Competition is as innate to animal life as is breathing. It's naive to think we can simply ignore our drive to compete with one another, as naive as thinking we can ignore hunger thirst or sexual desire.

And yet we can reject our nature.

To what end?

If we accept the heat death of the universe and the fact nothing can go faster than light everything is bound to disappear. Trying to better Earth based life is useless. Then why bother trying to attain something higher? Just maximize your own pleasure until your conscience disappear. Suicide by psychedelic use is the only "hypersane" response.

The unvoiced assumption here is that the universe is fundamentally knowable through rational materialism.

Among the many things we've learned from science is that there are real phenomena that we cannot perceive. We use microscopes, telescopes, x-ray machines and other sensors of all kinds which create simulacra of the real phenomena which we can perceive.

Extend the analogy to our brains -- consider that there are literally thoughts we cannot think. Our brains tells us there are no thoughts we can't think, but our brains may be liars. Is there a way for our brains to grasp the literally incomprehensible?

It’s not hard philosophy but I recommend Letters to a Young Poet by Rainer Maria Rilke

“The only serious question in life is whether to kill yourself or not.” - Camus

Not everyone comes to this conclusion, one line of reasoning is: because there shouldn’t be a meaningless universe in the first place, it must actually have meaning.

The belief that the universe must have a purpose is a trap. It leads you down a particular line of reasoning that ends with you believing in a creator god (or gods), or that the universe itself is divine. You would likely also reason that you have a purpose in the universe that dictates your actions (adherence to religious dogma or doctrine). All of this is baseless and rationalized without objective evidence. Your only certain "purpose" in life is that which you, yourself make.

Yes, and everyone is free to make their purpose and choose that the universe does have meaning...

What is the purpose of this meaning for me, for my life right now? If not, than I shall not care about it. The universe can go f* itself.

I mean I can reject my nature and stop breathing. That is until I pass out and start breathing automatically. I can reject my nature and stop eating and drinking but that has swift death associated with it.

We can try and reject our nature but it seems eminently naive to me.

And yet somehow you can resist an urge to kill unknown weak stranger and taking their possession. (that's what our ancestor did, but somehow its not normal anymore).

What's your proof that this in in humanities nature? Not all actions we took during history are in humanities nature.

It seems more likely to me that humans were forced to do stuff like that due to other things in our nature like needing to eat and drink.

By the demiurge?

This comment makes no sense to me.

Gnosticism, look it up.

Yes I know what it is. I simply don't understand what that has to do with my original comment.

Some try, fewer truly succeed. It's one thing to reject your nature, it's quite another to not live in some lingering dissonance as a result.

To some degree or another, and some better than others.
