Bound manuscript of 143 leaves, 9 of which are blank. The text is divided into chapters, and treats philosophical subjects including logic, metaphysics, and morality. The authorship is unknown, but may tentatively be attributed to Abraham Girard (1635-1693), from whose libary the manuscript originates. Bound in is a printed folio broadside, measuring 38.5 x 25 cm, with title "Theses ex Vniuersa Philosophia Selectae" and imprint "Has propugnabit Carolus Gassendus, diniensis, Lugduni, in aula Collegij SS. Trinitatis Soc. Iesu, die mensis Iulij 1652." It is conjectured that the manuscript is an abstract or lecture notes relating to this printed thesis, whose author, Carolus Gassendus, or Charles Gassendi, of Digne, was a contemporary, and perhaps a relative, of noted scientist and philosopher Pierre Gassendi.
