Mary Wollstonecraft had grown up in a Spitalfields neighborhood in London. Wollstonecraft was a strong advocate of education for women. She herself had received little to no schooling when she was younger. She had taught herself and helped her sisters learn too, she even ran a school for a little while. Mary realized that she wanted to do more to help women be given the education that they need and deserve. She took a writing job in London, there she wrote her book A Serious Proposal to the Ladies where she asked "If all men are born free, how is it that all women are born slaves?" She had tried her best to see that women had the equal rights they deserved. Mary only lived from 1759 to 1797, she died when she was around 38. Mary had although had a daughter, Mary Wollstonecraft Shelly, who had went on in her mother's footsteps and wrote the classic novel Frankenstein.
Mary's thoughts challenged traditional beliefs in society by showing that women, like men, should be given their equal rights. That if you give a woman power over herself she can become great. That if you give a women the same rights that a man has she will prove to you that she has deserved them, not by sitting inside of a house all day cooking and cleaning. No, by going into the world and taking on jobs that were "designed for men". Mary had believed all of this and proved to society that knowledge is not an illness to a women's mind. No. Knowledge was power, knowledge was strength, knowledge was now a women's new life. One where she would be able to choose her own path. That is all Mary Wollstonecraft had wanted. For her, for her daughter, for all women out there.
"I do not wish women to have power over men; but over themselves." -Mary Wollstonecraft
This quote is saying that Mary didn't want women to have the power to control a mans life like how men and controlled their lives. She wanted women to be in charge on her own life, her own career path, and their owns decisions. She didn't want men making the decisions for them anymore.
