untermenche.You have moved a little. You appear to acknowledge thoughts are a function of brain. Something you resisted over on science.
I do believe the external world exists. It is not possible to live effectively without believing it.
But it is just a belief. A belief most do not ever question. The unexamined life is common.
All I know are my experiences.
And it is possible that my experiences are all that exist. Since they are experiences and not objects.
If it is all subjective, how can your views be any more valid than mine?
If you have no argument to dispute them.
Explain to me how observing a car crash is subjective, the context of the OP is what is objective evidence. Our discussion is a bit of topic.
It's my OP and I am the one saying what I think objective evidence is.
And nobody has moved me from my position.
What is called "objective" evidence is the experience of an agreement on subjective experience.
This scientist experiences a measurement of 3 pounds. This other scientist experiences the same measurement.
It is all subjective experience and reports of subjective experience.
But if it is agreement of subjective experience between the right two individuals, trustworthy I suppose with a laugh, it is called "objective" evidence.
Two people witness a crash. The car is destroyed and on fire, how can they disagree on the crash they both witnessed?
Everything you "see" is an experience.
It looks to me you are just talking about "seeing" something.
That is an experience. Vision is an experience.
You do not see the car. My belief is you see something the brain has created for you to experience.
But that is my belief.
All we really have are experiences and the beliefs we have about them.
And my beliefs could be wrong. They are only beliefs.
