Is Moral Nihilism a Morality?

[Alan V]

Here's a q, that doesn't get a lot of play, if relativism and/or nihilism leaves a person looking elsewhere for moral propositions, what "elsewhere" is there to look toward?

Well, let's say someone just became and atheist and wanted to investigate alternative ethical systems to get away from theistic morality.  Per Wikipedia, he has a range of choices including nihilism:

Ethical theories that can be naturalistic

• Altruism
  
• Consequentialism
  
• Consequentialist libertarianism
  
• Cornell realism
  
• Ethical egoism
  
• Evolutionary ethics
  
• Hedonism
  
• Humanistic ethics
  
• Moral skepticism
  
• Natural-rights libertarianism
  
• Objectivism
  
• Utilitarianism
  
• Virtue ethics
