The purpose of the satire is really to highlight the actions women wanted to be involved in in order to be considered intelligent.I think the author is telling women that they could think of many ways to show they deserve the admiration of others, mainly men, but all the same they will be seen as beautiful as the stars. The stars appear at night and then with the light of the day they cannot be seen.The persona in the poem is satirical but recognises that women have wits .However , this is a feature which is not always displayed or at least not all of the time.
