How does Fanny Burney use imagery in Evelina; or, The History of a Young Lady's Entrance into the World?

Alas, my child!-that innocence, the first, best gift of Heaven, should, of all others, be the blindest to its own danger,-the most exposed to treachery,-and the least able to defend itself, in a world where it is little known, less valued, and perpetually deceived!

In this quote, the author reveals Rev. Villar’s fear and love for Evelina, all while foreshadowing the impertinences she will suffer in London.
