The death penalty is a justified response to intiated evil, as is killing in war and self-defense situations. These are responses to evil.
An unborn child never initiates evil by coming into existence, neither in fringe cases of rape or threat to the mother’s life. The unborn child is always innocent because it never violates anyone’s rigjts. Abortion is always willful murder of the completely innocent.
I agree with you that self-defense, the death penalty, and war (when just) are responses to evil initiated by another.
I also agree with you that an unborn human life in the womb hasn’t committed any moral evil.
However, this doesn’t resolve the Jewish-Catholic problem, as I understand it. If from the Jewish perspective, the human life in the womb is not a
person in the same sense that the mother is, then an abortion would not be considered murder.
Think about it- even from a Christian point of a view, in order for an act of killing to be murder, the one being killed must be a human person.
We cannot murder a tree. Though a tree is perfectly alive. Nor can we murder an elephant, even if is on the list of endangered species. Nor can we murder an angel, because an angel is pure spirit.
What makes a human being, a
person?
Aristotle distinguished between:
- First potentiality (e.g. a man who is illiterate, but can learn to read)
- Second potentiality/ first actuality (e.g. a man who knows how to read, but is sleeping)
- Second actuality (e.g. a man who is actively reading)
You’ll see why this is relevant.
Aristotle’s defintion of
soul:
The soul is the first actuality of a natural body that has life potentially.
Aristotle distinguished between three different powers of the soul:
- The vegetative power: this is the power that plant life possesses, and all life in general; thus all plants, and all life forms are said to possess a “vegetative soul”, which simply refers to the actuality that gives the organism the powers of growth, development, movement, nourishment, and reproduction. What distinguishes a live frog from a dead frog, even if the organic matter in both are identical? One has a vegetative soul, and the other doesn’t. One is actualized, and the other isn’t.
- The sensitive power: this is the power that animal life forms possess; thus animal life is said to possess a “sensitive soul”, which simply refers to the actuality that gives the organism the powers of locomotion and sense perception.
- The rational power: this the power that human life forms possess; thus human life is said to possess a “rational soul”, which simply refers to the actuality that gives the organism the powers to think and reason.
For Aristotle, these degrees of soul are hierarchical, and the higher soul subsumes the lower soul(s). Plants have a vegetative soul; animals have a vegetative and sensitive soul; humans have a vegetative, sensitive, and rational soul.
Remember, “souls” are not separate entities for Aristotle. The soul is simply the
actualizing form of a body.
