When I was in high school and still under the jurisdiction of my parents, I heard my them discussing a book called "Under the Dome" by Stephen King. By the way my mother talked about it, I decided that this should be the next book I endeavor. When I asked her if she could give it to me to read...SHE REFUSED. I was like, "Um, excuse me? How can you not expect me to feel the need to partake of this goodness?" The grounds on which she refused to give me the book were that of inappropriate language, violence, and explicit sexual references.
I don't know why, but I just felt stupid. And I felt untrustworthy--like I couldn't be expected to be able to handle such a book with tact and maturity.
I believe the most important part of Areopagitica is that Milton argues the fact that we can't fully know what is good in this world if we are not give the chance to experience evil. No reason or agency is involved when we "choose" good over evil, simply because evil is not available to us by our mothers.
