I like this quote from the reading we had to do on link (A). The quote is: There is no such thing as a moral or an immoral book. Books are well written, or badly written. That is all. – Oscar Wilde
I am really excited to read this because I like this quote a lot. Mainly because I agree with it. My Interpretation of it is as follows: I think Wilde is saying that as long you make a convincing argument in your favor, it doesn't matter if what you're saying is awful. Someone could write about war or death, but as long as they are taking the time to create a good story, the book should be good.
This quote specifically makes me think of people who always try to ban things because they are too "outrageous". Art for example is questioned sometimes as going to far. If you have an opinion about something and you share it with people, some may get offended and try to censor your opinion, or tell you to be quiet. I feel like Wilde is kind of saying it doesn't matter if people are getting offended or not, as long as you make a good point.
I also like the end of the quote where Wilde states that books are either well written or badly written because he doesn't leave room for the gray area. He just states that there are good books, and then there are bad books. I feel that with books that is the case. Most people either like a book or they don't. I personally separate books into two different categories. Books worth reading v.s. books that aren't worth reading.
question: are there books that are just okay that you would read if you had a choice to? Like if they weren't great but weren't awful do you think you would read them? especially when you have books out there that are great?
