This essay develops an inferential account of model explanation, based on Mauricio Suárez’s inferential conception of scientific representation and Alisa Bokulich’s counterfactual account of model explanation. It is suggested that the fact that a scientific model can explain is essentially linked to how a modeler uses an established model to make various inferences about the target system on the basis of results derived from the model. The inference practice is understood as a two-step activity, with the first step involving making (...) counterfactual statements about the model itself and the second step involving making hypothetical statements transferring over claims derived from the model onto the target. To illustrate how this two-step activity proceeds, an agent-based simulation model is discussed. (shrink)

Polger and Shapiro argue that their official recipe, a criterion for judging when the phenomenon of multiple realization exists, renders MR less widespread than its proponents have assumed. I argue that, although Polger and Shapiro’s criterion is a useful contribution, they arrive at their conclusion too hastily. Contrary to Polger and Shapiro, I claim that the phenomenon of multiple realization in the biological world, judged by their criterion, is not as scarce as they suggest. To show this, an updated official (...) recipe, namely a multiple mechanistic realization thesis, integrating Polger and Shapiro’s criterion with a compositional conception of realization, is developed. Then, three examples of varied kinds are examined, showing that cases of MR are not so hard to find in the biological world. (shrink)

An endomorphism on an algebra \ is said to be strong if it is compatible with every congruence on \; and \ is said to have the strong endomorphism kernel property if every congruence on \, other than the universal congruence, is the kernel of a strong endomorphism on \. Here we characterise the structure of those double MS-algebras that have this property by the way of Priestley duality.

I propose a dynamic causal approach to characterizing the notion of a mechanism. Levy and Bechtel, among others, have pointed out several critical limitations of the new mechanical philosophy, and pointed in a new direction to extend this philosophy. Nevertheless, they have not fully fleshed out what that extended philosophy would look like. Based on a closer look at neuroscientific practice, I propose that a mechanism is a dynamic causal system that involves various components interacting, typically nonlinearly, with one another (...) to produce a phenomenon of interest.

Temporal Externalism posits the counterintuitive claim that the semantic properties of terms are influenced not only by present and past linguistic practices but also by future linguistic practices. In this paper, I primarily introduce a new challenge to Temporal Externalism, arguing that it presupposes a meta-belief about future linguistic practices but fails to explain how this belief relates to future properties. I then briefly highlight that Jussi Haukioja’s recent defense of Temporal Externalism still does not address the challenges posed by (...) this meta-belief. Therefore, I conclude that Temporal Externalism is untenable. (shrink)

Stephen Yablo’s notion of proportionality, despite controversies surrounding it, has played a significant role in philosophical discussions of mental causation and of high-level causation more generally. In particular, it is invoked in James Woodward’s interventionist account of high-level causation and explanation, and is implicit in a novel approach to constructing variables for causal modeling in the machine learning literature, known as causal feature learning (CFL). In this article, we articulate an account of proportionality inspired by both Yablo’s account of proportionality (...) and the CFL account of variable construction. The resulting account has at least three merits. First, it illuminates an important feature of the notion of proportionality, when it is adapted to a probabilistic and interventionist framework. The feature is that at the center of the notion of proportionality lies the concept of “determinate intervention effects.” Second, it makes manifest a virtue of (common types of) high-level causal/explanatory statements over low-level ones, when relevant intervention effects are determinate. Third, it overcomes a limitation of the CFL framework and thereby also addresses a challenge to interventionist accounts of high-level causation. (shrink)

Michael Weisberg’s account of scientific models concentrates on the ways in which models are similar to their targets. He intends not merely to explain what similarity consists in, but also to capture similarity judgments made by scientists. In order to scrutinize whether his account fulfills this goal, I outline one common way in which scientists judge whether a model is similar enough to its target, namely maximum likelihood estimation method. Then I consider whether Weisberg’s account could capture the judgments involved (...) in this practice. I argue that his account fails for three reasons. First, his account is simply too abstract to capture what is going on in MLE. Second, it implies an atomistic conception of similarity, while MLE operates in a holistic manner. Third, Weisberg’s atomistic conception of similarity can be traced back to a problematic set-theoretic approach to the structure of models. Finally, I tentatively suggest how these problems might be solved by a holistic approach in which models and targets are compared in a non-set-theoretic fashion. (shrink)

This essay considers a mixed-effects modeling practice and its implications for the philosophical debate surrounding reductive explanation. Mixed-effects modeling is a species of the multilevel modeling practice, where a single model incorporates simultaneously two (or even more) levels of explanatory variables to explain a phenomenon of interest. I argue that this practice makes the position of explanatory reductionism held by many philosophers untenable because it violates two central tenets of explanatory reductionism: single-level preference and lower-level obsession.

In this essay I suggest that we view design principles in systems biology as minimal models, for a design principle usually exhibits universal behaviors that are common to a whole range of heterogeneous (living and nonliving) systems with different underlying mechanisms. A well-known design principle in systems biology, integral feedback control, is discussed, showing that it satisfies all the conditions for a model to be a minimal model. This approach has significant philosophical implications: it not only accounts for how design (...) principles explain, but also helps clarify one dispute over design principles, e.g., whether design principles provide mechanistic explanations or a distinct kind of explanations called design explanations.

Polger and Shapiro (2016) claim that unlike human-made artifacts cases of multiple realization in naturally occurring systems are uncommon. Drawing on cases from systems biology, I argue that multiple realization in naturally occurring systems is not as uncommon as Polger and Shapiro initially thought. The relevant cases, which I draw from systems biology, involve generalizable design principles called network motifs which recur in different organisms and species and perform specific functions. I show that network motifs with entirely different underlying causal (...) structures can perform the same function of interest. The article also considers the scope problem of multiple realization.

This article argues for the explanatory autonomy of psychology drawing on cases from the multilevel modeling practice. This is done by considering a multilevel linear model in personality and social psychology, and discussing its philosophical implications for the reductionism debate in philosophy of psychology. I argue that this practice challenges the reductionist position in philosophy of psychology, and supports the explanatory autonomy of psychology.

Can an agent deliberating about an action A hold a meaningful credence that she will do A? 'No', say some authors, for 'Deliberation Crowds Out Prediction' (DCOP). Others disagree, but we argue here that such disagreements are often terminological. We explain why DCOP holds in a Ramseyian operationalist model of credence, but show that it is trivial to extend this model so that DCOP fails. We then discuss a model due to Joyce, and show that Joyce's rejection of DCOP rests (...) on terminological choices about terms such as 'intention', 'prediction', and 'belief'. Once these choices are in view, they reveal underlying agreement between Joyce and the DCOP-favouring tradition that descends from Ramsey. Joyce's Evidential Autonomy Thesis (EAT) is effectively DCOP, in different terminological clothing. Both principles rest on the so-called 'transparency' of first-person present-tensed reflection on one's own mental states. (shrink)

There is a long-standing disagreement in the philosophy of probability and Bayesian decision theory about whether an agent can hold a meaningful credence about an upcoming action, while she deliberates about what to do. Can she believe that it is, say, 70% probable that she will do A, while she chooses whether to do A? No, say some philosophers, for Deliberation Crowds Out Prediction (DCOP), but others disagree. In this paper, we propose a valid core for DCOP, and identify terminological (...) causes for some of the apparent disputes. (shrink)

Implicational tonoid logics and their extensions with abstract Galois properties have been introduced by Yang and Dunn. They introduced matrix semantics for the implicational tonoid logics but did not do for the extensions. Here we provide such semantics for implicational partial gaggle logics as one sort of such extensions. To this end, first we discuss implicational partial gaggle logics in Hilbert-style. We next introduce one kind of matrix semantics based on Lindenbaum– Tarski matrices for the logics and show that (...) those logics are complete with respect to the matrix semantics. Finally, we further introduce a slightly different kind of matrix semantics based on reduced models for the logics and show that those logics are complete with respect to this matrix semantics.

Sleep onset is associated with marked changes in behavioral, physiological, and subjective phenomena. In daily life though subjective experience is the main criterion in terms of which we identify it. But very few studies have focused on these experiences. This study seeks to identify the subjective variables that reflect sleep onset. Twenty young subjects took an afternoon nap in the laboratory while polysomnographic recordings were made. They were awakened four times in order to assess subjective experiences that correlate with the (...) (1) appearance of slow eye movement, (2) initiation of stage 1 sleep, (3) initiation of stage 2 sleep, and (4) 5 min after the start of stage 2 sleep. A logistic regression identified control over and logic of thought as the two variables that predict the perception of having fallen asleep. For sleep perception, these two variables accurately classified 91.7% of the cases; for the waking state, 84.1%. (shrink)

The deceptive clues in the impossible puzzle film confirm the viewer’s internal expectations and allow retrospective attributing. In the film, a transcendental object negates an internal expectation, causing a retrospective blockage. Retrospectivity does not stop there; the transcendental object reinterpreting deceptive clues in the associative area leads to repeated attribution. This article consists of three parts. First, it discusses impossible puzzle films in the context of complex narrative classification. The following section introduces the Jungian concept of synchronicity and illustrates how (...) it works. The article concludes with a case study of Long Day’s Journey into Night (2018), which contains more complicated puzzles and explains how mind-game narrative techniques create deceptive clues and induce deceptive retrospective attribution.

Wang Yangming’s doctrine of the “unity of knowing and acting” (zhi xing heyi 知行合一) can be traced back to Mencius’s theory of “original knowing” (liangzhi 良知). Similarly, Kant discussed the relationship of theory to practice on three different levels (morality, the law of the state, and international law) in his article, “On the Common Saying: This May Be True in Theory, But It Does Not Apply in Practice.” Kant proposed the unity of theory and practice on the level of morality. (...) So, this article uses Kant’s related concepts of theory and practice to interpret Wang’s doctrine of the “unity of knowing and acting” with the aim of clarifying some misinterpretations of it. Thereby, I argue that, although Wang Yangming put forward the doctrine of “the unity of knowing and acting” at a different time than his doctrines of “heart-mind is principle” (xin ji li 心即理) and “the extension of original knowing” (zhi liangzhi 致良知), these three doctrines are logically interconnected.

It is widely taken that the first-order part of Frege's Begriffsschrift is complete. However, there does not seem to have been a formal verification of this received claim. The general concern is that Frege's system is one axiom short in the first-order predicate calculus comparing to, by now, the standard first-order theory. Yet Frege has one extra inference rule in his system. Then the question is whether Frege's first-order calculus is still deductively sufficient as far as the first-order completeness is (...) concerned. In this short note we confirm that the missing axiom is derivable from his stated axioms and inference rules, and hence the logic system in the Begriffsschrift is indeed first-order complete.

This paper addresses the issue of finite versus countable additivity in Bayesian probability and decision theory -- in particular, Savage's theory of subjective expected utility and personal probability. I show that Savage's reason for not requiring countable additivity in his theory is inconclusive. The assessment leads to an analysis of various highly idealised assumptions commonly adopted in Bayesian theory, where I argue that a healthy dose of, what I call, conceptual realism is often helpful in understanding the interpretational value of (...) sophisticated mathematical structures employed in applied sciences like decision theory. In the last part, I introduce countable additivity into Savage's theory and explore some technical properties in relation to other axioms of the system. (shrink)

This paper addresses a set-theoretic completeness based on a relational semantics for fuzzy extensions of two versions Rt and R T of R (Relevance logic). To this end, two fuzzy logics FRt and FRT as extensions of Rt and R T, respectively, and the relational semantics, so called Routley-Meyer semantics, for them are first recalled. Next, on the semantics completeness results are provided for them using a set-theoretic way.

The notion of comparative probability defined in Bayesian subjectivist theory stems from an intuitive idea that, for a given pair of events, one event may be considered “more probable” than the other. Yet it is conceivable that there are cases where it is indeterminate as to which event is more probable, due to, e.g., lack of robust statistical information. We take that these cases involve indeterminate comparative probabilities. This paper provides a Savage-style decision-theoretic foundation for indeterminate comparative probabilities.

What is happiness? Is happiness about feeling good or about being good? Across five studies, we explored the nature and origins of our happiness concept developmentally and crosslinguistically. We found that surprisingly, children as young as age 4 viewed morally bad people as less happy than morally good people, even if the characters all have positive subjective states (Study 1). Moral character did not affect attributions of physical traits (Study 2), and was more powerfully weighted than subjective states in attributions (...) of happiness (Study 3). Moreover, moral character but not intelligence influenced children and adults’ happiness attributions (Study 4). Finally, Chinese people responded similarly when attributing happiness with two words, despite one (“Gao Xing”) being substantially more descriptive than the other (“Kuai Le”) (Study 5). Therefore, we found that moral judgment plays a relatively unique role in happiness attributions, which is surprisingly early emerging and largely independent of linguistic and cultural influences, and thus likely reflects a fundamental cognitive feature of the mind.

In this essay I propose that what design principles in systems biology and systems neuroscience do is to present abstract characterizations of mechanisms, and thereby facilitate mechanistic explanation. To show this, one design principle in systems neuroscience, i.e., the multilayer perceptron, is examined. However, Braillard (2010) contends that design principles provide a sort of non-mechanistic explanation due to two related reasons: they are very general and describe non-causal dependence relationships. In response to this, I argue that, on the one hand, (...) all mechanisms are more or less general (or abstract), and on the other, many (if not all) design principles are causal systems. (shrink)

Lack of a historical sense is the hereditary defect of philosophers. … So what is needed from now on is historical philosophizing, and with it the virtue of modesty.

This paper offers a fine analysis of different versions of the well known sure-thing principle. We show that Savage's formal formulation of the principle, i.e., his second postulate (P2), is strictly stronger than what is intended originally.

Since 2019, Northeastern post-industrial culture has been a popular topic of discussion; the general public refers to it as the Northeastern Renaissance. Crises of identity, honor, and faith have been recurring themes in several Northeastern films released in recent years. Furthermore, these cinematic narratives frequently generate somber humor by presenting an enormous contrast between ideals and actuality. The article examines how the post-industrial narrative context of Northeast China has influenced audio-visual cultural products and contemporary Chinese popular culture. To elucidate the (...) fundamental aspect of the Northeast narrative, the article’s author employs the absurd theory of Albert Camus. The main structure and viewpoints of the article are as follows: The first is after presenting individuals’ contemplations on the Northeastern Renaissance-instigated post-industrial narrative of the Northeast. In the following sections, the article explores the narrative context of post-industrial audio-visual works in Northeast China, focusing on the absurdity depicted in the documentary Tie Xi Qu: West of the Tracks (2002). The authors’ analysis reveals how the documentary captures the socio-economic decline and the resulting human experiences of absurdity and dislocation. Key findings indicate that the narrative structure and visual style effectively convey the bleak realities of post-industrial life, offering critical insights into the region’s socio-cultural transformation. These findings suggest that future research should explore the intersection of visual media and social change in other post-industrial contexts. -/- . (shrink)

This short paper has two parts. First,we prove a generalisation of Aumann’s surprising impossibility result in the context of rational decision making. We then move, in the second part, to discuss the interpretational meaning of some formal setups of epistemic models, and we do so by means of presenting an interesting puzzle in epistemic logic. The aim is to highlight certain problematic aspects of these epistemic systems concerning first/third-person asymmetry which underlies both parts of the story. This asymmetry, we argue, (...) reveals certain limits of what epistemic models can be. (shrink)

Reduplicative approaches to the incarnation attempt to avoid the charge of incoherence by employing a qua-operator that operates on an entire assertion. The main objection to this approach is that it still yields a contradiction. Recently, two new reduplicative approaches have been offered that purport to avoid contradiction, one that offers a novel analysis of negative predications and the other which prevents conjoining divine and human predicates into a meaningful sentence. In this paper, I argue that these newer approaches either (...) fail to provide a distinctive solution or do not show whether the model is genuinely possible. (shrink)

It has been long debated whether quantum mechanics is real or complex. Local experiments have been carried out confirming the complex nature of quantum mechanics in the standard formalism. Nevertheless, recent theoretical work demonstrated that in a closed universe, quantum mechanics is real. We discuss the philosophical implications of whether quantum mechanics is real or complex.

The article summarizes the software tool on astrophysical analysis with multi-wavelength space telescope data. It recaps the evidence analysis conducted on the Kerr-Newman black hole (KNBH). It was written prior to the article Research on the Kerr-Newman Black Hole in M82 Confirms Black Hole and White Hole Juxtapose not soon after the experiment. The conducted analysis suggested Hawking radiation is caused by the movement of ergosurfaces of the BH and serves as the primal evidence for black hole and white hole (...) juxtapose. A later data exploration was conducted with the radiation trails in the multi-wavelength data. The evidences produced corroborates with Yale professor Priyamvada Natarajan's black hole seeds theory. It implies that the electromagnetic dynamic of fusion and fission temperature determines the pressure of surface tension on the macro particles, and the mass density of the BH is determined by the electromagnetic tension between the outer ergosurface and inner ergosurface. The ring singularity of the BH and the Penrose-Hawking singularity of the BH determine the spin and gravitational singularity of the BH. Inside the ergosurfaces, the BH singularities' backward inflow causes the vicinity's rate on feeding the BH. It makes the active galactic nuclei (AGN) a semi-closed system. The density pressure is released on threshold. During the mass exchange observed by energy momentum upon the AGN's open, the macroparticle composition of the BH changes with the galactic event. This causes the expansion rate of the galaxy and contraction rate of the BH. AGN types and their relative motions determine the expansion rate of the cosmic universe in a generalized quantitative thinking. The article concludes that BH spin is caused by the asymmetric motions of AGN in the BH system. A set of the nuclear resonance caused by BH and white hole (WH) oscillation is processed with the same set of data. (shrink)

In his classic book “the Foundations of Statistics” Savage developed a formal system of rational decision making. The system is based on (i) a set of possible states of the world, (ii) a set of consequences, (iii) a set of acts, which are functions from states to consequences, and (iv) a preference relation over the acts, which represents the preferences of an idealized rational agent. The goal and the culmination of the enterprise is a representation theorem: Any preference relation that (...) satisfies certain arguably acceptable postulates determines a (finitely additive) probability distribution over the states and a utility assignment to the consequences, such that the preferences among acts are determined by their expected utilities. Additional problematic assumptions are however required in Savage's proofs. First, there is a Boolean algebra of events (sets of states) which determines the richness of the set of acts. The probabilities are assigned to members of this algebra. Savage's proof requires that this be a σ-algebra (i.e., closed under infinite countable unions and intersections), which makes for an extremely rich preference relation. On Savage's view we should not require subjective probabilities to be σ-additive. He therefore finds the insistence on a σ-algebra peculiar and is unhappy with it. But he sees no way of avoiding it. Second, the assignment of utilities requires the constant act assumption: for every consequence there is a constant act, which produces that consequence in every state. This assumption is known to be highly counterintuitive. The present work contains two mathematical results. The first, and the more difficult one, shows that the σ-algebra assumption can be dropped. The second states that, as long as utilities are assigned to finite gambles only, the constant act assumption can be replaced by the more plausible and much weaker assumption that there are at least two non-equivalent constant acts. The second result also employs a novel way of deriving utilities in Savage-style systems -- without appealing to von Neumann-Morgenstern lotteries. The paper discusses the notion of “idealized agent" that underlies Savage's approach, and argues that the simplified system, which is adequate for all the actual purposes for which the system is designed, involves a more realistic notion of an idealized agent.

Liver transplantation (LT) activities during the COVID-19 pandemic have been curtailed in many countries. The impact of various policies restricting LT on outcomes of potential LT candidates is unclear. We studied all patients on the nationwide LT waitlists in Hong Kong and Singapore between January 2016 and May 2020. We used continuous time Markov chains to model the effects of different scenarios and varying durations of disruption on LT candidates.

Gilles Deleuze demonstrated the key role of flashback in dealing with the relationship between actual image and recollection-image when interpreting the temporality of images. He established two criteria for judging whether a flashback implies a recollection-image by stating that: (1) it serves as some kind of prompt in the narrative to make the viewer perceive that the scene has entered a flashback; (2) it relies on fate or forking time. But Deleuze also mentioned that, if the context or condition disappears, (...) the recollection-image represented by the flashback will lose its support, at which point, the pure recollection will also disappear. In this case, the actual image no longer forms a connection with the sensor-motor, but is suspended, which produces a fantasmatic effect. Bi Gan extends this suspension in his film “Long Day’s Journey into Night” by removing the character being referred to in the flashback, stripping it from figure and confining it in the voice-over. The film features an extreme use of several effects in the sensory-motor situations and the flashbacks, as described in Deleuze’s “Cinema 2: Time-Image,” namely recollection, dream, and falsification. Thus, the boundary between flashback and reality is completely broken. In addition, Bi Gan uses doppelgangers in the second part of the film to reconstruct the ambiguity of actual images and recollection-images in the first part, turning them into pure fantasies. This essay will analyze issues relating to the images and characters in “Long Day’s Journey into Night” and show how this film constitutes a typical case of recollection-images transformed into fantasies through the power of falsification.

Connecting research and production, art research represents a breaking of the barrier between creation and academia. However, there is also a contradiction contained in this kind of research deriving from its methods, since the process of art-based practice must, by its very nature, involve the subjectivity of the artist. I use my own studies as the research object to discuss this issue, and this article presents the problems I encountered during my artistic practice and research of ambiguous roles. This paper (...) has two main points of focus. First, I explore how the fallacy of self-referentiality is presented in paintings and films, and, second, I draw on my short film practice during my master’s study period to explain how the shots present a continuum in relation to the “absent one” and produce interface effects. However, the second point is not necessarily the result of the first one. This kind of connection and contradiction between practice and cognition in the process of art research is that I will analyse and discuss here. (shrink)

Upon Brexit & Trade War, the research took a supply-side analysis in macroeconomic paradigm for the purpose and cause of the actions. In the geopolitical competitions on crude oil resources between the allied powers & the Russian hegemony, the latter of which has effective control over P. R. China’s multilateral behaviors, the external research induced that trade war, either by complete information in intelligence or an unintended result, was a supply chain attack in prohibiting the antisatellite weapon supplies in the (...) Northern regions of mainland China in relation to Russia. Although no substantive change to international relations, the Trade War’s prohibitive effect on the high frequency trading in the monetary domain of CNY was observed, which had been the source of economic bubbles in the import-export control regime with centralized banking. The paper argues that by realism in economy & military strategy, trade war was ineffective in deterring the covert operations of the People’s Liberation Army by their territorial strategies and raises questions in humanitarianism in conflict situations. Moreover, with gross privacy breaches by mass surveillance in domain politics, totalitarianism with coercions, and counterfeit of drone strikes, traditional methods of threat elimination are rendered less pragmatic apart from the adversaries’ cyber security breaches. With the scientific approach, I offer an ecological paradigm with historic analysis of the Chinese military’s conducts in terms economics. The territorial methods of the PLA are contextualized into the ecological paradigm in regionalism & public administration. Electronic combats of the Chinese regime with the Great Firewall and Denial-of-Service attacks not only contribute to the diminishing natural freedoms of the population, but also transgress the fundamental right to health along with non-traditional nuclear threats to P.R.C. itself.

Traditional paradigm on marriage equality focused on a humanitarian appeal and was set as a path dependency model on marriage equality for the suppressed regions. However, such gender based focus has largely neglected the multilateral movements underlying the macro- political-economic structures that shaped law as a power political means. Consequentially, LGBTQI existence became marginalized from the public consciousness with structural realist state hierarchies that further undermines the fundamental freedoms of the LGBTQI popula- tion. This makes the question on LGBTQI equal (...) marriage from a simple humanitarian value based discourse to a macro-political-economy question. The article adopts the Maslow’s hier- archy of needs as the analytical framework on the developing country as the People’s Republic of China (PRC) in relation to multilateralism and global economy on the necessity to legalize LGBTQI marriage.
