本文探讨了作为“博尔兹曼大脑”这一假说下的存在，我们应如何应对。博尔兹曼大脑是一种假说中的意识存在，可能在极短时间内瞬间生成又瞬间消散。文章认为，在这种极端短暂的存在中，最理智的选择是放下对未来的担忧，专注于当下，享受每一个瞬间。即使影响微乎其微，也能从“活在当下”的体验中获得积极的价值，甚至可能对同一参照系中的其他博尔兹曼大脑产生积极的“证据”影响。文章鼓励读者，无论是否真是博尔兹曼大脑，当意识到这种可能性时，都应以一种放松、开放、享受的态度来面对，因为这可能带来意想不到的积极结果。

🌟 **拥抱当下，享受短暂存在：** 如果你是博尔兹曼大脑，你的存在极其短暂，很可能瞬间消散。因此，最明智的做法是放下对未来的顾虑，以一种禅意的、放松的、开放的态度去享受当下，即使只有片刻的幸福，也应珍惜。

🚀 **微小影响，无限可能：** 尽管你的行为可能无法产生长远的影响，但从证据的角度来看，你当下所做的选择，可能决定了同一参照系中无数其他博尔兹曼大脑的体验。因此，即使是短暂的积极体验，也可能具有“证据”上的重要性。

💡 **理性抉择，及时行乐：** 面对“博尔兹曼大脑”的假说，不必过度纠结其物理或道德的真实性。如果享受当下的体验比其他任何选择更有可能带来正向价值，那么就应该选择享受，这是一种基于概率的理性决策。

🧘 **放下执念，轻松面对：** 当你开始思考自己可能是博尔兹曼大脑时，这本身就是一种认知。这时，最佳的回应是“放下”，保持放松，享受当下，因为这种心态甚至可能创造无限的积极价值。

If^[1] you’re a Boltzmann brain, you should probably just enjoy the moment.

This is probably true not just from an obvious standpoint, but from a moral standpoint as well.

If you are a Boltzmann brain, then you will probably more or less instantaneously disintegrate. 

But there is an absurdly small chance that your Boltzmann environment might be such that you are able to influence the next moment of your experience. The absurdity of your continued influence climbs exponentially each proceeding moment, so you should probably just stick to influencing the very next influenceable moment.

Since you have virtually no time, you can’t really do much besides take a Zen delight in your absurd predicament, maybe just instantaneously turn on a relaxed, open, mindful, enjoying attitude, a short blissful moment of Satori before you die. (Feel free to continue doing so as long as you exist.)

Causally, your influence will probably be pretty small. But evidentially, you could be deciding what an infinite number of other Boltzmann brains in your same reference class are doing.

While you might think that, since you’re a Boltzmann brain, the argument and physics knowledge this is based on are actually illusory, just a random thought pattern, out of all possible ridiculous random thought patterns your Boltzmann brain could have quantum collapsed on, and so there’s not really any strong reason to assume the physics or argument is correct. To get the right answer, you would really need to figure out what the most likely physics and moral logic of a universe allowing for observers in your reference class is, from first principles, and then quickly act on that.

But we ain’t got time for none of that! We’re Boltzmann brains, remember!! As long as you find yourself thinking about this argument and find it more likely to be true than some argument with an opposite conclusion, the expected value of enjoying the next moment is positive, so go ahead and enjoy!

Therefore, anytime you find yourself thinking about how you might be a Boltzmann brain, no need to stress, the best thing to do is just let go, relax, and enjoy the moment, you might even be creating infinite positive value 🙂

Note: also applies to the eternal inflation level of the multiverse due to the “Youngness Paradox.”

   Of course, you might not be at Boltzmann brain; this post only focuses on what we ought to do if we are one.
