Philip Joseph Hartog and Arthur Watson, 1911 Encyclopædia Britannica (1911)
“ In this public discussion the “disputation” of the middle ages survives in its least changed form. The literary theses required by French universities are, as a rule, volumes of several hundred pages, and more important in character even than the German Habilitationsschrift. The possession of the doctorate is a sine qua non for eligibility to a university chair, and to a lectureship in the university of Paris. In the faculty of sciences a candidate for the doctorate may submit two theses, or else submit one thesis and undergo an oral examination. ”
