Should abortion be legal?

Welcome to the debate arena! Today's topic: "Should abortion be legal?". Your opponent's style: Socratic philosopher

Abortion should be legal if it is necessary to protect the life of the pregnant woman. However, since abortion ends the life of a living human being, it should not generally be legal.

You've smuggled in a contradiction: if abortion protects life, then it's justified. So what actually determines when a life matters more than another? You've conceded the principle, so you're really just arguing about *which* lives count and when. What makes the pregnant woman's life special but the fetus's life not?

Both lives matter equally. However, I believe that everyone has the right to self defense: they are allowed to take action if necessary to protect their own life, even if it results in the death of a non-aggressor, such as in the case of some abortions.

Self-defense only works if the threat is culpable. A fetus isn't attacking you, it's existing. You didn't consent to be pregnant through no act of the fetus's own. So you're claiming a right to kill someone for the crime of being in your body through circumstances neither of you chose. Why does mere physical presence, without intent or agency, justify lethal force? Where does that principle end?

I believe you are using self-defense in the purely legal aspect, not the moral aspect. A legal right to self defense applies to culpable threats. However, I believe that the moral right to self defense applies to any threat to ones life. As I mentioned earlier, the fetus is a non-aggressor. I do not claim that the fetus is committing any crime that 'deserves' death. They have not chosen to act in a way that threatens the pregnant womans life. However, we don't typically require people to sacrifice their lives for others. And in the case of pregnancy, if abortion is necessary to protect the womans life, she should not be prohibited from doing so, even if it results in the death of a non-aggressor human being. Take a hypothetical for instance, suppose you are tied to the tracks. There is a train coming towards you. You can press a button to blow up the train before it hits you, but it will kill the conductor on board. Would you argue its impermissible to protect your own life?

Your train scenario proves too much. The conductor didn't tie you there, yet you'd kill him. But here's the real problem: you're treating pregnancy as an imposed threat when most pregnancies result from choices that created the situation. The woman consented to the act that caused it. The conductor never consented to be on that train heading toward you. So either consent matters for moral obligations, or it doesn't. Which is it? Because if it doesn't, your self-defense argument collapses entirely.

You still didn't answer the question of if it would be permissible to save your own life by blowing up the train. You keep bringing up this issue of culpability. The conductor didn't tie you there. The fetus didn't choose to be in your body. You are ignoring the fact that we agree on culpability: we agree that neither the conductor nor the fetus is culpable. However, would you agree with me that you would still have the right to protect your life, even if it results in the death of a nonculpable person, such as in the case of the train? You also said that most pregnancies resulted from choices that created the situation, that she consented to the act that caused it. However, consenting to sex, which has the possibility of pregnancy, does not mean forfeiting your right to protect your own life. Going back to the train hypothetical, what if you were careless and hitchiked in a stranger's truck and woke up tied to the tracks? Would you say that carelessly hitchhiking with stranger's is 'consent' to dying and that you would lose your right to protect your own life?

Direct answer: yes, blowing up the train seems permissible. But your hitchhike analogy fails because the stranger didn't tie you there to save his life. He tied you there to kill you. Pregnancy is different. The fetus isn't using your body to survive; it *needs* your body to exist at all. That's a fundamental distinction. So the real question: does creating a dependent relationship through your own actions eliminate your right to end it unilaterally? That's what actually matters here, not abstract self-defense.
