Does there exist any equivalence between the notions of inconsistency and consequence in paraconsistent logics as is present in the classical two valued logic? This is the key issue of this paper. Starting with a language where negation ( ${\neg}$ ) is the only connective, two sets of axioms for consequence and inconsistency of paraconsistent logics are presented. During this study two points have come out. The first one is that the notion of inconsistency of paraconsistent logics turns out to (...) be a formula-dependent notion and the second one is that the characterization (i.e. equivalence) appears to be pertinent to a class of paraconsistent logics which have double negation property.

This book introduces the theory of graded consequence and its mathematical formulation. It also compares the notion of graded consequence with other notions of consequence in fuzzy logics, and discusses possible applications of the theory in approximate reasoning and decision-support systems. One of the main points where this book emphasizes on is that GCT maintains the distinction between the three different levels of languages of a logic, namely object language, metalanguage and metametalanguage, and thus avoids the problem of violation of (...) the principle of use and mention; it also shows, gathering evidences from existing fuzzy logics, that the problem of category mistake may arise as a result of not maintaining distinction between levels.

Venn diagram system has been extended by introducing names of individuals and their absence. Absence gives a kind of negation of singular propositions. We have offered here a non-classical interpretation of this negation. Soundness and completeness of the present diagram system have been established with respect to this interpretation.

In this paper, we study two companions of a logic, viz., the left variable inclusion companion and the restricted rules companion, their nature and interrelations, especially in connection with paraconsistency. A sufficient condition for the two companions to coincide has also been proved. Two new logical systems—intuitionistic paraconsistent weak Kleene logic (IPWK) and paraconsistent pre-rough logic (PPRL)—are presented here as examples of logics of left variable inclusion. IPWK is the left variable inclusion companion of intuitionistic propositional logic and is also (...) the restricted rules companion of it. PPRL, on the other hand, is the left variable inclusion companion of pre-rough logic but differs from the restricted rules companion of it. We have discussed algebraic semantics for these logics in terms of Płonka sums. This amounts to introducing a contaminating truth value, intended to denote a state of indeterminacy. (shrink)

A new diagram system \ where properties are fundamental and an object exists only w.r.t a property is presented. This work modifies both in syntax and semantics the system \ proposed by Choudhury and Chakraborty to picturise and address issues connected with open universe. Semantics for the current system is given. Soundness and completeness w.r.t the semantics are established.

A detailed study of graded frame, graded fuzzy topological system and fuzzy topological space with graded inclusion is already done in our earlier paper. The notions of graded fuzzy topological sys...

Two types of logical consequence are compared: one, with respect to matrix and designated elements and the other with respect to ordering in a suitable algebraic structure. Particular emphasis is laid on algebraic structures in which there is no top-element relative to the ordering. The significance of this special condition is discussed. Sequent calculi for a number of such structures are developed. As a consequence it is re-established that the notion of truth as such, not to speak of tautologies, is (...) inessential in order to define validity of an argument. (shrink)

This paper contains two traditions of diagrammatic studies namely one, the Euler–Venn–Peirce diagram and the other, following tradition of Aristotle, the square of oppositions. We put together both the traditions to study representations of singular propositions, their negations and the inter relationship between the two. Along with classical negation we have incorporated negation of another kind viz. absence. We have also considered the changes that take place in the context of open universe.

The present book discusses all aspects of paraconsistent logic, including the latest findings, and its various systems. It includes papers by leading international researchers, which address the subject in many different ways: development of abstract paraconsistent systems and new theorems about them; studies of the connections between these systems and other non-classical logics, such as non-monotonic, many-valued, relevant, paracomplete and fuzzy logics; philosophical interpretations of these constructions; and applications to other sciences, in particular quantum physics and mathematics. Reasoning with contradictions (...) is the challenge of paraconsistent logic. The book will be of interest to graduate students and researchers working in mathematical logic, computer science, philosophical logic, linguistics and physics. (shrink)

In this paper, we study some classes of logical structures from the universal logic standpoint, viz., those of the Tarski- and the Lindenbaum-types. The characterization theorems for the Tarski- and two of the four different Lindenbaum-type logical structures have been proved as well. The separations between the five classes of logical structures, viz., the four Lindenbaum-types and the Tarski-type have been established via examples. Finally, we study the logical structures that are of both Tarski- and a Lindenbaum-type, show their separations, (...) and end with characterization, adequacy, minimality, and representation theorems for one of the Tarski–Lindenbaum-type logical structures.

IntroductionThis paper focuses on a radical feminist engagement with mathematical pluralism. Radical Feminists are interested in a project of methodological re-tooling. Mathematical pluralism appears to be a possible source of help in this direction.Materials and MethodsWith this aim in view the article examines the contributions of Mihir Chakraborty and Amita Chatterjee. By using the method of philosophical argument their theses have been judged from a feminist perspective.ResultsSome very interesing results have been arrived at in terms of accommodating vagueness (...) and pluralism into feminist methodology by the help of mathematical pluralism.DiscussionBy the way of an ongoing discussion the paper states the contours of a radical feminist road map and specifies the kind help they seek from mathematical pluralism.

About this book Hilary Whitehall Putnam was one of the leading philosophers of the second half of the 20th century. As student of Rudolph Carnap's and Hans Reichenbach's, he went on to become not only a major figure in North American analytic philosophy, who made significant contributions to the philosophy of mind, language, mathematics, and physics but also to the disciplines of logic, number theory, and computer science. He passed away on March 13, 2016. The present volume is a memorial (...) to his extraordinary intellectual contributions, honoring his contributions as a philosopher, a thinker, and a public intellectual. It features essays by an international team of leading philosophers, covering all aspects of Hilary Putnam's philosophy from his work in ethics and the history of philosophy to his contributions to the philosophy of science, logic, and mathematics. Each essay is an original contribution. -/- Author information James Conant, Univ. of Chicago/Univ. of Leipzig, USA/Germany; Sanjit Chakraborty, IISER Kolkata/VIT-AP University, India. (shrink)

The nominal ground that entwines human beings and animal behaviours is unwilling to admit moral valuing as a non-human act. Just to nail it down explicitly, two clauses ramify the moral conscience of human beings as follows: a) Can non-humans be moral beings?, b) Unconscious animal behaviours go beyond any moral judgments. My approach aims to rebuff these anthropomorphic clauses by justifying animals’ moral beings and animals’ moral behaviours from a meta-ethical stance. A meta-ethical outlook may enable an analysis of (...) ethical and normative views through the limit of moral motives and reasoning. Animals’ sense of moral motives and their apparatus of getting involved in moral acts cannot be compared with human actions. In human moral engagement, we abide by moral paradigmatic theories and their diversified attitudes that could have conceptual and linguistic use in our societal discourses. However, animals’ intentional apparatus may have the propensity to choose an act following the moral consequences (care, utility, responsibility, etc.) in their life-forms. (shrink)

This fictionalized script traces the contours of the conversation that seeks to fathom the crisis unleashed by the outbreak and global spread of the coronavirus and the ensuing anxieties created in our current social living. The scenario of deepened isolation of the self from the other is considered, and it is proposed that isolation, while an unavoidable requirement, does not mean it is some mental lassitude but rather may be seen as an enthusiastic concern toward recovering physical and mental wellbeing (...) of the larger communities concerned to control the possible avenues of transmission of the contagion. The conversation meanders around the issue of quarantine, its attraction or otherwise, and who benefits from this restriction, its effects on one’s mental constitution, etc. Philosophers have been known to isolate themselves in other contexts and situations give us a taste of what is to come in the dialogue to resist the calamity of the coronavirus and its grim effects that engulf the entire humanity.

Uniformity in human actions and attitudes incumbent with the ceteris paribus clause of folk psychology lucidly transits moral thoughts into the domain of subject versus object-centric explorations. In Zettel, Wittgenstein argues, “Concepts with fixed limits would demand uniformity of behaviour, but where I am certain, someone else is uncertain. And that is the fact of nature.” (Wittgenstein 2007, 68). Reflecting on the moral principle of “ethical giving” revives a novel stance in modern moral philosophy. An “ethical giving” is a moral (...) position that looks at giving from the context of harmonizing the changing demands of situations with normative ethical principles. Despite giving more prominence to the query of intuition, the chapter brings up the justification of normative moral principles pertaining to their applications and purports. Human activities aimed at decision-making goals conducted by the moral compass are nothing but the sanction of certain ethical norms and rules. In this context, two principles, the normative aspect and the perspective aspect need to be expounded in parallel. (shrink)

Amartya Sen’s remarkable endeavour to realize the normative capability of welfare economics goes beyond the impecunious resultants of the neoclassical welfare economy. The neoclassical welfare economy decoratively bracketed values to speculate about factual observations. This was due to the influence of logical positivists and their convictions about experimental scientific statements (primarily mathematical) and their vicinity to empirical truths and analytic statements. Sen adequately inquires “whether morality can be expressed in the form of choice between preference patterns rather than between actions” (...) (Sen, 1997a, 78). “A new phase classical theory” in economics from the hands of Sen and some others put forth two pivotal issues in a unified manner: a. Mathematical models of an economy. b. Ethical reflection on the subject of welfare economy–a value-laden enterprise in Sen’s literature. -/- In general, welfarists and utilitarians affirm that moral values are anchored in individual agency and involve mental metric utilities (pleasure, happiness, pain etc.). This focus, first of all, results in a disadvantage, as it undermines freedom in terms of achievement. Secondly, it pays no heed to achievement reasonably giving more importance to those who are incapable of reflecting on any one of those mental metrics. Besides, Sen argues that equality of opportunity does not accord with the equality of freedom, and its reason is rooted in the scope of the incongruity of human beings and the diversified meanings of efficiency. Developing a general methodological approach to revisit the notion of inequality concerned by exploring a particular substantive stand that Sen aims to underscore involves examining how social arrangements work to define freedom, capabilities, and welfare to ensure comparisons and assessments of quality of life.

Simon Blackburn, in Truth A Guide for the Perplexed (Blackburn 2006), deploys the relation of thought with the facts and says, ‘We met the argument that theorizing involves an impossible activity of stepping outside our own skins and pretending to a ‘transcendental’ point of view, a standpoint from which we can survey the relationship between our thoughts and facts, without using the very forms of thought whose relation to the facts we are hoping to describe.’ (Blackburn, 2006, 109). My philosophical (...) reflections on this claim appreciate the view and turn towards the epistemic semblance in the metaphysical purview. A few challenges of the theory take up a side-effect of the ‘knowing procedures’ and its subsequent notion of the rigid concomitance of realism without a human face. My endeavor would be to slightly bypass the account of objective realism and debut into the sphere of the old-fashioned query, ‘what do we know about the conceptualized world where concepts steadily contaminate objects?’ We may appreciative beliefs and concepts, which are human creations, as these impart to the human-experienced world where concepts are the objective features of the subject’s conceptual scheme.

This book deals with the intricate issue of approaching atheism—methodologically as well as conceptually—from the perspective of cultural pluralism. What does ‘atheism’ mean in different cultural contexts? Can this term be applied appropriately to different religious discourses which conceptualize God/gods/Goddess/goddesses (and also godlessness) in hugely divergent ways? Is my ‘God’ the same as yours? If not, then how can your atheism be the same as mine? In other words, this volume raises the question: Is it not high time that we (...) proposed a comparative study of atheism(s) alongside that of religions, rather than believing that atheism is centered in the ‘Western’ experience? Apart from answering these questions, the book highlights the much-needed focus on the philosophical negotiations between atheism, theism and agnosticism. The fine chapters collected here present pluralist negotiations with the notion of atheism and its ethical, theological, literary and scientific corollaries. (shrink)

This paper attempts to revisit how ‘acquaintance’ could bring about belief and how belief becomes knowledge in our language system due to the credential undertaking of truth, justification, evidence, and causal or conceptual preservation. My quest in this paper is to interrogate belief and the cessation of belief (I call this the ‘death of belief’) from the perspective of the doxastic approach of externalism and internalism in the philosophy of language and philosophy of mind. I will attempt to make sense (...) of the nominal appeal (an approach that conserves the process of continuing belief through evidence and conceptualization) to both of these ideas in a sophisticated manner. The linguistic form of using words seems allied to the context sensitivity of the speakers involved in social practices. A tripartite structure pivots the model of linguistic belief, where minds are causally entrenched in a world that stimulates conceptual or internal states, representing how objectivity works. The entanglements of concepts with pictures hinge on conceptual prerequisites to impact the world. (shrink)

A collective understanding that traces a debate between ‘what is science?’ and ‘what is a science about?’ has an extraction to the notion of scientific knowledge. The debate undertakes the pursuit of science that hardly extravagance the dogma of pseudo-science. Scientific conjectures invoke science as an intellectual activity poured by experiences and repetition of the objects that look independent of any idealist views (believes in the consensus of mind-dependence reality). The realistic machinery employs in an empiricist exposition of the objective (...) phenomenon by synchronizing the general method to make observational predictions that cover all the phenomena of the particular entity without any exception. The formation of science encloses several epistemological purviews and a succession of conjectures cum refutation that a newer theorem could reinstate. My attempt is to advocate a holistic plea of scientific conjectures that outruns the restricted regulation of experience or testable hypothesis to render the validity of a chain of logical reasoning (deductive or inductive) of basic scientific statements. The milieu of scientific intensification integrates speculation that loads efficiency towards a new experimental dimension where the reality is not itself objective or observers relative; in fact the observed phenomenon divulges in the constructive progression of preferred methods of falsifiability and uncertainty.

This thematic volume entitled Human Minds and Cultures deciphers different aspects of human minds and cultures that differ in their methodological patterns. It exhibits humanity as a universal, underlying cultural multiplicity coping with diverse prospects of normative morality, semiotics, and socio-linguistic human affairs.

Human activities aimed at decision-making goals conducted by the moral compass are nothing but the sanction of certain ethical norms and rules. In this context, two principles, the normative aspect and the perspective aspect need to be expounded in parallel. The perspective-based principle seeks practical guides to action, whereas the normative aspect principle looks for the concrete moral justification behind it. Normatively based moral decisions hinge on the probabilities and interests of agents that can sometimes lead towards a better choice. Thomas Nagel’s thought sounds more appealing, since his idea of practical conflict bends towards “...conflict between values which are incomparable for reasons apart from uncertainty about the facts.” (Nagel 2013, 128). Positions on moral personality and equality of justice collide with the conception of verities of the agents’ reason that cogitate a minimal aspect on the morally significant properties (range properties), which can hardly be possessed by all human beings equally. This argument sounds reasonable in light of Singer’s thought of “the principle of equal consideration of interests.” (Singer 2003, 21–22) The concern of this section is deliberative about how an agent could balance the demand of moral situations and the spirit of the moral principle devoid of being close to the relative truth. The conception of the moral decision remains capricious in line with the agent’s mood, time, and situation. The germane queries are: (a) How could one get the simpliciter of moral balance in “ethical giving” or offering help to the poor, orphans, and so on, who need helps from the agents and society? (b) Can we find any universalized principle in defense of ethical giving? (shrink)

Darshana, in the sense of true philosophical knowledge, Darshana is first quoted in the Vaiśesika Sūtra (first century CE) to mean the perfect vision of everything. Etymologically, Darshana evolves from the Sanskr̥ti term Drś, that is, vision. The contemporary use of the term Darshana finds its new dimension in the writings of Haribhardra (eighteenth century CE), who considers different philosophical schools in the cord of Darshana in his text Ṣad-darśana-samuccaya. Later, eminent Vedāntin Mādhava in fourteenth century CE popularized and expatiated (...) the meaning of Darshana in Sarvadarśana Saṅgraha. The purport of the term Darshana is embedded in the notion of Indianness that caters to an influential uniqueness in Hinduism, Jainism (Samyak Darshana or liberation consists in right vision) and Mahayana Buddhism (Nagarjuna’s dictum tattva-darśana, i.e., the true reality, and Vasubandhu’s use of Darshana marga, i.e., the conduit of seeing). -/- The conception of the word guru in Indian cultures goes back to the Upanishadic era, especially in the Mundakopanishad, where Brahma (the creator of the world) taught the Brahma Vidya (the foundation of all knowledge or the speculative discussion about ultimate reality) to his eldest son, Atharvan. Later, Artharvan transmitted the Brahma Vidya to Angiras, who shared the absolute knowledge with Satyavaha, a successor of Sage Bharadwaja. Satyavaha narrated to Bharadwaja, who finally imparted the knowledge (both the higher and lower levels) to Angiras. One could find a significance herein using the Upanishadic term paraparam (Mundakopanishad, 1.2). The term not only indicates that the foundation of all knowledge has two different folds – para (transcendent) and apar (mundane) – but also that the term paraparam tinges on the transmission progression of the knowledge from guru (enlightened master) to his shisya (dedicated disciple). The proper way of learning Brahma Vidya depends on the gurupasadana; the only guru can condescend to expose wisdom to the devoted disciples. (shrink)

This book puts forward a harmonious analysis of similarities and differences between two concepts—human minds and cultures—and strives for a multicultural spectrum of philosophical explorations that could assist them in pondering the striking pursuit of envisaging human minds and cultures as an essential appraisal of philosophy and the social sciences. The book hinges on a theoretical understanding of the indispensable liaison between the dichotomy of minds and objectivity residing in semantic-ontological conjectures. -/- The ethnographic sense of cultures confines the scope (...) of cultural scientism, an evolutionary paradigm on the functionalist turn, where one could enthral the cultural phenomenon from the contentment of the conflict of scientific quandaries. Hence, cultural relativism concedes that cultures have some descriptive contents, like customs, beliefs, moral codes, other minds, etc., that are followed by an individual or a group of people. However, the notion of societal semiotics embarks on the ‘semiotic conception of culture’ that deploys modernity and values centred on ethical conjectures. -/- Human Minds and Cultures conspicuously attune the cultural edifice of moral minds and cope with the enduring prospects of ethics, genders, laws, and socio-political affairs. Essential reading for anyone with a sparkling interest in human minds and cultures. (shrink)

Hilary Putnam was one of the truly great philosophers of the twentieth century. In a memorial essay I published elsewhere, I wrote: Leading philosophy towards constant dynamic expeditions and holding on to an incredible style of self-critique, Hilary Putnam (1926–2016), over five decades, has been in the process of making laudable contributions to philosophy and philosophy of science by being a beacon to a series of philosophical generations. He was a profound scholar full of wisdom, morality, and love of humanity, (...) in a word a “Philosopher’s Philosopher.”1 Hilary Putnam, whom I called “Gurudev” (mentor), was a renaissance man of philosophy for his laudable and novel contribution in the fields of philosophy and philosophy of science. The impetus for bringing out this honorary volume on his fundamental contributions to philosophy and philosophy of science began after his peaceful death on March 13, 2016 in Arlington, Massachusetts.

Immanuel Kant, with his “brilliantly dry style” (Schopenhauer), expounds the notable theory that “objects are approaching to the mind” via the spectacle metaphor by addressing transcendental idealism in support of the mind as an active knower (mind-making nature), not passive in a realistic sense, while objects of knowledge conform to the mind begotten in categories of understanding. On Kant’s view, James Conant writes, “Kant’s term for this unity, considered at this level of abstraction, is the original synthetic unity of the (...) understanding. This admits of forms of further determination, one sensible and one intellectual. This form of unity – categorial unity – characterizes both the manner in which objects are given to us in intuition and the manner in which concepts are combined in judgments” (Conant 2016: 114). -/- Insofar the same pioneering stance is reflected in the Groundwork of Metaphysics of Morals (Kant 1972) and the Critique of Practical Reason (Kant 1996), where Kant underscores the accessible account of reason and freedom as the content of fundamental moral principle toward a kind of universalizable moral duty attuned with the formulation of categorical imperative. The justification and groundwork of these moral laws cannot be liaison in sensory experience but on pure reason, which Kant calls “a priori,” a conviction stems from the understanding of rational necessitation of moral obligation and free autonomous agency. This interpretation absorbs the practical principle that underlies the subjective maxim to justify the necessary and sufficient conditions for a universal moral law. Kant starts out saying that an act is morally right if it is performed for the sake of broadening the vista of maxim infused by goodwill consisting of the categorical imperative that sounds an exceptionless command, abstract law, and universally applicable normative principle as well. For Kant, the categorical imperative has many-sided structures: a. Ethical requirements are rational requirements of the moral agent. b. The rational requirement goes toward universal laws. c. These moral requirements must be followed by equality, freedom, and goodwill. (shrink)

There is a long history to the debate of nationalism. The Indian nationalism has emerged after a long people’s movement the truth to which is often denied by a range of forces who have ideological leanings towards the ideology of Hindutwa. This paper is an attempt to revisit the historical context in which Indian nationalism has emerged and evaluate it in reference to the contemporary time. It emphasizes on the relation between the nation and the state with special reference to (...) its impact on the universities. Further, the paper suggests that in order to uphold the idea of university and nation, an inclusive and secular idea of nation has to be espoused. Lastly, it suggests that a university needs to foster a non sectarian approach and broaden its vision for an internationalist outlook. (shrink)

This chapter critiques the notion of identity, a philosophical reaction in the Quinean sense that vindicates another significant hypothesis, which is called the “No entity without identity” theorem. Here, the identification of an entity relies upon its identity. The first segment of this chapter revisits the following question: How do we encounter the concept of a subjective “mind”? Could we “infer” or “experience” the concept of “mind” in our daily lives? Every entity has some characteristics that prompt comparison with similar (...) entities. Although I think that other minds have a subjective periphery and that other minds have an objective periphery lurking behind this (privileged access), we can construe the relationship in a subjective way (individual mind). In the second section of the chapter, I address a different point by considering why the idea of “other minds” causes philosophical dilemmas. Can “other minds” exist as a substance in one’s own mind? The category of human knowledge encompasses the reality of minds and other minds. The other minds remain an accompanying part of the individual mind since the expression, belief, and mental content of the individual mind merge in the linguistic expression in a split manner that we may ascribe as privileged access (subjective incorrigible knowledge) and corrigible knowledge. But I think that the relation between minds and other minds sounds especially idiosyncratic in its own identity. Despite becoming diverse, the individual mind can still be intimate by blending and attunement between the subjective and objective dichotomy. (shrink)

In Indian philosophy, Bhāṭṭa Mīmāṃsakas and Advaita Vedāntins recognize abhāva or anupalabdhi (non-apprehension) as an independent source of knowledge; but no other school of Indian philosophy agrees with them on this issue, and for that reason, arguments have been given by the latter schools for rejecting anupalabdhi as an independent means of knowledge. In this paper, I am going to evaluate only those arguments which have been given by the Vaiśeṣika thinkers, who admit only two pramāṇa-s, viz. pratyakṣa and anumāna, (...) and reject anupalabdhi as an independent pramāṇa. There have been many scholarly studies dealing with the arguments against the reduction of non-apprehension to some other source of knowledge that have been offered by the Bhāṭṭa Mīmāṃsā and Advaita Vedānta, but there is hardly any full-length work that deals with the Vaiśeṣika’s reduction of non-apprehension to some other source of knowledge. In the present paper, an attempt has been made at providing a clear and specific account of the same. (shrink)

Electronegativity is an important physico-chemical concept to study the chemical structure and reactivity. Although, the conundrum related to measurement of electronegativity still persists. In view of this fact, a simple yet rigorous scale of electronegativity, invoking an inverse relationship with atomic nucleophilicity index, has been proposed for 103 elements of the periodic table. The computed data follows periodicity distinctly satisfying all the sine qua non of a standard scale of electronegativity. Further, electronegativity values display a sound similarity with the standard (...) electronegativity scales validating the suitability of the proposed model. Molecular electronegativities of some polyatomic molecules have also been calculated using the proposed scale of electronegativity.Graphic. (shrink)

This special issue of Sophia, titled Living without God: A Multicultural Spectrum of Atheism, deals with the intricate issue of approaching atheism—methodologically as well as conceptually—from the perspective of cultural pluralism. What does ‘atheism’ mean in different cultural contexts? Can this term be applied appropriately to different religious discourses which conceptualize God/gods/Goddess/goddesses in hugely divergent ways? Or would that rather be a sort of hegemonic homogenization of all possible modalities of living without God, as Jessica Frazier argues? Is my ‘God’ (...) the same as yours? If not, then how can your atheism be the same as mine? In other words, this issue of Sophia raises the question: Is it not high time that we proposed a comparative study of atheism alongside that of religions, rather than believing that atheism is centered in the ‘Western’ experience? Besides, how can we explore the modalities of atheist religiosity such as we find in Buddhism and Jainism and also, arguably, in certain forms of Hinduism, as far as the Indic traditions are concerned? How might these negotiations of atheism across the multicultural spectrum interrogate our tendency to place atheism within the context of the binary opposition of science and religion? Besides, there is a need to focus on the philosophical negotiations between atheism, theism and agnosticism and the discourses that emerge from such dialogues, including that of postsecularity.

Scientific realism does not view theoretical terms as mere instruments of experimental predictions; it grants referential status to natural kind terms with 'epistemic access' and view scientific theories and terms as corresponding to physical phenomena and entities which exist independently of observation, and as thereby being the source of objective -approximate and not absolute- knowledge of the physical realm. As a result, scientific realism is accused of ontologising the unobservables. Against this charge, scientific realism posits the idea of the dialectical (...) relation between theoretical terms referring to the unobservables and scientific methods. The second argument made by realism is the ‘no miracle’ thesis. These arguments stand challenged by the Copenhagen interpretation of quantum mechanics. The aim of the paper is to examine the relevance of the two arguments of scientific realism in countering the idea that the existence of quantum states in the microphysical world renders realism obsolete.

The COVID-19 pandemic has presented a significant challenge to countries worldwide, and South Asia has not been an exception. The region is home to over 1.8 billion people and some of the world's largest cities, making it a potential hotspot for the virus's spread. This paper presents case studies from three South Asian countries: India, Sri Lanka, and Pakistan, analyzing their response to the pandemic and the measures taken to contain its spread. The paper analyzes India, Pakistan, and Sri Lanka's (...) healthcare infrastructures, their strengths and weaknesses, and the measures taken by these governments to mitigate the impact of the pandemic on the economy and society. Overall, the paper provides insights into the response to the pandemic in South Asia, highlighting the successes and challenges faced by the countries analyzed. The case studies offer valuable lessons on the importance of preparedness, effective communication, and coordinated responses to pandemics. They also underscore the need for greater investment in healthcare infrastructure and the importance of addressing socioeconomic disparities to effectively combat pandemics in the region. This paper also brings together the recent publications on the current pandemic to help understand the recent works in this area. (shrink)
