As British and American idealism waned, new realisms displaced them. The common background of these new realisms emphasized the problem of the external world and the mind-body problem, as bequeathed by Reid, Hamilton, and Mill. During this same period, academics on both sides of the Atlantic recognized that the natural sciences were making great strides. Responses varied. In the United States, philosophical response focused particularly on functional psychology and Darwinian adaptedness. This article examines differing versions of that response in William (...) James and Roy Wood Sellars. James viewed the mind as a “fighter for ends.” His neutral monism, by taming the mind-body problem and the problem of the external world, provided a secure metaphysics of mind as functional activity. In contrast, Sellars ’s scientific realism endorsed physical reality but was not mechanistic or reductionist. His critical realism and evolutionary naturalism offered novel metaphysical and epistemological positions in comparison with other American and British realisms. James and Sellars are distinguished from British philosophy in 1890–1918 in the types of realism they endorsed and in their success at introducing Darwinian evolutionary considerations and functional psychology into mainstream philosophy.

One hundred years ago, Roy Wood Sellars' "Evolutionary Naturalism" (1922) was published, a somewhat forgotten milestone in the development of a non-reductionist naturalism. Sellars did not yet speak of emergence but of "novelty", but saw the importance of systemic properties. He underestimated Darwin and the importance of studying animal behaviour, so some of his insights seem outdated. On the other hand, he was ahead of his time with ideas that are still valuable today. He therefore deserves a place (...) in the development of evolutionary naturalism and in the history of philosophy in general. (shrink)

Although commonly cited as one of the philosophers responsible for the resurgence of interest in pragmatism, Wilfrid Sellars was also the son of Roy Wood Sellars, one of the most dedicated critical realists of the early 20th century. Given his father’s realism and his own ‘scientific realism,’ one might assume that the history of realism – and, despite contemporary interest, not pragmatism – would best serve as the historical background for Wilfrid Sellars’ philosophy. I argue that Wilfrid (...) Sellars, far from being the adherent to classical pragmatism assumed by some, holds more in common with critical realism - specifically, a realism that was framed in opposition to pragmatism – than one finds amongst the writings of Charles Sanders Peirce, William James, or John Dewey. I support this claim by examining Wilfrid Sellars’ adoption of his father’s criticisms of C.I. Lewis, and offer various arguments and historical considerations against thematic accounts that insist on a strong connection between Wilfrid Sellars and pragmatism. (shrink)

The “Morbid Fear of the Subjective” (copyright by Roy Wood Sellars) represents a key-element of the American naturalist debate of the Mid-twentieth century. On the one hand, we are witnessing to the unconditional trust in the objectivity of scientific discourse, while on the other (and as a consequence) there is the attempt to exorcise the myth of the “subjective” and of its metaphysical privateness. This theoretical roadmap quickly assumed the shape of an even sociological contrast between the “democraticity” of (...) natural sciences and the fanaticism implicit in supernatural metaphysical systems. In between these two extremes stood phenomenology, in its early days on American soil. Its notion of “evidence”, which is less easily to naturalize than it might seem, was in fact hardly consistent with the widespread concept of “natural experience” of the world. (shrink)

Behaviorism was a peculiarly American phenomenon. As a school of psychology it was founded by John B. Watson (1878-1958) and grew into the neobehaviorisms of the 1920s, 30s and 40s. Philosophers were involved from the start, prefiguring the movement and endeavoring to define or redefine its tenets. Behaviorism expressed the naturalistic bent in American thought, which came in response to the prevailing philosophical idealism and was inspired by developments in natural science itself. There were several versions of naturalism in American (...) philosophy, and also several behaviorisms. Most behaviorists paid homage to Darwinian functionalism; all forswore introspection and made learned changes in behavior the primary subject matter and explanatory domain of psychology. They differed in their descriptions of behavior, modes of explanation, and attitudes toward mentalistic concepts. Watson was a strict materialist who wanted to eliminate all mentalistic talk from psychology. Edward Chace Tolman (1886-1959) regarded mind as a biological function of the organism. He permitted mentalistic terms such as 'purpose' in behavioral description, and posited intervening processes that included 'representations' of the environment, while requiring such processes be studied only as expressed in behavior. Clark L. Hull (1884-1952) developed a hypothetical-deductive version of behaviorism, akin to Tolman's functionalism in positing intervening variables but without his cognitivist constructs. B. F. Skinner (1904-90) rejected intervening variables and developed his own account of the behavior of the whole organism, based on the laws of operant conditioning. The naturalism in American philosophy of the early twentieth century showed respect for the natural sciences, especially biology and psychology. John Dewey (1896, 1911), George Santayana (1905, 1920), and F. J. E. Woodbridge (1909, 1913) expressed this attitude. It animated the neorealism of E. B. Holt and Ralph Barton Perry, who gave special attention to psychology, and the evolutionary naturalism and critical realism of Roy Wood Sellars. This naturalism differed from Watson's in regarding mind as part of nature from a Darwinian and functionalist perspective, and treating behavior as the product of the mental functioning. It fed Tolman's version of behaviorism. It was not materialistic or physical-reductionist. Only later, with Quine and logical empiricism, was behaviorism seen as essentially physicalistic. (shrink)

This paper reconstructs the function argument of Aristotle’s Eudemian Ethics 2.1. The argument seeks to define happiness through the method of division; shows that the highest good is better than all four of the goods of the soul, not only two, as commentators have thought; and unlike the Nicomachean argument, makes the highest good definitionally independent of the human function.

Immanuel Kant promised, ‘as Your Majesty's loyal subject’, to abstain from all public lectures about religion. All past commentators agree this phrase permitted Kant to return to the topic after the King died. But it is not part of the ‘at-issue content’. Consequently, ‘as Your Majesty's loyal subject’ is no more an escape clause than the corresponding phrase in ‘I guarantee, as your devoted fan, that these guitar strings will not break’. Just as the guarantee stands regardless of whether the (...) guarantor ceases to be your devoted fan, the compliance conditions of Kant's promise are not affected by Kant's ceasing to be the king's loyal subject. For good or ill, Kant made a lying promise to King Friedrich Wilhelm II in 1794. (shrink)

We study shared intentions in what we call “loose groups”. These are groups that lack a codified organizational structure, and where the communication channels between group members are either unreliable or not completely open. We start by formulating two desiderata for shared intentions in such groups. We then argue that no existing account meets these two desiderata, because they assume either too strong or too weak an epistemic condition, that is, a condition on what the group members know and believe (...) about what the others intend, know, and believe. We propose an alternative, pooled knowledge, and argue that it allows formulating conditions on shared intentions that meet the two desiderata. (shrink)

Seventy-seven years have elapsed since the Sylhet referendum (July 6 & 7, 1947). The part of Sylhet that was scissored during the partition and the Bengalis who came from the other side are still carrying the deep wound of the curse of that partition, compromising with the marginalization. Moreover, the Bengalis of the state are facing a special identity crisis as a result of the nationwide skepticism about the status of Bengalis in Assam. Following the Sylhet referendum, the curse of (...) the Sylhet bifurcation, that is, the second partition of Sylhet is still haunting them. The article attempts to illustrate a chronological analysis of the context and consequences of this century-long language tussle leading to persistent racial conflict and the other consequences relating to identity and citizenship.

According to Essentialism, an object’s properties divide into those that are essential and those that are accidental. While being human is commonly thought to be essential to Socrates, being a philosopher plausibly is not. We can motivate the distinction by appealing—as we just did—to examples. However, it is not obvious how best to characterize the notion of essential property, nor is it easy to give conclusive arguments for the essentiality of a given property. In this paper, I elaborate on these (...) issues and explore the way in which essential properties behave in relation to other related properties, like sufficient-for-existence properties and individual essences.

The paper compares the suitability of two different epistemologies of counterfactuals—(EC) and (W)—to elucidate modal knowledge. I argue that, while both of them explain the data on our knowledge of counterfactuals, only (W)—Williamson’s epistemology—is compatible with all counterpossibles being true. This is something on which Williamson’s counterfactual-based account of modal knowledge relies. A first problem is, therefore, that, in the absence of further, disambiguating data, Williamson’s choice of (W) is objectionably biased. A second, deeper problem is that (W) cannot satisfactorily (...) elucidate modal knowledge. Third, from a naturalistic perspective, the nature of this second problem favours (EC) against (W).

Competitive negotiators frequently use tactics which others view as "unethical", in that these tactics either violate standards of truth telling or violate the perceived rules of negotiation. This paper sought to determine how business students viewed a number of marginally ethical negotiating tactics, and to determine the underlying factor structure of these tactics. The factor analysis of these tactics revealed five clear factors which were highly similar across the two samples, and which parallel (to a moderate degree) categories of tactics (...) proposed by earlier theory. Data from one sample also permitted comparisons of the appropriateness of certain tactics across gender, nationality, ethnic origin and perception of one's negotiating style. (shrink)

The paper argues against Peacocke's moderate rationalism in modality. In the first part, I show, by identifying an argumentative gap in its epistemology, that Peacocke's account has not met the Integration Challenge. I then argue that we should modify the account's metaphysics of modal concepts in order to avoid implausible consequences with regards to their possession conditions. This modification generates no extra explanatory gap. Yet, once the minimal modification that avoids those implausible consequences is made, the resulting account cannot support (...) Peacocke's moderate rationalism. (shrink)

Miss Arendt is more reticent than, perhaps, she should be, about what actually went on in this public realm of the Greeks. —W. H. Auden.

This paper argues that in Eudemian Ethics 8.3, virtue’s mean between excess and deficiency is defined by the standard of promoting the most contemplation. Promotion is indirect and constrained by virtue’s other essential features. The chapter’s apparent restriction of the standard to actions concerning natural goods actually serves a dialectical, not a restrictive, purpose. This paper proposes to unify the chapter’s argumentative arc.

‘Feminist logic’ may sound like an impossible, incoherent, or irrelevant project, but it is none of these. We begin by delineating three categories into which projects in feminist logic might fall: philosophical logic, philosophy of logic, and pedagogy. We then defuse two distinct objections to the very idea of feminist logic: the irrelevance argument and the independence argument. Having done so, we turn to a particular kind of project in feminist philosophy of logic: Valerie Plumwood's feminist argument for a relevance (...) logic. Plumwood's work serves as our primary case study as we turn to the project of considering three different ways we might understand her argument and revisionist arguments like it: as a priori theorizing, as ameliorative conceptual engineering, or as instances of anti-exceptionalist approaches to logic. After arguing that the anti-exceptionalist approach seems to provide the most promising means of understanding the kind of project undertaken in a feminist challenge to classical logic, we briefly address the consequences that this might have for logic instruction. Here, we argue for the perhaps unexpected conclusion that feminist programs ought to offer more, not less, instruction in logic for those who take interest. (shrink)

According to the early Yogācāra, following non-conceptual awareness, the advanced bodhisattva is said to attain a state characterized by a "subsequent awareness". Yogācāra thinkers identify this state with ultimate knowledge of causality and view it as involving a unique kind of conceptual activity and propositional attitudes, which are very different, however, from ordinary conceptual awareness insofar as they do not involve vikalpa. Translated back into the terms of some version of the contemporary debate between conceptualists and nonconceptualists, this would amount (...) to something like the claim that we can use concepts in a non-conceptual way. But how can we make sense... (shrink)

Pace Necessitism – roughly, the view that existence is not contingent – essential properties provide necessary conditions for the existence of objects. Sufficiency properties, by contrast, provide sufficient conditions, and individual essences provide necessary and sufficient conditions. This paper explains how these kinds of properties can be used to illuminate the ontological status of merely possible objects and to construct a respectable possibilist ontology. The paper also reviews two points of interaction between essentialism and modal logic. First, we will briefly (...) see the challenge that arises against S4 from flexible essential properties; as well as the moves available to block it. After this, the emphasis is put on the Barcan Formula (BF), and on why it is problematic for essentialists. As we will see, Necessitism can accommodate both (BF) and essential properties. What necessitists cannot do at the same time is to continue to understanding essential properties as providing necessary conditions for the existence of individuals; against what might be for some a truism.

Charitable interpreters of David Hume set aside his sprinkles of piety. Better to read him as lying than as clumsily inconsistent. We argue that the attribution of lies can pay dividends in historical scholarship no matter how strongly the theorist condemns lying. Accordingly, we show that our approach works even with one of the strongest condemners of lying: Immanuel Kant. We argue that Kant lied in his scholarly work and even in the first Critique. And we defend the claim that (...) this lie attribution, strange as it may sound, amounts to a kind of scholarly charity. (shrink)

At the turn of the nineteenth century, Friedrich Schlegel developed an influential theory of irony that anticipated some of the central concerns of postmodernity. His most vocal contemporary critic, the philosopher Hegel, sought to demonstrate that Schlegel’s theory of irony tacitly relied on certain problematic aspects of Fichte’s philosophy. While Schlegel’s theory of irony has generated seemingly endless commentary in recent critical discourse, Hegel’s critique of Schlegelian irony has gone neglected. This essay’s primary aim is to defend Hegel’s critique of (...) Schlegel by isolating irony’s underlying Fichtean epistemology. Drawing on Søren Kierkegaard’s The Concept of Irony in the final section of this essay, I argue that Hegel’s critique of irony can motivate a dialectical hermeneutics that offers a powerful alternative both to Paul de Man’s poststructuralist hermeneutics and to recent cultural-studies-oriented criticism that tends to reduce literary texts to sociohistorical epiphenomena.

Due to the influence of Nathan Salmon’s views, endorsement of the “flexibility of origins” thesis is often thought to carry a commitment to the denial of S4. This paper rejects the existence of this commitment and examines how Peacocke’s theory of the modal may accommodate flexibility of origins without denying S4. One of the essential features of Peacocke’s account is the identification of the Principles of Possibility, which include the Modal Extension Principle (MEP), and a set of Constitutive Principles. Regarding (...) their modal status, Peacocke argues for the necessity of MEP, but leaves open the possibility that some of the Constitutive Principles be only contingently true. Here, I show that the contingency of the Constitutive Principles is inconsistent with the recursivity of MEP, and this makes the account validate S4. It is also shown that, compatibly with the necessity of the Constitutive Principles, the account can still accommodate intuitions about flexibility of origins. However, the account we end up with once those intuitions are consistently accommodated may not be satisfactory, and this opens up the debate about whether or not artefacts allow for some variation in their origins.

The study was carried out. out during the 2nd semester of S.Y. 2023–2024. The respondents were chosen using the approach of purposive sampling. The research study employed an experimental approach and utilized quantitative research. Through the use of of a one-group pre- and post-test, the researcher was able to gather the (...) necessary data. The study included statistical measures such as percentages, means, and standard deviations, as well as dependent and independent t-tests, to assess and compare the proficiency and efficacy of utilizing video-based educational materials among students at Satriwithaya School in Bangkok, Thailand. Study findings also revealed that there is a significant difference in pre- and post-test assessment scores before and after using the video-based instructional materials. The research outcomes indicated that the application of video-based teaching resources as an instructional strategy in the field of biology resulted in an increased degree of effectiveness in the students' learning process. The findings of the study suggest that the utilization of video-based instructional materials has favorable outcomes in terms of enhancing pedagogical and educational achievements in the field of biology. This methodology has been demonstrated to provide learners with with the chance to enhance their comprehension through active participation, cultivate their imagination and cleverness, consequently facilitating enhanced educational achievements. Furthermore, the establishment of a conducive learning atmosphere that is both engaging and pleasurable for students can enhance their overall learning experience. Moreover, this approach enhances the teacher's capacity to convey their intended educational objectives to their students proficiently. -/- . (shrink)

Coleridge rarely mentions Hegel in his philosophical writings and seems to have read very little of Hegel's work. Yet I argue that Coleridge's criticisms of Schelling's philosophy—as recorded in letters and marginalia—betray remarkable intellectual affinities with his nearly exact contemporary Hegel, particularly in their shared doubts about Schelling's foundationalist intuitionism. With this background in place, I seek to demonstrate that volume one of Coleridge's Biographia Literaria is a radically self-undermining text: its philosophical argument, far from slavishly recapitulating Schelling's philosophy, remains (...) haunted by a quasi-Hegelian skepticism toward intuition even as it advances intuition as the foundation of its theoretical edifice.

Notions such as śūnyatā, catuṣkoṭi, and Indra's net, which figure prominently in Buddhist philosophy, are difficult to readily accommodate within our ordinary thinking about everyday objects. Famous Buddhist scholar Nāgārjuna considered two levels of reality: one called conventional reality, and the other ultimate reality. Within this framework, śūnyatā refers to the claim that at the ultimate level objects are devoid of essence or "intrinsic properties", but are interdependent by virtue of their relations to other objects. Catuṣkoṭi refers to the claim (...) that four truth values, including contradiction, are admissible in reasoning. Indra's net refers to the claim that every part of a whole is reflective of the whole. Here we present category theoretic constructions that are reminiscent of these Buddhist concepts. The universal mapping property definition of mathematical objects, wherein objects of a universe of discourse are defined not in terms of their content, but in terms of their relations to all objects of the universe is reminiscent of śūnyatā. The objective logic of perception, with perception modeled as [a category of] two sequential processes (sensation followed by interpretation), and with its truth value object of four truth values, is reminiscent of the Buddhist logic of catuṣkoṭi. The category of categories, wherein every category has a subcategory of sets with zero structure within which every category can be modeled, is reminiscent of Indra's net. Our thorough elaboration of the parallels between Buddhist philosophy and category theory can facilitate better understanding of Buddhist philosophy, and bring out the broader philosophical import of category theory beyond mathematics.

This article delves into the profound philosophy of Vedanta, a cornerstone of Hinduism, which explores the ultimate nature of reality and existence. Rooted in the canonical texts—the Upanishads, Brahmasutras, and Bhagavad-Gita—Vedanta addresses life's most essential questions: Who are we? And What is our purpose? It introduces Brahman, the infinite foundation of all, and provides pathways to realization through the Mahavakyas (Great Sayings). Through a blend of timeless wisdom and practical relevance, this article reveals Vedanta's potential to transform modern lives by (...) fostering self-awareness, liberation (Moksha), and universal harmony.

Science increases understanding, and offers more and more approximate natural explanations. The process of rationality uncovering patterns as well as causes constitutes scientific inquiry. This book is a multidisciplinary study of the mind body problem. Hypothesis of this book challenges reductionist-scientists identification of mind and body, and the so-called common-sense religious dualism of soul-in-the-machine of the body. Though human mind cannot be disserved from its neuronal correlates as a separate entity, it is irreducible to the brain. If mind and brain (...) are neither two dichotomised substance nor one and the same substance, then what is it? As the brain is made up of components, even the thoughts or the self, in some sense, are emergent properties of those components. But how? Answer to these questions consist in the ubiquitous phenomenon of emergence. The inquiry incorporates essential themes such as complexity, system dynamics, emergence, cosmological-biological evolution, thermodynamics and evolution. Human mind as the emergent functionality of the human brain is a biological system embedded in the universe that has thermodynamic-evolutionary history. The universe, which is a matter-energy-information system, actualised in time and space, becomes conscious of itself at least through one of its invention viz. human mind-brain. (shrink)

Our conscious experiences are qualitative and unitary. The qualitative universals given in particular experiences, i.e. qualia, combine into the seamless unity of our conscious experience. The problematics of quality and cohesion are not unique to consciousness studies. In mathematics, the study of qualities (e.g., shape) resulting from quantitative variations in cohesive spaces led to the axiomatization of cohesion and quality. Using the mathematical definition of quality, herein we model qualia space as a categorical product of qualities. Thus modeled qualia space (...) is a codomain space wherein composite qualities (e.g. shape AND color) of conscious experiences can be valued. As part of characterizing the qualia space, we provide a detailed exemplification of the mathematics of quality and cohesion in terms of the categories of idempotents and reflexive graphs. More specifically, with qualities as commutative triangles formed of cohesion-preserving functors, first we calculate the product of commutative triangles. Next, we explicitly show that the category of idempotents is a quality type. Lastly, as part of showing that the category of reflexive graphs is cohesive, we characterize the adjointness between functors relating cohesive graphs to discrete sets. In conclusion, our category theoretic construction of qualia space is a formalization of the binding of qualitative features (colors and shapes) into the cohesive objects (colored-shapes) of conscious experiences. Compared to the feature-vector accounts of conscious experiences, our product-of-qualities account of consciousness is a substantial theoretical advance. (shrink)

Comics comprise a hybrid art form descended from printmaking and mostly made using print technologies. But comics are an art form in their own right and do not belong to the art form of printmaking.

In the proof-theoretic semantics approach to meaning, harmony , requiring a balance between introduction-rules (I-rules) and elimination rules (E-rules) within a meaning conferring natural-deduction proof-system, is a central notion. In this paper, we consider two notions of harmony that were proposed in the literature: 1. GE-harmony , requiring a certain form of the E-rules, given the form of the I-rules. 2. Local intrinsic harmony : imposes the existence of certain transformations of derivations, known as reduction and expansion . We propose (...) a construction of the E-rules (in GE-form) from given I-rules, and prove that the constructed rules satisfy also local intrinsic harmony. The construction is based on a classification of I-rules, and constitute an implementation to Gentzen’s (and Pawitz’) remark, that E-rules can be “read off” I-rules. (shrink)

In this paper we compare the propositional logic of Frege’s Grundgesetze der Arithmetik to modern propositional systems, and show that Frege does not have a separable propositional logic, definable in terms of primitives of Grundgesetze, that corresponds to modern formulations of the logic of “not”, “and”, “or”, and “if…then…”. Along the way we prove a number of novel results about the system of propositional logic found in Grundgesetze, and the broader system obtained by including identity. In particular, we show that (...) the propositional connectives that are definable in terms of Frege’s horizontal, negation, and conditional are exactly the connectives that fuse with the horizontal, and we show that the logical operators that are definable in terms of the horizontal, negation, the conditional, and identity are exactly the operators that are invariant with respect to permutations on the domain that leave the truth-values fixed. We conclude with some general observations regarding how Frege understood his logic, and how this understanding differs from modern views. (shrink)

The paper briefly surveys the sentential proof-theoretic semantics for fragment of English. Then, appealing to a version of Frege’s context-principle (specified to fit type-logical grammar), a method is presented for deriving proof-theoretic meanings for sub-sentential phrases, down to lexical units (words). The sentential meaning is decomposed according to the function-argument structure as determined by the type-logical grammar. In doing so, the paper presents a novel proof-theoretic interpretation of simple type, replacing Montague’s model-theoretic type interpretation (in arbitrary Henkin models). The domains (...) of derivations are collections of derivations in the associated “dedicated” natural-deduction proof-system, and functions therein (with no appeal to models, truth-values and elements of a domain). The compositionality of the semantics is analyzed. (shrink)

In this paper, the sine, cosine and cotangent similarity measures of interval rough neutrosophic sets is proposed. Some properties of the proposed measures are discussed.

We define consciousness as the category of all conscious experiences. This immediately raises the question: What is the essence in which every conscious experience in the category of conscious experiences partakes? We consider various abstract essences of conscious experiences as theories of consciousness. They are: (i) conscious experience is an action of memory on sensation, (ii) conscious experience is experiencing a particular as an exemplar of a general, (iii) conscious experience is an interpretation of sensation, (iv) conscious experience is referring (...) sensation to an object as its cause, and (v) conscious experience is a model of stimulus. Corresponding to each one of these theories we obtain a category of models of conscious experiences: (i) category of actions, (ii) category of idempotents, (iii) category of two sequential maps, (iv) category of brain-generalized figures, and (v) functor categories with intuition as base and conceptual repertoire as exponent, respectively. For each theory of consciousness we also calculate its truth value object and characterize the objective logic intrinsic to the corresponding category of models of consciousness experiences.

Communication is the basic function of human beings that has been widely discussed in different fields of study. Different models, theories, and interpretations are available, but this paper aims to explain the importance of intrapersonal communication and its relationship with interpersonal communication. Different philosophers describe communication in various ways. However, Indian thinkers focus on intrapersonal communication and it can be the medium of interpersonal communication. According to the Indian model, a complete picture of communication cannot be thought of without considering (...) the in-depth and holistic view of human beings, their goal in life, and their interrelation with society, and the world at large. According to the Indian tradition, Śabda (words) originated from Nad-Brahma or Śabda-Brahma and it has four aspects: Para, Pashyanty, Madhyama, and Vaikhary. Similarly, according to the Indian approach, self-realisation is the primary goal, and knowing oneself is the beginning of all wisdom. Thus, communication from the Indian point of view has a deeper/wider meaning. This paper finds out the qualitative outcome of intrapersonal communication. Most of the people do not know that intrapersonal communication happens in themselves. Moreover, it can be a part of our daily activities, hence, one can be able to reduce conflicts, suffering so on. It is a firm conviction that intrapersonal communication is the foundation of all other interpersonal communication. Without a proper understanding of intrapersonal communication, it would be difficult to achieve our desired goal. The method of this communication depends on praying, meditation, reflection, etc. and with the help of these one should be able to interact with own self, recognize own self, to know the strengths and weaknesses. Therefore, one can be aware of own self. (shrink)

In this paper, we define projection and bidirectional projection measures between interval rough neutrosophic sets and prove their basic properties. Then two new multi attribute decision making strategies are proposed based on interval rough neutrosophic projection and bidirectional projection measures respectively. Then the proposed methods are applied for solving multi attribute decision making problems. Finally, a numerical example is solved to show the feasibility, applicability and effectiveness of the proposed strategies.

One of the most popular facets of Schmitt's philosophy is his theory of sovereignty and decisionism, as developed in his early essay Political Theology (1922). There, Schmitt offers an original outlook on the political implications of the secularization of modern Europe and philosophy's purported turn away from theology. The “death of God,” along with the gradual disappearance of the political institution of monarchy, are only symbols of the decline of sovereignty in general.
