 When he was ten years old, Bolzano entered the Gymnasium (i.e., a kind of classical secondary school) of the Piarists in Prague, which he attended from 1791 to 1796. He subsequently began his “philosophical studies” at the University of Prague; they lasted three years, roughly corresponding to the higher level of high schools. Included in the “philosophical studies”, besides philosophy itself, were subjects such as history, languages, and biology, but above all also mathematics and physics. In the autumn of 1800 Bolzano began his study of theology at the University of Prague. At that time such a course of studies lasted four years; he finished it in the summer of 1804.
