Consilience. It's really that simple.
This has so far been a bunch of silly navel-gazing. Some of these philosophers, who operated in times without understand how many branches of science could be brought to bear on their navel gazing. And Half-Life has not matured in thought since then.
But here it is in a nutshell: If all you've got is your mind and my mind and there is no physical world between them, then you will not see the agreement in experience, measurement, action, reaction, etc. Take an example as easy as the game of GeoCaching. A person puts an object in a spot, and 100 other people completely unrelated - find it. Indeed in one case we came across one in the woods without even looking and later were able to find the people who, "in their minds" had put it "there".
That's a simple example, but there are more and significantly more complex examples.
Your thought exercise requires that very stiff boundaries are set in order for it to work. You can't look too far, you can't look too hard, or your philosophical mind experiment falls apart. Deluding yourself by excluding evidence is cute, when you're doing a little navel gazing, but is utterly worthless in understanding the world.
It's a clever linguistic trick if you're trying desperately to convince yourself that a god exists, but you are nevertheless deluding yourself by scribing your box so tightly that it guarantees your desired outcome in your head - while the rest of the universe goes on without you.
Man, you guys REALLY don't understand Berkeley's point. Pain is only in the mind. All sensations are in the mind.
Oh we understand his point. We conclude that he is deluded and wrong.
You REALLY don't understand that we are refuting his point, not misunderstanding it.
My first-person experience may be limited to my mind but such strict empiricism isn't necessary. I can extrapolate from my experiences to a world.
Now, the external world... does it have to be observed by God to exist? You keep saying "Berkeley! Berkeley!" but haven't explained his ideas and what's so very fucking convincing about them.
The talk is about "ideas" and "objects" and about how objects don't fit into minds so only ideas are there. Then there's the stuff about how only immaterial ideas exist outside our private minds too (else they can't get into our minds at all). And since they're ideas outside the human's mind they must be in the mind of God. What's not addressed is energy. If Berkeley were alive today and trying to refute materialism, he'd have to say how energy isn't registered by sense organs and translated into "ideas" (ie, objects of perception) in our minds, thus explaining why it's not necessary that objects be ideas (the stuff of minds) because sensory perception can translate objects to "the stuff of minds".
What do you mean energy isn't registered by sense organs? Energy is still something that you are using a mind to explain.
Everything is only known through minds. So yes, the external world exists, but it exists because God is always perceiving it.
Claim asserted without evidence.
As abbadon tells you, you have not explained why this Berkeley's ideas are plausible. You have merely asserted them. It's not even clear that you understand them. Nay, it's pretty clear that you do not understand them.
Which - in the end - is consistent with all of your claims about gods and bibles and the like. Empty assertions and proclamations without logic or evidence.
The materialist must explain how they know the external world exists independently of minds. Immaterialists don't have that problem because we don't assume things can exist independently of minds.
LOL listen to yourself. "We don't need logic because we assume we don't need it, therefore logic is wrong."
Immaterialism is the default,
Assertion without evidence. Silly assertion with not even a shred of logic.
"The default is to believe in magic."
Duuuude.
materialism requires that extra step of evidence, which Berkeley argued was not needed. I suppose you could say using Occam's razor, the default should be immaterialism.
Assuming you understand Berkeley correctly (not currently supported) you're saying you like his argument because he claims
it's easier to make shit up than to prove it?
THAT'S your argument?
