Antony Marty (October 18, 1847–October 1, 1914) was a philosopher of language, psychologist, and ontologist. He was born in Schwyz, Switzerland in a very large family and baptized as a Catholic with the full name of ‘Martin Anton Maurus Marty’. His oldest brother went into the priesthood and became a missionary to the Sioux in North America. Though Marty himself was ordained, he left the priesthood shortly after Brentano had done so (in 1873, a few years after the declaration of papal infallibility) and pursued an academic career instead. He died in Prague, at that time a city that belonged within the Austro-Hungarian Empire and where he had been professor at the German-speaking division of the Ferdinand Charles University for most of his academic career.
Marty’s philosophical work is distinct especially as an application of Brentano’s descriptive psychology to the study of language in opposition to many of the prominent currents in linguistics and philosophy of language during his time. These were in many cases much more historical rather than psychological in character, but also often based on psychological theories wherein intentionality was not fully or hardly at all thematized as it was in Brentanian psychology. Marty’s philosophy of language is accordingly outstanding as a reflection on linguistic phenomena as essentially intentional.
