 One of the mottos of Praxe is "Dura Praxis Sed Praxis" (Latin for "the Praxe is harsh, but it is the Praxe", like "dura lex sed lex").These incidents have led to criticism against the Praxe, and the creation of student organizations against it.With the spread of higher education institutions throughout Portugal in the last quarter of the twentieth century, the concept of Praxe became different from university to university.
