On Suicide

The discussion in class today had me, oddly, thinking about whether we can apply non-identity problem to suicide.

This may sound far-fetched, but if you apply the non-identity problem to the concept we described in class today in which it is intrinsically better to live than not to live at all so long as you live a marginally positive life (if someone knows the exact term for it, please tell me because I couldn't find it in my notes), then you effectively cannot commit suicide so long as you are able to have children.  Essentially, my argument is that by committing suicide, an individual is depriving a possibly infinite number of descendents from existing by terminating his or her life before an offspring can be born.  Because of the infinite positive utility that could exist from him refraining from killing himself, there is no possible reason for that individual to commit suicide because there is no way their suffering is causing an infinite amount of negative utility.
