I am currently writing a monograph on the Problems and Possibilities View of understanding (formerly Modal Understanding), a view of understanding as engagement and reflection in possible problem-solving activities. The view encompasses and unifies a wide array of instances of scientific understanding that evade the received view of understanding.<\/p>\n

Abstract<\/span>:<\/p>\n

Ecology was born out of a myriad of disciplines, including natural history, botany, biogeography, and more.\u00a0 The discipline has historically lacked unity and integration.\u00a0 The introduction of mathematical, physics-like models was intended to remedy this concern.\u00a0 Although theoretical ecological models have arguably had a significant impact on the field, they have been controversial.\u00a0 Concerns over the value of theoretical models arise from the realization that such idealized models largely misrepresent their target.\u00a0 What exactly are they good for? \u00a0In this chapter, I document the reasons why ecologists have valued theoretical models and investigate whether philosophical views of idealization in scientific modeling capture the ecologists\u2019 views. \u00a0I argue that the \u201cmodal modeling\u201d school of thought best accounts for theoretical modeling in ecology.<\/p>\n <\/div>\r\n \r\n

Abstract:<\/p>\n

The demise of the value-free ideal constitutes a threat to public trust in science. One proposal is that whenever making value judgments, scientists rely only on democratic values. Since the influence of democratic values on scientific claims and recommendations is legitimate, public trust in science is warranted. I challenge this proposal. Appealing to democratic values will not suffice to secure trust because of at least two obstacles: polarization and marginalization.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\r\n \r\n

Elgin is known to defend the view that scientific models contain \"felicitous falsehoods\". Models that are known to be inaccurate representations of the world are cognitively valuable, according to Elgin. Many, including Elgin herself, have interpreted this claim as leaning towards some form of anti-realism. In this paper, I will argue that this is a wrong-headed interpretation of Elgin's work: \"felicitous falsehoods\" do play a role into the cognitive value of inaccurate models, but that role is of instrumental value. Elgin does not hold the view that falsehoods provide scientific understanding in and of themselves: only that they facilitate epistemic access to the fundamental, even if partial, truths that are contained within the models. While falsehoods may be \"felicitous\" is that they help the process of \"exemplification\", the cognitive value of inaccurate models ultimately relies on their partial accuracy.<\/p>\n <\/div>\r\n \r\n

Introduction<\/p>\n

A great deal of scientific activity consists in constructing, comparing, and testing theories and associated models (TAMs) that are known to misrepresent the way the world actually is.i It is non controversial among scientists and even philosophers of science that these TAMs have epistemic value. The epistemic value of TAMs roughly comes in three kinds:<\/p>\n

(1) predictive power, (2) explanatory power, (3) heuristic power.<\/p>\n

First, notice that TAMs that misrepresent the world cannot be taken to provide explanations if one crucial characteristic of explanations is that the explanans statements be true, as it is the case in most accounts of explanation.ii Now, some of these TAMs have some predictive power, and that no doubt lends them some epistemic value. That said, most philosophers agree that this is not always the whole story, and for two main reasons. The first is that not all of the TAMs that are known to misrepresent the world are good at making predictions. The second is that most philosophers reject a purely instrumentalist view of science, and hope that TAMs that misrepresent the world can be conceived as affording some epistemic value beyond their mere predictive power.<\/p>\n

Whether we are considering the extreme cases of TAMs that lack both explanatory and predictive power, or whether we are looking for some epistemic value \u201cbeyond\u201d predictive or explanatory power, one option obviously remains open: TAMs that are known to misrepresent the world have heuristic power. They help scientists find theories and models that are either better at predicting, or better at explaining, or both.<\/p>\n

One crucial question that arises at this point, but that has not been addressed in the literature, is: how do they do that? What is it about these TAMs that gives us the cognitive ability to move forward? What cognitive achievement do they foster that renders progress possible? Understanding. More precisely, I submit that TAMs that misrepresent the world afford a form of scientific understanding of their target phenomena. This form of scientific understanding is a cognitive achievement that lies at the core of the various degrees of heuristic power that TAMs that misrepresent the world can have.<\/p>\n

In this paper, I will articulate a novel concept of scientific understanding. Roughly, the idea is that it consists in the ability to navigate some of the various possible worlds in which the phenomena arise. I dub this form of scientific understanding modal understanding. Section 2 will be devoted to developing this idea in more detail. Section 3 follows with answers to the most common objections that can be leveled against this \u201cmodal view\u201d of scientific understanding. It will also address how modal understanding relates to extant views of scientific understanding: the claim will be that modal understanding includes these as special cases, but also goes far beyond them.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/div>\r\n \r\n

Abstract<\/p>\n

The aim of this paper is to critically build on Justin Biddle and Anna Leuschner\u2019s characterization (2015) of epistemologically detrimental dissent (EDD) in the context of science. We argue that the presence of non-epistemic agendas and severe non-epistemic consequences are neither necessary nor sufficient conditions for EDD to obtain. We clarify their role by arguing that they are contingent enabling factors, not stable difference-makers, in the production of EDD. We maintain that two stable difference-makers are core to the production of EDD: production of skewed science and effective public dissemination.<\/p>\n <\/div>\r\n <\/div>\r\n\r\n\r\n\r\n <\/div>\n

Abstract:<\/p>\n

The aim of the paper is to show that understandability is not a basis for choosing between Bohm's theory and the Many-Worlds interpretation of standard quantum mechanics. Advocates on both sides assert that their preferred account is more understandable than the other. On that score, they are both right. The seeming inconsistency involved in this claim is dissolved when one realizes that they employ different notions of understandability. Moreover, understandability, on either notion, is not an overriding criterion of choice between competing accounts if our aim in developing physical theories is truth.<\/p>\n

Abstract<\/p>\n

In this paper, a modest version of the Semantic View is motivated as both tenable and potentially fruitful for philosophy of science. An analysis is proposed in which the Semantic View is given as characterized by three main claims. For each of these claims, a distinction is made between stronger and more modest interpretations. It is argued that the criticisms recently leveled against the Semantic View hold only under the stronger interpretations of these claims. However, if one only commits to the modest interpretation for all the claims, then the view obtained, which is called the Modest Semantic View, is tenable and fruitful.<\/p>\n <\/div>\r\n \r\n

Abstract<\/p>\n

Since he proved his theorem in 1982, Fine has been challenging the traditional interpretation of the experimental violation of the Bell Inequalities (BI). A natural interpretation of Fine's theorem is that it provides us with an alternative set of assumptions on which to place blame for the failure of the BI, and opens to a new interpretation of the violation of the BI. Fine has a stronger interpretation for his theorem. He claims that his result undermines the traditional interpretation in terms of local realism. The aim of this paper is to understand and to assess Fine's claim. We distinguish three different strategies that Fine uses in order to support his view. We show that none of these strategies is successful. Fine fails to prove that local realism is not at stake in the violation of the BI by quantum phenomena.<\/span><\/p>\n <\/div>\r\n \r\n

Abstract<\/p>\n

It so happens that classical physical theories can be interpreted as a representation of local interactions between systems with determinate properties. Orthodox quantum mechanics, which is one of our most experimentally well-confirmed theories, is notoriously resistant to being interpreted in terms of the above framework. Bell-type theorems and Bell-type experiments have made such an interpretation impossible. In the early sixties, John Bell demonstrated that any theory that represents its domain in terms of the above framework satisfies a set of inequalities, the so-called Bell inequalities. Experiments on quantum phenomena violate Bell-type inequalities. By a simple modus tollens, the upshot is that no theory that includes all the elements of the above framework can recover all statistical predictions of quantum mechanics. Philosophers have been trying to interpret this result, that is, to understand what the world might be like if it is true that physical interactions between systems are non-local, or that physical systems do not possess determinate properties. This line of thought found its climax in program of \u00d2experimental metaphysics\u00d3 that developed after the violation of Bell-type inequalities was observed. Experimental metaphysics consists in deriving metaphysical conclusions from the Bell-type experimental results. The mainstream interpretation within experimental metaphysics is that Bell-type experiments force us to accept the existence of a form of non-locality at the ontological level, but a form that we can consider benign because it is of a non-causal type. In my dissertation, I assess to what extent philosophical investigation can help us decide what the world is like on the basis of our best physical theories, from the point of view of the quantum domain and with an emphasis on Bell-type phenomena. My conclusions point to a more modest view on the possible achievements of philosophy of physics than the experimental metaphysics program would have us believe. In the first part of my dissertation, I investigate what role philosophy of physics can legitimately hope to play in the development and evaluation of various accounts of quantum phenomena. I claim that it is not the role of philosophy of physics to impose criteria of acceptability on physical theories, in addition to coherence and empirical adequacy. By contrast, I take in my dissertation that the legitimate role of philosophy of physics is to clearly determine what is imposed by the phenomena and our best theories from what is a matter of preference on the basis of the structural analysis of the phenomena and theories. In the second part of my dissertation, I turn to the more specific case of the interpretation of Bell-type theorems and Bell-type phenomena. I undertake a systematic examination of the mainstream interpretation. I show that the mainstream interpretation includes three claims, one about locality, another one about causation and a last one about holism. I utilize theories of locality and causation in order to assess these three claims. On the one hand, the upshot of my analysis is that the claim about locality can be supported by a rigorous theory of locality. On the other hand, no theory of probabilistic causation can support the claims of the mainstream interpretation about causation when it is construed as a strong program of experimental metaphysics yielding conclusions about the ontology of the world. That said, weakened versions of the mainstream interpretation, those that do without conclusions about the ontology of the world, can be made compatible with some theories of probabilistic causation. In particular, the mainstream interpretation can be rigorously supported if its claims are restricted to the empirical level.<\/span><\/p>\n <\/div>\r\n \r\n
