I actually liked this one. I found the concept of the theory of forms and the idea of an ideal society intriguing. I'd recomend it.

Not the worst. It contains an idea that may be the origin of the movie the matrix. Just don't think about it too much and you should be ok.

I didn't get past part seven (a trend that followed me through the rest of my philosophy books). I didn't really like it much and didn't want to try to.

Not bad political philosophy. A bit lengthly though. I didn't get through much of it really.

Got through the majority of it. Short and not the most interesting.

I wouldn't suggest reading it. Nietzsche did actually go insane, and I is clear from reading just a few pages that he was an antisemetic. I consider this the point where philosophy becomes insane.
