Okay.
As short as possible.
I will explain the world. - The problem is that it is in part in a sense self-referring, because I do it. So we do it with science. Problem solved, right?
Well, no!

So here is one way to do it without any reasoning/justification but just where it apparently ends:
There are almost always 3 aspects/factors/categories/concepts at play:
Objective, inter-subjective, subjective.
Someone - process - something (e.g. I have an experience)
It must be independent of humans - we must agree - it must make sense to me.
Physical, social, mind.
Same, similar, different.
Time, place, property.
Past, present, future.
And so on.
There is more, but if you learn to spot those in a debate, you will notice that we all do them. Just with some variation.
So back to my post with Gould about science, cognitive relativism and the problem of rational objective justification, because that is what we are playing. I can't do it for all aspects of the world, if I have to be intellectual honest, so I do what seems to be real to me. I state what is at play and if it is objective, inter-subjective and/or subjective.
