I believe human intelligence and emotion (the soul, if you will) is an emergent property of our physical brains. No brain, no soul. My Christian friend disagrees. He believes the soul is an "immaterial" property of humans, a property that apparently applies to brainless embryos as well as adults.
I want to better understand my friend's belief. Does this "sanctity of life" apply to gametes as well as embryos? What about the thousands of skin cells I shed every day, each of which has the same genetic complement as the fertilized egg I developed from? What about the third of embryos whom his God aborts? What about other sapient lifeforms, like dolphins and chimpanzees? Why doesn't treating a disease postnatally interfere with God's plan?
I made the following questionnaire to try to probe at my friend's belief. I chose a multiple choice format to make it harder for him to weasel out of questions with answers like, "I don't know, but we should err on the side of life." I'm looking for feedback and ways to improve the questionnaire. Plus, I'm curious as to how the patrons of SDN will answer
The following questions are designed to measure your beliefs regarding the sanctity of human life. Please choose the one letter that best represents your opinion for each question. If you wish, you may write a 1-2 sentence explanation for each of your answers. There are no "correct" answers.
For Question 1, you may choose zero, one, or more letters.
1. Mammals, such as humans, develop from a single cell called a zygote. A zygote has the same genetic complement as every cell in the organism it could eventually develop into. Zygotes, in turn, arise from the union of two gametes -- a sperm and an egg. A gamete has one half the genetic complement of a zygote. Which of the following statements regarding the intrinsic moral agency of single cells do you agree with? Indicate all that apply.
A. A human zygote has more of a right to exist than a feline zygote.
B. A human zygote has more of a right to exist than a human sperm.
C. A human sperm has more of a right to exist than a feline zygote.
D. A human sperm has more of a right to exist than a human keratinocyte.
E. A human keratinocyte has more of a right to exist then a feline zygote.
2. IVF (in-vitro fertilization) works by culturing several blastocysts, five day old embryos made of 70-100 cells each, of which the healthiest are then placed in the prospective mother's uterus to implant and develop normally. The unused blastocysts are frozen in case the mother wants to use them later. These frozen blastocysts will eventually be destroyed if nobody wants to use them. You are a lab assistant at an IVF clinic, which is presently on fire. In the room with you is a single blastocyst scheduled for destruction and your boss's cat. You can only save one of these from the fire. Which would you save?
A. The Blastocyst
B. The Cat
3. You are a lab assistant in the same doomed IVF clinic as in Question 2. This time you must choose between your boss's six year old daughter and a tank of frozen blastocysts. You would save the girl instead of the tank so long as the tank contains fewer than:
A. 1 blastocyst
B. 10 blastocysts
C. 100 blastocysts
D. 1000 blastocysts
E. It doesn't matter how many blastocysts there are, you would always choose to save the girl.
4. You are a doctor at an IVF clinic with an excellent fire suppression system. As per standard procedure, you create two blastocysts for a prospective couple, but you can only implant one of them (the other will most likely be destroyed). Genetic testing reveals that one of the blastocysts will (with better than 99% certainty) develop Tay-Sach's disease, a debilitating illness that leads to death no later than the age of five. There is no known treatment for Tay-Sach's disease. Which blastocyst would you choose to implant?
A. The blastocyst with Tay-Sach's disease.
B. The healthy blastocyst.
C. Neither blastocyst.
D. You would choose one of the blastocysts at random.
5. You are a doctor at the same IVF clinic as in Question 4. This time you create only one blastocyst, and genetic testing reveals that it will develop Tay-Sach's disease. From this information, you can infer that every blastocyst you create for the couple in question will have a 25% chance of having Tay-Sach's disease (and thus a 75% chance of being healthy). Regardless of how many blastocysts you create, you may only implant one of them. You would:
A. Implant the first blastocyst.
B. Create a second blastocyst and implant it without testing it for Tay-Sach's disease.
C. Create a second blastocyst and, if it also tests positive for Tay-Sach's disease, implant one of the blastocysts at random.
D. Create a second blastocyst and, if it also tests positive for Tay-Sach's disease, send the couple away without implanting either blastocyst.
E. Keep creating blastocysts until you obtain one without Tay-Sach's disease, then implant the healthy blastocyst.
Questions 6 and 7 refer to technological advancements that have not yet occurred but that are well within the realm of possibility.
6. You are a doctor at an IVF clinic 30 years in the future. You create a single blastocyst for a couple, and genetic testing reveals that it will develop Tay-Sach's disease. You know that each parent carries two copies of the gene associated with Tay-Sach's disease -- each parent has one healthy copy and one diseased copy. The blastocyst has two diseased copies. Using your futuristic technology, you can replace the blastocyst's two diseased Tay-Sach's genes with two healthy genes -- one from each parent -- while leaving the rest of the blastocyst's genome undisturbed. This would prevent the blastocyst from developing Tay-Sach's disease. Assuming all treatment modalities have the same cost, you would:
A. Use the futuristic technology to cure the blastocyst of Tay-Sach's disease.
B. Choose the same course of action as in Question 5.
C. Let the prospective parents choose between A and B.
7. You are a doctor at an IVF clinic 30 years in the future. You create a single blastocyst for a couple, and genetic testing reveals that it will develop Tay-Sach's disease. You do not possess the technology to repair the defective gene as in Question 6, however you do possess the technology to insert a synthetic, heritable gene into the blastocyst. The synthetic gene will negate the diseased gene, allowing the blastocyst to develop into a normal child without Tay-Sach's disease. Aside from the presence of the synthetic gene, the genome of the blastocyst will be undisturbed by this procedure. Assuming all treatment modalities have the same cost, you would:
A. Use the futuristic technology to cure the blastocyst of Tay-Sach's disease.
B. Choose the same course of action as in Question 5.
C. Let the prospective parents choose between A and B.
For Question 8, assign each letter a rank.
8. You are a doctor treating a child with Type I diabetes. Your patient cannot produce a hormone called insulin, so you must regularly inject him with exogenous insulin or he will die. The following treatment modalities are available; they have been ranked in order of expense with (A) being the most expensive and (C) and (D) being tied for second least expensive. Assuming all insulin-based treatment modalities are equally effective, rank these treatment modalities in order from most ideal to least ideal.
A. Human insulin isolated from the donated blood of living humans
B. Porcine insulin isolated from the pancreata of dead pigs
C. Human insulin produced synthetically in a laboratory
D. A synthetic insulin not found in nature that requires fewer injections
E. Saline solution (a placebo)
9. A research scientist is developing a treatment for epilepsy. Epilepsy is a neurological disease with symptoms that can range from mild to to so severe that half of the brain must be surgically removed. She plans to transform a keratinocyte (skin cell) obtained from an epileptic patient into a neuron (brain cell). The neuron will then be cultured (grown) on a computer chip. She plans to use the computer chip to stimulate the neuron electrically and record it's response, all while subjecting it to various anti-epileptic drugs. At the conclusion of the experiment, the neuron will be destroyed. You are a member of the IRB (institutional review board, an ethics committee that oversees medical experiments) that will either allow or prohibit the researcher from carrying out her experiment. You would vote to:
A. Allow the experiment.
B. Allow the experiment, but only if the cultured neuron is given an anesthetic.
C. Allow the experiment, but only if the cultured neuron is allowed to continue living on the computer chip once the experiment is over.
D. B and C
E. Allow the experiment, but only if rat neurons are used instead of human neurons.
F. Prohibit the experiment.
10. Which of the following best describes your spiritual beliefs?
A. You are a Christian, and you believe the bible is literally true.
B. You are a Christian, but you believe some parts of the bible are metaphors.
C. You are a theist who belongs to an organized religion besides Christianity.
D. You are a theist, but you don't really subscribe to any particular religion.
E. You are an atheist, but you feel as if there's something spiritual out there.
F. You are an atheist and a secular-humanist/freethinker.
