(Lat., ‘the method of the studies’). The abbreviated name of the Jesuit scheme of studies issued in 1599. It was based on the best pedagogical theory of the time, and the success of Jesuit secondary education from the 16th to the 18th cent. was largely due to it. Later the term was used, until 1975, to denote the legislation on the philosophy and theology studied by Jesuit seminarians.
