Philosophy is concerned with the meaning of human life, whether there is any such meaning and whether the human can be made an object of systematic study. Feminist philosophers have shown that the study of the meaning of human life cannot be done without a feminist worldview. Although high brow philosophical theory is a small, indeed elitist, field it is enormously influential in the long run, with lasting effects on the shape of everyday life. It is important that women infiltrate the field of 'high brow' theory and research. Feminism should not only concern itself with fair play/equality but also with changing the rules of the game. Not only politics, economics and science, but philosophy is very important in making and changing the rules. This paper examines feminist philosophy as a process that has influenced the worldview on women and is significant for a continued emancipation process in development cooperation.
