In the figure of Francesc Xavier Llorens and Barba, a special halo surrounds him. An air between mythical and mysterious. The poet Joan Maragall, in 1901, proclaimed that of "[A Llorens i Barba] We venerate him So much and we know him so little". Later, Eugeni d'Ors would say that the philosopher of Vilafranca del Penedès was "for the new generations of Catalonia, a disturbing enigma". And a few years later, Rovira and Virgili would confirm that "there is a disproportion between the merits of Lorenzo and Barba and the knowledge they have of their life and their work". We believe that Llorens i Barba is a special name in the history of Catalan thought, but even today it is difficult for us to know exactly why. We have been in this situation for years. In summary, we know little, but we attribute a lot to it.
