On what basis do you claim that a zygote, a comatose person, or a person with such severe dementia that she cannot recognize her own children has “the capacity and eventuality” to “understand and act upon representations of morality”?
Yes, I shall explain this further. Generally "understanding" representations of morality means to have an awareness of concepts of right/wrong . I would argue that even a individual with severe dementia would have such an awareness.This is because memory, or even intellect is not linked with such an awareness. More simply put, the ability to be empathetic (which is generally where this awareness seems to arise from) is something which makes us human. However my definition is not exhaustive. There many other definitions argued by philosophers (for example some argue that a 'person' is a social being who develops relationships with others, can form belief systems, can feel a variety of complex emotions). What I am interested here is the eventuality.
Those patients who are comatose may or may not have the capacity/eventuality for such an awareness depending their state. A common example which I give to illustrate this position is as follows. Consider three individuals who are in a Coma. Patient A will never come out of Coma (they are in essence braindead with no chance of recovery). Patient B may or may not come out of Coma (they have a possibility to do so). Patient C will come out of Coma after a certain period of time (lets say 3 months). Now, in this state of Coma, the patient are not conscious or have a semblance of consciousness (they are not sentient, no awareness of morality etc). I also assume that there is no dispute that once (and if) the patients come out of Coma, they have an indisputable right to life. Now what about right to life of these 'already in coma' patients? I would argue as follows:
Patient A
does not have a right to life. She will never recover and hence does not have a eventuality to be a "person" (i.e by awareness of morality/ sentience etc). Therefore there is nothing wrong in ending her life. Patient C, I believe does have a right to life. She has the eventuality to be a person (if left alone in that state she will recover from the coma and be a 'person' as we understand it). Patient B however is a bit more interesting. I would (and many would argue) that the potential to recover is enough to warrant a right of life. There are others who disagree though (and say potential is not enough).
However the point I am making, is that the scenario of the fetus is analogous to that of person C. Both the fetus, and person C, if left in that state (of support, either by the mother or the hospital) will become something that has the right to life (an infant, or a post coma individual) and if it is wrong for for the hospital to withdraw life support from person C knowing full well that they would recover, then it is also equally wrong for a women to abort the child knowing full well that she (the fetus) would 'gain right of life' after a certain period of time.
By the way, doesn't any unfertilized egg residing in a woman's body and any sperm residing in a man's body have the same capacity for moral behavior as a zygote has? I would say that the line that you have drawn to define “person” is arbitrary (in more ways than one). A minute-old fertilized egg, an unfertilized egg and a sperm cell all engage in the same moral behavior at present..
Capacity must be differentiated from potential, because this is a common misunderstanding that occurs. Potential for X means there is a chance that X will occur but it requires external interference (i.e the action of another moral agent, or some chance event perhaps). Capacity and eventuality is understood as twofold. Firstly, capacity for X means an individual at any given moment can choose to do X (without needing interference from another moral agent) while eventuality means at some point in time onwards, the individual will most likely than not develop a capacity for X. An infant will more likely than not develop into an adult (if her current state is left unhindered). That is why an infant has the
eventuality to become an adult. A lottery ticket has the
potential to become money (in that the potential is dependent on either the action of another moral agent: someone drawing out lotto numbers, or a chance event: lotto numbers matching the ticket's). These concept must be confused, and is what I used to distinguish between zygotes and gametes, and is something that your scenario fails to incorporate. In a schooling system, a person who is in a lower grade, will
more likely than not move up to the higher grade (that is the general trend, barring something extraordinary happening). That is why the distinction is arbitrary because all students have the eventuality to sit the SATs (provided they are enrolled in that school). In the case of the gamete and zygote, the gamete it not
more likely than not to become a infant because it is dependent heavily on the actions of another rational agent (i.e that parents to have intercourse). See below for my discussion on this.
A minute-old fertilized egg, an unfertilized egg and a sperm cell all engage in the same moral behavior at present.
Without going too much into discussion of causality, (moral) actions are those are initiated by a moral agent. A gamete can never become a human being without a
direct moral action of another rational agent (i.e sexual intercourse by parents). A zygote however is a result of that moral action, and requires no conscious action (from any moral agent) to develop into a person. They may require support, but the development from a zygote to an infant is not dependent exclusively on the actions of moral agents, while the development from a gamete to a person does. There is a change of state, morally I believe, from a gamete to a zygote. Simply put, if a gamete is left alone (in its original state) then it will never become a person. If a zygote is left alone (i.e no action is performed directed towards her, but the mother goes on with her life), then that zygote will develop into an infant at the least (the development from infant to person is a little bit more complex, but I assume people are generally OK with giving infants rights).
Also by the way, all definitions of “person” in the law are flagrantly speciesist. An association of birds or deer may be more cohesive, more stable, more cooperative, more productive and less destructive of the world than an association of humans, but it is only the latter that is recognized and protected as the legal entity of “person”. The average adult of a non-human hominid genus is more intelligent than the average 3-year-old human, but the former enjoys no rights of personhood. Predicating “the right to life” on such a speciesist concept as "person" entails can never be free of the irrationality of speciesism.
Oh I would call my self a speciesist, and I don't think there is anything irrational about it. All live is precious, but human life (I believe) holds a position above all other animal life, for the reasons above (humans can act upon representations of morality). That is why humans are given greater rights then animals of their intellectual equivalents
. Actually to defend a speciesist is must harder then critisizing it (because most of our moral intuitions can be considered speciesist.)
So no exceptions in cases of rape, incest, where the woman's health is at risk, non-genetic fetal diseases or deformities (e.g., microencephaly due to maternal malnutrition)? Why should abortion be allowed for genetic microencaphaly but not for acquired microencephaly?
Oh don't get me wrong. In my initial position, the only exception that would be permitted would be if the woman's life is in danger. However, intuitively, I must also take into consideration the
predicted quality of life of the unborn child. If they have a lethal recessive disorder that would result in the child's death anyway (such that they cannot grow and life a meaningful life), then that may be grounds for abortion.
Why should abortion be allowed for genetic microencaphaly but not for acquired microencephaly?
What I mean here is the predicted health of the child (which is done through genetic testing). Obviously if the doctors can predict that the child will develop acquired microencephaly (although I'm not sure how it can be predicted before birth) then that may justify abortive actions. But, as far as I know, its not possible to do this for acquired microencephaly.
What about women and teens who are just mentally and financially unable to care for a child--e.g., a child that will certainly be born addicted to opioids?
Adoption. There are many, many couples who cannot have children and are looking to adopt. However on a wider scale, I believe there are only a very very few situations in which the ending of a life is justified. This principle you are putting forth conflicts with so much that we accept today. You are saying on the basis of a certain negative consequences (opium addiction, or bad financial environment etc) it is acceptable to end the life of the child (i.e derive them of the many many
positive experiences that life has to offer). Do you think it would be an acceptable principle to go around and euthanize drug addicts (or even possible drug addicts, who will develop a drug addiction) without their consent? Do drug addicts not deserve to live? Do they not have meaningful lives?
Yes, forced pregnancies may have side effects that are undesirable, but it would be greater moral transgression to end the life of the child simply because of these consequences and deprive them of the joys or even the very
experience of life (especially without the consent of the unborn child). As a general principle, I don't think anyone has the right to determine whether someone else's life is worth living or not (with the rare exceptions above). I think its a very very pessimistic view of life, if I may add.
I think one of the primary problems that arise in discussions about abortion is the tendency to falsely dichotomize the positions--"for abortion" vs. "against abortion". I don't know anyone who would say that abortions are perfectly acceptable at 8.9 months. I also don't know anyone who would say that abortions should never be allowed. In between those two extremes, I think there is a great deal of agreement among people.
I have a opposition to free abortion (that stems from my own understanding of the subject). I don't have a problem with people who support abortion because they don't believe the fetus has a right to life. I do have a problem with people who agree with abortion because they think it is fundamentally an issue of autonomy and not life. To me, this shows and utterly disregard of even the willingness to consider and discuss whether the fetus is a life or not. But I agree with you here. Its the two extreme positions which seem to be the most dubious.
