Modal Approaches in Metaphysics and Quantum Mechanics

Vladislav Terekhovich

Published Sep 22, 2019• 1 citation

Abstract

Some interpretations of quantum mechanics use notions of possible states and possible trajectories. I investigate how this modal approach correlates with several metaphysical conceptions of a transition from potential to actual existence. The comparison is based on a discussion in contemporary analytical metaphysics of modality. I also consider an analogy between Leibniz's theory of the possibilities striving towards existence, wave mechanics of Schrodinger, and Feynman path integral.

The contextual and modal character of quantum mechanics : a formal and philosophical analysis in the foundations of physics

Christian DE RONDE

This doctoral dissertation contains four main elements: \n \n1. We put forward an interpretational map of quantum mechanics in general and of the modal interpretation in particular based on metaphysical and anti-metaphysical stances. \n \n2. In contraposition to what we characterize as the anti-metaphysical and classical metaphysical \n \nstances we collect arguments in favor of a constructive metaphysical stance. \n \n3. We analyze the meaning of contextuality and possibility in quantum theory in general, and in the modal interpretation in particular. \n \n4. Finally, we end up with a proposal for the development of a possible constructive metaphysical scheme based on the notion of potentiality. \n \nAlthough some of these problems are well known in the literature we attempt to cast new light on the discussion through the analysis of the concepts involved and their relation to the formalism. We attempt to make explicit the tension in between the theoretical conditions and the conceptual structure of the theory, in order to discuss and disclose the metaphysical ideas involved within the different interpretational problems of quantum mechanics. We believe that this analysis can help us to understand much of the implicit background of such theoretical conditions. \n \nThe dissertation centers itself on the modal and contextual character of quantum mechanics. On the one hand, we discuss the contextual character of quantum possibility through the development of a Modal Kochen-Specker theorem, and on the other hand, we analyze the contextual character of quantum correlations through the distinction of properties. In the last part we discuss some more speculative ideas related to the possible metaphysical developments of quantum mechanics based on the notion of potentiality.

For and Against Metaphysics in the Modal Interpretation of Quantum Mechancis

Christian DE RONDE

In this paper we discuss the relation of quantum theory to the problem of metaphysics.Based on metaphysical and anti-metaphysical stances, we put forward an 'interpretational map' of quantum mechanics in general and of the modal interpretation in particular.Thus, within the modal interpretation, we distinguish between: Modal Interpretations (which start from) the Mathematical Formalism (MIMF) and Modal Interpretations (which start from) Metaphysical Principles (MIMP).Finally, we argue for a middle path in between metaphysical principles and the formal conditions imposed on quantum mechanics.

The Nature of Contingency: Quantum Physics as Modal Realism

Alastair Wilson

Contingency is everywhere, but what is it? This book defends a radical new theory of contingency as a physical phenomenon. Drawing on the many-worlds approach to quantum theory and on cutting-edge metaphysics and philosophy of science, it argues that quantum theories are best understood as telling us about the space of genuine possibilities rather than as telling us solely about actuality. When quantum physics is taken seriously in the way first proposed by Hugh Everett III, it provides the resources for a new systematic metaphysical framework encompassing possibility, necessity, actuality, chance, counterfactuals and a host of related modal notions. The framework is a modal realist one, in the tradition of David Lewis: all genuine possibilities are on a par, and the actual world is simply the one that we ourselves inhabit. It departs from Lewisian modal realism in that quantum possible worlds are not philosophical posits but scientific discoveries. Contingency and other modal notions have often been seen as beyond the limits of science. Rationalist metaphysicians argue that the metaphysics of modality is strictly prior to any scientific investigation: metaphysics establishes which worlds are possible, and physics merely checks which of these worlds is actual. Naturalistic metaphysicians respond that science may discover new possibilities and new impossibilities. This book’s quantum theory of contingency takes naturalistic metaphysics one step further, allowing that science may discover what it is to be possible. As electromagnetism revealed the nature of light, as acoustics revealed the nature of sound, as statistical mechanics revealed the nature of heat, so quantum physics reveals the nature of contingency.

Many worlds and modality in the interpretation of quantum mechanics: An algebraic approach

Graciela Domenech, Héctor Freytes, Christian DE RONDE

Many world interpretations (MWIs) of quantum mechanics avoid the measurement problem by considering every term in the quantum superposition as actual. A seemingly opposed solution is proposed by modal interpretations (MIs) which state that quantum mechanics does not provide an account of what “actually is the case,” but rather deals with what “might be the case,” i.e., with possibilities. In this paper we provide an algebraic framework which allows us to analyze in depth the modal aspects of MWI. Within our general formal scheme we also provide a formal comparison between MWI and MI, in particular, we provide a formal understanding of why—even though both interpretations share the same formal structure—MI fall pray of Kochen–Specker-type contradictions while MWI escape them.

Quantum Mechanics, Chance and Modality

Dennis Dieks

The thesis of this article is simple: even if it is accepted that quantum mechanics is a fundamentally probabilistic theory, this provides us with no special reason to believe in "chances" in the sense of objectively existing factors that are responsible for the relative frequencies we encounter in experiments.More in general, quantum mechanics gives us no special reason to believe in the actual existence of modalities.We may intuitively be inclined to believe in chances as a kind of causes, just as in classical mechanics we are inclined to think of forces as causal powers that produce accelerations.It might even be the case that intuitions of this kind can be developed into a coherent metaphysical scheme (something which has yet to be done, I think).But as I shall argue, a sober Humean perspective on quantum mechanics is certainly possible as well, and has much to recommend it.In short, the thesis of the present paper is that for a Humean, quantum mechanics introduces no reasons to abandon his position.

The Contextual Character of Modal Interpretations of Quantum Mechanics

Graciela Domenech, Héctor Freytes, Christian DE RONDE

In this article we discuss the contextual character of quantum mechanics in the framework of modal interpretations. We investigate its historical origin and relate contemporary modal interpretations to those proposed by M. Born and W. Heisenberg. We present then a general characterization of what we consider to be a modal interpretation. Following previous papers in which we have introduced modalities in the Kochen-Specker theorem, we investigate the consequences of these theorems in relation to the modal interpretations of quantum mechanics.
