Ha Ha! I love this.
Let's imagine that we conclude life and the Universe are devoid of all meaning, that we will soon cease to exist forevermore, that the human race will eventually cease to exist and that might not take too long, that the Universe itself will, at some far distant time, be wholly devoid of any life and nothing will ever happen again, that our existence is pure happenstance and our lives and the Universe are ultimately absurd.
We can believe all this. But we nevertheless find ourselves miraculously alive, having experiences now. Exploring the world, having experiences, wondering what it all means, enjoying this very brief flicker of existence. So life is still very much worth living.
But, I nevertheless still think that people don't really grok how radical this is. They prefer not to think about it, to lose themselves in the trivialities of existence. And, perhaps, that's just as well if they truly do believe their lives and the Universe are ultimately absurd. That it is a tale told by an idiot, full of sound and fury, signifying nothing.
I just took a pause here and reread my previous paragraph. It sounds like I emphasise with the guy on the left. Not at all! If, contrary to my beliefs, I were an atheist and naturalist, I would very much agree with the guy in the tree. But, regardless of our beliefs here. Regardless of our ultimate fate. Regardless of what we ultimately are. Regardless if the Universe came into being by happenstance or is a result of something more mysterious. It still remains life is an adventure to be experienced and cherished.
