The main difficulty in this question is that it assumes that all of the approximately three billion women currently alive on earth think identically. That is actually not the case. There are, no doubt, many women who are primarily concerned about their looks as a source of potential strength. Fashion models or dancers or actresses, for example, use their physical appearance, as well as considerable professional skills, in their careers. Many other women work in fields such as engineering, politics, and finance, where reason is very important and appearance isn't. In western popular culture, there is still somewhat more emphasis on physical appearance for women than men, but in the wake of many years of feminism, such attitudes are far less common than they were 200 years ago, when Mary Wollstonecraft was writing.
