You are claiming there is nothing... there is a scale...
from Something - to unsure - to nothing... Do you see this? I'm at unsure because something means we have evidence... nothing means we know for sure it's nothing, which we don't, yes there is no way for sure (except unless something came along that there is something) that there is nothing... but our intuition reflects meaning in general... we have to be taught otherwise... we were not born nihilists, we were born with a curious nature to explore whatever it is that fits ourselves.
I'm an agnostic atheist. nihilism is unnecessarily further down the line... it's like (as an example) saying there will be no way to fly (before flying came to be) It's like many things in that realm... how can you say... yeap defo nothing... I know this... it's just not true that you know it's nothing... and I don't believe that "nothing is true" it's a logical fallacy which I explained... I don't know what branch of nihilism you are but since you overlooked that statement I'm guessing you do not deny the universe... but as for purpose of the universe you reject there is any what so ever... why the universe really needs some meaning isn't of a concern to me... I don't look at life that way, there's no reason to that suites me... I wouldn't say that it's a meaningless universe, life is beautiful, full of wonderful things for me to do and please... I couldn't call it nothing... there's too much to admire worth a 1000 words a piece. If I've said something you've disagreed with here, you're probably not a true nihilist. That term "high spirit" must come from somewhere?? lol
In all without proof... something could be true up to a scaled percentage between 1-99% if we're talking about universal
(less towards imagination)... otherwise it's can be like saying you understand the universe.
Nietzsche didn't believe in a natural cause of justice and forgiveness either, he asserts revenge for the most part in his work, people make mistakes, I think utilitarianism has been the way forward, might not be perfect but it's more in the right direction.
I'm an agnostic atheist baby, well cuz there is no evidence and there is not much point looking deep into it all, really it's too big for anyone to have a real good understanding of how things came to be. <3
