Abstract

This article proposes, firstly, a general study of the ideological positioning of the Société scientifique de Bruxelles during the first forty years of its existence by means of a detailed reconstruction of its programme, and, secondly, a specific account of its situation within the alternative represented by the Intransigent and Progressive Catholic camps. In order to achieve this objective, it favours the motto of the Société and the figure of its second Secretary, namely Paul Mansion, basing itself primarily on a corpus of texts consisting of his annual reports and those of his predecessor, Father Carbonnelle. While taking particular care in identifying that which, following the Roman injunction in 1890, might have differentiated Mansion’s mandate from Carbonnelle’s, it offers to test the hypothesis that this difference lies, not only in a more favourable attitude towards neo-Thomism, but also in the transition from an intransigent apologetics to a more balanced apologetics.
