SUMMARY

This discussion centers on the philosophical inquiry into the nature of existence, particularly the existence of the self and external reality. Participants argue that while one can assert their own existence through thought processes, proving the existence of external matter, such as a keyboard or an apple, presents a significant challenge. Key points include the assertion that matter exists independently of consciousness and the philosophical implications of Descartes' skepticism regarding sensory perception. The conversation emphasizes that existence is an absolute, independent of individual perception or belief.

PREREQUISITES
  • Understanding of basic philosophical concepts, particularly existentialism and skepticism.
  • Familiarity with Descartes' First Meditation and the concept of universal doubt.
  • Knowledge of the distinction between subjective and objective reality.
  • Awareness of logical fallacies, particularly circular reasoning.
NEXT STEPS
  • Study Descartes' philosophy, focusing on the implications of "Cogito, ergo sum."
  • Explore the concept of materialism and its philosophical underpinnings.
  • Research the role of consciousness in perception and reality, including theories from neuroscience.
  • Examine logical fallacies in philosophical arguments, particularly circular reasoning and the burden of proof.
USEFUL FOR

Philosophers, students of philosophy, and anyone interested in existential questions about reality and perception will benefit from this discussion.

the reason i was arguing the existence of matter was to get ur13 to think differently about existence. I originally asked if you could prove you exist and then the whole issue of "i think therefore I am" came up, so I was arguing that maybe there is no thought and that its just the compilation of particles creating some sort of thought. The main thing I'm asking is whether or not we exist, but that always leads to thought so I brought the question of what is thought. Sorry for any confusion, I hope this makes sense. So prove you exist, and if you use thought as an argument, prove you have thought.

well to prove existence one does not need to use thought but if you could
[1] have thought of self or being a single entity then you are done...
so to define thought regardless of if it is byproduct or not OR whether you exist in our PHYSICS world or MATRIX world...I'd say fif you can create the feeling of "I" then you have thought...

[2] thus comes the definition of feeling or sensation...or ability to see or feel ones self move...ah its great to watch little kids first learning the function of a mirror...my niece took 2 tries to understand it but it was cute as she tried to touch the image.

so how would you define feeling or sensation. I don't know i guess it would be the ability to react under contact. this may be also be leading to the definition of instinct...

...i'll think more on my definitions but how would you define those 3 terms.

But how do you define what thought is? What I'm trying to say is how do you know your thoughts arnt a compilation of tiny particles all working together to create some bigger thought. Its hard to explain but it makes sense in my mind. At least what I think is my mind.

How do you define what anything is. Anyway point being, even if my thoughts are tiny particles working together to create something, which is what a thought is, the particles have to exist somewhere to create the thought, so therefore if the thought exist, then you do. Consciousness is happening now, so something must exist.
I think the question of whether or not we really exist isn't a great one. Even if the world and universe we live in, doesn't exist. Something must, or else we wouldn't have any thoughts or have our own made up world or whatever. Its pretty obvious, that something exists. And no one ask me to prove it. Because i can only prove to myself that i exist using logic. You can do it for youself too. Whether anything else does, well yes i guess it does. My mind exist, and in that mind exists other things. Whether the world around me is apart of my mind or not is a different thing.
