  1. Chemical reduction and quantum interpretation: A case for thomistic emergence.Ryan Miller - 2023 - Foundations of Chemistry 25 (3):405-417.
    The debate between ontological reductionists and emergentists in chemistry has revolved around quantum mechanics. What Franklin and Seifert (BJPS 2020) add to the long-running dispute is an attention to the measurement problem. They contend that all three realist interpretations of the quantum formalism capable of resolving the measurement problem also obviate any need for chemical emergence. I push their argument further, arguing that the realist interpretations of quantum mechanics actually subvert the basis for reduction as well, by undercutting the idea (...)

  • The Problem of Molecular Structure Just Is The Measurement Problem.Alexander Franklin & Vanessa Angela Seifert - forthcoming - The British Journal for the Philosophy of Science.
    Whether or not quantum physics can account for molecular structure is a matter of considerable controversy. Three of the problems raised in this regard are the problems of molecular structure. We argue that these problems are just special cases of the measurement problem of quantum mechanics: insofar as the measurement problem is solved, the problems of molecular structure are resolved as well. In addition, we explore one consequence of our argument: that claims about the reduction or emergence of molecular structure (...)

  • The strong emergence of molecular structure.Vanessa A. Seifert - 2020 - European Journal for Philosophy of Science 10 (3):1-25.
    One of the most plausible and widely discussed examples of strong emergence is molecular structure. The only detailed account of it, which has been very influential, is due to Robin Hendry and is formulated in terms of downward causation. This paper explains Hendry’s account of the strong emergence of molecular structure and argues that it is coherent only if one assumes a diachronic reflexive notion of downward causation. However, in the context of this notion of downward causation, the strong emergence (...)

    In the present paper we address the problem of optical isomerism embodied in the socalled “Hund’s paradox”, which points to the difficulty to account for chirality by means of quantum mechanics. In particular, we explain the answer to the problem proposed by the theory of decoherence. The purpose of this article is to challenge this answer on the basis of a conceptual analysis of the phenomenon of decoherence, that reveals the limitations of the theory of decoherence to solve the difficulties (...)

  • About the Concept of Molecular Structure.Olimpia Lombardi & Giovanni Villani - forthcoming - Foundations of Science:1-18.
    The concept of molecular structure is one of the most important concepts of chemistry. In fact, molecular structure is closely related to the concept of chemical substance and its set of properties, and it is the main factor in the explanation of reactivity. In fact, much of the behavior of substances is explained in terms of the structure of their component molecules. This may explain why people tend to take the notion of molecular structure for granted. However, the problem begins (...)

    El propósito del presente trabajo consiste en abordar la pregunta por la ontología de la química cuántica. Para ello nos concentraremos en el concepto de enlace químico desde la perspectiva de los dos enfoques a través de los cuales la ecuación de Schrödinger se aplica a los sistemas químicos moleculares: la teoría del enlace de valencia (EV) y la teoría del orbital molecular (OM). Sobre la base de la presentación de ambos enfoques y su comparación, señalaremos que, a pesar de (...)

    The modal-Hamiltonian interpretation belongs to the modal family of interpretations of quantum mechanics. By endowing the Hamiltonian with the role of selecting the subset of the definite-valued observables of the system, it accounts for ideal and non-ideal measurements, and also supplies a criterion to distinguish between reliable and non-reliable measurements in the non-ideal case. It can be reformulated in an explicitly invariant form, in terms of the Casimir operators of the Galilean group, and the compatibility of the MHI with the (...)

  • Is the problem of molecular structure just the quantum measurement problem?Sebastian Fortin & Olimpia Lombardi - 2021 - Foundations of Chemistry 23 (3):379-395.
    In a recent article entitled “The problem of molecular structure just is the measurement problem”, Alexander Franklin and Vanessa Seifert argue that insofar as the quantum measurement problem is solved, the problems of molecular structure are resolved as well. The purpose of the present article is to show that such a claim is too optimistic. Although the solution of the quantum measurement problem is relevant to how the problem of molecular structure is faced, such a solution is not sufficient to (...)

  • Linking chemistry with physics: arguments and counterarguments. [REVIEW]Olimpia Lombardi - 2013 - Foundations of Chemistry 16 (3):181-192.
    The many-faced relationship between chemistry and physics is one of the most discussed topics in the philosophy of chemistry. In his recent book Reducing Chemistry to Physics. Limits, Models, Consequences, Hinne Hettema conceives this relationship as a reduction link, and devotes his work to defend this position on the basis of a “naturalized” concept of reduction. In the present paper I critically review three kinds of issues stemming from Hettema’s argumentation: philosophical, scientific and methodological.

  • Why molecular structure cannot be strictly reduced to quantum mechanics.Juan Camilo Martínez González, Sebastian Fortin & Olimpia Lombardi - 2018 - Foundations of Chemistry 21 (1):31-45.
    Perhaps the hottest topic in the philosophy of chemistry is that of the relationship between chemistry and physics. The problem finds one of its main manifestations in the debate about the nature of molecular structure, given by the spatial arrangement of the nuclei in a molecule. The traditional strategy to address the problem is to consider chemical cases that challenge the definition of molecular structure in quantum–mechanical terms. Instead of taking that top-down strategy, in this paper we face the problem (...)

  • Wakeful consciousness as biological phenomenon : a teleological account.Tristan Kreetz - 2021 - Dissertation, University of Warwick
    This thesis develops an account of the nature of wakeful consciousness. Its principal suggestion is that wakeful consciousness is a biological phenomenon and should thus be placed in the context appropriate to biological phenomena. That context is the characterizing form of life of organisms. Once wakeful consciousness is assigned its place in this context, it emerges that wakeful consciousness is a teleological phenomenon, one that is to be understood as having the proper function of putting its bearer in touch with (...)

  • The problem of optical isomerism and the interpretation of quantum mechanics.Juan Camilo Martínez González - 2019 - Foundations of Chemistry 21 (1):97-107.
    When young Kant meditated upon the distinction between his right and left hands, he could not foresee that the problem of incongruent counterparts would revive in the twentieth century under a new form. In the early days of quantum chemistry, Friedrich Hund developed the so-called Hund paradox that arises from the supposed inability of quantum mechanics to account for the difference between enantiomers. In this paper, the paradox is expressed as a case of quantum measurement, stressing that decoherence does not (...)

    Usually within the context of computer simulations in quantum chemistry practices, there is a distinction between ab initio and semi-empirical methods. Related to this, a controversy within the scientific and philosophical communities came about regarding the superiority of the ab initio methods due to their theoretical rigor. In this article we re-evaluate the condition of the semi-empirical simulations in this area of research. We examine some of the aspects of this debate that have been considered in philosophy and provide additional (...)

  • On the Ontological Status of Molecular Structure: Is it Possible to Reconcile Molecular Chemistry with Quantum Mechanics?Sebastian Fortin, Martín Labarca & Olimpia Lombardi - 2022 - Foundations of Science 28 (2):709-725.
    According to classical molecular chemistry, molecules have a structure, that is, they are sets of atoms with a definite arrangements in space and held together by chemical bonds. The concept of molecular structure is central to modern chemical thought given its impressive predictive power. It is also a very useful concept in chemistry education, due to its role in the rationalization and visualization of microscopic phenomena. However, such a concept seems to find no place in the ontology described by quantum (...)
