Prelude: When Truth Encounters Us
The proposed text first appeared under the title PrĂ©lude. Quand la vĂ©ritĂ© nous donne rendez-vous as an introduction to Jean Greischâs volume, Rendez-vous avec la vĂ©ritĂ©. However, the vortex of metaphors that âtellâ the âtruthâ remains hardly reducible to a single âtheoryâ of âTruthâ. Over the centuries, what-is-âtrueâ has been said in many different ways, starting with the unsolvable opposition between the truth-fidelity of the Jewish tradition and the truth-disclosure/manifestation of classical Greek thought; passing through the truth-regulating, namely the truth-institution of Roman Latin culture, which âcontractualisesâ what is true; reaching up to the truths of the medieval Anglo-Saxon world (truth-correspondence, truth-coherence, truth-semantics, truth-consent, truth-interpretation). However, that the truth is not objectified does not mean that it is not an existential issue. On the contrary, this seems to be the lesson one can draw from the encounter between Pilate and Jesus: âI am the Truthâ. Nevertheless, it is possible to observe that some of the best pages from the history of philosophy are not those wondering about what the truth is, but rather those pages allowing their own authors and readers to be questioned by the â sometimes sudden â encounter with the disproportion of Truth. Therefore, not theorising but encountering the truth will be a fundamental question of philosophical research

Le « grand jeu de la vie » et ses enjeux : « religion » et « métaphysique »
La mĂ©taphore kantienne du « grand jeu de la vie », dont nous sommes tous partie prenante en tant que nous sommes citoyens du monde, obligĂ©s dâaffronter les quatre questions fondamentales : « Que puis-je savoir ? Que dois-je faire ? Que mâest-il permis dâespĂ©rer ? » et : « Quâest-ce que lâhomme ? » qui, dâaprĂšs Kant, rĂ©capitulent les grands intĂ©rĂȘts de la raison humaine dans une optique cosmopolitique, cette mĂ©taphore nous offre un excellent fil conducteur pour analyser les rapports complexes entre religion et raison philosophique. Contrairement Ă ce que prĂ©tend la vulgate contemporaine, nous nâavons pas encore fini dâexplorer la « fonction mĂ©ta » en ses quatre dimensions essentielles de la « trans-ascendance », de la « trans-descendance », de la « trans-passibilité » et de la « trans-possibilité » qui, mĂȘme si elles trouvent une expression diffĂ©rente dans le champ religieux et dans le champ de la rĂ©flexion philosophique, donnent infiniment Ă penser Ă la religion comme Ă la philosophie.Kantâs metaphor of the âbig game of lifeâ, to which all humans partake insofar as they are citizens of the world confronted with the four fundamental questions: âWhat can I know?, What ought I do?, What may I hope for?â and, last but not least: âWhat is man?â, which according to Kant summarize the major interests of Human reason in a cosmo-political perspective, offers an excellent thread for analyzing the complex relationships between Religion and Philosophy. As opposed to what many contemporary thinkers pretend, we have not yet finished pondering the âmeta-functionâ in its fourfold dimensions: âtrans-ascendanceâ, âtransdescendanceâ, âtrans-passibilityâ and âtrans-possibilityâ which, although they find a different expressions in the religious field and in the field of philosophical thought, invites to rethink both religion and philosophy.La metĂĄfora kantiana del âgran juego de la vidaâ, en la que todos somos partĂcipes interesados en tanto que somos ciudadanos del mundo, obligados a enfrentar las cuatro preguntas fundamentales: âÂżQuĂ© puedo saber?â, âÂżQuĂ© debo hacer?â, âÂżQuĂ© me estĂĄ permitido esperar?â, y âÂżquĂ© es el hombre?â, las cuales, segĂșn Kant, recapitulan los grandes intereses de la razĂłn humana desde una Ăłptica cosmopolĂtica, nos ofrece un excelente hilo conductor para analizar las relaciones complejas entre religiĂłn y razĂłn filosĂłfica. Contrariamente a lo que pretende la vulgata contemporĂĄnea, no tenemos que vĂ©rnosla aĂșn con la âfunciĂłn metaâ en sus cuatro dimensiones esenciales de la âtrans-ascendenciaâ, de la âtrans-descendenciaâ, de la âtrans-pasabilidadâ y de la âtransposibilidadâ que, aĂșn si encuentran una expresiĂłn diferente en el campo religioso y en el campo de la reflexiĂłn filosĂłfica, dan mucho que pensar a la religiĂłn y a la filosofĂa

Structural information inference from lanthanoid complexing systems: photoluminescence studies on isolated ions
The application of lanthanoid complexes ranges from photovoltaics and light-emitting diodes to quantum memories and biological assays. Rationalization of their design requires a thorough understanding of intramolecular processes such as energy transfer, charge transfer, and non-radiative decay involving their subunits. Characterization of the excited states of such complexes considerably benefits from mass spectrometric methods since the associated optical transitions and processes are strongly affected by stoichiometry, symmetry, and overall charge state. We report herein spectroscopic measurements on ensembles of ions trapped in the gas phase and soft-landed in neon matrices. Their interpretation is considerably facilitated by direct comparison with computations.\newline
The combination of energy- and time-resolved measurements on isolated species with density functional as well as ligand-field and Franck-Condon computations enables us to infer structural as well as dynamical information about the species studied. The approach is first illustrated for sets of model lanthanoid complexes whose structure and electronic properties are systematically varied via the substitution of one component (lanthanoid or alkali,alkali-earth ion): (i) systematic dependence of ligand-centered phosphorescence on the lanthanoid(III) promotion energy and its impact on sensitization, and (ii) structural changes induced by the substitution of alkali or alkali-earth ions in relation with structures inferred using ion mobility spectroscopy. The temperature dependence of sensitization is briefly discussed. The focus is then shifted to measurements involving europium complexes with doxycycline an antibiotic of the tetracycline family. Besides discussing the complexesâ structural and electronic features, we report on their use to monitor enzymatic processes involving hydrogen peroxide or biologically relevant molecules such as adenosine triphosphate (ATP)
A litmus test for the balanced description of dispersion interactions and coordination chemistry of lanthanoids
The influence of long-range interactions on the structure of complexes of Eu(III) with four 9-hydroxy-phenalen-1-one ligands (HPLN) and one alkaline earth metal dication [Eu(PLN)AE] (AE: Mg, Ca, Sr, and Ba) is analyzed. Through the [Eu(PLN)Ca] complex, which is a charged complex with two metalsâone of them a lanthanoidâand with four relatively fluxional Ï-ligands, the difficulties of describing such systems are identified. The inclusion of the D3(BJ) or D4 corrections to different density functionals introduces significant changes in the structure, which are shown to stem from the interaction between pairs of PLN ligands. This interaction is studied further with a variety of density functionals, wave-function based methods, and by means of the random phase approximation. By comparing the computed results with those from experimental evidence of gas-phase photoluminescence and ion mobility measurements it is concluded that the inclusion of dispersion corrections does not always yield structures that are in agreement with the experimental findings
