I’m discussing contraception with someone. Based on what I’ve learned from Mary Rosera Joyce, I’m pointing out that there is more than one purpose to sex, but the specific purpose is procreation.
(I realize that there are two main, inseparable purposes, which are bonding and procreation. But there are other moral ways to bond. But no other moral ways of procreation.)
I’m saying that because the specific purpose is procreation, contraception is wrong.
He responded by saying the specific purpose of a bed is sleeping but it can be used for other things too. Is it wrong to use a bed for sitting?
Likewise I said that there is a natural connection between sex and procreation. He said, well, there is a natural connection between gravity and falling to the ground. Is it wrong to stop something from falling to the ground?
How do I answer these arguments?
