Was Kant Sexist?

     For my book review, I read Observations on the Feeling of the Beautiful and Sublime by Immanuel Kant. In Section Three of the book, entitled "Of the Distinction of the Beautiful and Sublime in the Interrelations of the Two Sexes," I noticed something interesting. At one point, Kant stated:
          A woman who has a head full of Greek, like Mme Dacier, or carries on fundamental controversies
          about mechanics, like the Marquise de Châtelet, might as well even have a beard; for perhaps that
          would express more obviously the mien of profundity for which she strives. (Kant 78)

In my opinion, this remark comes off as a bit sexist. However, I am curious to see if anyone agrees or disagrees with me.
