What is Mary Wollstonecrafts claim in her arguement?

Wollstonecraft avers that her main argument is based on the simple principle that if woman is not educated to be the equal of man, the progress of knowledge and truth will be thwarted. Women must know why they are to be virtuous, and they must know the value of patriotism in order to instill such values in their children. Chastity ought to prevail, and women must move beyond merely being the objects of idolatry and desire.

Furthermore, if women possess reason just as men do, why are men the exclusive judges of freedom and happiness? Just as tyrants characteristically attempt to crush reason, men who would keep women ignorant are acting tyrannically. Tyranny will "undermine morality."
