“No way of thinking or doing, however ancient, can be trusted without proof.”
-Henry David Thoreau,
Walden
"A way of seeing is also a way of not seeing."
-Kenneth Burke.
Obviously has no understanding of presuppositionalism.
This falls under the, "Don't let anyone tell you what to think," category. Or to put it another way: it's self cancelling.
But how do you define proof? Everyone has their own definition, and for most, the burden of proof is much lower, when it "proves" something they already endorse. Prove to me how gay marriage, for example, belittles hetero marriage? It won't take much for the zealot but I likely have a higher burden.
But how do you define proof?
It would be all too easy to drag out passages from the ocean of great epistemological treatise, but this quote is short and provides deep insight:
A proof is a proof. What kind of a proof? It's a proof. A proof is a proof. And when you have a good proof, it's because it's proven. [Jean Chretien]
bc, you're talking about the amount of evidence that it would take to convince someone to either believe a new position or change their current position on some issue. This may be - but doesn't necesarily have to be - done through a logical proof.
The "proof" in the quote (I believe) is what Arne was getting at. It's not a threshold for belief, but rather, part of a rational and logical system to evaluate statements by looking at evidence.
I thought it was nonbelievers, Don (anyway, thats what the guy on the corner yells at me when I walk past even though Im pretty sure that hes had no revelation as to what I believe maybe its my deodorant).
City? In the suburbs actually, and guy on the corner is my neighbor Albert. Hes currently mad at me because he thinks Im watering the tree in his front yard when hes not looking (which I am trees need water in the summer). Im not sure how it came to name-calling though.
"Why is he mad at you for watering his trees?"
How did I get from Thoreau to here...my apologies.
What would Thoreau say today? Would he be concerned about the limits of logical truths, as demonstrated by Gdel's Incompleteness Theorems? Or maybe he'd be more concerned with the psychology of trust and influence? Is Thoreau a skeptic?
