The so-called Buddhist momentarists, such as Dharmakīrti and his followers, defend the momentariness of all things. However, with equal force they also defend the persistence of all things, not just within a single lifetime but over an indefinite cycle of rebirth. Naturally, they have an interesting theory of persistence, according to which things persist without being self-identical over time. The theory is best presented in the Lokāyatāparīkṣā chapter of Śāntarakṣita’s Tattvasaṃgraha and Kamalaśīla’s Paṅjikā, as they clearly articulate the criteria of (...) persistence without identity. The purpose of this paper is to formulate a Buddhist theory of persistence through the analysis of these texts. Here is the basic formula: Things persist as series, which is constituted by momentary entities that are causally related as upādāna and upādeya. Upādāna causal relation is demarcated from other causal relations by the principle of changeability with temporal restriction, and the principle adopts further qualifications to accommodate complex cases and personal persistence. I have addressed a problem that contemporary physicalism might pose a threat to the Buddhist account of personal persistence, and argued that the problem can be evaded by regarding persons as psycho-physical entities rather than strictly non-physical. In its general outlook, the Buddhist theory of persistence is close to Theodore Sider’s stage theory in that persistence is a matter of distinct individuals standing in a special causal relationship. As regards personal persistence, the Buddhist has a stricter condition than Parfit’s IDM thesis, which states that psychological connectedness with any cause is what matters for survival. The Buddhist would say it is moral connectedness with a special cause called upādāna. (shrink)

The doctrine of radical impermanence expresses the temporal dimension of Buddhist metaphysics, especially in the philosophy of Dharmakīrti and his successors. Most straightforwardly, the doctrine says that everything that exists is momentary; we are not impermanent in the sense that we perish eventually, say when our brain ceases functioning, but rather we perish immediately upon conception. The person who begins to write this sentence and the person who completes it are, strictly speaking, different entities. However, there is a devastating problem (...) for the doctrine: How can any momentary entities be causally efficacious, and more particularly, given their extremely meager duration of existence, how might the momentarist explain the phenomena of cooperation among contemporaneous entities to occasion novel entities, such as seeds, soil, water and sunlight giving rise to sprouts? Even more difficult, can the momentarist offer such an explanation that does not undermine his negative claim that non-momentary things cannot exist? Śāntarakṣita and Ratnakīrti offer answers, but they both fail. By meticulously analyzing and evaluating their arguments, I identify the stumbling blocks of their arguments and show what needs to be done to save the doctrine of momentariness. (shrink)

“Atsumori” is a Noh play composed by master playwright Zeami sometime before 1423, featuring characters from the Tales of the Heike. Although popular to this day, the philosophical significance of the play remains underdeveloped and underappreciated. Prima facie, it features a ghost who is liberated thanks to the sincere prayer of the priest who killed him. Simplistic reading would yield simplistic understanding of the characters and their dynamism, and would fail to appreciate, for instance, the agency of the ghost or (...) the liberation of the priest. Accordingly, some regard the play as falling short of the highest aesthetic value, insofar as its protagonist fails to attain liberation through his own effort. Some even contend that the ulterior purpose of the play is to portray ghosts as powerless and desperate so that vanquishers need not fear vengeful ghosts. While it is possible that Zeami indeed held such ulterior intention and regarded it as second rank for the protagonist’s lack of agency, I shall present a different reading that would yield a richer appreciation of the characters and their dynamism. I do so by regarding the “friendship of dharma” that occurs at the culmination of the play as “existential communion” as presented in Tanabe Hajime’s later philosophy. That is, the play need not be read as a story about a living priest saving a dead warrior—it can be read as about two lost souls saving each other, through mutual acceptance, mutual sacrifice, and collaborative mediation of the Absolute. For this purpose, the paper first delineates Tanabe’s later philosophy with a focus on the idea of existential communion. Then it introduces “Atsumori” and discusses its philosophical significance. An impasse due to the scope of the play will be identified, which I call “the problem of epistemic authority,” and to fill the gap I will introduce and discuss another spin-off story featuring Atsumori. The paper intends to offer a philosophically richer reading of the play to invite readers to think deeply and creatively about Noh. (shrink)

According to the Buddhist doctrine of Two Truths, there are no persons in our final ontology, but there are persons in our conventional ontology. What does it mean to say that persons exist conventionally? The Ābhidharmikas say that ultimately there are psychophysical tropes, called dharmas, certain collections or combinations of which are conventionally taken to be persons. We would then ask: what kind of reality is conventional reality, and what is the metaphysical relation between conventional reality and ultimate reality as (...) pertains to persons?Recently there have been various attempts to understand Buddhist philosophy by using contemporary analytical methods and theories. Among the prominent scholars in this... (shrink)

Establishment of cell lineage identity from multipotent progenitors is controlled by cooperative actions of lineage‐specific and stably expressed transcription factors, combined with input from environmental signals. Lineage‐specific master transcription factors activate and repress gene expression by recruiting consistently expressed transcription factors and chromatin modifiers to their target loci. Recent technical advances in genome‐wide and multi‐omics analysis have shed light on unexpected mechanisms that underlie more complicated actions of transcription factors in cell fate decisions. In this review, we discuss functional dynamics (...) of stably expressed and continuously required factors, Notch and Runx family members, throughout developmental stages of early T cell development in the thymus. Pre‐ and post‐commitment stage‐specific transcription factors induce dynamic redeployment of Notch and Runx binding genomic regions. Thus, together with stage‐specific transcription factors, shared transcription factors across distinct developmental stages regulate acquisition of T lineage identity. (shrink)

In the preface to his new monograph, Tragic Beauty in Whitehead and Japanese Aesthetics, Steve Odin proposes to do two things: better understand Alfred N. Whitehead's "poetic vision of tragic beauty" through comparison with Japanese aesthetics, and thereby also suggest a "new religio-aesthetic vision of tragic beauty and its resolution in the supreme ecstasy of peace". He does more than that, though. Besides thoroughly discussing Whitehead's aesthetics throughout the latter's works, from An Enquiry Concerning the Principles of Natural Knowledge to (...) Modes of Thought, he enriches this aesthetics by discussing similar themes in American philosophy and literature, including Charles Peirce, John... (shrink)

We study the dynamics of a vortex in superfluid He4. This is carried out by deriving the effective Lagrangian for the center of the vortex by starting with the time-dependent Ginzburg-Landau formalism. From the resultant equation of motion for a vortex, we arrive at a novel aspect for the Magnus force which has long been known in fluid dynamics. This force has a geometric origin and is expected to occur in other form of condensates such as vortex excitations for quantum (...) Hall fluids or ferromagnets. We also consider the force of non geometric origin, the pinning force coming from the impurity. (shrink)

In this paper, we would present an overview of the recent studies on the role of diagram in mathematics. Traditionally, mathematicians and philosophers had thought that diagram should not be used in mathematical proofs, because relying on diagram would cause to various types of fallacies. But recently, some logicians and philosophers try to show that diagram has a legitimate place in proving mathematical theorems. We would review such trends of studies and provide some perspective from viewpoint of philosophy of mathematics.

Reasoning with conditionals is often thought to be non-monotonic, but there is no incompatibility with classical logic, and no need to formalise inference itself as probabilistic. When the addition of a new premise leads to abandonment of a previously compelling conclusion reached by modus ponens, for example, this is generally because it is hard to think of a model in which the conditional and the new premise are true.

This paper studies a fundamental mechanism by which conflicts between arguments are drawn from sentiments regarding acceptability of the arguments. Given sets of arguments, an inverse abstract argumentation problem seeks attack relations between arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in each of the attack relations. It is an inverse problem of the traditional problem we refer to as the forward abstract argumentation problem. Given an attack relation, the forward abstract argumentation (...) problem seeks sets of arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in the attack relation. We give a probabilistic model of argumentation-theoretic inference. It is a generative model formalising the process by which acceptability semantics interprets acceptability of arguments in a given attack relation. We show that it gives a broad view of solutions to the forward and inverse abstract argumentation problems. Specifically, solutions to the inverse and forward abstract argumentation problems are shown to be equivalent to a maximum likelihood estimate and maximum likelihood prediction, respectively, which are both available with the generative model. In addition, they are shown to be special cases of the posterior distribution and the evidence, respectively, which are both obtained by probabilistic inference on the generative model. We report an experiment result and application example of the generative model in the inverse problems. (shrink)

Previous research found that application of eyeshadow on the upper eyelids induces overestimation of eye size. The present study examined whether this eyeshadow illusion is dependent on or independent of viewpoint. We created a three-dimensional model of a female face and manipulated the presence/absence of eyeshadow and face orientation around the axis of yaw (Experiment 1) or pitch (Experiment 2) rotation. Using the staircase method, we measured perceived eye size for each face stimulus. Results showed that the eyeshadow illusion occurred (...) regardless of face orientation around axes of both yaw and pitch rotations. Crucially, the illusion’s magnitude did not vary across face orientations; lack of interaction between the illusion’s magnitude and face orientation was confirmed by small values of Bayes factors. These findings ruled out the hypothesis that eyeshadow serves as a depth cue and leads to overestimation of eye size due to size-distance scaling. Alternatively, the present findings suggest that the eyeshadow illusion can be well explained by the assimilation between the eyes and eyeshadow, which also facilitates assimilation between the eyes and eyebrows. Practical implications and the present findings’ generalizability are also discussed. (shrink)

This article constructs a static model of information acquisition when the agent does not know exactly what pieces of information he is missing. A representation of preferences over information channels and menus of lotteries is shown by adapting the model of unforeseen contingencies by Dekel et al. (Econometrica 69:891–934, 2001; Econometrica 75:591–600, 2007), which is an extension of Kreps (Econometrica 47:565–576, 1979; Economic analysis of markets and games: essays in honor of Frank Hahn, 1992). Also, characterisation of informativeness of an (...) information channel analogous to the one by Blackwell (Ann Math Stud 24:265–272, 1953) is examined in conjunction with the preference for flexibility by applying the structure of Shapley value.
