"The difference between men and women is inalienable. It is not a political fact, subject to cultural definition and redefinition, but a physical verity. We do truthfully experience our lives differently because our bodies are different. It is in what we do with our experience that we are the same. We feel, absorb and examine with the same intensity, and intense experience honestly examined informs the art of both sexes equally. ... The power of imagination illuminates all human lives in common."
