The paper begins with an argument against eliminativism with respect to the propositional attitudes. There follows an argument that concepts are sui generis ante rem entities. A nonreductionist view of concepts and propositions is then sketched. This provides the background for a theory of concept possession, which forms the bulk of the paper. The central idea is that concept possession is to be analyzed in terms of a certain kind of pattern of reliability in one’s intuitions regarding the (...) behavior of the concept. The challenge is to find an analysis that is at once noncircular and fully general. Environmentalism, anti-individualism, holism, analyticity, etc. provide additional hurdles. The paper closes with a discussion of the theory’s implications for the Wittgenstein-Kripke puzzle about rule-following and the Benacerraf problem concerning mathematical knowledge. (shrink)

In this paper, I argue that descriptive information associated with concepts plays a relevant role in the performance of different cognitive tasks, as suggested by Descriptivist Theories of Concepts (DTC). However, I argue that it does not follow that such information determines the extension of concepts, as also suggested by DTC. In support of these claims, I present an analysis of empirical evidence offered by cases of semantic dementia. According to this interpretation of such evidence, the (...) information associated with concepts is part of the cognitive content of concepts. It is involved in different cognitive tasks, but such evidence does not support the thesis that it is possible to determine the intentional content, i.e., the extension of a concept from the cognitive content, since to do so would face the objection of ignorance.

In this article, the authors try to answer the following questions: How can an object/instance seen for the first time extend a category or update a concept? How is it possible to determine the reference of a concept that represents a behaviour? In the first case, the authors discuss the learning of inferential linguistic competence used to update a concept through an approach based on prototype theory. In the second case, the authors discuss the learning of referential linguistic competence used (...) to determine the reference of a concept (i.e., determination of an actual behaviour) through an approach based on embodied cognition. The authors show how combining prototype-based and embodied categorization in Wittgenstein’s rule-following praxis (the individual and community dimension), linguistic learning of a concept (inferential competence), and determination of its reference (referential competence) can be traced back to the same model.

Our computational metaphysics group describes its use of automated reasoning tools to study Leibniz’s theory of concepts. We start with a reconstruction of Leibniz’s theory within the theory of abstract objects (henceforth ‘object theory’). Leibniz’s theory of concepts, under this reconstruction, has a non-modal algebra of concepts, a concept-containment theory of truth, and a modal metaphysics of complete individual concepts. We show how the object-theoretic reconstruction of these components of Leibniz’s theory can be represented for investigation (...) by means of automated theorem provers and finite model builders. The fundamental theorem of Leibniz’s theory is derived using these tools. (shrink)

The emotion theory of concepts maintains that concepts may be in part constituted by sentiments and emotions. Very few works in the contemporary concepts literature discuss this possibility that concepts may be sentiments and emotions, and those that do discuss this possibility ultimately fail to establish the viability of this view. However, by in part relying on experimental evidence from psychology and neuroscience, I contend that some concrete and abstract concepts are in part constituted by (...) sentiments and emotions.

The aim of this paper is to describe and analyze the epistemological justification of a proposal initially made by the biomathematician Robert Rosen in 1958. In this theoretical proposal, Rosen suggests using the mathematical concept of “category” and the correlative concept of “natural equivalence” in mathematical modeling applied to living beings. Our questions are the following: According to Rosen, to what extent does the mathematical notion of category give access to more “natural” formalisms in the modeling of living beings? Is (...) the so -called “naturalness” of some kinds of equivalences (which the mathematical notion of category makes it possible to generalize and to put at the forefront) analogous to the naturalness of living systems? Rosen appears to answer “yes” and to ground this transfer of the concept of “natural equivalence” in biology on such an analogy. But this hypothesis, although fertile, remains debatable. Finally, this paper makes a brief account of the later evolution of Rosen’s arguments about this topic. In particular, it sheds light on the new role played by the notion of “category” in his more recent objections to the computational models that have pervaded almost every domain of biology since the 1990s.

In this thesis I argue that the psychological study of concepts and categorisation, and the philosophical study of reference are deeply intertwined. I propose that semantic intuitions are a variety of categorisation judgements, determined by concepts, and that because of this, concepts determine reference. I defend a dual theory of natural kind concepts, according to which natural kind concepts have distinct semantic cores and non-semantic identification procedures. Drawing on psychological essentialism, I suggest that the cores (...) consist of externalistic placeholder essence beliefs. The identification procedures, in turn, consist of prototypes, sets of exemplars, or possibly also theory-structured beliefs. I argue that the dual theory is motivated both by experimental data and theoretical considerations. The thesis consists of three interrelated articles. Article I examines philosophical causal and description theories of natural kind term reference, and argues that they involve, or need to involve, certain psychological elements. I propose a unified theory of natural kind term reference, built on the psychology of concepts. Article II presents two semantic adaptations of psychological essentialism, one of which is a strict externalistic Kripkean-Putnamian theory, while the other is a hybrid account, according to which natural kind terms are ambiguous between internalistic and externalistic senses. We present two experiments, the results of which support the strict externalistic theory. Article III examines Fodor’s influential atomistic theory of concepts, according to which no psychological capacities associated with concepts constitute them, or are necessary for reference. I argue, contra Fodor, that the psychological mechanisms are necessary for reference. (shrink)

Ao mesmo tempo que o malogro da assim chamada teoria clássica dos conceitos - de acordo com a qual definições são a maneira apropriada de caracterizar conceitos - é um consenso, a filosofia metafísica da religião parece ainda lidar com o conceito de Deus de forma predominantemente definicional. Podemos então nos perguntar: Seria esse malogro suficiente para inviabilizar uma caracterização definicional do conceito de Deus? Meu propósito central neste artigo é responder essa pergunta. Adoto uma ênfase representacional. Em outras palavras, (...) desejo analisar até que ponto os problemas mais importantes levantados contra a teoria clássica dos conceitos afetam uma abordagem definicional-representacional do conceito de Deus. Como resultado desse esforço, mostro que as críticas à teoria clássica que ameaçam tal abordagem dependem da pluralidade característica ao contexto inter-religioso, que por si só cria outros problemas.

John McDowell’s debates about concepts with Robert Brandom and Hubert Dreyfus over the past two decades reveal key commitments each philosopher makes. McDowell is committed to giving concepts a role in our embodied coping, extending rational form to human experience. Brandom is committed to defining concepts in a way that helps make rationality distinct. And Dreyfus is committed to explaining how rational understanding develops out of lesser abilities we share with human infants and other animals (I call (...) this “Dreyfus’s challenge”). These commitments appear irreconcilable. I argue to the contrary that they are, in principle, reconcilable, provided we give up their shared “rationalist” commitment to the idea that the rational use of language is necessary for having concepts. First, I exploit Brandom and McDowell’s debate to motivate abandoning the rationalist commitment. Next, I exploit Dreyfus and McDowell’s debate to establish the need for a broader notion of concepts to answer Dreyfus’s challenge. I turn to Elizabeth Camp’s broader notion of concepts as spontaneously, systematically recombinable representations, and establish that it lacks resources for distinguishing human rationality. To resolve that weakness, I integrate Camp’s notion of concepts with John Haugeland’s theory of objectivity, which does make rationality distinct. Finally, drawing my integration of Camp and Haugeland, I propose a way to answer Dreyfus’s challenge, which I call “relaxed holism.” The core of relaxed holism is a cumulative, developmental sequence of three related cognitive abilities: representation, concepts, and metacognition. I argue that relaxed holism also reconciles both McDowell’s commitment to giving normatively governed concepts a role in embodied coping, and Brandom’s commitment to defining concepts in a way that helps make rationality distinct.

I have two major aims in this chapter, which is philosophical in nature. One is to draw upon values that are salient in the southern African region in order to construct a novel and attractive conception of human dignity. Specifically, I articulate the idea that human beings have a dignity in virtue of their communal nature, or their capacity for what I call ‘identity’ and ‘solidarity’, which contrasts the most influential conception in the West, according to which our dignity inheres (...) in our rationality or autonomy. The second aim is to invoke this Afro-communitarian conception of human dignity in order to advance a new conception of why poverty is morally problematic and of what people, particularly states, are ethically required to do with regard to it. Common conceptions of poverty focus on it in terms of people lacking income, preference satisfaction (‘utility’) or general-purpose means (‘social primary goods’ in the Rawlsian jargon). In contrast, if what is special about human beings is our ability to commune with one another in a certain way, then the respects in which poverty can be an injustice and the ways that it must be fought must be understood in more communitarian or relational terms, which I both specify with several concrete examples in a South African context and contrast with the more dominant approaches.

We argue that many recent philosophical discussions about the reference of everyday concepts of intentional states have implicitly been predicated on descriptive theories of reference. To rectify this, we attempt to demonstrate how a causal theory can be applied to intentional concepts. Specifically, we argue that some phenomena in early social de- velopment ðe.g., mimicry, gaze following, and emotional contagionÞ can serve as refer- ence fixers that enable children to track others’ intentional states and, thus, to refer (...) to those states. This allows intentional concepts to be anchored to their referents, even if folk psy- chological descriptions turn out to be false. (shrink)

We introduce a family of operators to combine Description Logic concepts. They aim to characterise complex concepts that apply to instances that satisfy \enough" of the concept descriptions given. For instance, an individual might not have any tusks, but still be considered an elephant. To formalise the meaning of "enough", the operators take a list of weighted concepts as arguments, and a certain threshold to be met. We commence a study of the formal properties of these operators, (...) and study some variations. The intended applications concern the representation of cognitive aspects of classi cation tasks: the interdependencies among the attributes that de ne a concept, the prototype of a concept, and the typicality of the instances.

The issue of the definition and position of archaeology as a discipline is examined in relation to the dispute which took place from 1980 to 2009 between the archaeologist Jean-Claude Gardin and the sociologist Jean-Claude Passeron. This case study enables us to explore the actual conceptual relationships between archaeology and the other sciences (as opposed to those wished for or prescribed). The contrasts between the positions declared by the two researchers and the rooting of their arguments in their disciplines are (...) examined: where the sociologist makes use of his philosophical training, the archaeologist relies mainly on his work on semiology and informatics. Archaeology ultimately plays a minor role in the arguments proposed. This dispute therefore cannot be considered as evidence for the movement of concepts between archaeology and the social sciences. A blind spot in the debate, relating to the ontological specificities of archaeological objects, nevertheless presents itself as a possible way of implementing this movement. (shrink)

Conceptual engineering is the method for assessing and improving our concepts. However, little has been written about how best to conceive of concepts for the purposes of conceptual engineering. In this paper, I aim to fill this foundational gap, proceeding in three main steps: First, I propose a methodological framework for evaluating the conduciveness of a given concept of concept for conceptual engineering. Then, I develop a typology that contrasts two competing concepts of concept that can be (...) used in conceptual engineering — namely, the philosophical and psychological ones. Finally, I evaluate these two concepts of concept using the proposed methodological framework and I show that, when it comes to making conceptual engineering an actionable method, the psychological concept of concept outclasses its philosophical counterpart on all counts. This provides a baseline from which the concept of concept can be further improved for the purposes of conceptual engineering. (shrink)

I find it interesting that AI researchers don't use concepts very often in their theorizing. No doubt they feel no pressure to. This is because most AI researchers do use representations which allow a system to chunk up its environment, and basically all we know about concepts is that they are representations which allow a system to chunk up its environment.

There are many views about the structure of concepts, a plausible one of which is the theory-theory. Though this view is plausible for concrete concepts, it is unclear that it would work for abstract concepts, and then for moral concepts. The goal of this paper is to provide a plausible theory-theory account for moral concepts and show that it is supported by results in the moral psychology literature. Such studies in moral psychology do not explicitly (...) contend for the theory-theory of moral concepts, but I demonstrate that they actually do provide evidence for the use of theory knowledge at times in moral categorization and decision-making. In philosophy of cognitive science, I newly show that there is evidence that the theory-theory does apply to some moral concepts. (shrink)

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the theory of concept (...) possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

# Theory of Harmonic Time (THT): A Speculative Framework *Disclaimer* This paper presents a highly speculative and theoretical framework, exploring potential connections between harmonic time and various established theories. The ideas discussed herein are hypothetical and require further development, refinement, and experimental verification. *Introduction* The Theory of Harmonic Time (THT) proposes that harmonic oscillations underlie the fundamental nature of time and the universe. This framework attempts to integrate concepts from various theories, including String Theory/M-Theory, Loop Quantum Gravity (...) (LQG), Causal Dynamical Triangulation (CDT), Asymptotic Safety, and Emergent Gravity. *THT-String Theory Proposal* Consider the harmonic oscillations of strings in String Theory/M-Theory. These oscillations give rise to a fractal structure, where the same harmonic patterns repeat at different scales. This fractal structure could be the fundamental unit of time. *THT-LQG Proposal* In LQG, consider the spin networks and holonomies that give rise to the fabric of spacetime. Introduce harmonic resonance, where spin networks and holonomies exhibit harmonic oscillations. These oscillations could give rise to a fractal structure. *THT-CDT Proposal* In CDT, consider the discretized spacetime, composed of simple geometric building blocks. Introduce harmonic oscillations, where these building blocks exhibit harmonic resonance. This resonance could give rise to a fractal structure. *THT-Asymptotic Safety Proposal* In Asymptotic Safety, consider gravitational waves and fluctuations. Introduce harmonic resonance, where these fluctuations exhibit harmonic oscillations. These oscillations could give rise to a fractal structure. *THT-Emergent Gravity Proposal* In Emergent Gravity, consider the collective behavior of particles. Introduce harmonic resonance, where particles exhibit harmonic oscillations. These oscillations could give rise to a fractal structure. *Conclusion* The Theory of Harmonic Time (THT) presents a speculative framework, attempting to integrate harmonic oscillations with various established theories. While highly speculative, this framework might offer new insights into the nature of time and the universe. Further development, refinement, and experimental verification are necessary to explore the potential implications of THT. (shrink)

This essay critically examines some classic philosophical and legal theories of privacy, organized into four categories: the nonintrusion, seclusion, limitation, and control theories of privacy. Although each theory includes one or more important insights regarding the concept of privacy, I argue that each falls short of providing an adequate account of privacy. I then examine and defend a theory of privacy that incorporates elements of the classic theories into one unified theory: the Restricted Access/Limited Control (RALC) theory (...) of privacy. Using an example involving data-mining technology on the Internet, I show how RALC can help us to frame an online privacy policy that is sufficiently comprehensive in scope to address a wide range of privacy concerns that arise in connection with computers and information technology.

The aims of this paper are to: (1) identify the best framework for comprehending multidimensional impact of deep brain stimulation on the self; (2) identify weaknesses of this framework; (3) propose refinements to it; (4) in pursuing (3), show why and how this framework should be extended with additional moral aspects and demonstrate their interrelations; (5) define how moral aspects relate to the framework; (6) show the potential consequences of including moral aspects on evaluating DBS’s impact on patients’ selves. Regarding (...) (1), I argue that the pattern theory of self can be regarded as such a framework. In realizing (2) and (3), I indicate that most relevant issues concerning PTS that require resolutions are ontological issues, including the persistence question, the “specificity problem”, and finding lacking relevant aspects of the self. In realizing (4), I identify aspects of the self not included in PTS which are desperately needed to investigate the full range of potentially relevant DBS-induced changes—authenticity, autonomy, and responsibility, and conclude that how we define authenticity will have implications for our concept of autonomy, which in turn will determine how we think about responsibility. Concerning (5), I discuss a complex relation between moral aspects and PTS—on one hand, they serve as the lens through which a particular self-pattern can be evaluated; on the other, they are, themselves, products of dynamical interactions of various self-aspects. Finally, I discuss (6), demonstrating novel way of understanding the effects of DBS on patients’ selves. (shrink)

This is a contribution to the symposium on Herman Cappelen’s book Fixing Language. Cappelen proposes a metasemantic framework—the “Austerity Framework”—within which to understand the general phenomenon of conceptual engineering. The proposed framework is austere in the sense that it makes no reference to concepts. Conceptual engineering is then given a “worldly” construal according to which conceptual engineering is a process that operates on the world. I argue, contra Cappelen, that an adequate theory of conceptual engineering must make reference to (...) concepts. This is because concepts are required to account for topic continuity, a phenomenon which lies at the heart of projects in conceptual engineering. I argue that Cappelen’s own account of topic continuity is inadequate as a result of the austerity of his metasemantic framework, and that his worldly construal of conceptual engineering is untenable.

According to the computational theory of mind , to think is to compute. But what is meant by the word 'compute'? The generally given answer is this: Every case of computing is a case of manipulating symbols, but not vice versa - a manipulation of symbols must be driven exclusively by the formal properties of those symbols if it is qualify as a computation. In this paper, I will present the following argument. Words like 'form' and 'formal' are ambiguous, as (...) they can refer to form in either the syntactic or the morphological sense. CTM fails on each disambiguation, and the arguments for CTM immediately cease to be compelling once we register that ambiguity. The terms 'mechanical' and 'automatic' are comparably ambiguous. Once these ambiguities are exposed, it turns out that there is no possibility of mechanizing thought, even if we confine ourselves to domains where all problems can be settled through decision-procedures. The impossibility of mechanizing thought thus has nothing to do with recherché mathematical theorems, such as those proven by Gödel and Rosser. A related point is that CTM involves, and is guilty of reinforcing, a misunderstanding of the concept of an algorithm. (shrink)

Words change meaning over time. Some meaning shift is accompanied by a corresponding change in subject matter; some meaning shift is not. In this paper I argue that an account of linguistic meaning can accommodate the first kind of case, but that a theory of concepts is required to accommodate the second. Where there is stability of subject matter through linguistic change, it is concepts that provide the stability. The stability provided by concepts allows for genuine disagreement (...) and ameliorative change in the context of conceptual engineering. (shrink)

The theory of the organism-environment system starts with the proposition that in any functional sense organism and environment are inseparable and form only one unitary system. The organism cannot exist without the environment and the environment has descriptive properties only if it is connected to the organism. Although for practical purposes we do separate organism and environment, this common-sense starting point leads in psychological theory to problems which cannot be solved. Therefore, separation of organism and environment cannot be the basis (...) of any scientific explanation of human behavior. The theory leads to a reinterpretation of basic problems in many fields of inquiry and makes possible the definition of mental phenomena without their reduction either to neural or biological activity or to separate mental functions. According to the theory, mental activity is activity of the whole organism-environment system, and the traditional psychological concepts describe only different aspects of organisation of this system. Therefore, mental activity cannot be separated from the nervous system, but the nervous system is only one part of the organism­environment system. This problem will be dealt with in detail in the second part of the article. (shrink)

If a political theory of ownership is to be acceptable, it must rationally prescribe one system or model of ownership as opposed to others. Such a prescription would be rational only if strong normative arguments could be mounted to show it more desirable than its competitors. Thus, the prefatory work for such a theory would consist in the construction of viable models of ownership from which a sound choice could be made. This project would, however, be successful only if originating (...) from coherent, evaluatively neutral analyses of the concept of ownership and other related ideas. The point of this essay is to do this prefatory work. (shrink)

Julius Kovesi was a moral philosopher whose work rested on a theory of concepts and concept-formation, which he outlined in his 1967 book Moral Notions. But his contribution goes further than this. In sketching a theory of concepts and concept-formation, he was entering the philosophy of language. To make his account of moral concepts credible, he needs a broader story about how moral concepts compare with other sorts of concepts. Yet philosophy of language, once dominated (...) by Wittgenstein and Austin, came rather suddenly in the 1960s to be dominated by metaphysicians and philosophers of science trying to give an account of natural science concepts. How then does Kovesi’s theory of concepts fare when viewed in the light of this shift of interests? Does he have a theory of natural world concepts that can stand scrutiny? I will try to show that he does. To show this, I will focus on the concept of water. However, before doing this we need an outline of Kovesi’s account of what he called ‘notions formed about the inanimate world’. (shrink)

When an entity ontologically depends on another entity, the former ‘presupposes’ or ‘requires’ the latter in some metaphysical sense. This paper defends a novel view, Dependence Deflationism, according to which ontological dependence is what I call an aggregative cluster concept: a concept which can be understood, but not fully analysed, as a ‘weighted total’ of constructive and modal relations. The view has several benefits: it accounts for clear cases of ontological dependence as well as the source of disagreement in controversial (...) ones; it gives a nice story about the evidential relevance of modal, mereological and set-theoretic facts to ontological dependence; and it makes sense of debates over the relation's formal properties. One important upshot of the deflationary account is that questions of ontological dependence are generally less deep and less interesting than usually thought. (shrink)

This paper shows the ways in which Kant’s notions of the feeling of life and the feeling of the promotion of life may be influenced by Epicurus’ theory of pleasure and the Stoic notion of oikeiôsis, respectively. Accordingly, getting a clear picture of Epicurus’ theory of pleasure and the Stoic notion of oikeiôsis will help us (i) understand why Kant introduces these notions in the third Critique and (ii) why he identifies aesthetic pleasure with the feeling of the promotion of (...) life. As I will demonstrate, the feeling of life allows us to be conscious of the harmonious interaction of our faculties with each other while the feeling of the promotion of life allows us to be aware of the harmonious relationship between our faculties and nature. Hence, the feeling of the promotion of life indicates the well-being of the subject in its relation to its environment. (shrink)

By identifying the formal role of light in relativity theory with the formal role of text in Gadamer’s theory of hermeneutics, the two theories are brought into relationship. Through this fusion, the privileging of “space” in physics and the privileging of “time” in hermeneutics are reciprocally interrogated as horizons of truth.

This essay investigates the notion of simulation and the role it plays in Kourken Michaelian's simulation theory of memory. I argue that the notion is importantly ambiguous and that this ambiguity may threaten some of the central commitments of the theory. To illustrate that, I examine two different conceptions of simulation: a narrow one (simulation as replication) and a broad one (simulation as computational modeling), arguing that the preferred narrow conception is incompatible with the claim that remembering involves the simulation (...) of past episodes. Investigating possible solutions, I suggest that, despite some relatively serious consequences, the theory may be better off subscribing to the broad notion of simulation. (shrink)

We introduce the notions of syntactic synonymy and referential syn- onymy due to Moschovakis. Those notions are capable of accounting for fine- grained aspects of the meaning of linguistic expressions, by formalizing the Fregean distinction between sense and denotation. We integrate Moschovakis’s theory with the theory of concepts developed in the foundational ontology DOLCE, in order to enable a formal treatment of equivalence between concepts.

Two main theories of concepts have emerged in the recent psychological literature: the Prototype Theory (which considers concepts to be self-contained lists of features) and the Theory Theory (which conceives of them as being embedded within larger theoretical networks). Experiments supporting the first theory usually differ substantially from those supporting the second, which suggests that these the· ories may be operating at different levels of explanation and dealing with different entities. A convergence is proposed between the Theory (...) Theory and the intentional stance in the philosophy of language and mind. From this stance, concepts should not be thought of as concrete physical entities. (shrink)

There are numerous interpretations of Plato's theory of justice as it relates to the ideal state, deeply intertwined with his political philosophy. This complexity makes understanding his interlocking ideas challenging, as he seeks to construct a theory of the ideal state. Plato's philosophy of justice, particularly in its political dimension, emphasizes integration as a fundamental factor in grasping his theory. This paper aims to elucidate the original concept of justice in Plato's state by delving into the roots of the Republic, (...) analyzing its historical context. Plato's predictions reflect values and truths connected to politics and philosophy, emphasizing integration as essential to understanding his theory of justice, which lies at the core of his philosophy. This essay compares the relationship between the functions and class structure of the state. Plato classifies human nature into three components: reason, courage, and appetite, which correspond to three major classes in the state. The ruling class, educated in philosophy, governs the state. The military class, characterized by courage and strength, defends the state, while the professional class manages the everyday affairs of governance. Plato's theory posits functional specialization across all classes as fundamental to his ideal state. In essence, while Plato's imagined city may lack historical existence, it holds significant relevance in the realm of speculative human thought. Keywords: Justice. State. Function. Class. Rulers. Guardians. Producers. (shrink)

Dirac’s relativistic theory of electron generally results in two possible solutions, one with positive energy and other with negative energy. Although positive energy solutions accurately represented particles such as electrons, interpretation of negative energy solution became very much controversial in the last century. By assuming the vacuum to be completely filled with a sea of negative energy electrons, Dirac tried to avoid natural transition of electron from positive to negative energy state using Pauli’s exclusion principle. However, many scientists like Bohr (...) objected to the idea of sea of electrons as it indicates infinite density of charge and electric field and consequently infinite energy. In addition, till date, there is no experimental evidence of a particle whose total energy (kinetic plus rest) is negative. In an alternative approach, Feynman, in quantum field theory, proposed that particles with negative energy are actually positive energy particles running backwards in time. This was mathematically consistent since quantum mechanical energy operator contains time in denominator and the negative sign of energy can be absorbed in it. However, concept of negative time is logically inconsistent since in this case, effect happens before the cause. To avoid above contradictions, in this paper, we try to reformulate the Dirac’s theory of electron so that neither energy needs to be negative nor the time is required to be negative. Still, in this new formulation, two different possible solutions exist for particles and antiparticles (electrons and positrons). (shrink)

In this article, I expound and assess two theories of meaning in life informed by the indigenous sub-Saharan African philosophical tradition. According to one principle, a life is more meaningful, the more it promotes community with other human persons. According to the other principle, a life is more meaningful, the more it promotes vitality in oneself and others. I argue that, at least upon some refinement, both of these African conceptions of meaning merit global consideration from philosophers, but that (...) the vitality approach is more promising than the community one for capturing a wider array of intuitions about what confers meaning on a life. I further argue, however, that there are objections that apply with comparable force to both theories; neither one does a good job of entailing that and explaining why certain types of reason and progress can make a life more meaningful. Although these objections are characteristic of a ‘modern’ western outlook, I maintain that they are difficult for contemporary African philosophers to ignore and consider some ways they might respond to the objections.

In this paper, I present a general theory of topological explanations, and illustrate its fruitfulness by showing how it accounts for explanatory asymmetry. My argument is developed in three steps. In the first step, I show what it is for some topological property A to explain some physical or dynamical property B. Based on that, I derive three key criteria of successful topological explanations: a criterion concerning the facticity of topological explanations, i.e. what makes it true of a particular system; (...) a criterion for describing counterfactual dependencies in two explanatory modes, i.e. the vertical and the horizontal; and, finally, a third perspectival one that tells us when to use the vertical and when to use the horizontal mode. In the second step, I show how this general theory of topological explanations accounts for explanatory asymmetry in both the vertical and horizontal explanatory modes. Finally, in the third step, I argue that this theory is universally applicable across biological sciences, which helps to unify essential concepts of biological networks. (shrink)

This paper discusses the possibility of a metaphysical event theory that incorporates the concept of hope as a disposition. Hope is interp- reted as an expectation regarding future events while representing certain manifestations expected to occur in certain future events. In this sense, for ontologies that deny change or claim that its degree is purely fundamental, hope is a redundant concept in a metaphysical context. Additionally, in a world governed by fatalism or theological determinism it is meaningless to hope for (...) an alternative result. These two interpretations are compatible with a form of Stoicism as they depict a world where hope is redundant. To make hope more meaningful within the framework of event theory, we can propose an alternative view in which hope is considered not merely a psychological pheno- menon but also related and more active to metaphysical events. To strengthen this relation, we will change our perspective on our feature ontology and argue that what is hoped for can exist as a dispositional property that is realized as a particular consequence of an event, when it encounters certain stimuli. In examining the relationship between hope and event theory from different ontological perspectives, the first two view hope as a redundant concept for event theories. In contrast, the third perspective reinterprets hope as a disposition, making it more significant for a fundamental ontology. (shrink)

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)

This theory is an attempt to describe the universal phenomena like space, time, matter and energy as an inter-relationship bound by a newly discovered force named as the universal force. The universal force is shown to be the force of gravitation, electricity, magnetism, strong nuclear and weak nuclear forces. I believe any other force, hitherto fore not discovered; also, can be explained in terms of this universal force. Liberal use of wave-particle duality, relativity, quantum concepts is made to achieve (...) a harmonious and comprehensive synthesis of all the existing beliefs in physics into a new theory with some new concepts added here and there. While adding new concepts, enormous care has been taken to ensure that the existing beliefs are not contradicted. Moreover, the new concepts are proved to be correct theoretically by deriving the constants like G, σ, etc. (shrink)

A RELATIVISTIC THEORY OF PHENOMENOLOCICAL CONSTITUTION: A SELF-REFERENTIAL, TRANSCENDENTAL APPROACH TO CONCEPTUAL PATHOLOGY. (Vol. I: French; Vol. II: English) -/- Steven James Bartlett -/- Doctoral dissertation director: Paul Ricoeur, Université de Paris Other doctoral committee members: Jean Ladrière and Alphonse de Waehlens, Université Catholique de Louvain Defended publically at the Université Catholique de Louvain, January, 1971. -/- Universite de Paris X (France), 1971. 797pp. -/- The principal objective of the work is to construct an analytically precise methodology which can serve (...) to identify, eliminate, and avoid a certain widespread _conceptual fault_ or _misconstruction_, called a "projective misconstruction" or "projection" by the author. It is argued that this variety of error in our thinking (i) infects a great number of our everyday, scientific, and philosophical concepts, claims, and theories, (ii) has largely been undetected, and (iii), when remedied, leads to a less controversial and more rigorous elucidation of the transcendental preconditions of human knowledge than has traditionally been possible. The dissertation identifies, perhaps for the first time, a _projective_ variety of self-referential inconsistency, and proposes an innovative, self-reflexive approach to transcendental argument in a logical and phenomenological context. The strength of the approach lies, it is claimed, in the fact that a rejection of the approach is possible only on pain of self-referential inconsistency. The argument is developed in the following stages: A general introduction identifies the central theme of the work, defines the scope of applicability of the results reached, and sketches the direction of the studies that follow. The preliminary discussion culminates in a recognition of the need for a _critique of impure reason_. The body of the work is divided into two parts: Section I seeks to develop a methodology, on a purely formal basis, which is, on the one hand, capable of being used to study the transcendental foundations of the special sciences, including its own proper transcendental foundation. On the other hand, the methodology proposed is intended as a diagnostic and therapeutic tool for dealing with _projective_ uses of concepts. The approach initiates an analysis of concepts from a perspective which views _knowledge as coordination_. Section I describes formal structures that possess the status of preconditions in such a coordinative account of knowledge. Special attention is given to the preconditions of _identifying reference_ to logical particulars. The first section attempts, then, to provide a self-referential, transcendental methodology which is essentially revisionary in that it is motivated by a concern for conceptual error-elimination. Phenomenology, considered in its unique capacity as a self-referential, transcendental discipline, is of special relevance to the study. Section II accordingly examines a group of concepts which come into question in connection with the central theme of _phenomenological constitution_. The "_de-projective methodology_" developed in Section I is applied to these concepts that have a foundational importance in transcendental phenomenology. A translation is, in effect, proposed from the language of consciousness to a language in which preconditions of referring are investigated. The result achieved is the elimination of self-defeating, projective concepts from a rigorous, phenomenological study of the constitutive foundations of science. The dissertation was presented in a two volume, double-language format for the convenience of French and English researchers. Each volume contains an analytical index. (shrink)

The concept of inertial frame of reference in classical physics and special theory of relativity is analysed. It has been shown that this fundamental concept of physics is not clear enough. A definition of inertial frame of reference is proposed which expresses its key inherent property. The definition is operational and powerful. Many other properties of inertial frames follow from the definition, or it makes them plausible. In particular, the definition shows why physical laws obey space and time symmetries and (...) the principle of relativity, it resolves the problem of clock synchronization and the role of light in it, as well as the problem of the geometry of inertial frames.

The purpose of this paper is to describe how judges engage in constitutional design, irrespective of legal tradition. I examine in great detail the role of the judge: as a conflict solver, as a member of an institution, as part of the political system and as a human being, for those are factors that intervene in the activities he makes. I later analyze the dynamics that a Constitution can have: the change in their structure conceptualized as interpretation, mutation and resistance (...) and their relation. Interpretation is the determination of the scope of a norm, mutation is the change of meaning without amendment and resistance is a concept that bridges the first two, which is the capacity of the constitutional rule to adapt to the political game and to assume mutations. Finally, these concepts are intertwined in order to show how judges by means of their function, (re)design the Constitution by means of adjudication and policymaking (rule issuance by the stating of precedent).

The topic of this article is consciousness and, in it, I will theorize what consciousness is like and where it arises from. The work began to emerge and develop over time starting from my belief that consciousness is a physical self-referential phenomenon; thus, my attention was focused on the research for a self-referential process. I was confident that I could satisfy my curiosity through the reductionist method adopted by science. Unfortunately, neuroscientists and philosophers of mind realized that the attempts to (...) explain consciousness with this method have all proved inconclusive. For this reason, they are now trying to address the problem of consciousness with non-reductionist methods. As for me, I have always remained faithful to reductionism, but with the conviction that quantum mechanics, even though capable of making predictions with an extraordinary degree of accuracy, is a theory founded on wrong concepts. Thus, surprisingly, I have found a solution to the mystery of consciousness, perceiving a way to explain what it is like at its fundamental level in the field of quantum mechanics and, particularly, in one of its counterintuitive and generally less debated aspects among physicists today, but which aroused great interest in me: I am referring to the spin of the electron that will be described in this paper as a self-interacting process. This paper will also offer a rational explanation of the results obtainable in all experiments for measuring the spin of electrons through Stern-Gerlach magnets. In addition, my theory of consciousness is susceptible to experimental control. (shrink)

This paper analyzes the historical context and systematic importance of Kant's hypothetical use of reason. It does so by investigating the role of hypotheses in Kant's philosophy of science. We first situate Kant’s account of hypotheses in the context of eighteenth-century German philosophy of science, focusing on the works of Wolff, Meier, and Crusius. We contrast different conceptions of hypotheses of these authors and elucidate the different theories of probability informing them. We then adopt a more systematic perspective to (...) discuss Kant's idea that scientific hypotheses must articulate real possibilities. We argue that Kant's views on the intelligibility of scientific hypotheses constitute a valuable perspective on scientific understanding and the constraints it imposes on scientific rationality.

In a series of articles we try to show the need of a novel Theory for Theory of Computation based on considering time as a Fuzzy concept. Time is a central concept In Physics. First we were forced to consider some changes and modifications in the Theories of Physics. In the second step and throughout this article we show the positive Impact of this modification on Theory of Computation and Complexity Theory to rebuild it in a more successful and (...) fruitful approach. We call this novel Theory TC*. (shrink)

This author’s reply addresses critiques by Daniel Engster, Kelly Gawel, and Andrea Westlund about my 2020 book, Freedom to Care: Liberalism, Dependency Care, and Culture. I begin with a statement of my commitment to liberalism. In section two, I defend the value of a distinction between conceptions of persons in the real world and in contract theory to track inequalities in care when indexed to legitimate needs. I argue, as well, that my variety of contract theory supplies the normative content (...) needed to reject the subordination of women of color. Acknowledging the enduring danger of expressive subordination, I emphasize my theory’s compatibility with the full social inclusion of people with disabilities. Section three then defends liberal dependency care’s compatibility with radical critique and transformative change by emphasizing the abstract nature of its core theoretical module. Finally, in section four, I reaffirm conceptual distinctions between autonomy skills, care skills, and a sense of justice by explicating their theoretical roles. In that section, I also embrace Westlund’s insight that theorists of justice need to have skills enabling responsiveness to other perspectives. To this new requirement for actual theorists of justice, I further add that we must attain capacities to engage critically with our society’s norms. Thus, the final section of this article supplements the justificatory module of liberal dependency care, building from the necessary conditions specified as two-level contract theory toward an account of necessary and sufficient conditions for this liberalism’s justificatory module.
