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

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'.

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

Ethically and politically it is important to face up to the need for a universal perspective in our divided, multi-cultural, unequal and unjust world.

When it comes to deep and difficult ethical matters - such as the relation of an individual to God, or, I think, an individual caught up in the sublimity of a revolution then things are very different and the Kantian ethic is shown to be limited in its value.

However, within the limits of the human, it is important to recognise our common humanity. I think that a perspective based on common human needs has the most chance of being accepted and this does not depend on any particular metaphysical outlook.

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.
