Wonder

1) the mind's model of reality is relative, but we can only ever model reality as a whole inside of our own minds - reality as a whole is unknowable, even in principle.

This doesn't mean we can't know, for sure, quite a lot about specific subsets of reality: "is there milk in the fridge?" has a good, precise answer, but "what's it all about then?" does not.

But our answers to "what's it all out then?" shape our ideas about our lives, which in turn shape our behavior. So our answers to these "questions without answers" actually heavily impact our lives over the long run.

2) Meaningness is an aesthetic value in that it is perceived in things and situations, and can be created intentionally at times. The sense of purpose and significance, of rightness and beauty, may be fleeting, but they are as objectively real as musical harmony but with this principle applied across the entire field of awareness. A similarly broad concept might be "well-proportioned", which can apply to almost anything in almost any area, and "you know it when you see it."

How's that?

Especially at turning points in life, people ask questions like:

Is there any purpose at all in living? Or is everything completely pointless? What am I supposed to do? How can I choose among the many ways I could spend the rest of my life? Does everyone’s life have the same purpose, or does everyone have their own? Where does purpose come from? Does it have some ultimate source, or is it just a personal invention?

These seem like questions without answers. Or, alternatively, the correct answer is whatever you decide it to be.

Imagine a dog or dolphin or octopus asking this question. We'd think: "Why are you asking such questions? You're a dog/dolphin/octopus. You do dog/dolphin/octopus things. That's all you're supposed to do."

Isn't it the same with humans? We do human things. Take care of ourselves and our loved ones. Help others who need help. Try to better ourselves.

Does it need to be any more complex than that?

In all seriousness, that is becoming one of my guiding principles (along with "divisions into categories are models"), so maybe I should pay more attention to this dude, except that he really is kind of hard to follow sometimes...

I beg to differ. The correct answer is whatever you decide it to be given the nature of reality. The whatever you decide it to be leads to subjectivism, which means you can do whatever you want. But clearly some activities are better for you as an individual compared to others.

eg. Working a job is better than robbing a bank. You know this intuitively based on years of internal reasoning, now think of why? Try to make that logic explicit.

We, as humans, are special in that we have a very high degree of choice compared to rest of animal kingdom. The most extreme form of it is that can choose to end our life (i.e. commit suicide), and no animal can do that.

So then, what are human things? Why is "taking care of ourselves and our loved ones, helping others in need, better ourselves" good choices? I am not saying these are bad choices. They are very good indeed. Again, you know this intuitively based on years of internal reasoning, now think of why? Try to make that logic explicit.

There is a very simple framework to come to these conclusions. Unfortunately, a large population does not come to the same conclusions as you.
