Re: Can we trust our perceptions to tell us what's real?

Because if you can’t tell the difference between two simple letters then how do you know your perception of your experiences are real? They couldn’t be fake. TimeSeeker, I think you mis-read me. I am in total agreement with your conclusion. You are preaching to the choir. Our perceptions are not tr...

Re: Can we trust our perceptions to tell us what's real?

Not so. Perceptions can never logically vouch for themselves. One perception cannot vouch for the realness of another perception. One dream cannot vouch for the realness of another dream. One hallucination cannot vouch for the realness of another hallucination. Of course they can, when they all alw...

Sorry, I don't understand what you are getting at. What is the relevance of this to "reality"? Aren't both of these B's just perceptions themselves?

Re: Can we trust our perceptions to tell us what's real?

Those perceptions are probably true/real, which all add up, together. They create a consistent, verifiable worldview. And my worldview also explains the "source" of mental impressions. Not so. Perceptions can never logically vouch for themselves. One perception cannot vouch for the realness of anot...

Re: Can we trust our perceptions to tell us what's real?

Everything I know about the world verifies that it's a real conversation; everything adds up so far. But everything that you know about the world comes from your perceptions. How do you know which perceptions are true/real? Which perceptions are telling you the truth? Which can you trust? The probl...

Re: Can we trust our perceptions to tell us what's real?

That's too vague, what are you actually asking? Are you hallucinating our conversation now?, ...or is this conversation really/actually happening? ...how do you know? ...if you are hallucinating, then would you know you are hallucinating? ...do delusional people believe they are seeing real things?...

Re: Can we trust our perceptions to tell us what's real?

OK. lets go with that assumption. It's testable. Go ahead and make an absolute claim. By giving you counter-examples to your "absolute" claim - I will demonstrate it to be probabilistic. Okay, it's a deal, here goes --- I claim (with absolute certainty!) that you will respond to this post. :wink: 8...

Re: Can we trust our perceptions to tell us what's real?

That's another distinction without a difference. No, that's another 'experience'. Suppose that I don't trust the contents of my perception. It's all a video game. And then what happens? Then you've gained a bit more knowledge about reality. Now, I re-state my AXIOM: Certainty is probabilistic. If y...

Re: Can we trust our perceptions to tell us what's real?

Yes. It's a contradiction. And? Did somebody lie to you that contradictions don't exist even though the evidence is right in front of you that they do ;) You contradict yourself, I contradict myself. And nothing happens... So the 'law' of non-contradiction is.... a lie ? Huh? Where did I say contra...

Lets go further and suppose that reality is in fact fake!
It is an illusion and it does not exist.
It is all in your head!

And then what happens?
...then you don't trust the content of your perceptions as necessarily real.

Sorry, there's no "infinite regress" here, but only "self-contradiction". Your statement defeats the very legitimacy (certainty) of your own statement.

Re: Can we trust our perceptions to tell us what's real?

I 'know' cuz -- as I say -- I'm too dumb to be imagining all of this, so it must be real, must exist outside of me, must exist independent of me. Looks can be deceiving :D . "Must exist" is not a very compelling reason. PS. I doubt you are dumb. The mere fact of knowing that you don't know, is some...
