It seems many people think creating a life has zero value. Some believe this because they think the average life contains about the same amount of suffering and satisfaction. Others have more conceptual objections, for instance to the notion that a person who does not exist now, and who will otherwise not exist, can be benefited. So they believe that there is no benefit to creating life, even if it’s likely to be a happy life. The argument I will pose is aimed at the latter group.

As far as I know, most people believe that conditional on someone existing in the future, it is possible to help them or harm them. For instance, suppose I were designing a toy for one year olds, and I knew it would take more than two years to go to market. Most people would not think the unborn state of its users-to-be should give me more moral freedom to cover it with poisonous paint or be negligent about its explosiveness.

If we accept this, then conditional on my choosing to have a child, I can benefit the child. For instance if I choose to have a child, I might then consider staying at home to play with the child. Assume the child will enjoy this. If the original world had zero value to the child, relative to the world where I don’t have the child (because we are assuming that being born is worth nothing), then this new world where the child is born and played with must have positive value to the child relative to the world where it is not born.

On the other hand suppose I had initially assumed that I would stay at home to play with any child I had, before I considered whether to have a child. Then according to the assumption that any birth is worth nothing, the world where I have the child and play with it is worth nothing more than the one where I don’t have it. This is inconsistent with the previous evaluation unless you accept that the value of an outcome may  depend on your steps in imagining it.

Any birth could be conceptually divided into a number of acts in this way: creating a person in some default circumstance, and improving or worsening the circumstances in any number of ways. If there is no reason to treat a particular set of circumstances as a default, any amount of value can be attributed to any birth situation by starting with a different default labelled ‘birth’ and setting it to zero value. If creating life under any circumstances is worth nothing, a specific birth can be given any arbitrary value. This seems  harder to believe, and further from usual intuitions, than believing that creating life usually has a non-zero value.

You might think that I’m unfair to interpret ‘creating life is worth nothing’ as ‘birth and anything that might come along with it is worth nothing’, but this is exactly what is usually claimed. That creating a life is worth nothing, even if you expect it to be happy, however happy. I am most willing to agree that some standard of birth is worth nothing, and all those births in happier circumstances are worth more, and those in worse circumstances worth negative values. This is my usual position, and the one that the people I am debating here object to.

If you believe creating a life is in general worth nothing, do you also believe that a specific birth can be worth any arbitrary amount?
