What would happen if society was run by women? In Herland Charlotte Perkins Gilman imagines the result.      When three American men discover a community of women, living in perfect isolation in the Amazon, they decide there simply must be men somewhere. How could these women survive without man's knowledge, experience and strength, not to mention reproductive power? But what they have found is a civilisation free from disease, poverty and the weight of tradition. All alone, the women have created a society of calm and prosperity, a feminist utopia that dares to threaten the very concept of male superiority.
