I've been thinking about the last blog article for a while now ("Happiness is the Only Logical Pursuit"
http://www.mrmoneymustache.com/2016/06/08/happiness-is-the-only-logical-pursuit/), and I'm coming up with a lot of questions and problems with the MMM philosophy. He's great at early retirement math and being motivational to that end, but I think he really struggles with philosophy. Which is understandable, as his background is engineering, not philosophy.
At any rate, a couple of basic, glaring questions that aren't covered:
If we are just our brain chemistry ("meat machines"),
why is "natural" happiness preferable to "induced" happiness through drugs? He seems to be touching on the idea of "fulfillment" (natural happiness is more fulfilling than chemical happiness) but doesn't flesh that out - what is "fulfillment," and if it too is just a chemical in my brain, we're back to the original question - why not just take a pill? If happiness despite life situation is the "endgame" a pill to alter my brain chemistry into the feelings of happiness should be sufficient.
If I am just a meat machine (I think his exact words are "you are nothing more than a complex machine made of meat"), then is there free will? Machines can't go against their programming... in which case, there's a sticky discussion about criminals, laws, and whether I can even actually choose to retire early or not. After all, maybe my meat machine programming is telling me that I need to be a consumer sucka. What is the part of us that "chooses to change"? Computers can't go against what they've been programmed to do. Even complex ones. So when he says, "happiness automatically includes...being good" and doesn't flesh out what "being good" is, or why someone would "be good" if that's not in their meat machine programming, there's a philosophical problem.
I also think it's interesting that Pete tries to shoehorn his "meat machine" philosophy into Stoicism and Buddhism - while acknowledging
these philosophies get it right, he denies the greater spiritual underpinnings that these philosophies are based on.
He really seems to be struggling with a greater meaning to life. I'm interested to see where he ends up.
