Deviation
One of Simone de Beauvoir's most interesting arguments is that, throughout history, women have been considered the deviation, the abnormality. Even Mary Wollstonecraft considers men to be the ideal which women should aspire to be. Simone de Beauvoir says this has held back women. It has maintained the perception that women are a deviation from the normal, that they are outsiders attempting to emulate normality. She says that, for feminism to move forward, they need to break out of this assumption.
