Two words that get mixed up
The text starts by clearing up two meanings of the word death:
- biological death: when the body stops working for good;
- annihilation: when the person stops existing forever and will never have experiences again.
Some people believe there's life after death. Others believe death is the end. The text asks: does this uncertainty change anything in our decisions?
If the current life is good
Imagine someone whose life is (and would keep being) better than not existing. They can keep living or die now. And they don't know what comes after. The author looks at the possibilities:
- if death is the end, it's better to keep living;
- if afterward there's a worse life, but still better than not existing, it's better to keep living;
- if afterward there's a life worse than not existing, it's better to keep living;
- only if afterward there's a life better than the current one would it be better to die.
In most scenarios, when life is good, living is the best choice.
If the current life is very bad
Now imagine a life that is (and would keep being) worse than not existing, full of suffering. In that case, in most scenarios, ending that life would be better for the one living it.
Complications
The text points out that there are still many open questions: how long would a life after death last? Would the moment of death change anything about it? These questions make the calculations harder.
The conclusion
It might seem that uncertainty about what comes after death would mess up all the reasoning in this volume. The author concludes that, in general, it doesn't: when a life is good, protecting it is still the most reasonable thing to do.
In short
- "Death" can mean the end of the body or the end of the person.
- When life is good, living is usually the best choice in almost every scenario.
- Uncertainty about the afterlife doesn't change the conclusions of this volume much.
