Whatever the universal perspective one adopts, it is important to recognise that some form of universalism is politically and ethically necessary.

From a political perspective, it is important to uphold certain universal principles so that, for example, you can condemn both Islamist forms of violence and injustice as well as forms of violence and injustice from other groups - some superpowers, for example, or the English Defence League, as other examples.

If there are more than two sexes, then so be it and, of course, the assumption that there are two helps shape, as many have argued, the binary logic that underpins much of the history of western philosophy.

Whatever the universal perspective one adopts, it is important to recognise that some form of universalism is politically and ethically necessary.

The universal basis for the categorisation 'woman' will, no doubt, be constantly shifting but it is important not to deny it's existence altogether. There is a partly biological basis for this identification. The 'nature' of woman may be conceptualised in the early Greek sense of a force or a power, in its turn shaped by forces outside it, rather than in terms of some set of properties.

I believe that a concept that may have some flaws is nonetheless important as a tool to critique abuses on all sides of the political spectrum. In the end, I think that a more useful 'universal' concept than that of a 'right', though, is a 'need'.
