  1. Mereologies as the grammars of chemical discourses.Rom Harré & Jean-Pierre Llored - 2011 - Foundations of Chemistry 13 (1):63-76.
    Mereology is the logic of part—whole concepts as they are used in many different contexts. The old chemical metaphysics of atoms and molecules seems to fit classical mereology very well. However, when functional attributes are added to part specifications and quantum mechanical considerations are also added, the rules of classical mereology are breached in chemical discourses. A set theoretical alternative mereology is also found wanting. Molecular orbital theory requires a metaphysics of affordances that also stands outside classical mereology.

    Connecting the philosophy of chemistry, green chemistry, and moral philosophy.Jean-Pierre Llored & Stéphane Sarrade - 2015 - Foundations of Chemistry 18 (2):125-152.
    This paper aims to connect philosophy of chemistry, green chemistry, and moral philosophy. We first characterize chemistry by underlining how chemists: co-define chemical bodies, operations, and transformations; always refer to active and context-sensitive bodies to explain the reactions under study; and develop strategies that require and intertwine with a molecular whole, its parts, and the surroundings at the same time within an explanation. We will then point out how green chemists are transforming their current activities in order to act upon (...)

    Emergence and quantum chemistry.Jean-Pierre Llored - 2012 - Foundations of Chemistry 14 (3):245-274.
    This paper first queries what type of concept of emergence, if any, could be connected with the different chemical activities subsumed under the label ‘quantum chemistry’. In line with Roald Hoffmann, we propose a ‘rotation to research laboratory’ in order to point out how practitioners hold a molecular whole, its parts, and the surroundings together within their various methods when exploring chemical transformation. We then identify some requisite contents that a concept of emergence must incorporate in order to be coherent (...)

  5. Molecules and mereology.Rom Harré & Jean-Pierre Llored - 2013 - Foundations of Chemistry 15 (2):127-144.
    This paper widens the scope of our previous paper (Harré and Llored in Found Chem 13:63–76, 2011) by scrutinizing how whole/parts relations are involved in the study of molecules. In doing so, we point out two mereological fallacies which endanger both philosophical and chemical inferences. We also further explore how the concept of affordance is related to our mereological investigation. We then refer to quantum chemistry in order to pave the way for a new mereological approach for chemistry.

    Chemistry and Measurement: Some Philosophical Lessons.Jean-Pierre Llored - 2021 - Perspectives on Science 29 (6):782-801.
    How do chemists assign numbers to chemicals properties? What do these numbers refer to? To answer these questions, we will first point out both the context-dependence of chemicals and the epistemic limitations of chemistry. We will then investigate how chemists use various procedures to stabilize measurements and how they use mixtures of samples as “references” in order to determine the amount of different chemicals in a sample. This study will enable us to query how it is possible for chemists to (...)

    Investigating Consistencies, Inconsistencies, and the Meaning of the Ceteris Paribus Clause in Chemistry.Jean-Pierre Llored - 2017 - Humana Mente 10 (32):53-74.
    Chemists do not aim at testing preconceptions or theoretical hypotheses only; they first and foremost produce and determine the object of chemical investigation: they learn through making. They never cease to create and stabilize heterogeneous devices, methods, models, and theories in order to act upon the world. Chemical bodies cannot be studied in isolation; their properties constitutively depend on what surrounds and acts upon them. Starting from the specificity of chemical practices, this paper investigates the meaning of consistency, inconsistency, and (...)

    How to investigate the underpinnings of sciences? The case of the element chlorine.Sarah Hijmans & Jean-Pierre Llored - 2020 - Foundations of Chemistry 22 (3):447-456.
    In recent publications, Harré and Llored Challenges of cultural psychology, Routledge, London, pp 189–206, 2018a; Philosophy, 93:167–186, 2018b; The analysis of practices, Cambridge Scholars Publishing, Newcastle upon Tyne, 2019) take the role of philosophy of science as a digging out of the ‘hinges’, that are the tacit elements of a discipline. In this perspective, the philosophy of chemistry consists, at least partly, in making explicit the hinges on which chemistry turns and in examining their origins and logical status. In this (...)

    Towards a Practical Form of Epistemology: The Case of Green Chemistry.Jean-Pierre Llored - 2012 - Studia Philosophica Estonica 5 (2):36-60.
    This paper explores how chemists are transforming their own current background in order to act upon the world without jeopardizing life. In this respect, I will envisage science as both a system of propositions and a set of engaged practices. The scrutiny of chemical innovations will allow me to query the concepts of paradigm and that of scientific community . In doing so, I will connect the philosophy of science with the philosophy of technology so as to think about our (...)

    Whole-Parts Strategies in Quantum Chemistry: Some Philosophical and Mereological Lessons.Jean-Pierre Llored - 2014 - Hyle: International Journal for Philosophy of Chemistry 20 (1):141-163.
    Philosophers mainly refer to quantum chemistry in order to address questions about the reducibility or autonomy of chemistry relative to quantum physics, and to argue for or against ontological emergence. To make their point, they scrutinize quantum approximations and formalisms as if they were independent of the questions at stake. This paper proposes a return to history and to the laboratory so as to emphasize how quantum chemists never cease to negotiate the relationships between a molecule, its parts, and its (...)

    How Philosophy of Nature Needs Philosophy of Chemistry.Jean-Pierre Llored - 2016 - Philosophica: International Journal for the History of Philosophy 24 (47):93-108.
    This paper aims to highlight how the philosophy of chemistry could be of help for rethinking Nature today. To do so, we will point out: the co-definition of chemical relations and chemical relata within chemical activities; the constitutive role of the modes of intervention in the definition, always open and provisional, of “active” chemical bodies; and the mutual dependence of the levels of organization in chemistry. We will insist on the way chemists tailor networks of interdependencies within which chemical bodies (...)

    Kostas Gavroglu and Ana Simões: Neither physics nor chemistry. A history of quantum chemistry: The MIT Press, Cambridge, MA & London, 2012, 351 pp. [ISBN-10: 0262016184; ISBN-13: 9780262016186].Jean-Pierre Llored - 2014 - Foundations of Chemistry 18 (1):81-84.
    In line with their previous studies dedicated to quantum chemistry (Gavroglu and Simões 1994, 2000; Simões and Gavroglu 1997, 2001), the last joint publication by Kostas Gavroglu and Ana Simões provides the readers not only with a fine-grained, rigorous, and highly valuable book on the history of science but also with stimulating epistemological insights about the way ‘in-between’ disciplines, to use the authors’ turn of phrase, emerge from the convergence of diverging ‘styles’ of research and heterogeneous practices. To make their (...)

    The Philosophy of Chemistry: Practices, Methodologies, and Concepts.Jean-Pierre Llored (ed.) - 2013 - Cambridge Scholars Press.
    This volume connects chemistry and philosophy in order to face questions raised by chemistry in our present world. The idea is first to develop a kind of philosophy of chemistry which is deeply rooted in the exploration of chemical activities. We thus work in close contact with chemists. Following this line of reasoning, the first part of the book encourages current chemists to describe their workaday practices while insisting on the importance of attending to methodological, metrological, philosophical, and epistemological questions (...)

    Mereology and quantum chemistry: the approximation of molecular orbital. [REVIEW]Jean-Pierre Llored - 2010 - Foundations of Chemistry 12 (3):203-221.
    Mulliken proposed an Aufbauprinzip for the molecules on the basis of molecular spectroscopy while establishing, point by point, his concept of molecular orbit. It is the concept of electronic state which becomes the lever for his attribution of electronic configurations to a molecule. In 1932, the concept of orbit was transmuted into that of the molecular orbital to integrate the probabilistic approach of Born and to achieve quantitative accuracy. On the basis of the quantum works of Hund, Wigner, Lennard-Jones and (...)
