 The third type of order (iii) is the order of the end (finis) or the ends of the different sciences. Among the sciences, ethics is the first from this point of view, followed by the speculative sciences, and then the sciences of language. (According to this criterion, the order among the sciences of language is: logic, rhetoric, and grammar.) Speculative knowledge is ordered to ethics in the same way as truth is ordered to the supreme good (DOS 405; see Celano 2013, 340).
