It is often argued that the indispensability of continuum models comes from their empirical adequacy despite their decoupling from the microscopic details of the modelled physical system. There is thus a commonly held misconception that temperature varying across a region of space or time can always be accurately represented as a continuous function. We discuss three inter-related cases of temperature modelling — in phase transitions, thermal boundary resistance and slip flows — and show that the continuum view is fallacious on (...) the ground that the microscopic details of a physical system are not necessarily decoupled from continuum models. We show how temperature discontinuities are present in both data (experiments and simulations) and phenomena (theory and models) and how discontinuum models of temperature variation may have greater empirical adequacy and explanatory power. The conclusions of our paper are: a) continuum idealisations are not indispensable to modelling physical phenomena and both continuous and discontinuous representations of phenomena work depending on the context; b) temperature is not necessarily a continuously defined function in our best scientific representations of the world; and c) that its continuity, where applicable, is a contingent matter. We also raise a question as to whether discontinuous representations should be considered truly de-idealised descriptions of physical phenomena. (shrink)

There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

A reasoned argument or tarka is essential for a wholesome vāda that aims at establishing the truth. A strong tarka constitutes of a number of elements including an anumāna based on a valid hetu. Several scholars, such as Dharmakīrti, Vasubandhu and Dignāga, have worked on theories for the establishment of a valid hetu to distinguish it from an invalid one. This paper aims to interpret Dignāga’s hetu-cakra, called the wheel of grounds, from a modern philosophical perspective by deconstructing it into (...) a simple probabilistic mathematical model. The objective is to understand how and why a vāda based on a probabilistically weaker hetu can degrade into a Jalpa or vitaṇḍā. To do so, the paper maps the concept of ‘Bounded Rationality’ onto the hetu-cakra. Bounded Rationality, an idea coined by the management thinker Herbert Simon, is often employed in understanding decision-making processes of rational agents. In the context of this paper, the concept would state that the prativādin and ālocaka (debater) may not hold unbounded information to back their pratijñā (proposition). The paper argues that within the probabilistically deconstructed hetu-cakra model, most people argue in the ‘Zone of Bounded Rationality’, and thus, the probability of a debate degrading into Jalpa or vitaṇḍā is high. -/- .

So-called ‘distinctively mathematical explanations’ (DMEs) are said to explain physical phenomena, not in terms of contingent causal laws, but rather in terms of mathematical necessities that constrain the physical system in question. Lange argues that the existence of four or more equilibrium positions of any double pendulum has a DME. Here we refute both Lange’s claim itself and a strengthened and extended version of the claim that would pertain to any n-tuple pendulum system on the ground that such explanations are (...) actually causal explanations in disguise and their associated modal conditionals are not general enough to explain the said features of such dynamical systems. We argue and show that if circumscribing the antecedent for a necessarily true conditional in such explanations involves making a causal analysis of the problem, then the resulting explanation is not distinctively mathematical or non-causal. Our argument generalises to other dynamical systems that may have purported DMEs analogous to the one proposed by Lange, and even to some other counterfactual accounts of non-causal explanation given by Reutlinger and Rice.

For the last two centuries the novel has been the predominant literary genre; but the generic identity of the novel is far from established. Attempts to define the novel have focussed on formal features of particular types of texts, with the result that definitions of “the” novel have merely canonized one or another of the innumerable novelistic manifestations—Bildungsroman, eighteenth-century English novels, novels of the kind George Eliot or Henry James or Marcel Proust or Feodor Dostoevsky wrote, etc. By basing themselves (...) upon such formal attributes, such definitions exclude a vast number of potential texts on essentially normative grounds. Further, the history of the novel has outgrown and contradicted those conceptions; no sooner than a theory has been formulated, the novel itself has moved forward, adapting to changing conditions and substituting for those formal properties a set of new ones, thus rendering the theories obsolete and revealing the inadequacy of formalist categories to define the genre. This predicament is certainly not unique to the theory of the novel but rather a necessary concomitant of any theoretical project; what makes any attempt to theorize about the novel particularly vulnerable is the genre's resistence to formalist analysis, its lack of precisely those organizing categories upon which a formalist theory of any genre can be built.

Polanyi’s philosophy of “man in thought,” by all appearances, chronologically and structurally, seems to be founded on his epistemology. Polanyi’s epistemology of tacit knowing as integration is teleological. By his “ontological equation,” he patterned comprehensive (and complex) entities as emergence on his epistemology. This forces him to make puzzling formulaic statements which land him in trouble with fellow scientists. The equation also lends itself to unwarranted problematic interpretations. The exploration leads me to suggest that Polanyi may be understood as a (...) “rational realist” who insisted on a tacit knowledge version of interactionist mode of mind-body relation. (shrink)

I examine social capital’s impact on financial reports. Based on the social capital literature, I predict that the quality of the financial reports is higher when a firm is headquartered in a region with high social capital. Consistent with this prediction, I find that the firms that are headquartered in this type of region in the USA have a lower probability of committing fraud by misrepresenting financial information. Further, I find that the firms in regions with high social capital have (...) lower levels of discretionary accruals and much more readable annual reports. (shrink)

Convolutional neural networks (CNNs) are increasingly widely used in psychology and neuroscience to predict how human minds and brains respond to visual images. Typically, CNNs represent these images using thousands of features that are learned through extensive training on image datasets. This raises a question: How many of these features are really needed to model human behavior? Here, we attempt to estimate the number of dimensions in CNN representations that are required to capture human psychological representations in two ways: (1) (...) directly, using human similarity judgments and (2) indirectly, in the context of categorization. In both cases, we find that low-dimensional projections of CNN representations are sufficient to predict human behavior. We show that these low-dimensional representations can be easily interpreted, providing further insight into how people represent visual information. A series of control studies indicate that these findings are not due to the size of the dataset we used and may be due to a high level of redundancy in the features appearing in CNN representations.

According to my interpretation, based on the entirety of Michael Polanyi's epistemological works, his theory of tacit knowing is conceived of as three models tied together by the central feature of Intellectual Passions as integrator. The models are progressively refined forms of his first conception of tacit knowing: ‘we know more than we can tell’. The three models are: the Gestalt-Perception Model based on the gestalt notion of part-whole relations, the Action-Guiding Model incorporating the phenomenological-existential notion of intentional action, and (...) the Semiotic Model, an abstract conception of action directed to meaning showing that tacit knowing has a ‘from-to structure’. In the Semiotic Model integration is named by the logical term ‘inference’. Polanyi's conception of reality and his theory of truth are introduced linked to the models, to show why his epistemology is not subjectivist and his theory of truth is not relativist. (shrink)
