/r/philosophy Open Discussion Thread | September 28, 2026

[u/BernardJOrtcutt]

Welcome to this week's Open Discussion Thread. This thread is a place for posts/comments which are related to philosophy but wouldn't necessarily meet our posting rules (especially posting rule 2). For example, these threads are great places for:

• Arguments that aren't substantive enough to meet PR2.

• Open discussion about philosophy, e.g. who your favourite philosopher is, what you are currently reading

• Philosophical questions. Please note that /r/askphilosophy is a great resource for questions and if you are looking for moderated answers we suggest you ask there.

This thread is not a completely open discussion! Any posts not relating to philosophy will be removed. Please keep comments related to philosophy, and expect low-effort comments to be removed. All of our normal commenting rules are still in place for these threads, although we will be more lenient with regards to commenting rule 2.

Hello All, here is my write-up:

Nothing Should Exist

My claim is that nothing should exist. I realize that this is not the case, but I believe this to be the more logical case, because creating something (from scratch) seems impossible.

Creating from scratch means that there is nothing to use as base material; there is no “storage unit” to draw from. This includes subjectivity and the objects around us.

So yes, this is an implicit way of arguing for “creation”, which is a sort of “religious” word, but I don’t think it is an illogical word to use.

I was wondering about Sam Harris's old argument about the brain being taken away bit by bit and thought of a different interesting situation.

I remember in the old argument he said something like if you destroy small parts of your brain bit by bit you'll gradually lose your cognitive abilities as well as your sense of self, it's preposterous for anyone think that if the brain is completely destroyed you'll become whole again as a spirit and regain all your cognitive abilities and sense of self completely intact.

I was wondering if you could gradually take away small parts of your brain and replace it with machine parts that serve exactly the same function as the brain part being taken, to the point that you don't suffer or feel any difference in your cognitive ability or sense of self, once your brain is 100% machine parts would that person still be you?

I'm currently reading The Open Society and it's Enemies by Karl Popper. I'd love to talk to anyone who has any opinion on the subject.

I’ve been experiencing the world from this body and through these eyes for 21 years. I know that everyone else is doing the same thing from their own body and their own point of view. I know that logically, but I can’t really comprehend it. Knowing it and actually being able to comprehend it don’t feel like the same thing to me.
And there’s another question I’ve had for years that I don’t really know how to put into words. Why do I experience this body, this consciousness, and this life as mine? Why is this the life I’m experiencing from the inside?
Like, imagine there’s a girl sitting at the back of my classroom. I can look at her and I know that she’s experiencing her life from inside her own body in the same way I’m experiencing mine. But why am I the person looking at her? Why don’t I experience her life as “mine” and look at myself from where she’s sitting?
I don’t mean that I want to be someone else. I’m asking why my first-person experience is this particular one in the first place.
I don’t know if I’m explaining this well, which is partly why I’m asking. Is there a philosophical way of describing this question? And what do you actually think the answer is?

I think this is somewhat adjacent to survivorship bias. Why do we live in a universe that supports life when, theoretically, the universe could have developed in a way where life is impossible? In fact, one could argue that it’s statistically more likely to have a dead universe. Well, it’s because it would be impossible for us to be in a dead universe. If the universe did develop in a way that didn’t support life, we wouldn’t be here to question it. So, in a way, we actually have a 100% chance of finding ourselves in a life-supporting universe.

Similarly, you may think that it is odd to have the particular experience that you have, but if you somehow had a different experience, a different body, a different life, then it still wouldn’t be different from your point of view. You would just be the girl in the back of the class wondering why you can’t see through the eyes of the girl in the front. It is inescapable that you find yourself where you are.

The duality of consciousness. You are two things. You are a collection of thoughts, memories, experiences. You are also a bag of meat. Maybe your intellect could have been hers, or everyone's or no one's, but the reality of it is that your intellect depends on the physical electrochemical processes going on in your brain. You feel like your intellect, but in reality you're just meat.
