A zygote isn't equivalent to a human life.
A fetus isn't equivalent to a human life.
I could go on and on and on. The point in which you draw the line is arbitrary.
I don't view a zygote as an independent organism with rights. That is the point. "potential life" is a meaningless statement.
Indulge me for a minute if you will. A little about me: I was robbed of my future when sent to a juvenile detention center for accidentally catching my school on fire. My education suffered, and my character severely questioned. I had plans of becoming a physical therapist. I was an honor student prior to this event, I was beaten relentlessly in the detention center, and my grades suffered greatly after. Needless to say I was hard pressed to be accepted to a reputable University after my basic education was completed. I ended up going to a technical college and became a HVAC technician. My girlfriend, whom I had met on the job, had my unborn child killed, despite my opposition. It devastated me. I literally broke. Soon after I broke down, I started self medicating, which ended up becoming a life long battle. My future was taken from me because I threw a cigarette in the garbage when my teacher walked in the bathroom. While robbing potential futures aren't criminal, taking human life is. At least it is for those considered to be persons. The entire issue boils down to the ideal that humans should have basic rights and when humans establish person hood. When are we considered to be unique individual human beings and valuable? At conception? Zygote stage? Fetal stages? At birth? Human rights are central to the discussion, as are human ethics, and the principles of human justice. With that said, I'd like to present a question. At what stage does the ideal of human rights have value?
0. As an ideal?
(seed)
1. After the ideal has been conceptualized?*
(fertilization/germination)
2. When the ideal has made some developmental progress?*
(roots)
3. After the ideal has made substantial developmental progress and has gained momentum?*
(stems and leaves)
4. When the ideal has nearly completed its developmental progress and is reaching completion?*
(flowers)
5. After the ideal has been given birth, becoming a very real part of our own human existence?*
(produces fruit)
An individuals human development begins immediately after the fertilization of the cell. As I stated prior,
"zygote" is a term used for a human person in early stages of development. The many different stages we all go through entail varied abilities and appearances. We grow, we develop, we gain different abilities, and our appearance changes throughout our entire life span. When we were born, we had far less abilities and our appearance was far different than now. When we became toddlers our abilities increased and our appearance further changed, and on to our teenage years, adulthood, middle age, to senior citizen and until we die. Our individual human life began the moment we were conceived. We remain in constant and ongoing processes of development throughout our entire life span. Our life began when a sperm fertilized a cell. Human person is the zygotes inherited quality.
With that said, and despite the absolute and unequaled power woman hold to terminate every potential and unborn human life that could possibly ever be given life in this nation, my understanding of what constitutes an individual human person is what changed my position to pro life. I didn't change my stance when my unborn child was denied birth and terminated, nor when I realized the reality that a power no human entity should hold has been granted to ~ 160,000,000 humans in this nation. I changed my position when I realized that the cluster of cells implanted to the uterus are individual persons beginning their journey of life. I'm not a religious man. Rest assured, I am not viewing this issue in terms of morality, but rather in terms of human ethics, principle and law, human rights, and human justice.
I used the ideal of human rights in this discussion for one reason. To encourage others to pinpoint inherent value. At what point does the ideal of human rights become valuable? Please answer. Being that human rights are central to this issue, at what point does human life become valuable? Science has established that humans begin their individual journey of life the moment of conception. If we fail to recognize these beginnings as human person-hood, we risk to err on the side of discrimination based on the sole reasoning of them not being able to think like us, feel like us, reason like us, breath, look, or act like us. What we're are essentially doing is discriminating against early individual human persons based on them not being like ourselves, or based on where we ourselves are on our own personal journey's.
