Reddit mentions of Moral Realism: A Defence

At least for Anarchists or other left-libertarians it should also be important to actually read up on some basic or even fundamental ethical texts given most political views and arguments are fundamentally rooted in morality (unless you're a orthodox Marxist or Monarchist). I'm sadly not familiar enough with applied ethics to link collections of arguments for specific ethical problems, but it's very important to know what broad system you're using to evaluate what's right or wrong to not contradict yourself.

At least a few very old texts will also be available for free somewhere on the internet like The Anarchist Library.

Some good intro books:

• The Fundamentals of Ethics by Russ Shafer-Landau
  
• The Elements of Moral Philosophy by James and Stuart Rachels
  
• Ethics: A Very Short Introduction by Simon Blackburn
  
  Some foundational texts and contemporary authors of every main view within normative ethics:
  
  
• Nicomachean Ethics by Aristotles for Classic Virtue-Ethics. Martha Nussbaum would be a contemporary left-wing Virtue-Ethicist who has used Marx account of alienation to argue for Global Justice.
  
• Grounding for the Metaphysics of Morals by Immanuel (or Emmanuel) Kant for Classic Deontology. Kantianism is a popular system to argue for anti-statism I believe even though Kant himself was a classical liberal. Christine Korsgaard would be an example of a contemporary Kantian.
  
• The Methods of Ethics by Henry Sidgwick for Classic Utilitarianism. People usually recommend Utilitarianism by John Stuart Mill, but most contemporary Ethicists believe his arguments for Utilitarianism suck. 2 other important writers have been R. M. Hare and G. E. Moore with very unique deviations from classic Utilitarianism. A contemporary writer would be Peter Singer. Utilitarianism is sometimes seemingly leading people away from Socialism, but this isn't necessarily the case.
  
• Between Facts and Norms and other works by the contemporary Critical Theorist Jürgen Habermas may be particularly interesting to Neo-Marxists.
  
• A Theory of Justice by John Rawls. I know Rawls is a famous liberal, but his work can still be interpreted to support further left Ideologies. In his later works like Justice as Fairness: A Restatement you can see him tending closer to Democratic Socialism.
  
• Thus Spoke Zarathustra by Friedrich Nietzsche for... Nietzsche's very odd type of Egoism. His ethical work was especially influential to Anarchists such as Max Stirner, Emma Goldman or Murray Bookchin and also Accelerationists like Jean Baudrillard.
  
• In case you think moralism and ethics is just bourgeois propaganda maybe read something on subjectivism like Ethics: Inventing Right and Wrong by J. L. Mackie
  
• Or if you want to hear a strong defense of objective morality read Moral Realism: A Defense by Russ Shafer-Landau orc

>And I have a perfect grasp on epistemological underpinnings of my ethics.

Then give me the criterion for what "evidence" you would accept.

>The reason I say "I don't know" is because I don't know what you think is the basis for objective morality.

Well, there are arguments for moral realism on its own basis without reference to God or anything else. For a great start I would point you this (which is on my shelf): https://www.amazon.com/Moral-Realism-Defence-Russ-Shafer-Landau-ebook/dp/B002BWPIJS?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-d-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B002BWPIJS

Moral truths are categorically the same as epistemological truths. If you want to dismiss moral realism then you also have to dismiss the idea that there can be such things as informal logical fallacies.

>I can't say what it would take to agree with you because I don't know what the underlining claim is.

The claim is that moral realism is true. Your evidentiary standard now?

>My view on actions is based expressly in how they manifest in the natural world. As such my opinions are not arbitrary but based on physical evidence and realities.

The importance you assign to "physical evidence and realities" is still subjective and arbitrary- meaning that your standard is ultimately arbitrary.
