Formalism Texts - "Problems in the Study of Literature and Language" by Roman Jakobson and Yuri Tynyanov (1928)

Jakobson and Tynyanov talk about the laws governing the evolution of literature. It's written in bullet points. And it's super complicated. Got it? Got it.

Why is it so important to understand the laws that govern the evolution of literature, according to Jakobson and Tynyanov? How might that contribute to making Formalism a "science"?
