Why must we assume this? How can we even expect consistency with the assumptions about reality we made up?
I think we all agree that the distinction is not particularly important in a practical sense, not that that was really anyone's intention. The refutation of external reality does not seem to do anything in how we proceed forward. We can call it a figment of our unconscious imagination or "real" external reality, either way we're in the same situation. We cannot know unequivocally if empiricism is valid in either case, we cannot know if there are independent agents, etc. I agree with Dave in that it becomes a matter of our inability to know if there is a meta-reality, or a meta-meta-reality, or what have you, by using the tools we have that can exclusively be used within the reality (or unconsciously imaginary system) we perceive. |

No. Our senses detect something, but whether that something is an external reality or not is the question being tested, not an assumption. Our observations are merely of what our "senses" report to our "minds" (the quotes indicating that we're not assuming that we even have brains or nerves).
And logic is definitional. We need not have any senses at all to be able to construct logic. Whether or not the simple logic we tend to use here is valid or not is entirely independent of the existence (or non-existence) of any sort of external reality. Logic is a pure abstraction.| We have to assume that the scientific method works, and that induction is valid. Those assumptions are independent of whether or not there is an external reality.

We have to assume it because induction cannot prove itself, and empirical science is based on induction.| I think we all agree that the distinction is not particularly important in a practical sense, not that that was really anyone's intention.

Right. Dude asked for a purely deductive proof of an objective reality. That's out of the question, just like all purely deductive proofs of scientific theories are impossible. Then Dude asked for positive empirical evidence of an objective reality, which is like asking for evidence that a 500x microscope is truly a 500x microscope using no tools other than the 500x microscope being tested. |

We would need a mind, though. Can you be sure that you have one (with or without quotes)? |

As a mind, I would have to say that that's the only thing I'm truly sure of. How could it be otherwise? |

How do you know that your experience of reading my post is not simply a random thought floating through somewhere? How do you know that when think back on past experiences that this was not created by a random thought drifting about? How do you know that the chronological coherence of your experiences are not simply created by a single random thought?
Ah, philosophy...
(Please substitute thought for something else if you think that we necessarily need minds to experience anything) |

Those questions are irrelevant. It doesn't matter how experiences happen or whether thoughts are random, singly or otherwise. I experience consciousness regardless of that experience's construction, coherency or medium. This is why solipsism is the default position. I know that "I" exist through the mere experience of being conscious, but can't prove that anyone or anything else exists or is aware. |

I met that someone in high school. Odd fellow. And odder still that he refused to sign or write anything in anybody's yearbooks for fear of it coming back at him negatively in the future.
