Well, no, there doesn’t. Some people simply want to live because life, overally, is fun. They don’t have any god reason to feel like life is good, they just do.
I can assure you, the only universals are beyond your control. They’re simply not worth worrying about.
I can only say that I have yet to see any evidence that makes an argument for purpose compelling. Maybe there is a “guiding logic”, but if you ever find it, you might be the first one to do so.
Maybe that’s a consensus answer, but it’s not the only one.
For me, I have no idea if life has meaning or not. I have to operate under the assumption there may be no logically sound reason for being, except this: I’m greedy. I want to enjoy myself. I like to eat, sleep, have sex, travel, work, not work, etc. I have the capacity to derive pleasure from such activities, and this pleasure is a strong incentive to keep doing them. In other words, being alive gives me more opportunity to be happy, so far as I know, than not being alive. If, when I’m not alive, my mind is destroyed and I no longer have thought of any kind, then my living state is all I will ever know. It’s my one shot. If I lose my life, I lose everything, both the good and the bad.
Again, it sounds to me as if you’ve got a run-of-the-mill case of major depressive disorder. I won’t say you’re not thinking rationally, because I think depressed people actually sometimes have a more rational view of the world than not-depressed people. You may be recognizing quite rightly that there is no point in any of it. You’re just worm food in the end, and as one of billions who happen to be alive right now, your contribution to the big picture may not add up to much more than a bucket of snot. There may be no benevolent God who wants good things for you, and if you stick it out to the end, will deliver you to Paradise. There’s really nothing stopping you from not living except your own animal fear of death, which you may see as a major annoyance at this point, more than anything.
I’m saying you may very well be 100% correct. In fact, I tend to think you are (though many would disagree with me most stridently). You know what? I don’t care. I really don’t. Why? I don’t know. I’m lucky. I’ve found or been given the things I need to have what we call generally good emotions, and hence being alive is its own reward. If I become depressed in the future, I will doubtless feel like my prior bout of happiness was a joke, some kind of illusion. Probably, it was. Well, so what? It was better than being depressed, so if I come to that point I remember that things can be different and work hard at doing whatever I need to do to my brain to get back to a euthymic state. Chances are, it won’t be so much through logic as through conditioning and chemicals.
Trust me: These Big Questions just don’t matter all that much. They’re certainly worth thinking about in an academic sort of way, but they’re not essential at all. Not knowing if there is a purpose is 100% OK, and no one’s happiness, as far as I can tell, is predecated on knowing the Answers, even if they’re knowable at all.
