Maybe I didn't use email for 20 years because I'm not even 20? Well I did research on the Nigerian scam, and it seems they just lie about the potential to make money.
1) Embryos on the other hand have the potential to become a human and nothing else (besides dead).
2) The earlobe has no chance of achieving sentience ever until that special circumstance happens (which is the chemical treatment Sweeney mentioned).
3) For the cake analogy, there is two cases (revised by me to be more relevant to abortion)... The original analogy didn't really apply to abortion, so
4) And the electron is in a probability cloud based on its energy level around the atom 90% of the time.
I wasn't saying that you should have used email for the entirety of your lifespan (or 20 years), I was saying that if you had used email at all during that time, you would in all likelihood have gotten an email from a Nigerian prince.
The case is relevant because the email creates the perception of value. Most commodities trade on a perception value market. No one really believes that price reflects value 100% of the time, right? Otherwise there would be no crazy swings up and down on the stock market. Value is subjective, illusory, and never fully captured in figures.
An embryo is likewise a perception of value, the illusion of a future human. Until it is real and true, it is a lie and false.
1) Embryos are nothing but cells. As Sweeney has brought up, cells can be re-purposed. Stem cells were only the beginning. You're trying to dismiss the potato argument out of hand. But the possibility of other outcomes is there, whether you're willing to admit it or not.
2) That "until" kills your argument. The "
ever" is made irrelevant by even one counter example, which Sweeney has given. Illicit affirmative or negative.
Logic hurts.
3) If you change my argument, it ceases to be my argument. You understand I'm not responding to that butchery of my poor cake mix example, right? Please don't try to give me an argument that I didn't come up with.
Cake mixes are potential cakes. Embryos are potential humans. The fact that added effort is still necessary in both cases is, I think, rather self evident. The point being that until you expend that potential energy, you don't have a cake or a human.
4) Congratulations on googling my query, but that's not exactly what I asked.
