Does everyone like being alive? Happy people surely do, almost by definition. If you’re happy, then you are apparently having a good time. Nobody wants to stop having a good time, otherwise they wouldn’t call it “good” in the first place. If you wanted it to stop, then you would call it a bad time, and you wouldn’t describe yourself as happy.
Some good times burn the fuse and we know they are temporary. You can be having a good time at a bar but also want to go home because you feel yourself getting tired and run down, you feel the night slipping away, and that it is time to go home. It doesn’t mean that you wanted the good time to stop. It simply means that the availability of that good time had passed. If you want to avoid having a really bad time the next day, you better get your self home.
With Christmas approaching, many people will both love and hate celebrating the holidays over the next few weeks. They will love it because it is emotional in a good way, they will hate it because it is emotionally exhausting. It will be the best of times and the worst of times. Some will be very sad to see it end, others will count themselves lucky to have survived it. What makes us want to end an experience is bad feelings, what makes us want to continue experience is good feelings.
It is common to feel tired of life, but I have a hard time believing that people ever actually *want* to die. Rather, my suspicion is people simply want to stop having a bad experience, and when life becomes a continuous, uninterrupted bad experience, they think they want to end life, when they really just want to end the bad experience–sometimes immediately. Like staying too late at a bar, we begin to feel an exhaustion set in, and being able to get away becomes more and more attractive.
If both going to the bar and leaving the bar, rushing into the holidays and then desperately wishing them to be over, are both motivated by a desire to increase good experience and decrease bad experience, then the constant essence of our behavior would seem to include wanting to have as good experiences as possible. We pursue happiness constantly, as much as we perceive as being available, and when anyone says they wish they were dead, they really mean they want to leave their current bad experience and go to a good, or at least better, experience.
The problem with desiring death is it implies desiring the end of existence, or oblivion. Because oblivion is the absence of experience, we cannot imagine it, so we cannot feel in anticipating death any pain. Death is expected to be pain-free. If we are in pain in life, then we can think that we desire death, which is to say to simply be pain-free. But having a pain-free experience is impossible if we cease to exist. In other words, when we reason that death is desirable because it is pain-free, we are being non-sensical — failing to realize that by anticipating less pain “there” we are assuming a continued existence in death. We might kill ourselves to escape experiencing pain, but it is not and cannot be to escape life or to “be” dead. Therefore, no one desires to die, and everyone desires happiness and perpetual existence, i.e. immortality.
