An abortion is the medical process of ending a pregnancy so it does not result in the birth of a baby. Abortion has always been a major issue of discussion in our society and there are always different opinions on abortion. I am against this practice and I think abortion should be illegal.
To start with, it is false to claim that no one knows when life begins and dishonest to argue that abortion does not kill a human being. Every new life begins at conception. This is a known fact of biology. It is true for animals and true for humans. No matter what the circumstances of conception, no matter how far along in the pregnancy, abortion always ends the life of an individual human being.
Prominent defenders of abortion rights publicly admit that abortion kills human beings. They are not saying that abortion is morally defensible because it doesn't kill a distinct human entity. They are admitting that abortion does kill a distinct human entity, but argue it is morally defensible anyway.
Personhood is properly defined by membership in the human species, not by stage of development within that species. A living being's designation to a species is determined not by the stage of development but by the sum of its biological characteristics— actual and potential—which are genetically determined. If we say that the fetus is not human, e.g. a member of Homo sapiens, we must say it is a member of another species. But this cannot be.
Dictionaries define person as a “human being,” “human individual,” or “member of the human race.” What makes a dog a dog is that he came from dogs. His father was a dog and his mother was a dog, and therefore he is a dog. What makes a human a human is that he came from humans. His father was a human person and his mother was a human person, so he can be nothing other than a human person.
