It is of note that for a long time moral nihilism was a kind of unquestioned default position in analytic moral philosophy.

We own ourselves. This is the core of a libertarian theory of rights. But on this theory, while we are at liberty to kill ourselves (regardless of the consequences of others), we are not allowed to kill others, not even if this means that there we be fewer murders in the future, totally speaking.

Even where people in different cultures agree they may all have gone wrong.

These theories, deontology, the moral rights theory, and utilitarianism, contradict one another. Moreover, they give conflicting (inconsistent) recommendations. It is hence not possible to hold them together, in a pursuit of moral truth.

It is obvious, I think, that national democracy withers. This has to do with globalisation.

It is of note that even if utilitarianism has proved to be superior to deontology and the libertarian moral rights theory in the area of killing, we are not allowed to say that it has been finally vindicated; it has to face other challenges in other areas, in particular in situations of distributive justice.

Are there any good arguments in defence of moral nihilism? I think not.
