what is the primary change in paradigm during the 18th century and the restoration?

this has something to do with literature if that helps any

some of the answers i might have include:

a. people started asking for rational instead of supernatural explanations

b. people stopped believing in god

c. the goverment recognized and encouraged religious tolerance

d. people stopped viewing literature as functional and instead viewed it as an unnecessary luxery

please just help me narrow it down and help me understand why the answer is the answer. thank you
