【正确答案】正确答案： Didactic literature is a instructional literature in artistic form. Didactic literature presents philosophical, religious, moral, and scientific knowledge and ideas in various imaginative literary genres. In the period when there was no ideological separation between science and art, Didactic literature was a vital, naively integral form of contemplation and could be realized poetically. But as the specialized forms of scientific and philosophical exposition are distinguished, particularly in modern times, the artistic form of didactic literature become, in Hegel"s words, simply "ornamentation" , lending a "cheerful aspect to dry, serious instruction".
