Thank you very much for all of your helpful comments. Contrary to the criticism, I found Eddie’s comment to be quite lucid and pertinent. Eddie points to the real issue that my question addressed: the premoral status of the choice to live.
I have read the essay that Feldblum kindly pointed me to, and it went quite a ways in answering this problem. It also seems to support the idea that the choice to live is a pre-moral consideration. This does, however, create more questions for me. The pre-moral period in which one can decide whether to live, as I understand it, seems a similar device to the pre-societal “state of nature” in politics in that it may not actually exist, but is more of an expression of the initial epistemological step that must be made before one decides the appropriate political system (or in this case, the appropriate ethical code).
What I mean is this: if there is an actual “pre-moral” state, it comes before we can even speak fluently. It is a helpful to think about this state when thinking about the reasons for the ethical choice, but we are not actually in a pre-moral state when we are old enough to articulately decide whether to live.
So here is a related question: Can suicide be morally condemned? My thoughts on this are that morality does apply to this question- that it does not fall into the category of the pre-moral. Epistemically, yes, the decision to live seems to be pre-moral, but I am not sure that it follows that in practice, ethics has nothing to say about suicide. If one comes to the point of suicide, there must have been some original choice to live, and the adoption, at least in some part, of life supporting principles, because it is impossible to remain alive without some effort to remain so.
Could it be that the decision to die can be made based on a judgment of values? It seems that if all values were stripped away, value acheivement made impossible and ones life were directed to the service of evil- let us use a Nazi concentration camp as a rough example of this- then suicide could not be condemned according even to an ethics of self-interest. While it could not be condemned, it seems that it could also not be approved in this situation, because either choice is the negation of value.
Another example puts value back into the picture: an American highschool kid wants to commit suicide because he is depressed and does not think that happiness is possible. (Let us say he has just taken a class on the works of Kafka.) Surely there is some line of reasoning that could be presented to this person, culminating in a moral condemnation of his suicide. One could present the values that life can offer, and explain how death is the negation of value. Could this not be followed by something to the effect of: “Life is the standard of value you hold, and by that standard, death is not a value and the pursuit of death is not a virtue, so pursuing suicide is wrong,” as a moral condemnation of suicide in this case? With this, I woud be appealing to a standard of life already adopted by the agent, so the agent is not in a pre-moral state.
Sorry for the lengthiness, but I would be interested in your further thoughts on this matter. Thank you!
