 Though Marty’s publications are almost exclusively concerned with linguistic matters, he lectured extensively in all areas of philosophy. Most of his literary remains have indeed been left unpublished. (See the catalogue in Bokhove and Raynaud 1990: 250–264.) The extensive correspondence with Brentano, most of which is also unpublished, is of course of great interest in connection with both of these philosophers. No ultimate assessment of Marty’s philosophical accomplishment will be possible until this material, including lecture notes, letters, and other manuscripts of interest, becomes accessible. A couple of years after his death, however, a work by him on space and time was published (Marty, [eds.] Eisenmeier et al. 1916c). This work gives us a rare look into Marty’s mature ontology. Though the resulting ontology of space and time is very much in line with Newtonian physics, it should be noted that Marty’s work on space and time was published posthumously in the same year in which Einstein’s celebrated paper on general relativity appeared (Einstein 1916). Unlike Brentano, he did not have the advantage of living long enough to have the chance of responding to the new concept of space-time that won the day in physics (Brentano, [ed.] Körner and Chisholm 1976: 29 f.). The work may nonetheless prove of to be of value at least insofar as it contains criticisms of the views of such outstanding philosophers as Leibniz, Berkeley, Kant, and Lotze.
