Classical realism is enjoying a renaissance in the study of international relations. It is well known that the analytical and normative international-political thought of early 20th-century classical realists is based on assumptions about human nature. Yet current knowledge of these assumptions remains limited. This article therefore revisits and examines the nature and intellectual roots of the human nature assumptions of three truly consequential classical realists. The analysis shows — similar to the causa Hans J. Morgenthau — (...) that the human nature assumptions of George F. Kennan, Walter Lippmann and E. H. Carr are — to varying degrees — Freudian. Unless this hitherto neglected dimension is recognized, an understanding of their international-political thought and of the political philosophy of realism remains incomplete. Two conclusions are presented. First, current criticism of classical realism’s human nature assumptions is unjustified. Second, any (re-) engagement with classical realism must recognize its human nature baggage. Realist international-political theorizing is necessarily human nature-based international-political theorizing. (shrink)

This paper introduces some of the major themes of An Unwritten Future: Realism and Uncertainty in World Politics, and provides a short illustration of how the analytical apparatus elaborated there can offer fruitful insights into understanding enduring puzzles in international relations. An Unwritten Future explores, illuminates and interrogates Classical Realism, an approach to the study of world politics that is contrasted with Structural Realism and with the ‘hyper-rationalist’ perspective associated with the ‘Rationalist Explanations for War’ school (...) of thought. It elucidates the fundamental flaws of those two highly influential paradigms, and explains why Classical Realism, with its emphasis on what Structural Realism and Hyper-rationalism forbid—content, purpose, history, and irreducible uncertainty—provides a more promising and productive point of departure for students of international relations.

The theses maintained in Professor Martin's work are of two quite different types: theses about the natures and interrelations of the various kinds of knowledge and theses about the true philosophy and the false ones. The true philosophy is classical realism, the philosophy of "the Aristotelian-Aquinas tradi- tion". What is the relation between these two kinds of theses, between Mr. Martin's theory of the order and integration of knowledge, on the one hand, and his classical realism, (...) on the other? Although Mr. Martin's view on this question is not entirely clear, it seems to be the following: "Moderate realism is the most adequate metaphysical position to account for the nature and kinds of knowledge"; but "this adequacy, in itself, is not sufficient for demonstrating the truth of realism. Rather it is one sign, among others, of its truth." We shall return to this question of the relation between these two kinds of theses after considering them separately. Since my own philosophical background and orientation tend to be similar to Mr. Martin's, the following discussion may present only an insider's view, though one more positively influenced by outsiders than is Mr. Martin's.

Although David Mitrany’s international thought is not usually associated with the concept of the international anarchy, I argue that his analysis actually compares two forms of anarchical order. The first form is the order associated with the relations between states, while the second is his functional alternative to this order. The functional approach is anarchical in the sense that it remains an order without an orderer. In first analysing the dynamics and failings of the inter-state order, and then suggesting pragmatic (...) process-orientated solutions to those failings, I argue that Mitrany follows a similar approach to his classical realist contemporaries.

The article shows that three antirealistic theories of classical analysis and synthesis are logically possible: presentationistic, solipsistic and Kantian, but only the latter is actually being developed. Revealed its specific features and features shared with other, logically possible antirealistic theories. The correlation of the Kantian theory of analysis and synthesis of knowledge with his theory of analysis and synthesis of subjects of knowledge is analyzed. Gnoseological problems that forced Kant to assert that new knowledge is provided only by the (...) synthesis of knowledge, and analysis only clarifies the results of synthesis, are characterized. The Kantian solution to these problems is correlated with their realistic solution. The role that the Kantian "Copernican revolution in philosophy" plays in his interpretation of the analysis and synthesis of subjects of knowledge is investigated. The Kantian theory of analytical and synthetic judgments is considered. It is shown that the Kantian question "how are synthetic judgments a priori possible?" is essentially a question about the nature of theoretical knowledge, which was historically formed in ancient geometry precisely as the unity of analysis and synthesis. A qualitative difference is shown between classical and geometric (by origin) analysis and synthesis. Three historical stages of their formation are described. The assertion of I. Newton that the natural science experiment arose as a result of the extension of the method of geometric analysis and synthesis to the natural sciences is investigated. (shrink)

In an enlightening dialogue with Descartes, Kant, Husserl and Gadamer, Professor Seifert argues that the original inspiration of phenomenology was nothing other than the primordial insight of philosophy itself, the foundation of philosophia perennis .

In order to validate the classical claim to know autonomous being, the author defends Husserl's methodological principle "Back to things themselves" from empiricist and (...) idealist critics, including the later Husserl, and replies to the arguments of Kant which attempt to discredit the knowability of things in themselves. Originally published in 1982, this book culminates in a phenomenological and critical unfolding of the Augustinian cogito , as giving access to immutable truth about necessary essences and the real existence of personal being.

PREFACE Towards the end of his important article 'What is Phenomenology?" Adolf Reinach writes: When we wish to break with all theories and constructions in ...

Seifert explains here the distinctiveness of the method of phenomenology and, above all, seeks to reclaim the method from the idealists and for classical realism. The main question of the book is: "In our knowledge, do we also discover besides the appearances and constituted aspects of things, 'things themselves,' i.e., essential structures and laws, and existents, which are in no way constituted by human consciousness?".

In this paper we discuss the representational realist stance as a pluralist ontic approach to inter-theoretic relationships. Our stance stresses the fact that physical theories require the necessary consideration of a conceptual level of discourse which determines and configures the specific field of phenomena discussed by each particular theory. We will criticize the orthodox line of research which has grounded the analysis about QM in two metaphysical presuppositions —accepted in the present as dogmas that all interpretations must follow. We will (...) also examine how the orthodox project of "bridging the gap" between the quantum and the classical domains has constrained the possibilities of research, producing only a limited set of interpretational problems which only focus in the justification of "classical reality" and exclude the possibility of analyzing the possibilities of non-classical conceptual representations of QM. The representational realist stance introduces two new problems, namely, the superposition problem and the contextuality problem, which consider explicitly the conceptual representation of orthodox QM beyond the mere reference to mathematical structures and measurement outcomes. In the final part of the paper, we revisit, from a representational realist perspective, the quantum to classical limit and the orthodox claim that this inter-theoretic relation can be explained through the principle of decoherence.

The standard conception of God is that of a necessary being. On a possible worlds semantics, this entails that God exists at every possible world. According to the modal realist account of David Lewis, possible worlds are understood to be real, concrete worlds—no different in kind from the actual world. Some have argued that Lewis’s view is incompatible with classical theism (e.g., Sheehy, 2006). More recently, Ross Cameron (2009) has defended the thesis that Lewisian modal realism and (...) class='Hi'>classical theism are in fact compatible. I argue that this is not the case. Modal realism, I argue, is equipped to accommodate necessary beings in only one of three ways: (1) By way of counterpart theory, or (2) by way of a special case of trans-world identity for causally inert necessary beings (e.g., pure sets), or else (3) causally potent ones which lack accidental intrinsic properties. However, each of these three options entails unacceptable consequences—(1) and (2) are incompatible with theism, and (3) is incompatible with modal realism. I conclude that (at least) one of these views is false. (shrink)

In this paper, by suggesting a formal representation of science based on recent advances in logic-based Artificial Intelligence (AI), we show how three serious concerns around the realisation of traditional scientific realism (the theory/observation distinction, over-determination of theories by data, and theory revision) can be overcome such that traditional realism is given a new guise as ‘naturalised’. We contend that such issues can be dealt with (in the context of scientific realism) by developing a formal representation of (...) science based on the application of the following tools from Knowledge Representation: the family of Description Logics, an enrichment of classical logics via defeasible statements, and an application of the preferential interpretation of the approach to Belief Revision.

I sketch an application of a semantically anti-realist understanding of the classical sequent calculus to the topic of mathematics. The result is a semantically anti-realist defence of a kind of mathematical realism. In the paper, I begin the development of the view and compare it to orthodox positions in the philosophy of mathematics.

In Free Market Fairness, John Tomasi defends classical-liberal principles not because of real-world considerations but on ideal-theoretic grounds. However, what constitutes a sufficiently “ideal” ideal theory is debatable since, as Tomasi shows, regimes that range from laissez faire to heavily interventionist can all be classified as legitimate from the perspective of ideal theory. Conversely, if ideal theory can allow for realistic constraints, as Rawls does, then we should recognize that even under ideal-theoretic conditions, political actors face logistical, epistemic, and (...) motivational challenges that only intensify in the real world, where questions of feasibility become paramount.

The article shows that all modern theories of analysis and synthesis, on one basis, are divided into classical and non-classical, and on the other, into realistic and anti-realistic. A realistic version of the classical theory, according to which analysis is a real or mental decomposition of the phenomena of the objective and subjective world into components, and synthesis is a real or mental combination of these components into a whole, is considered. The naive understanding of analysis, which (...) includes in its task the cognition of the components of the object under study, and those relations that form it from these components, has been criticized. It is shown that the cognition of such relations is a task of synthesis. The history of the study of the problem of mental synthesis from Plato to modern nominalism is considered. Mental analysis and synthesis are compared with practical ones. Two stages of the history of practical analysis and synthesis are investigated — pre-scientific and scientific. The theories of analysis and synthesis, formed at these stages, are compared. (shrink)

I argue that there are two ways of construing Wittgenstein’s slogan that meaning is use. One accepts the view that the notion of meaning must be explained in terms of truth-theoretic notions and is committed to the epistemic conception of truth. The other keeps the notion of meaning and the truth-theoretic notions apart and is not committed to the epistemic conception of truth. I argue that Dummett endorses the first way of construing Wittgenstein’s slogan. I address the issue by discussing (...) two of Dummett’s arguments against the realist truth-theoretic conception of meaning: the manifestation argument and the argument for the unintelligibility of classical logic. I examine the dialectic of those arguments and show that they rest on the assumption that meaning needs to be explained in terms of truth-theoretic notions.Tvrdim da postoje dva načina shvaćanja Wittgensteinova slogana da je značenje upotreba. Jedno prihvaća gledište da se pojam značenja mora objasniti na osnovi istinitosnoteoretskih pojmova te je obvezano na epistemičku koncepciju istine. Drugo pojam značenja i istinitosnoteoretske pojmove drži odvojenima te nije obvezano na epistemičku koncepciju istine. Tvrdim da Dummett prihvaća prvo shvaćanje Wittgensteinova slogana. Problemu pristupam tako što raspravljam o dvama Dummettovim argumentima protiv realističke istinitosnoteoretske koncepcije značenja: o argumentu iz manifestacije i argumentu za neshvatljivost klasične logike. Ispitujem dijalektiku tih argumenata i pokazujem da počivaju na pretpostavci da se značenje mora objasniti na osnovi istinitosnoteoretskih pojmova. (shrink)

The usefulness of ‘realism’ in explaining Russia’s decision to invade Ukraine has become a keenly contested debate not only in International Relations but in wider public intellectual discourse since the onset of the war in February 2022. At the centre of this debate is the punditry of John J. Mearsheimer, a prominent offensive realist who is a Professor of International Relations at the University of Chicago. This article argues that although Mearsheimer is indeed a realist, his offensive realism (...) is but one of many different realist theories that can forward an explanation of the Ukraine War. Beyond the apparent hegemony of structural realism (the branch of realism to which Mearsheimer’s offensive realism belongs), it is argued that classical and neoclassical realist frameworks can provide more nuanced and, ultimately, convincing arguments as to why Russian President Vladimir Putin decided to invade Ukraine. This is because both classical and neoclassical realism can incorporate insights from non-realist studies—such as the concepts of civilization and ontological security—and combine them into an overarching power politics framework. Although neither classical nor neoclassical realism is flawless in their explanations, they demonstrate that realism does not just have to be about international power structures but can offer multivariate accounts of why a state, like Russia, decided to act, such as invading Ukraine.

This article elaborates local selective realism in view of the shifting from classical to quantum electrodynamics. After some introductory remarks, we critically address what we call global selective realism, hence setting forth the background for outlining local selective realism. When examining the transition from classical to quantum electrodynamics, we evaluate both continuities and discontinuities in observational features, mathematical structures, and ontological presuppositions. Our argument leads us to criticise the narrow understanding of limiting-case strategies, and to (...) reject the claim that we need a fully coherent theoretical framework to account for the transition from one theory to its successor in the case of electrodynamics. We close with a few remarks on the scope of local selective realism. (shrink)

What is Chinese Realism and how to update its research program? Realism analyses the world as it is – not as it should be. Realists, then, propose dealing with actual, real-world problems using actual, real-world instruments, such as incentives, rewards, and punishments. Once a major power in classical Chinese philosophy, Realism, or Legalism, fell out of favor early on in Chinese history. Its ideas, however, remain alive and powerful. This edited volume shows that many of the (...) Legalist recipes for creating strength, security, and order can still be applied today. Whether in international relations or corporate ethics, whether in the organization of the public sector or in the role that bureaucrats and politicians play, Realism offers unique ways of aligning these inherently particularistic actions with the broader common good.

Famously, Michael Dummett argues that considerations concerning the role of language in communication lead to the rejection of classical logic in favor of intuitionistic logic. Potentially, this results in massive revisions of established mathematics. Recently, Neil Tennant (“The law of excluded middle is synthetic a priori, if valid”, Philosophical Topics 24 (1996), 205-229) suggested that a Dummettian anti-realist can accept the law of excluded middle as a synthetic, a priori principle grounded on a metaphysical principle of determinacy. This article (...) shows that the for the anti-realist, the law of excluded middle entails that humans have wildly implausible abilities. The proposed synthesis between anti-realism and classical mathematics thus fails. (shrink)

The dissertation falls into two sections. Part I deals with classical pragmatist arguments against the correspondence theory of truth; Part II , with neo-pragmatist arguments against the possibility of a substantive theory of knowledge. The goal of Part I is to reconstruct and evaluate the main anti-correspondence arguments employed by the classical pragmatists and contemporary neo-pragmatists . Here we offer detailed critical and historical discussions of two arguments in particular: the comparison objection, which claims that the idea that (...) truth is a matter of correspondence with the facts leads directly to skepticism; and the constructivist or anti-realist objection, according to which the correspondence theory is tenable only if realism is defensible, and thus cannot survive the latter position's fall from grace. After considering these objections, we address what James and Dewey had to say about the nature of the correspondence relation itself, and urge that their position has been badly misunderstood by foes and friends alike. Part II deals with the misgivings neo-pragmatists have about the very idea of a philosophical "theory of knowledge." Within analytic philosophy, the most familiar and aggressive expression of this anti-epistemology attitude is Richard Rorty's Philosophy and the Mirror of Nature. However, Rorty is far from alone in declaring epistemology moribund: philosophers in both the Anglo-American and Continental traditions have been busy composing obituaries for some time now. Our primary aim in Part II is to refute two main arguments central to the neo-pragmatist anti-epistemology case: the arguments against "foundations", a heterogeneous family of four objections to the idea of epistemology as 'foundational'; and the anti-representationalist argument, according to which skepticism and epistemology itself are said to rest on an untenable representationalist conception of thought or language.

Since the outbreak of the war in the Ukraine, realism has made a comeback in public discourses but it is not clear what realism actually means as it seems to stand for everything: from supporting the Ukraine against Russian aggression to the war is the West’s fault. This is the result of decades of not distinguishing between neorealism and classical realism and implicitly acknowledging neorealist storytelling of having systematized classical realist thought. The present paper is (...) a further intervention to carefully distinguish between both theoretical perspectives to uncover what they can add to current world political problems. It finishes by asking if neorealist scholars like John Mearsheimer have a point that it is the West’s fault and a diplomatic solution needs to be found. They often refer to Hans Morgenthau not least because he was one of the most outspoken critics of the Vietnam War. (shrink)

Bohmian mechanics is a realistic interpretation of quantum theory. It shares the same ontology of classical mechanics: particles following continuous trajectories in space through time. For this ontological continuity, it seems to be a good candidate for recovering the classical limit of quantum theory. Indeed, in a Bohmian framework, the issue of the classical limit reduces to showing how classical trajectories can emerge from Bohmian ones, under specific classicality assumptions. In this paper, we shall focus on (...) a technical problem that arises from the dynamics of a Bohmian system in bounded regions; and we suggest that a possible solution is supplied by the action of environmental decoherence. However, we shall show that, in order to implement decoherence in a Bohmian framework, a stronger condition is required rather than the usual one. (shrink)

While most discussions of political realism in the West draw their inspiration from thinkers such as Thucydides, Machiavelli, and Hobbes, they were far from the only political theorists developing such an approach. Rather, we see realist approaches to politics not only in a vast array of European thinkers throughout history, but also in in a diverse range of non-European traditions. From Kautilya’s 2nd c. BCE Sanskrit classic to the eponymously named Han Feizi from China, a variety of realist visions (...) were developed alongside arguments detailing structural problems in the more idealist political visions of their rivals. One such thinker, whose ideas have largely been lost to the contemporary world was the Chinese philosopher Shen Dao (c. 350-275 BCE). -/- One of the most philosophical intriguing arguments Shen Dao develops focuses on the sources of political resentment and the necessity of eliminating them as a prerequisite to a strong and stable society and state. This essay develops Shen Dao’s argument that resentment arises not merely when people’s desires are not fulfilled but rather when there was an expectation that they could have been fulfilled and work to demonstrate how he envisions eliminating sources of resentment in the political sphere. In doing so, it engages with much more prevalent Confucian views, demonstrating that Shen Dao presents a trenchant criticism of one of the very bases of Confucian political philosophy and, indeed any political theory that develops itself from moral foundations. -/- This paper closes with an analysis of how Shen Dao’s ideas may be brought into conversation with those of political realists more familiar to a Western audience, with a goal of “pursuing the ideal of working with similarities in differences and differences in similarities.” In particular it raises the question for students of why the worries of resentment were not foregrounded in the West in the way that they were by Chinese realists. This provides students with entry into examining the ways in which different cultures approach very similar topics and allows us to more deeply reflect not only on why certain things were emphasized in a particular tradition but why others were de-emphasized or seemingly ignored.

Now acknowledged as a classic in the philosophy of science, A Realist Theory of Science is one of the very few books to transform not only our understanding of science, but that of the nature of the world it studies. The book has inspired the multi-disciplinary and international movement of thought known as critical realism. Re-issued with a new introduction.

Following the proposal of a new kind of selective structural realism that uses as a basis the distinction between framework and interaction theories, this work discusses relevant applications in fundamental physics. An ontology for the different entities and properties of well-known theories is thus consistently built. The case of classical field theories—including general relativity as a classical theory of gravitation—is examined in detail, as well as the implications of the classification scheme for issues of realism in (...) quantum mechanics. These applications also shed light on the different range of applicability of the ontic and epistemic versions of structural realism. (shrink)

A source of much difficulty and confusion in the interpretation of quantum mechanics is a naive realism about operators. By this we refer to various ways of taking too seriously the notion of operator-as-observable, and in particular to the all too casual talk about measuring operators that occurs when the subject is quantum mechanics. Without a specification of what should be meant by measuring a quantum observable, such an expression can have no clear meaning. A definite specification is provided (...) by Bohmian mechanics, a theory that emerges from Schrödinger's equation for a system of particles when we merely insist that particles means particles. Bohmian mechanics clarifies the status and the role of operators as observables in quantum mechanics by providing the operational details absent from standard quantum mechanics. It thereby allows us to readily dismiss all the radical claims traditionally enveloping the transition from the classical to the quantum realm — for example, that we must abandon classical logic or classical probability. The moral is rather simple: Beware naive realism, especially about operators! (shrink)

Blind Realism originated in the deeply felt conviction that the widespread acceptance of Gettier-type counterexamples to the classical definition of knowledge rests in a demonstrably erroneous understanding of the nature of human knowledge. In seeking to defend that conviction, Robert F. Almeder offers a fairly detailed and systematic picture of the nature and limits of human factual knowledge.

Minimally, causal realism (as understood here) is the view that accounts of causation in terms of mere, regular or probabilistic conjunction are unsatisfactory, and that causal phenomena are correctly associated with some form of de re necessity. Classic arguments, however, some of which date back to Sextus Empiricus and have appeared many times since, including famously in Russell, suggest that the very notion of causal realism is incoherent. In this paper I argue that if such objections seem compelling, (...) it is only because everyday expressions concerning causal phenomena are misleading with respect to certain metaphysical details. These expressions generally make reference to the relations of events or states of affairs, but ignore or obscure the role played by causal properties. I argue that on a proposed alternative, an analysis in terms of causal processes, more refined descriptions of causal phenomena escape the charge of incoherence. Causal necessity is here located in the relations of causal properties. I distinguish this view from the recent process theories of Salmon and Dowe, which are disinterested in causal realism.

The roles of classical realism, logical positivism, and pragmatic instrumentalism in the shaping of fundamental ideas in quantum physics are examined in the light of some recent historical and sociological studies of the factors that influenced their development. It is shown that those studies indicate that the conventionalistic form of instrumentalism that has dominated all the major post-World War II developments in quantum physics is not an outgrowth of the Copenhagen school, and that despite the “schism” in twentieth (...) century physics created by the Bohr-Einstein “disagreements” on foundational issues in quantum theory, both their philosophical stands were very much opposed to those of conventionalistic instrumentalism. Quotations from the writings of Dirac, Heisenberg, Popper, Russell, and other influential thinkers, are provided, illustrating the fact that, despite the various divergencies in their opinions, they all either opposed the instrumentalist concept of “truth” in general, or its conventionalistic version in post-World War II quantum physics in particular. The basic epistemic ideas of a quantum geometry approach to quantum physics are reviewed and discussed from the point of view of a quantum realism that seeks to reconcile Bohr's “positivism” with Einstein's “realism” by emphasizing the existence of an underlying quantum reality, in which they both believed. This quantum geometry framework seeks to introduce geometro-stochastic concepts that are specifically designed for the systematic description of that underlying quantum reality, by developing the conceptual and mathematical tools that are most appropriate for such a use.
