\"There is but one truly philosophical problem, and that is suicide.\"
 

I tend to agree with this statement. What is the point of debating morality if you have not first determined that life is actually worth living?

Re: \"There is but one truly philosophical problem, and that is suicide
 

That doesn't make suicide the one philosophical problem, just the first one with which one must deal. And that issue arises later in life. Not really contemplatable very early in life.

I would agree that life is a prerequisite, so far as I'm aware, for any other reasoning. However, so is a self, a consciousness, which may or may not require life.
