To start with an analogy: you're on a boat in the middle of the ocean, and you learn it is slowly sinking. Assuming you want to live, you might search for a life jacket, a flotation device, or any other sort of thing that could save your life. However, someone protests: "Why bother looking for a life jacket? I don't think there's any stored on this boat. In fact, I'm fairly sure we're going to die. The chance of survival seems fairly low given our situation. Here is my reasoning [xyz]." On this basis, would you say "You know, you're right, we're probably going to die" and sit down waiting for death? Or would you continue searching for a way to survive, despite the apparent futility?
I thought I would formalize this a bit:
Let “utility” refer to the usefulness of a given outcome toward a goal (in this case, your future well-being). Outcomes that increase one’s future well-being are given positive utility, and outcomes that decrease one’s future well-being are given negative utility.
𝐏𝟭 A belief that accepts death as the permanent terminus to life results in infinite negative utility for the one who adheres to such belief.
𝐏𝟮 A belief that entails infinite positive utility is infinitely preferable to a belief that entails infinite negative utility.
𝐏𝟯 Naturalism is a belief that entails infinite negative utility for the adherent.
𝐏𝟰 Theism is an example of a belief that can potentially entail infinite positive utility for the adherent.
𝐏𝟱 Therefore, the Naturalist should seek to falsify and abandon Naturalism in favor of beliefs like Theism.
Considerations
- This argument might be thought to resemble Pascal’s Wager. Unlike Pascal’s Wager, however, it is not being argued that one should look to adopt Theism due to its infinite positive utility; instead, the argument is that one should look to reject Naturalism based on its infinite negative utility.
- Why would 𝐏𝟭 be true? On Naturalism, I take it that our life has no objective (i.e. mind-independent) purpose or meaning outside of self-created, self-imposed, and illusory ones. Our existence would be a brute fact, and we simply live, die, and then stop existing for all eternity.
- Our finite existence is overshadowed by the reality that death will swallow everything we know, do, and love. Given that we can no longer exist on Naturalism after we die, this means we forfeit all positive utility both realized and unrealized in the end— death is an infinite loss. As such, any potential positive utility added onto a person’s temporary life results in the same outcome, much like adding a finite number to negative infinity still results in negative infinity.
- The Naturalist might say, "This argument only works if we assume utility ought to be measured out infinitely far into the future. If we accept the end of our life as the endpoint for utility, then our finite life can result in finite positive utility." If we let utility mean future well-being, then why arbitrarily stop measuring the impact of the future at the end of one’s life? That’s like burying your head in the sand in the face of a massive tsunami and saying, “everything’s just fine if I don’t look!” In addition, it’s not how people tend to look at other endeavors that affect peoples’ lives after they die. For example, people typically want to make positive political changes in the world before they die, leave the world a better place for their children, invent something that will make a mark on history, etc. After all, the universe continues on into the future even if the Naturalist doesn’t. Any positive utility gained now must be measured against the looming reality of infinite meaninglessness and nothingness that the future promises; the Naturalist should therefore consider how this impacts his decisions now.
EDIT: Thanks everyone for the input. The conversation was lively and I now feel more confident in this argument than I did before.

Yeah, this is still just Pascal's Wager.
Also, P1 is not true because knowing your have a finite lifespan is often stated as liberating among atheist circles, and results in greater empathy and a stronger desire to make a positive mark on the world, or at the very least leave it a better place than we found it for future generations..
