Famous quotes

  • « Now that virtually every career is an option for ambitious girls, it can no longer be considered regressive or reactionary to reintroduce discussion of marriage and motherhood to primary education. We certainly do not want to return to the simplistic duality of home economics classes for girls and wood shop for boys. »
    Camille Paglia
  • « Each of us has a very rich nature and can look at things objectively, from a distance, and at the same time can have something more personal to say about them. I am trying to look at the world, and at myself, from many different points of view. I think many poets have this duality. »
    Wislawa Szymborska
