The end of Philosophy

Dear children, your silly worldview of objective rights and wrongs is outdated and wrong. Morality is purely subjective, a matter of taste. I provide no evidence or reasoning for my opinions but I do expect you to be challenged and wowed by their far-reaching consequences.

If morality is purely subjective, then issues such as as gay marriage become purely a matter of taste. One person has taste for self-determination and thinks that gays should marry and another thinks gay sex is gross and that it should be banned. They are both right and totally justified doing whatever they feel is aesthetically pleasing (ie murder) to accomplish their ends.

This is a problem to say the least.

Effectively this means that there is no such thing as right and wrong and what we are left with is shallow consensus (as opposed to a reasoned consensus) at best, and application of force at worst. Slavery becomes right, because I'm a sociopath with a gun.

Let's just say that I subjectively think that it is morally obligatory for people to accept an objective moral norm.

If you think that there is some objective morality that is inherent to the universe, the burden of proof is very much on you to show that, not on me to disprove it. (But if you need a disproof, here's as close as I can get: I am 100% certain that you cannot give a definition of "morality" that both meshes with what's expected of the term and that implies the existence of some fundamental objective framework for determining what's right and what's wrong. Just think about it for a while.

Or, alternatively [and not equivalently, but evocatively]: we're all just particles. You can give any brilliant argument you like about the morality of an action, and my particles are just gonna keep on doing whatever the fuck they want.)

As you discuss, lack of objective morality is horrible. It still makes me feel weird when I think about it, and I decided that "ethics" was bullshit when I was thirteen. My brain is hard-wired to believe that certain actions are "right" and certain actions are "wrong" in a sense that encompasses more than just my brain's response to those actions, so thinking about (what I see as) the truth about morality causes a dissonance between my conscious and my subconscious.

In the same way, my brain believes very deeply that everything has a cause, so it believes that there's a meaningful answer to the question, "Why does the universe exist?"

But that question doesn't have an answer. And objective morality doesn't exist. Sorry.

Can you state more clearly where you think the problem is? Or is it simply that you don't find this arrangement preferable?

I wish this style of proof would penetrate through to postmodern philosophers. If everything that one person chooses to believe is true for them, and that person chooses to believe that there is an objective truth that precludes this statement, then you have a problem. This is not wordplay or an irrelevant point, any more than Godel's proof was. Either there are false statements about morality, or your claim that everything is subjectively true is also false. It's not a trivial point.

And I find that in practice, what gives is that postmodernists do in fact believe in absolute morality and it's all just a game to fool themselves and you into thinking otherwise. I see no reason to play that game any more, especially as I think most people would be repulsed if they took the time to work through what postmodern morality really is, instead of what it claims to be.

(This doesn't mean that we automatically know what the objective morality is, or whether there is one or many. It simply means that true subjective morality is fatally and irretrievably flawed. I say "true" because the moment you introduce an absolute, it is no longer subjective. Any absolute will do. Moralities can be quite complicated and nuanced, like utilitarianism, even as a utilitarianist must inevitably take their utility measurement as an absolute axiom. There isn't much "absolute" there, but it is non-zero.)

That said, reading the original article, I'm not sure that David Brooks would necessarily disagree with what I just wrote. I'm not sure he's advocating total relativism so much as observing that whatever concretes may exists seem to bear no particular relationship to the concretes that are claimed by anybody, religious (or aggressively non-religious), philosophical, or otherwise. I think there's a difference between merely observing and making claims about what should be true, and this op-ed strikes me more as an observation. So I guess I'm responding more to your comment than the article.
