An illustrational form tells you through the intelligence immediately what the form is about, whereas a non-illustrational form works first upon sensation and then slowly leaks back into the fact.
The very concept of an Iranian university is an oxymoron. There are no free and open places of learning in that repressive theocracy. Dissenters are not given tenure; they are murdered, after first being tortured. Blasphemy, which is broadly defined, is punished. Gays are not only excluded from Iranian universities, but are imprisoned and killed.
