This review tries to show that even if Plato ties the soul in the later dialogues more to the body, he still adheres in the Timaeus to the separation of the soul from the body as far as it is possible for humans, and in the Laws to the soul as a separated entity whose union with the body is in no way better than separation.

In the last decade alone, a growing body of preliminary evidence suggests that classic psychedelics (CPs) can rapidly and durably ameliorate symptoms and cognitive deficits associated with depression. However, the mechanisms by which CPs work in the brain are not well understood. Rodent translational research, in which experimental findings from rodents are translated to humans, is fundamental in achieving this goal. This chapter focuses on a representative subset of human and rodent studies investigating CPs for depression, including the various (...) lines of research that have been initiated to understand how they work. Our aim is to show that in addition to epistemic challenges that scientists face in translating findings from rodents to humans, there is also mismatch between experimental approaches used to investigate CPs in humans and rodents. We thus show current experimental practices are not conducive to mechanistic discovery. We end with a set of positive proposals to expedite the drive to translate CPs into effective treatments for depression. -/- Keywords: classic psychedelics, psychiatry, clinical trials, collaboration, extrapolation, major depressive disorder, open science, philosophy of science, rodent models, scientific practice, translation, validity .

This review establishes Rukmani, Indian philosophy and Yoga as cornerstones of Indian Studies.

The impact of Persian literature on world culture and literature is undeniable. Persian poets such as Firdowsi, Sa’di, Hafiz, Rumi and Khayyam who deal with universal themes beyond a particular place and time are among the most widely-known literary figures of the world; their works are translated into different languages. Despite the fact that there are different translations of Persian literature in English, it is still not clear whether Persian literature has gained its appropriate place in the world. We study (...) the reception of Persian literature in general and classical Persian poetry in particular in Britain and The United States to see whether it is rightly introduced to these countries or not. A close study of the reception of Persian poetry in Anglophone world in general and in Britain and The United States in particular reveals that while Persian literature is introduced and taught in these countries, it is still far from being truly known there. Those who have been familiar with Persian literature have mainly known it through translations by western scholars, and this has led to problems and misconceptions. As Edward Said argues in Orientalism, the orient is never truly depicted by the west. The best way would be to have Persian scholars of English literature translate Persian works into English.

"I tend to agree with more dialectical positions such as Noxon's who, even being a critic of the approach of the two concepts, writes the following: Hume explained certain mental phenomena, notably belief, as effects of the association. And, going further, I say that belief is a feeling or sensation aroused by two factors: habit and the association of ideas, but it does not arise either from one or from other singly, each one is a part of a process that (...) involves both. Therefore habit is an underlying principle which acts upon reasonable beings during their observation of constant conjunctions, in such a way that imagination can associate ideas only through this principle acting in the mind. However, as I have already stated in another text, such an association realised by the imagination will catch up to its certainty status just with the emergence of a feeling which imputes necessity to what is instead merely contingent" (Sample taken up from the text).

There was a time when 'logic' just meant classical logic. The climate is slowly changing and non-classical logic cannot be dismissed off-hand. However, a metatheory used to study the properties of non-classical logic is often classical. In this paper, we will argue that this practice of relying on classical metatheories is problematic. In particular, we will show that it is a bad practice because the metatheory that is used to study a non-classical logic often (...) rules out the very logic it is designed to study. (shrink)

Two seemingly contradictory tendencies have accompanied the development of the natural sciences in the past 150 years. On the one hand, the natural sciences have been instrumental in effecting a thoroughgoing transformation of social structures and have made a permanent impact on the conceptual world of human beings. This historical period has, on the other hand, also brought to light the merely hypothetical validity of scientific knowledge. As late as the middle of the 19th century the truth-pathos in the natural (...) sciences was still unbroken. Yet in the succeeding years these claims to certain knowledge underwent a fundamental crisis. For scientists today, of course, the fact that their knowledge can possess only relative validity is a matter of self-evidence. The present analysis investigates the early phase of this fundamental change in the concept of science through an examination of Hermann von Helmholtz's conception of science and his mechanistic interpretation of nature. Helmholtz (1821-1894) was one of the most important natural scientists in Germany. The development of this thoughts offers an impressive but, until now, relatively little considered report from the field of the experimental sciences chronicling the erosion of certainty. (shrink)

Enric F. Gel has recently argued that classical theism enjoys a significant advantage over Graham Oppy's naturalism. According to Gel, classical theism – unlike Oppy's naturalism – satisfactorily answers two questions: first, how many first causes are there, and second, why is it that number rather than another? In this article, I reply to Gel's argument for classical theism's advantage over Oppy's naturalism. I also draw out wider implications of my investigation for the gap problem and Christian (...) doctrine along the way. (shrink)

Surely God, as a perfectly rational being, created the universe for some _reason_. But is God’s creating the universe for a reason compatible with divine impassibility? That is the question I investigate in this article. The _prima facie_ tension between impassibility and God’s creating for a reason arises from impassibility’s commitment to God being uninfluenced by anything _ad extra_. If God is uninfluenced in this way, asks the detractor, how could he be moved to create anything at all? This _prima (...) facie_ tension has recently been formalized and dubbed the ‘Problem of Arbitrary Creation’. In this article, I defend a new extension of this problem. I begin by characterizing classical theism, divine simplicity, and divine impassibility. I then spell out the Problem of Arbitrary Creation as developed by R. T. Mullins. I next raise a worry for Mullins’ version of the argument. Finally, I extend the argument and show how my extension avoids the aforementioned worry. (shrink)

Nietzsche sometimes praises the drive to order—to simplify, organize, and draw clear boundaries—as expressive of a vital "classical" style, or an Apollonian artistic drive to calmly contemplate forms displaying "epic definiteness and clarity." But he also sometimes harshly criticizes order, as in the pathological dialectics or "logical schematism" that he associates paradigmatically with Socrates. I challenge a tradition that interprets Socratism as an especially one-sided expression of, or restricted form of attention to, the Apollonian: they are more radically disparate. (...) Beyond strengthening the case for this basic point, I develop a distinctive account of what, exactly, distinguishes the Apollonian-classical and Socratic forms of order. To this end, I advance interrelated interpretations of Apollonian-classical simplicity and the "cold" calm that it elicits, by contrast to superficially similar Socratic phenomena. This illuminates Nietzsche's broader ambivalence toward science, in part by clarifying the nature and value of an idealized Apollonian science. (shrink)

Isaac Newton, in popular imagination the Ur-scientist, was an outstanding humanist scholar. His researches on, among others, ancient philosophy, are thorough and appear to be connected to and fit within his larger philosophical and theological agenda. It is therefore relevant to take a closer look at Newton’s intellectual choices, at how and why precisely he would occupy himself with specific text-sources, and how this interest fits into the larger picture of his scientific and intellectual endeavours. In what follows, we shall (...) follow Newton into his study and look over his shoulder while reading compendia and original source-texts in his personal library at Cambridge, meticulously investigating and comparing fragments and commentaries, and carefully keeping track in private notes of how they support his own developing ideas. Indeed, Newton was convinced that precursors to his own insights and discoveries were present already in Antiquity, even before the Greeks, in ancient Egypt, and he puts a lot of time and effort into making the point, especially, and not incidentially, in the period between the first and the second edition of the Principia. A clear understanding of his reading of the classic sources therefore matters to our understanding of its content and gestation process. In what follows we will confine ourselves to the classical legacy, and investigate Newton’s intellectual intercourse with it. (shrink)

Following the pioneering studies of the receptive field (RF), the concept gained further significance for visual perception by the discovery of input effects from beyond the classical RF. These studies demonstrated that neuronal responses could be modulated by stimuli outside their RFs, consistent with the perception of induced brightness, color, orientation, and motion. Lesion scotomata are similarly modulated perceptually from the surround by RFs that have migrated from the interior to the outer edge of the scotoma and (...) in this way provide filling-in of the void. Large RFs are advantageous to this task. In higher visual areas, such as the middle temporal and inferotemporal lobe, RFs increase in size and lose most of their retinotopic organization while encoding increasingly complex features. Whereas lowerlevel RFs mediate perceptual filling-in, contour integration, and figure–ground segregation, RFs at higher levels serve the perception of grouping by common fate, biological motion, and other biologically relevant stimuli, such as faces. Studies in alert monkeys while freely viewing natural scenes showed that classical and nonclassical RFs cooperate in forming representations of the visual world. Today, our understanding of the mechanisms underlying the RF is undergoing a quantum leap. What had started out as a hierarchical feedforward concept for simple stimuli, such as spots, lines, and bars, now refers to mechanisms involving ascending, descending, and lateral signal flow. By extension of the bottom-up paradigm, RFs are nowadays understood as adaptive processors, enabling the predictive coding of complex scenes. Top-down effects guiding attention and tuned to task-relevant information complement the bottom-up analysis. (shrink)

Wigner's quantum-mechanical classification of particle-types in terms of irreducible representations of the Poincaré group has a classical analogue, which we extend in this paper. We study the compactness properties of the resulting phase spaces at fixed energy, and show that in order for a classical massless particle to be physically sensible, its phase space must feature a classical-particle counterpart of electromagnetic gauge invariance. By examining the connection between massless and massive particles in the massless limit, we also (...) derive a classical-particle version of the Higgs mechanism. (shrink)

In this paper I present the common structure of quantum theories with a primitive ontology, and discuss in what sense the classical world emerges from quantum theories as understood in this framework. In addition, I argue that the primitive ontology approach is better at answering this question than the rival wave function ontology approach or any other approach in which the classical world is nonreductively ‘emergent:’ even if the classical limit within this framework needs to be fully (...) developed, the difficulties are technical rather than conceptual, while this is not true for the alternatives.

In this paper, we review a general technique for converting the standard Lagrangian description of a classical system into a formulation that puts time on an equal footing with the system's degrees of freedom. We show how the resulting framework anticipates key features of special relativity, including the signature of the Minkowski metric tensor and the special role played by theories that are invariant under a generalized notion of Lorentz transformations. We then use this technique to revisit a classification (...) of classical particle-types that mirrors Wigner's classification of quantum particle-types in terms of irreducible representations of the Poincaré group, including the cases of massive particles, massless particles, and tachyons. Along the way, we see gauge invariance naturally emerge in the context of classical massless particles with nonzero spin, as well as study the massless limit of a massive particle and derive a classical-particle version of the Higgs mechanism.

This work contributes to the theory of judgement aggregation by discussing a number of significant non-classical logics. After adapting the standard framework of judgement aggregation to cope with non-classical logics, we discuss in particular results for the case of Intuitionistic Logic, the Lambek calculus, Linear Logic and Relevant Logics. The motivation for studying judgement aggregation in non-classical logics is that they offer a number of modelling choices to represent agents’ reasoning in aggregation problems. By studying judgement aggregation (...) in logics that are weaker than classical logic, we investigate whether some well-known impossibility results, that were tailored for classical logic, still apply to those weak systems.

Recent years have seen the beginning of a radical reassessment of the philosophical literature of ancient and classical India. The analytical techniques of contemporary philosophy are being deployed towards a fresh and original interpretation of the texts. This rational rather than mystical approach towards Indian philosophical theories has resulted in a need to work which explains afresh its central methods, courses and devices. It is with this spirit of thought and background that I want to publish a book to (...) discuss the relevance and need of classical Indian thoughts. The present collection is a significant step on this part because it recognizes the potentials of classical Indian tradition and its vast wisdom to contribute in all realms of life. Here we have collected 20 papers both in English and Hindi language written on Indian epistemology, metaphysics, logic, ethics and social philosophy. But in this volume only 9 papers were published and remaining papers will be published in second edition along with the same papers. To study the nature of philosophy in India and its implementation in all spheres of human life is one of the most important objectives of our Centre. In this regard we have published two online books entitled Philosophy, Education and Indian Value System and Positive Philosophy for Contemporary Indian Society, respectively. (shrink)

Although the works of the authors of the Golden Age of Latin Literature play an important formative role for Early Modern philosophers, their influence in Early Modern thought is, nowadays, rarely studied. Trying to bring this topic to light once again and following the seminal works of Kajanto (1979), Proietti (1985) and Akkerman (1985), I will target Spinoza’s Latin sources in order to analyze their place in his philosophy. On those grounds, I will offer an overview of the problems of (...) the reception of classical literature in Early Modernity and then dwell on the particular case of Ovid and Spinoza. The present paper will argue that although Spinoza’s references to Ovid fill a rhetorical purpose as suggested by the existing literature, these mentions have a prior philosophical motivation. That is, the references in the Ethics are not merely illustrative; instead, they indicate that Spinoza acknowledges Ovid’s beliefs about human experiences and deliberately elaborates on Ovid’s view to construct and defend his own theses. To this end, the paper will analyze some citations mapped by Proietti (1985) and add a new one in an attempt to enlarge the list of places and topics that merit further investigation. To conclude, I will point out how the references to Ovid are part of Spinoza’s own defense of the powers of imagination. (shrink)

In the ancient Greek world, the concept of 'miasma,' which becomes permanent and has the potential to grow over time due to evil acts such as murder committed in the city, is a concept frequently referred to in many classical tragedies. To the extent that miasma has a bad connotation due to its nature and is a situation that occurs due to evil actions, it can be considered together with the philosophical problem of evil. In this study, we aim (...) to examine the concept of miasma by focusing on the characters in La Jauría, one of the most prominent films of recent South American cinema, rather than a purely conceptual analysis of the concept. Filmed in the jungles of Colombia and directed by Colombian director Andrés Ramírez Pulido, the 2022 film La Jauría is a psychological drama that focuses on the lives of young people involved in crime. The tragic story of Eliu, the protagonist of the film, which takes place mainly in a prison specially designed to rehabilitate inmates, seems to us to be a very suitable focal point for examining the concepts of miasma, catharsis, and ecstasy, which are frequently referred to in ancient Greek tragedy. To do so, we will first address the various contexts in which miasma has been used historically, considering the flow of events in the movie La Jauría. Then, we will look at the relationship of the concept of miasma with the problem of evil. Finally, we will discuss the possibilities of the concept of purification, which is seen as a kind of antidote to miasma. (shrink)

In this thesis, we will study the embedding of classical first-order logic in first-order S4, which is based on the translation originally introduced in Fitting (1970). The initial main part is dedicated to a detailed model-theoretic proof of the soundness of the embedding. This will follow the proof sketch in Fitting (1970). We will then outline a proof procedure for a proof-theoretic replication of the soundness result. Afterwards, a potential proof of faithfulness of the embedding, read in terms of (...) soundness and completeness, will be discussed. We will particularly highlight the many difficulties coming with it. In the final section, we will relate this discussion to the debate on notational variance in French (2019). We will do this by showing how a weaker version of French's notion of ‘expressive equivalence’ conforms to the model-theoretic soundness result. We will then conclude that the soundness result without completeness might contain rather little overall insight by relating it to the extensibility of classical logic to S4. (shrink)

We argue that there is a conflict among classical theism's commitments to divine simplicity, divine creative freedom, and omniscience. We start by defining key terms for the debate related to classical theism. Then we articulate a new argument, the Aloneness Argument, aiming to establish a conflict among these attributes. In broad outline, the argument proceeds as follows. Under classical theism, it's possible that God exists without anything apart from Him. Any knowledge God has in such a world (...) would be wholly intrinsic. But there are contingent truths in every world, including the world in which God exists alone. So, it's possible that God contingently has wholly intrinsic knowledge. But whatever is contingent and wholly intrinsic is an accident. So, God possibly has an accident. This is incompatible with classical theism. Finally, we consider and rebut several objections. (shrink)

Ancient philosophy has, for the most part, focused particularly around the history and philosophies of the Pre-Socratics, Socrates, Plato and Aristotle, with broader representations of some other non-Greek philosophical traditions such as the Chinese, Indian and Iranian philosophies. However, a distinctive Eurocentric bias towards ancient Egypt, to which many ancient Greek philosophers looked to as the cradle of wisdom and philosophy, has blatantly disregarded the poignant place of African philosophy in the pedagogy of ancient philosophy. Thus, this paper argues for (...) re-centering ancient Egyptian philosophy, and by extension, African philosophy in the study of ancient philosophy. The paper, firstly, traces the historical originality and rich elements of philosophy that ancient Egypt possesses, and then, identifies how these served as the theoretical springboard for the emergence of Greek philosophy. Any comprehensive study of ancient philosophy should not deliberately exclude this important aspect of development in philosophical thought. The paper, therefore, concludes with recommendations on repositioning African philosophy within the pedagogical context of ancient philosophy. (shrink)

The five classical elements of creation are also known as Panch Tattva or the basic elements of life. Within these, and through these, life has prevailed and evolved. Although various religious philosophies differ in many details, they emphasize the fundamental unity of the universe through recognizing these elements as the basis of creation. Thus, Panch Tattva's knowledge helps us transcend the notion of an isolated individual self and identify ourselves with the ultimate reality.

In the study of education, as in many more travelled regions of Classical scholarship, democratic Athens is something of a special case. The cautions formulation is appropriate: in the case of education, surprisingly few studies have sought to establish quite how special Athens was, and those which have, have often raised more questions than they answered. The subject itself is partly to blame. The history of education invites comparison with the present day, while those planning the future of (...) education rarely fail to invoke the past. The place of Classical Athens in European culture has ensured a place for Athenian education in almost every debate from the relation between education and democracy to the value of educationversustraining, and as the original champion of causes as varied as mass education, co-education, and the national curriculum. Desirable as it is to be in demand, such treatment is not calculated to produce the most circumspect account of the subject. The study of education is further hampered by the fact that our knowledge of Athenian culture is so vibrant and diverse in some ways and so partial in others. Plato and Aristophanes present a vivid fictional picture of education in the late fifth century. If we add a few passages from Xenophon and Aristotle, a large number of vases depicting men, women, and children reading, playing the lyre, and doing athletics, and one or two archaeological finds of an educational appearance, it is tempting to take the result as a clear portrait of a society at school.

Our objectives in this paper are, first, to identify several puzzling aspects of the “Trilemma Argument” of Section 6 against the Sense Datum Theory; second, to resolve these puzzles by reconstructing the Trilemma Argument; third to point to a distinction Sellars makes between two versions of the Sense Datum Theory, the “nominalist” version and the “realist” version; fourth, to reconstruct Sellars’s arguments against both; and, finally, to find in an earlier paper, “Is There a Synthetic A Priori?” that his argument (...) against the second version, assumed but not actually given in EPM, is against property realism and depends on taking language expressing propositional perception as fundamental and language expressing non-propositional perception as incomplete and derivative from the former.

Conceptual Metaphor Theory makes some strong claims against so-called Classical Theory which spans the accounts of metaphors from Aristotle to Davidson. Most of these theories, because of their traditional literal-metaphorical distinction, fail to take into account the phenomenon of conceptual metaphor. I argue that the underlying mechanism for explaining metaphor bears some striking resemblances among all of these theories. A mapping between two structures is always expressed. Conceptual Metaphor Theory insists, however, that the literal-metaphorical distinction of Classical Theories (...) is empirically wrong. I claim that this criticism is based rather on terminological decisions than on empirical issues. Conceptual Metaphor Theory focusses primarily on conventional metaphors and struggles to extend its mechanism to novel metaphors, whereas Classical Theories focus on novel metaphors and struggle to extend their mechanisms to conventional metaphors. Since all of these theories study metaphors from the synchronic point of view, they are unable to take into account any semantic change. A diachronic perspective is what we need here, one which would allow us to explain the role of metaphor in semantic change and the development of language in general. (shrink)

The present volume is a sequel to Deontic Logic: Introductory and Systematic Readings : its purpose is to offer a view of some of the main directions of research in contemporary deontic logic. Most of the articles included in Introductory and Systematic Readings represent what may be called the standard modal approach to deontic logic, in which de on tic logic is treated as a branch of modal logic, and the normative concepts of obligation, permission and prohibition are regarded as (...) analogous to the "alethic" modalities necessity, possibility and impossibility. As Simo Knuuttila shows in his contribution to the present volume, this approach goes back to late medieval philosophy. Several 14th century philosophers observed the analogies between deontic and alethic modalities and discussed the deontic interpretations of various laws of modal logic. In contemporary deontic logic the modal approach was revived by G. H. von Wright's classic paper 'Deontic Logic'. Certain analogies between deontic and alethic modalities are obvious and uncontroversial, but the standard approach has often been criticized on the ground that it exaggerates the analogies and tends to ignore those features of normative concepts which distinguish them from other modalities.

Although the relationship of part to whole is one of the most fundamental there is, this is the first full-length study of this key concept. Showing that mereology, or the formal theory of part and whole, is essential to ontology, Simons surveys and critiques previous theories--especially the standard extensional view--and proposes a new account that encompasses both temporal and modal considerations. Simons's revised theory not only allows him to offer fresh solutions to long-standing problems, but also has far-reaching consequences for (...) our understanding of a host of classical philosophical concepts.

In this paper, we defend Socratic studies as a research programme against several recent attacks, including at least one recently published in Polis . Critics have argued that the study of Socrates, based upon evidence mostly or entirely derived from some set of Plato's dialogues, is founded upon faulty and indefensible historical or hermeneutical technique. We begin by identifying what we believe are the foundational principles of Socratic studies, as the field has been pursued in recent years, and (...) we then show how the research programme that derives from accepting these principles is not defeated by any of the most common recent criticisms of it. Specifically, we argue that challenges to sorting Plato's dialogues by date, more general challenges to historicist interpretations of Plato's dialogues, as well as recent literary criticisms of Socratic studies all fail to undermine the research programme. We conclude with some thoughts about how and why Socratic studies has proved itself a valuable and fruitful research programme. (shrink)

The classification of algebraic surfaces by the Italian School of algebraic geometry is universally recognized as a breakthrough in 20th-century mathematics. The methods by which it was achieved do not, however, meet the modern standard of rigor and therefore appear dubious from a contemporary viewpoint. In this article, we offer a glimpse into the mathematical practice of the three leading exponents of the Italian School of algebraic geometry: Castelnuovo, Enriques, and Severi. We then bring into focus their distinctive conception of (...) rigor and intuition. Unlike what is often assumed today, from their perspective, rigor is neither opposed to intuition nor understood as a unitary phenomenon – Enriques distinguishes between small-scale rigor and large-scale rigor and Severi between formal rigor and substantial rigor. Finally, we turn to the notion of mathematical objectivity. We draw from our case study in order to advance a multi-dimensional analysis of objectivity. Specifically, we suggest that various types of rigor may be associated with different conceptions of objectivity: namely, objectivity as faithfulness to facts and objectivity as intersubjectivity.

Serotonergic (or “classic”) psychedelics have struck many researchers as raising significant philosophical questions that, until recently, were largely unexplored by academic philosophers. This paper provides an overview of four emerging lines of research at the intersection of academic philosophy and psychedelic science that have gained considerable traction in the last decade: selfless consciousness, psychedelic epistemology, psychedelic ethics, and spiritual/religious naturalism. In this paper, we highlight philosophical questions concerning (i) psychedelics, self-consciousness, and phenomenal consciousness, (ii) the epistemic profile of the psychedelic (...) experience; (iii) ethical concerns about the appropriate use of psychedelics; and (iv) whether spiritual or religious dimensions of psychedelic use are compatible with a naturalistic worldview.

There are some tantalizing suggestions that Pyrrhonian skepticism has its roots in ancient India. Of them, the most important is Diogenes Laertius’s report that Pyrrho accompanied Alexander to India, where he was deeply impressed by the character of the “naked sophists” he encountered (DL IX 61). Influenced by these gymnosophists, Pyrrho is said to have adopted the practices of suspending judgment on matters of belief and cultivating an indifferent composure amid the vicissitudes of ordinary life. Such conduct, and the attitudes (...) that it embodied, became inspirations to later skeptical thinkers. It is a fact that practices of the sort attributed to Pyrrho are richly evident in a number of ancient Indian philosophical and ascetic movements. On this basis, attempts have been made to determine the identity of these gymnosophists and, further, to pinpoint the dialectical tropes within Pyrrhonism that may have their basis in Indian thought. But despite these attempts, and in the absence of any new discoveries, these suggestions will likely remain just that. The paucity of the historical data and the problematic nature of the data itself prevent us from reconstructing a solid bridge between ancient India and Greek skepticism that may serve as the basis of robust historical theorizing. Classical India does, however, lay claim to a sophisticated and diverse culture of epistemological reflection, which includes a number of innovative skeptical thinkers deserving study on their own merits. This chapter is meant to provide such a study, or perhaps more accurately, a prolegomena for such. After some initial ground-laying, I will discuss three leading Indian skeptics and situate them historically and conceptually within the network of competing schools that comprise classical Indian philosophy. They are Nāgārjuna (c. 150 CE), the founder of Madhyamaka Buddhism, Jayarāśi (c. 800), associated with the Indian materialist tradition, and Śrīharṣa (c. 1150), a thinker connected to the school of Nondual (Advaita) Vedānta.

We argue against claims that the classical ℏ → 0 limit is “singular” in a way that frustrates an eliminative reduction of classical to quantum physics. We show one precise sense in which quantum mechanics and scaling behavior can be used to recover classical mechanics exactly, without making prior reference to the classical theory. To do so, we use the tools of strict deformation quantization, which provides a rigorous way to capture the ℏ → 0 limit. (...) We then use the tools of category theory to demonstrate one way that this reduction is explanatory: it illustrates a sense in which the structure of quantum mechanics determines that of classical mechanics.

Air is one of the five classical elements, which make all the creation. We can perceive air in the things it moves, be it leaves or hair. It is an invisible mixture of nitrogen, oxygen, and minute amounts of other gases surrounding the Earth. It is all around us. Yet, we cannot see it. Pure air has no odour. It has many uses. It provides a breath of life to all living beings. As, atmosphere, it prevents the excessive heat (...) of the Sun from reaching us. Oxygen, one of its constituents, supports combustion. Thereby it helps us to cook food, generate heat and electricity, run industries and drive vehicles. Its other two components, nitrogen and carbon dioxide, are essential for the growth of plants. Another beneficial constituent of air is Ozone, which in the form of the Ozone layer around our planet protects us from the adverse effects of the Sun's UV rays. Compressed air is used to fill tyres. Many machines and drills work on compressed air. Wind enables the movement of sailboats and gliders. It runs windmills to generate electricity and helps in the dispersal of seeds. Guru Arjan appreciating the priceless importance of air to all of us articulates [1-2]; He (Creator) gave you the invaluable air. (Mehl 5, SGGS, p 913). (shrink)

We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in particular the case of a bipartite decomposition into "system" and "environment." Such a decomposition can be defined by looking for subsystems that exhibit quasi-classical behavior. The correct decomposition is one in which pointer states of the system are relatively robust against environmental monitoring (their entanglement with the environment does not continually and dramatically increase) and (...) remain localized around approximately-classical trajectories. We present an in-principle algorithm for finding such a decomposition by minimizing a combination of entanglement growth and internal spreading of the system. Both of these properties are related to locality in different ways. This formalism could be relevant to the emergence of spacetime from quantum entanglement. (shrink)

This thesis is a study of the notion of time in modern physics, consisting of two parts. Part I takes seriously the doctrine that modern physics should be treated as the primary guide to the nature of time. To this end, it offers an analysis of the various conceptions of time that emerge in the context of various physical theories and, furthermore, an analysis of the relation between these conceptions of time and the more orthodox philosophical views on the nature (...) of time. In Part II I explore the interpretation of nonrelativistic quantum mechanics in light of the suggestion that an overly Newtonian conception of time might be contributing to some of the difficulties that we face in interpreting the quantum mechanical formalism. In particular, I argue in favour of introducing backwards-in-time causal influences as part of an alternative conception of time that is consistent with the picture of reality that arises in the context of the quantum formalism. Moreover, I demonstrate that this conception of time can already be found in a particular formulation of classical mechanics. One might see that one of the central themes of Part II originates from a failure to heed properly the doctrine of Part I: study into the nature of time should be guided by modern physics and thus we should be careful not to insert a preconceived Newtonian conception of time unwittingly into our interpretation of the quantum mechanical formalism. Thus, whereas Part I is intended as a demonstration of methodology with respect to the study of time, Part II in a sense explores a confusion that can be seen as arising in the absence of this methodology.

In 1597 Francisco Suárez published a comprehensive treatise on beings of reason (entia rationis) as part of his Disputationes metaphysicae. Subsequent scholastic philosophers vigorously debated various aspects of Suárez’s theory. The aim of this paper is to identify some of the most controversial points of these debates, as they developed in the first half of the seventeenth century. In particular, I focus on the intension and the extension of ‘ens rationis’, its division (into negations, privations and relations of reason) and (...) its causes. Additionally, I will discuss how Suárez’s views sparked a number of debates within the classical view, debates which ultimately led to the emergence of various alternative theories, especially among the Jesuits. These non-classical views radically revise the previous classical conception of beings of reason. (shrink)

The new inter-disciplinary eclecticism championed by many philosophers of science has generated a heterogeneous family of science studies projects. Philosophers who favor an inter-disciplinary approach face many problems if they are to successfully forge a hybrid science studies that does not violate their integrity as philosophers in particular, they must isolate an intellectual space in which traditional agendas, such as the concern for the clarification of concepts, can hold court. In this paper, I outline what I regard as (...) a new brand of HPS, one that is deeply rooted in the history of the exact science. The virtue of this New HPS, I will submit, is that it furnishes philosophers of science with a fresh perspective from which to carry on philosophy's classic normative mission. (shrink)

As part of our small contribution in dialogue toward better peace development and reconciliation studies, and following Toffler & Toffler’s War and Antiwar (1993), the present article delves into a realm of logic beyond the traditional confines of negation and the excluded middle principle, exploring the nuances of "Otherness" that transcend classical and Nagatomo logics. Departing from the foundational premises of classical Aristotelian logic systems, this exploration ventures into alternative realms of reasoning, specifically examining Neutrosophic Logic and (...) Klein bottle logic (cf. Smarandache, 2005). The study challenges conventional boundaries and explores the implications of embracing paradoxes and self-reference in logic systems, aiming to redefine approaches to understanding truth and reasoning. The paper investigates how these alternative logics open avenues for philosophical inquiry, redefining entropy, and potentially influencing innovative perspectives in free energy systems. Through this exploration, it seeks to expand the discourse on logic, welcoming a broader spectrum of thought beyond established frameworks; and we also discuss shortly a number of possible implementations including in risk management and also Klein bottle entropy redefinition (Tang et al, 2018).

Interdisciplinary or team-taught courses pose special challenges and make special demands on the instructors. Yet they also offer special opportunities for learning—for instructor and student alike. This paper describes one such course taught at the University of Maryland by a historian (Kenneth Holum), an art historian (Elisabeth Pemberton), and a philosopher (James Lesher), focused on the art, politics, and philosophical environment of 5th-century Athens. Three themes emerged over the course of the semester: the centrality of the family in Athenian society, (...) the emergence of the individual as a new focus of interest in art and society, human nature as a new subject of study, and the phenomenon of cross-fertilization or ‘bi-sociation’ as the ideas developed in one field were adapted for use in other disciplines. For all their special burdens and challenges, courses such as this one can provide an opportunity to explore philosophical theorizing from a new perspective. (shrink)

Wang Yangming (1472-1529) and his School of Mind dominated the intellectual world of sixteenth-century Ming China (1368-1644), and his Confucian philosophy has since remained an essential component of East Asian philosophical discourse. Yet, the volume of publications on him in the Western-language literature has consistently paled in comparison to the volume of scholarship on classical Chinese philosophy, modern Chinese philosophy, Buddhism, and Daoism. Studying Wang Yangming: History of a Sinological Field explains the history of writing in the West about (...) the famed Ming dynasty scholar-official. From eighteenth-century French Jesuit books to English-language publications in 2020, this book provides a historical overview and summary of a literature published by scholars attempting to grapple with one of the most influential Confucians in the history of China, East Asia, and the world.

A collection of material on Husserl's Logical Investigations, and specifically on Husserl's formal theory of parts, wholes and dependence and its influence in ontology, logic and psychology. Includes translations of classic works by Adolf Reinach and Eugenie Ginsberg, as well as original contributions by Wolfgang Künne, Kevin Mulligan, Gilbert Null, Barry Smith, Peter M. Simons, Roger A. Simons and Dallas Willard. Documents work on Husserl's ontology arising out of early meetings of the Seminar for Austro-German Philosophy.

This is a translation of an article published in the journal Argeiaki Ge, which was asked from me by the scientific journal Journal of Classical Studies Matica Srpska. The Argive Hapocration was a philosopher and commentator from the second century A.D. His origin is not disputed by any source. However, there is still a potential possibility that he might have descended from a different Argos: namely that which is in Amfilochia, Orestiko or that in Cyprus. Yet, the absence (...) of any additional geographical designation in his name in ancient sources is likely to disprove such claims. Simply mentioning ‘Argos’ can only indicate the most notable of the cities with this name, namely the Argive Argos. As will be revealed later in this paper, the close relationship between Hapocration with the Atticus family may well support his Argive origin. I support that it is obvious to assume that there is a close affinity of philosophical activity in Phlius and in Argos which remains to be investigated in more detail in the future. The research of written and archaeological sources can flourish further still. I hope that in the near future there will be evidence enough for a fuller presentation of philosophical activity in ancient Argos. (shrink)

In this thesis I argue against unrestricted mereological hybridism, the view that there are absolutely no constraints on wholes having parts from many different logical or ontological categories, an exemplar of which I take to be ‘mixed fusions’. These are composite entities which have parts from at least two different categories – the membered (as in classes) and the non-membered (as in individuals). As a result, mixed fusions can also be understood to represent a variety of cross-category summation such as (...) the abstract with the concrete, the physical with the non-physical, and the possible with the impossible, just to name a few. -/- Proposed by David Lewis (1991) alongside his defence of classical mereology (the major theory of parthood which permits such transcategorial composites through its principle of unrestricted composition) it is my contention that mixed fusions are an under-examined consequence of indiscriminate mereological fusion which harbour a multitude of complications. In my attempt to discern their substantive character, throughout this thesis I make a case study of mixed fusions and uncover several problematic consequences which I think follow from their most plausible assessment. -/- These include: (1) that mixed fusions’ probable membership relations may lead to dubious foundational loops in the mereological Universe, or (2) otherwise that mixed fusions oblige an implausible ontological priority of the mereological Universe as a whole; (3) that mixed fusions contradict the reductive account of set theory they are proposed within, by plausibly being seen to have the same members as their class parts, and (4) that mixed fusions therefore confound a mereological thesis of Composition as Identity, which some (including Lewis) use to support classical mereology – a consequence which is potentially self-defeating; (5) that mixed fusions as sums of abstract and concrete entities both subvert Lewis’s (1986) system of modal realism, while (6) also undermining less expansive theories of possible worlds; and finally, (7) that even where some of the foregoing is resisted, it remains implausible that mixed fusions are ontologically innocent, because their supposed distinction from their parts in this case ensures that they need to be counted as additional entities in one’s ontology. -/- To be clear, I do not advance a theory of mereological hybrid nihilism in the sense of denying all cases of transcategorial composition. (I only cover a few select instances of mereological hybridism via mixed fusions after all.) Rather, I deny that mereological hybridism is plausible in full generality, by demonstrating that any cases of it are at least limited by the constraints that I identify. This in turn vindicates a call for a restriction on parthood theories and composition principles which allow certain types of categorially mixed entities – including restricting classical mereology with its principle of unrestricted composition. -/- Although theories of parthood like the standard classical mereology are not ordinarily developed for the sake of mereological hybrids like mixed fusions, these and other transcategorial composites are still among the logical consequences of such parthood systems operating with sufficient generality. The significance of my thesis, then, comes from showcasing how some of these kinds of entities do not conform to the systems in which they are included as required, and hence I argue for the rejection of unrestricted mereological hybridism as well as any mereological principles which support it.

5-MeO-DMT is a psychedelic substance with a short duration of action and intensive effects. Its therapeutic efficacy and practicality may significantly surpass those of classical psychedelics such as ayahuasca and LSD. -/- This retrospective ethnographic inquiry features a woman in her mid-thirties who witnessed her mother's violent suicide and its bloody aftermath at the age of three. Before and after that, her childhood was characterized by domestic violence and sexual abuse perpetrated by several members of her family and extended (...) family. In her twenties and thirties, she dated a member of the local mafia with the intention of asking him to kill her father, who had been the main perpetrator of the sexual abuse and violence. This plan was eventually not carried out, but it reflected her deep bitterness and wrath. -/- A process initiated in her early thirties involving four 5-MeO-DMT sessions and a few additional sessions with psilocybin and ayahuasca in the course of two years completely resolved her symptoms related to the abuses, to the extent that she could rebuild a functional relationship with her father and feel love and compassion towards him. This outcome, i.e., the complete reversal of her attitude and emotions towards her father, appeared highly unusual. For the last three years, the outcome had remained stable. -/- The article also presents the perspective of a female facilitator of this treatment process. The article contributes to a better understanding of the use of 5-MeO-DMT in severe traumatization as well as exemplifies the possible positive contributions of actors who are not medical professionals in resolving deep collective traumatization in societies.

In this paper I investigate, within the framework of realistic interpretations of the wave function in nonrelativistic quantum mechanics, the mathematical and physical nature of the wave function. I argue against the view that mathematically the wave function is a two-component scalar field on configuration space. First, I review how this view makes quantum mechanics non- Galilei invariant and yields the wrong classical limit. Moreover, I argue that interpreting the wave function as a ray, in agreement many physicists, Galilei (...) invariance is preserved. In addition, I discuss how the wave function behaves more similarly to a gauge potential than to a field. Finally I show how this favors a nomological rather than an ontological view of the wave function. (shrink)

Developing earlier studies of the system of numbers in Mundurucu, this paper argues that the Mundurucu numeral system is far more complex than usually assumed. The Mundurucu numeral system provides indirect but insightful arguments for a modular approach to numbers and numerals. It is argued that distinct components must be distinguished, such as a system of representation of numbers in the format of internal magnitudes, a system of representation for individuals and sets, and one-to-one correspondences between the numerosity expressed (...) by the number and its metrics. It is shown that while many-number systems involve a compositionality of units, sets and sets composed of units, few-number languages, such as Mundurucu, do not have access to sets composed of units in the usual way. The nonconfigurational character of the Mundurucu language, which is related to a property for which we coin the term 'low compositionality power', accounts for this and explains the curious fact that Mundurucus make use of marked one-to-one correspondence strategies in order to overcome the limitations of the core system at the perceptual/motor interface of the language faculty. We develop an analysis of a particular construction, parallel numbers, which has not been studied before, elucidating the whole system. This analysis, we argue, sheds new light on classical philosophical, psychological and linguistic debates about numbers and numerals and their relation to language, and more particularly, sheds light on few-number languages.

The stated intent of the volume is "to broaden the exposure of Chinese Studies outside America and Great Britain" (p. vii). In this respect, the book succeeds admirably, as one of its distinctive features is the introduction of German scholarly approaches to an Anglo-American audience. As this fills a lacuna in Chinese studies, this volume is to be welcomed.

A major question in sensory science is how a sensation of magnitude F (such as loudness) depends upon a sensory stimulus of physical intensity I (such as a sound-pressure-wave of root-mean-square sound-pressure-level). An empirical just-noticeable sensation difference (∆F)_j at F_j specifies a just-noticeable intensity difference (∆I)_j at I_j. Classically, intensity differences accumulate from a stimulus-detection threshold I_th up to a desired intensity I. The corresponding sensation differences likewise accumulate up to F(I) from F(I_th ), the non-zero sensation (as suggested by (...) hearing studies) at I_th. Consequently, sensation growth F(I) can be obtained through classic Fechnerian integration, in which some empirically-based relation for the Weber Fraction, ∆I⁄I, is combined with either Fechner’s Law ∆F=B or Ekman’s Law (∆F⁄F)=g. The number of steps in I is equated to the number of steps in F; an infinite series ensues, whose higher-order terms are traditionally ignored (Fechnerian integration). But also, remarkably, so are the integration bounds I_th and F(I_th ). Here, we depart from orthodoxy by including those bounds. Bounded Fechnerian integration is first used to derive hypothetical sensation-growth equations for which the differential ∆F(I)=F(I+∆I)-F(I) does indeed return either Fechner’s Law or Ekman’s Law respectively. One relation emerges: linear growth of sensation F with intensity I. Subsequently, 24 sensation-growth equations F(I) that the author had derived using bounded Fechnerian integration (12 equations for the Weber Fraction (∆I⁄I), each combined with either Fechner’s Law or with Ekman’s Law) are scrutinized for whether their differentials F(I+∆I)-F(I) return the respective Fechner’s Law or Ekman’s Law, particularly in the previously-unexamined limits (∆I⁄I)≪1 and (∆I⁄I)→0. Classic claims made by Luce and Edwards (1958) are then examined, viz., that three popular forms of the Weber Fraction, when combined with Fechner’s Law, produce sensation-magnitude equations that subsequently return the selfsame Fechner’s Law. When sensation-growth equations are derived here using bounded Fechnerian integration, Luce and Edwards (1958) prove to be wrong. (shrink)
