Beyond Good and Evil: Prelude to a Philosophy for the Future Book

I recommend, but with a warning. The vast majority of people will not get much out of this book. Filtering through these reviews, I see a lot of people who are clearly not meant for Nietzsche's writing. They tend to fall under a couple of categories
1) Easily Offended: when Nietzsche says something they find offensive, they are turned off reading the book. Nietzsche will offend you. However...
2) People who make a superficial reading and criticize accordingly. This follows from 1. Those who are initially offended always seek more ways to find themselves offended, and read Nietzsche like he was an idiot. Seek and ye shall find. If you want to read Nietzsche as such, he will give you plenty of material.
3) Those who want a clear list of premises and a linear argument. Nietzsche's thought is ordered. Much of this book develops thematically though, and not through premises. Some won't like that style, but there is a reason Nietzsche is renowned for his writing. This leads into...
4) People who don't think like Nietzsche. Because Nietzsche doesn't write straight treatises, you need to understand the lines of thought he proposes. Those who don't see those lines commonly write negative reviews complaining about how Nietzsche doesn't "prove his assertions". This leads to the final....
5) People who don't understand Nietzsche's project. This also has a lot to do with Nietzsche's style. This book is not supposed to give formally structured arguments. If you read Nietzsche according to some rubric you deem appropriate, you miss his point entirely.

Suggestions:
1. Just because something is wrong, it doesn't mean it lacks value. Stop reading Nietzsche like a science textbook filled with facts. Also, stop reading him like he is attempting to make a logically impenetrable argument in defense of a single thesis.
2. Look for the nuances, and appreciate them. Was Nietzsche a misogynist? Yes. He was also a very thoughtful misogynist whose writings on women actually do hold some value. He contextualizes these passage in the introduction to that section, where he explicitly recognizes his own prejudices as a personal stupidity. Read in that light, his comments are actually quite interesting. Secondly, he writes of the condition of "woman" in many passages, not "woman" as a fixed essence. The two are quite distinct. Much of what is offensive at first glance is actually passing judgment upon the character of humanity at large. When he argues, for example, that men had good reason for not allowing women to speak in church, he isn't making an argument that women are inferior to men. Rather, it is an argument based upon the equality of sexes. He doesn't want to give women the chance to prove themselves just as foolish as men. Behind their silence, Nietzsche notes, they are untainted by their "real" nature. Whether or not you take Nietzsche to be making a serious suggestion here, he is obviously not making a offhand misogynistic comment. In the same way we don't dismiss the Greeks on the grounds of their caste based society, it is silly to dismiss Nietzsche for a misogyny he acknowledges as his own weakness.
3. Nietzsche writes to spark a line of thoughts and questions, not to answer all of them. Tons of the complaints start from the presupposition that Nietzsche should write according to a goal they have established for him. If you don't understand Nietzsche's goals, don't fashion your own for him.
4. It is entirely possible that you are not the type of person who can identify with Nietzsche on any sort of personal level. His work isn't meant to be read in a removed way. If you don't understand his criticisms on a personal and emotional level (not just logically), this book may not be for you. Just don't make the leap and call him unintelligent or a loose cannon. Most of the times, it is his readers that are bringing excessive emotion to the book, and their emotional reading that renders it obtuse.
