms of interaction' and 'componential causal system' mechanisms. I therefore propose to expand the notions of mechanisms considered in medicine to include that of more 'abstract forms of interaction' to better explain and manage biopsychosocial disorders.

Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the work, influences and legacy of the Nobel Prize physicist and philosopher of experiment Niels Bohr. While covering Bohr's groundbreaking contribution to quantum mechanics, this collection reveals the philosophers who influenced his work. Linking him to the pragmatist C.I. Lewis and the Danish philosopher Harald Høffding, it draws strong similarities between Bohr's philosophy and the Kantian way of thinking. Addressing the importance of Bohr's views of classical concepts, it discusses how (...) his interpretation of quantum mechanics now compares with a variety of issues that have arisen only since his lifetime, including decoherence and other non-collapse arguments. Balancing historical themes with contemporary ideas, Niels Bohrs and Philosophy of Physics reveals Bohr's on-going contribution to the philosophy of science and confirms his place in the history of philosophy.

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a noetic system and thereby (...) prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.

Kearns (2021) reconstructs Berkeley’s (1713) Master Argument as a formally valid argument against the Materialist Thesis, with the key premise the Distinct Conceivability Thesis, namely the thesis that truths about sensible objects having or lacking thinkable qualities are (distinctly) conceivable and as its conclusion that all sensible objects are conceived. It will be shown that Distinct Conceivability Thesis entails the Reduction Thesis, which states that de dicto propositional (ordinary or distinct) conceivability reduces to de re propositional (ordinary or distinct) conceivability. (...) While Kearns (2021) set out to avoid the confusion of a de re claim with a de dicto claim, which Prior (1955) accused Berkeley of, Kearns can be accused of making a similar conceptual confusion.
