The book provides a historical and systematic exposition of the semantic theory of truth formulated by Alfred Tarski in the 1930s. This theory became famous very soon and inspired logicians and philosophers. It has two different, but interconnected aspects: formal-logical and philosophical. The book deals with both, but it is intended mostly as a philosophical monograph. It explains Tarski’s motivation and presents discussions about his ideas as well as points out various applications of the semantic theory of truth to philosophical (...) problems. (shrink)

Empedocles’ B100 contains an analogy between a girl handling a clepsydra and respiration. This article argues that proposals to establish Love or Persephone as the girl’s respiratory equivalent are rendered unlikely by differences between their respective causal roles. Rather than her gender, this article emphasises the importance of the girl’s age: Empedocles required a playful child to handle the clepsydra. This child’s play results in the extra phase of submerging the clepsydra while the upper vent is open, which Empedocles needed (...) to form a parallel for the first static phase of respiration.

Studie pomocí segmentové analýzy pěti existujících zlomků Anaximandrovy zoogonie a antropogonie ukazuje, že Aetiův zlomek o zoogonii, dosud téměř všeobecně považovaný za nejspolehlivější, je složený ze segmentů spadajících do oblasti antropogonie – tj. že ve skutečnosti o Anaximandrově zoogonii nepřináší téměř žádné informace. Komplikovaný problém vztahu Anaximandrovy zoogonie a antropogonie je tím paradoxně vyřešen: o zoogonii bez Aetiova zlomku máme naprostý nedostatek zpráv.

Řecké sloveso metabiónai, objevující se v Aetiově zprávě o Anaximandrově zoogonii, bylo dosud považováno za ojedinělé a předpokládalo se, že může mít význam „změnit způsob života“, nebo „přežít“. Tato studie nachází dosud neznámé výskyty daného slovesa, které svědčí pro význam „změnit způsob života“, současně však upozorňuje na syntaktickou problematičnost tohoto významu v Aetiově textu.keywords: Anaximandros; zoogonie; metabiónai; řecký aorist; Aetios; Pseudo-Plútarchos; Placita.

It is difficult for us to effectively diagnose our current character state such that we can follow Aristotle's advice to aim for the opposite extreme. The law can provide us a general standard, and the household strives to fill in the particular gaps inevitable to laws that must be universal. Neither, however, can ensure a proper diagnosis. Careful attention to Aristotle's discussion of how the medical doctor generates health gives us a model we can apply to Aristotle's discussions of character (...) virtues and vices in Book IV of Nicomachean Ethics. The medical doctor must identify the form of health and its various lacks, must have a sufficiently varied set of images by which to properly grasp these in the varied context of human beings, must attend carefully to the patient's impeded form of health, and must trace this impediment back to some cause on the basis of which she can act to correct the problem. By applying this model, we can more profitably employ Aristotle's discussions of individual virtues in our responsible attempts to diagnose and heal the characters of those who belong to us.

Abstract: This article presents a strategy for introducing Presocratic thought to students in a manner that is both engaging and relevant. The first section addresses students' reactions to the claim that the Presocratics were the first philosophers. The second section considers how the fragmentary state of Presocratic thought does not hinder its comprehension. The third section proposes a classroom exercise for testing the scientific merits of each of the Presocratic theories. The final section proposes the use of a mock trial (...) as a means of applying the materialist approach introduced by the Presocratics to contemporary debates about free will and determinism.

Law clings to rules to stabilize a preferred normative reality. But rules never suffice. Character is the dark matter of law. Ethos anthropos daimon. “Character is fate.” This paradoxically reversible saying by the ancient Greek philosopher Heraclitus asserts that we are defined by the daimon – the god or messenger angel – with which we identify most. As Plato queried in the Phaedrus: which god do you follow, whose love claims you? In contemporary terms we might say, what character type, (...) what emotional ideal, what deep story do you hold most sacred? Out of the maelstrom that is the state of exception, choices must be made. What emotional field shall we occupy when we do politics and law? Bound by what sovereign values or ideals, embodied within what sort of character, emplotted in what sort of political or legal narrative? In synergy with culture, character plays out the emotional conflicts and aspirations of the time. Whether we witness this in the mostly silent resistance of unassimilable characters like Barnardine in Shakespeare’s Measure for Measure or in the silent prayer of nineteen-year-old Emma Gonzalez, in public protest against uncontrolled gun violence in American schools, we are all called upon, as citizens in public life, to occupy an emotional space that attains centrality within deep narratives that vie for political dominance. Reverse engineering liberal society, we might ask: what emotional and character ideals are optimal in order for a particular kind of political society to arise and be sustained? There is a reciprocal relationship between the sovereign authority of law and the character ideals that express a capacity and willingness to accept that authority. What will the configuration be? Addressing this question constitutes the ethical, esthetic, and epistemological calling of our time. (shrink)

The paper demonstrates that Parmenides’ monism is a logical consequence of his criteria for philosophy, in conjunction with the logical operators he uses, and their holistic connection. Parmenides, I argue, is the first philosopher to set out explicit criteria for philosophy, establishing as criterion not only consistency, but also what I call rational admissibility, the requirement when giving an account of something that the account be based on rational analysis and can withstand rational scrutiny. I give a detailed account of (...) the logical operators Parmenides uses in his argument and of the way in which his notion of being is tailored to fit both them and his criteria for philoso-phy.

Some hold that the lesson of Russell’s paradox and its relatives is that mathematical reality does not form a ‘definite totality’ but rather is ‘indefinitely extensible’. There can always be more sets than there ever are. I argue that certain contact puzzles are analogous to Russell’s paradox this way: they similarly motivate a vision of physical reality as iteratively generated. In this picture, the divisions of the continuum into smaller parts are ‘potential’ rather than ‘actual’. Besides the intrinsic interest of (...) this metaphysical picture, it has important consequences for the debate over absolute generality. It is often thought that ‘indefinite extensibility’ arguments at best make trouble for mathematical platonists; but the contact arguments show that nominalists face the same kind of difficulty, if they recognize even the metaphysical possibility of the picture I sketch.

This essay explores a curious point of intersection in the historical pairing of becoming and negation, between two thinkers and two traditions: the Sophist Protagoras of fifth-century BCE Greece and the second-century CE South Asian Buddhist thinker Nāgārjuna. I offer a speculative account of how becoming and negation are linked in Protagoras—speculative because only so much can be deduced from the extant fragments and testimony. I compare that account to the more coherent picture offered by Nāgārjuna—more coherent because a complete (...) account of the logic that links becoming and negation is carefully preserved in the works attributed to Nāgārjuna. While no specific conclusions regarding the bridge that linked India and Greece may be reached, the similarities between these thinkers and the greater coherence of the Buddhist tradition nevertheless offer hypothetical possibilities for reconstructing the larger architecture of the world of sophistic thought that is now lost to us.

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early in his (...) life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the Ph.D. at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology. (shrink)

_ Source: _Volume 63, Issue 1, pp 1 - 24 This article examines Diogenes of Apollonia’s doctrines of intellection and soul in relation to his material principle, air. It argues that for Diogenes both intellection and soul are not, as commonly thought, some sort of air, even though both intellection and soul are to be understood in terms of air and the system of τρόποι of air that he has set up. These new interpretations of intellection and soul yield insight (...) into Diogenes’ claims about the ordering activity of air as intellection and a renewed appreciation for his material monism.

Something Aristotle calls ‘right logos’ plays a crucial role in his theory of virtue. But the meaning of ‘logos’ in this context is notoriously contested. I argue against the standard translation ‘reason’, and—drawing on parallels with Plato’s work, especially the Laws—in favor of its being used to denote what transforms an inferior epistemic state into a superior one: an explanatory account. Thus Aristotelian phronēsis, like his and Plato’s technē and epistēmē, is a matter of grasping explanatory accounts: in this case, (...) accounts that identify the right action and say why it is right. Arguably, Aristotelian rationality is a matter of being able to grasp accounts in general. (shrink)

This article examines the well from which learning, teaching, and research originate. It investigates how to perform these three aspects of academic practice well and to do it in a playful manner. Instead of repeating existing knowledge and scientific methods punctiliously, the playful academic experiences and presents knowledge in new or alternative ways. Playfulness more often results in discoveries and inventions that are otherwise unthinkable. -/- Through an analysis of a selection of Plato’s myths, allegories, and imagery, the article demonstrates (...) how very complicated subject matters can be illustrated in a playful, synecdochic form, hereby making the unfathomable easier to approach and understand. -/- Examining Plato’s concept of ‘agalma’ – the beautiful ornament of wisdom – the article discusses how we can see academia as a jewellery box, or as a plaything. Agalma allows us to see learning, teaching, and research as an adventurous journey or as a playful labyrinth leading into all dimensions of being. (shrink)

This contribution considers the potential of critical realism to illuminate the nature of crises, crisis management, and crisis lessons. After reviewing key aspects of critical realism in general, the analysis notes the challenge of developing critical realism in particular by identifying appropriate entry-points and standpoints for the analysis of specific explananda. It then provides a general critical realist account of the nature of crises in the social world and of learning in, about, and from crisis. A key concept here is (...) symptomatology — the exploration of the contingently necessary relation between actual symptoms and underlying causal mechanisms. This is related in turn to the crucial distinction between scientifically adequate explanations of crisis and conjuncturally ‘correct’ readings of the potential for transformative action in the face of crisis. This has important bearings on the emancipatory contribution of critical realism in the context of a continuing critique of ideology and domination. The article then provides particular critical realist accounts of the abstract possibility of crisis in the capitalist mode of production and its concrete actualization in the complex, overdetermined cases of the North Atlantic Financial Crisis and the Eurozone Crisis. It ends with some general remarks on the potential of crisis as an entry-point into the analysis of the contradictory nature of social structures. (shrink)

In paragraphs 5 and 86 of the De sensibus Theophrastus gives a brief report of Plato’s views on the sense of vision and its object, i. e. colour, based on the Timaeus. Interestingly enough, he presents the Platonic doctrine as a third alternative to the extramission and intromission theories put forward by other ancient philosophers. In this article I examine whether or not Theophrastus’ account is impartial. I argue that at least some of his distortive departures from the Platonic dialogue (...) are due to his Aristotelian inheritance, even though they do not always represent Aristotle’s expressed views.

Anaximenes is usually considered to be a material monist recognizing transparent atmospheric air as a principle (ἀρχή). In the cosmogonic explanation of the origin of the earth and the heavenly bodies, the Greek term ἀήρ turns out to mean rather ‘opaque damp mist’. However, Not only does it accord with archaic usage, but also with how it was used in his mentor, Anaximander. Yet, in cosmology ἀήρ means ‘air’ serving as stuff on which the earth and the heavenly bodies float. (...) Hence, in keeping with contemporary usage, Anaximenes recognised two kinds of ἀήρ, distinguishing them functionally. Whereas mist is conceived of as a generating substance, air functions only as carrying stuff. (shrink)

In 1927, the Scottish philosopher John Anderson arrived in Australia to take up the chair of Philosophy at the University of Sydney. By the late 1930s, the ‘macrostructure’ of his realist system was in place. It includes a theory of process and a substantial metaphysics, one that opposes positivism, linguistic philosophy and all forms of idealism. However, beyond Australia it remains largely unknown, despite its bearing on a number of current issues in psychology and the social sciences generally. This article (...) outlines Anderson’s transition from Hegelian idealism to realism, describes aspects of his ontology and epistemology, compares some of Anderson’s ideas with Dewey’s pragmatism and explains their relevance to present-day psychology.

The Anaximander fragment, in the readings of both Heidegger and Derrida, speaks of that which exceeds positive law. In this article, the author provides a detailed reading of Heidegger’s Der Spruch des Anaximander, showing how Heidegger relates this fragment to his thinking of Being, the latter having been ‘forgotten’ by metaphysics. Heidegger’s reading at the same time involves a contemplation of technology and of the ontological relation of beings to each other. Derrida’s reading of Heidegger’s Der Spruch highlights specifically those (...) parts of Heidegger’s text where that which precedes Being’s gathering, Being’s disjoining or dissemination, is pointed to. This disjoining, Derrida contends, speaks of the gift of a day more ancient than memory itself and ties in closely with certain aspects of the thinking of Marx. Derrida’s focus on that which precedes Being is in turn related to his contemplation of the law or condition of possibility of technology and also of that which makes possible a relation to the other as other. This condition of possibility, or the gift of Being, which Heidegger’s text also speaks of, involves a ‘higher law’ which can serve as a ‘measure’ for the evaluation, interpretation and transformation of positive law.

The aim of this paper is to examine the implications of Plato’s use of the term stoicheion, since his awareness of stoicheion’s polysemy reveals his view of the origin, the complexity and, at the same time, the order of reality. Moreover, his use of stoicheion allowed him both to inherit and to detach himself from his predecessors. I begin by presenting the history of the notion of stoicheion; then, since one of the meanings of stoicheion is ‘letter of the alphabet’, (...) I focus on the Cratylus, which contains the first of several passages where Plato employs the alphabet as a paradigm for the structure of a complex system. Finally, I turn to the Theaetetus, where Plato, for the first time, uses stoicheion in the sense of ‘element’ and where, through the relation letters/syllables, Plato clarifies that enumeration and juxtaposition are not sufficient to attain the real knowledge. I will argue that only thanks to these steps can we understand the occurrences of stoicheion in the Timaeus, where Plato first states that air, earth, fire and water are not stoicheia tou pantos, and then reveals that, instead, the basic triangles are ‘the elements of the universe’.

Near the beginning of De Gen. et Cor. II.1, Aristotle claims that the generation and corruption of all naturally constituted substances are “not without the perceptible bodies”. It is not clear what he intends by this. In this paper I offer a new interpretation of this assertion. I argue that the assumption behind the usual reading, namely, that these “perceptible bodies” ought to be distinguished from the naturally constituted substances, is flawed, and that the assertion is best understood as a (...) claim that Aristotle has established in the second half of the first book of the De Gen. et Cor.

This paper gives continuity to the criticism, undertaken in two papers previously published in this journal, of transpersonal systems that fail to discriminate between nirvanic, samsaric, and neithernirvanic-nor-samsaric transpersonal states, and which present the absolute sanity of Awakening as a dualistic, conceptually-tainted condition. It also gives continuity to the denunciation of the false disjunction between ontogenically ascending and descending paths, while showing the truly significant disjunction to be between existentially ascending and metaexistentially descending paths. However, whereas in the preceding paper (...) the focus was on Wilber’s so-called integral system, in this paper the focus of the main body is on the systems of Washburn and Grof. It features an appendix discussing psychedelics and the use of the term entheogens in their regard, and another appendix showing Wilber’s system to give continuity to the Orphic dualism of Pythagoreans, Eleatics, and Plato, and the covert Orphic dualism of Neo-Platonics.

This paper is devoted to the analysis of Plotinus’ citation of the Heraclitean saying B113 DK in the second treatise On the Presence of Being (VI 5 [23]). I shall argue that the use which the author of the Enneads makes of this fragment has been hitherto misunderstood by scholars and that, for this reason, the significance of the passage and its role within Plotinus’ argument have been missed. Close attention will be paid to the tool through which Plotinus conveys (...) his own reading of Heraclitus’ tenet, i.e. etymology, and to the passages in which he both lays down and puts into practice the programmatic guidelines for his interpretation of the Presocratic. In addition, I shall interpret Plotinus’ recourse to a wordplay which is, in character, quite Heraclitean as a proof of the importance of his philosophical engagement with the Obscure. (shrink)

Dialectic has been a fundamental part of philosophy since the time of Anaximander, which is a method of argumentation and reasoning. Anaximander’s thought is deeply rooted in the Milesian school of philosophy, where philosophers used dialectic to explore and explain life and the world. This philosophical method focuses on the idea of opposites and how they interact and influence each other to create a more complete understanding of the ideas. The presence of dialectic in Anaximander’s philosophy is evident in his (...) Apeiron which allowed him to challenge and question existing ideas. This article will explore the role of dialectic in Anaximander’s philosophy, including an analysis of his Apeiron and how it shaped his philosophical ideas. To reach its conclusion, this article applies an analytical approach and depends on secondary sources of data. By studying Anaximander’s philosophy through a dialectical lens, we can gain a deeper appreciation for his contributions to Western philosophy as well as to the realm of knowledge. (shrink)

Anaxagoras of Clazomenae (a major Greek city of Ionian Asia Minor), a Greek philosopher of the 5th century B.C.E. (born ca. 500–480), was the first of the Presocratic philosophers to live in Athens. He propounded a physical theory of “everything-in-everything,” and claimed that nous (intellect or mind) was the motive cause of the cosmos. He was the first to give a correct explanation of eclipses, and was both famous and notorious for his scientific theories, including the claims that the sun (...) is a mass of red-hot metal, that the moon is earthy, and that the stars are fiery stones. Anaxagoras maintained that the original state of the cosmos was a mixture of all its ingredients (the basic realities of his system). The ingredients are thoroughly mixed, so that no individual ingredient as such is evident, but the mixture is not entirely uniform or homogeneous. (shrink)

A pergunta, “Tudo é número?” no título do famoso artigo de 1989 de Zhmud, deixa aberto um desafio para o extremamente importante testemunho aristotélico de que “tudo é número” era a definição fundamental da filosofia pitagórica. Tal desafio não é nada simples, especialmente quando se considera que, até então, as histórias tanto da filosofia quanto da matemática antiga parecem não ter dúvidas de que esta afirmação é correta. Este artigo pretende submeter à avaliação crítica a alegação de Aristóteles de que (...) os pitagóricos acreditavam que “tudo é número”. Nossa análise dos muitos modos nos quais Aristóteles enuncia a tese de que “tudo é número” revelará, para além de variações meramente semânticas, uma contradição teórica fundamental que o próprio Aristóteles parece incapaz de resolver. De fato, três versões diferentes da doutrina estão presentes na doxografia aristotélica: uma identificação dos números com objetos sensíveis; uma identificação dos princípios dos números com os princípios das coisas que existem; uma imitação dos objetos pelos números. Enquanto as versões e parecem identificar, em termos que lembram Platão, os números com a causa material da realidade, a versão, a saber, números como causas formais da realidade, é uma reconstrução aristotélica da teoria pitagórica. Aristóteles teria sido levado a tal reconstrução pela dificuldade que encontrou para aceitar a noção pitagórica material de número, e por considerá-la, para seu gosto, fortemente marcada pela recepção da mesma teoria no ambiente da Academia.

ABSTRACT (ENG) One of the concerns of Greek philosophy centred on the question of how a manifold and ordered universe arose out of the primitive state of things. From the mythical accounts dating around the seventh century B.C. to the cosmologies of the Classical period in Ancient Greece, many theories have been proposed in order to answer to this question. How these theories differ in positing a “something” that pre-existed the ordered cosmos has been widely discussed. However, scholars have rarely (...) made explicit how they differ in style of thought. In the span of four centuries the first deductive arguments of the Eleatic philosophers culminated in the emergence of logical proof and a form of explanation of natural phenomena, which consisted of searching for the simplest and fewest premises and deducting implications. In this paper it will be discussed how, at distinct stages of its development, the deductive thinking informed the solutions proposed to solve the chaos-order problem, that of how an ordered universe has been possible. -/- ABSTRACT (ITA) Una delle più importanti questioni della filosofia greca è stata quella di comprendere come sia stato possibile un universo ordinato a partire da uno stato primordiale. Dalle teogonie del VII secolo a.C. fino alle cosmologie dei filosofi dell’età classica, sono state proposte diverse teorie per dare risposta a questa domanda. Come esse differiscano nel postulare l’esistenza di un “qualcosa” di primordiale che preesisteva all’ordine del cosmo è stato molto discusso. Pochi studiosi, però, le hanno esaminate sullo sfondo della lenta evoluzione del pensiero deduttivo, culminata nella dimostrazione in geometria e in una forma di spiegazione dei fenomeni che consisteva nel cercare semplici premesse e inferire conclusioni. In questo articolo si mostrerà come il lento affermarsi della spiegazione razionale prima, dell’argomento deduttivo e della dimostrazione in geometria poi, abbiano dato forma alle diverse risposte al problema caos-ordine, e in particolare alla domanda su come sia sorto un universo ordinato.

Tales de Mileto (VII–VI a.C.), además de ser uno de los siete Sabios, es considerado el primer filósofo precisamente por haber sido el primero en intentar dar razón de la estructura y formación del universo. El punto nuclear de la tesis de Tales afirmaba que el agua es el principio o materia originaria de la que han surgido todas las realidades que componen el variopinto y complejo tejido cósmico. A esta tesis, que hoy bien pudiera parecer extravagante, le cabe el (...) mérito y el privilegio de haber sido el motor que puso en movimiento un conjunto de inquietudes, de recursos y de métodos, de base racional, encaminados a dar respuesta a cuestiones que los seres humanos venían planteándose desde la misma noche de los tiempos. En qué medida y en qué sentido Tales de Mileto es deudor de creencias, instrumentos y saberes de su entorno (las ciudades griegas de las costas turcas del Egeo), incluidos los procedentes del este (Mesopotamia) y del Sur (Egipto), en qué medida fue Tales un innovador radical, son cuestiones que serán abordadas en este artículo.
