This is an informative, if rather dry, book about the roles of women and men throughout history. It reads like a scientific study. It would be more interesting if it had some real-life examples added, and if it was organized in such a way that it really taught you something rather than just reporting on things. This was the textbook for an Intro to Women's Studies course I took.
That said, I did have an eye-opening experience about the truth of my own gender. I understand how social constructs based on patriarchal systems have informed the lives of women throughout history. I understand why men are so terrified of women having any power--it's because they fear that we will turn around and do to them what they've done to us for thousands of years.
We might well do that. Their fears may be founded. We used to be in "power" when the governing systems were largely matriarchal, but the men couldn't handle it and took over, and the only way they could do that was by force, through subjugation.
It's interesting to note that in today's modern world, however, there do still exist societies that are not based in patriarchy--societies that function as a matriarchy or as an equal community where every contribution is valued, regardless of how simple or complex. It gives us something to strive for.
