Yes... clearly if you yourself are incapable of coming up with other reasons and dismiss reasons anyone else might offer as simply being your own reasons in disguise that conclusively proves that survival and procreation are the only reasons behind existence.blackrave said:Since when building chain of reasons and events is wrong?
For example deconstructing reasons behind our Bachelors degree took us all evening (I had an argument similar to the one we have now with my roommate)
In the end we had floor and partially walls covered with paper
Those papers were covered with web of reasons behind reasons behind reasons behind reasons, etc.
All ended up with either "Because I want to live" or "Because I want to have kids"
If you think we just stopped at this point you are wrong.
We couldn't come up with anything than emotional reasons for this ("I'm afraid of death", "I like living", etc.). Only more or less rational reason for kids was that when they'll grow up, you'll be old and they will take care for you (and that taps into "Because I want to live" reason).
When I told about this to our psychology professor and asked if he had any rational reasons for these reasons he said that we are in "the meaning of live" territory, and our guesses are as good as any other (and before you start to nitpick again, he said much more, but I'm simply providing you with basic idea).
Your professor was very correct though, albeit more friendly than I'd have been. Your reasons are indeed as good as any other, or rather as bad as any other. They're pure conjecture, incapable of being falsified or validated. Equally valid as "Because of Jesus" or "Because of Karma", and we all know how very scientific those reasons are...
