  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.

    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 (...)

    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 (...)

    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.

    Connecting the Philosophy of Chemistry, Green Chemistry, and Moral Philosophy.Jean-Pierre Llored & Stéphane Sarrade - 2016 - 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 (...)

    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 (...)

    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 - 2016 - 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 (...)

    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 (...)
