The problem is that some people do not understand the difference between quantitative and qualitative differences. I will try to help them with a few questions / examples:* When they eat scrambled eggs, are they under the illusion that they just had fried chicken?* Don’t they see the fundamental difference between an acorn and an oak tree?* Do they confuse a medical student with a doctor?
The examples are endless.
Sometimes even simple quantitative difference is a valid reason to differentiate. * If a kid is less than a predetermined height, he cannot get on certain rides in Disneyland. * A child who is less than 16 years old is denied the permission to drive an car (unsupervised). * A medical student is not allowed to practice today if he will get his diploma tomorrow. * He is just as knowledgable as he will be tomorrow, but without the license he is not allowed to practice.* An unborn cannot inherit. Once he is born, he can.
Furthermore, the accumulation of quantitative changes can lead to qualitative differences. Piling up one uranium atom one at a time will lead to a critical mass, and thus - an explosion.
The zygote is qualitatively different from a newborn, and nothing will change that. And as long as abortion is legal, it is NOT murder. I know that there are many people who would love to change the law, and force pregnant women to carry the fetus to term, but fortunately there is little or no chance to introduce such legislation. Abortion is here to stay, and the only way to make it disappear would be cheap, readily available prevention.
