La 'quaestio' di Stefano Langton 'Vtrum omnes uelint esse beati' (CAMB169), in Medioevo. Rivista di Storia della Filosofia Medievale, 39 (2014), pp. 173-215.

Stephen Langton's quaestio Vtrum omnes uelint esse beati is a hitherto unpublished testimony of the discussion at the turn of the 12th century on the topic "if every person wants to be happy". The quaestio is marked by a remarkable dialogical dynamism and offers us a text that is certainly significant in view of the degree of development of the literary genre of the quaestio. Moreover, making a comparison with other texts on the same topic of authors contemporary with Langton, the study shows the singular destiny of Langton's quaestio in the Tractatus de Sacramentis Ex Eius Summa De Sacramentis et Officiis Ecclesiae (composed between 1215 and 1220) by Guido de Orchelles († 1233). In Guido's tractatus 316 devoted to the topic Quid sit beatitudo, et utrum omnes uelint esse beati, Guido refers clearly to Langton's thought with the formula «nam haec fuit opinio domini Cantuariensis» and, as evidenced by this study, this is not an isolated case. This study therefore casts new light on the underestimated destiny and impact of Langton's quaestiones among the theological works written at the turn of the 12th century, and provides an opportunity for further research through which it will be possible to give careful consideration not only to the substantial influence of Langton's thought in many sections of Guido's Tractatus but also to adjudge what manuscript material may have been available toGuido di Orchelles or what was the nature of the academic relationship between him and Stephen Langton. In an Appendix, qu. CAMB169 - Vtrum omnes uelint esse beati is published.
