There Are No Facts. Only Opinions. . I'm glad this has not devolved (yet) into blind insults. That's good.
My argument appears to be changing, or at least that's how it would appear to others, but that's because I'm presenting it in installments. Also, I'm not entirely sure how to summarize my idea, so I'll attack this communication problem from another angle- by providing the context and the background for my odd claims- so at least others will know where I'm coming from.
Imagine this: you're in a dark, abandoned house. Your best friend, hiding in a corner, jumps in front of you, and you scream like a little girl. The casual relationship in this scenario appears to be obvious: "your best friend surprised you in a scary environment. Thus you were scared and screamed."
But it's not that simple. What actually happened on a biological level was more like this:
"Sounds and sights from the environment [best friend jumping in front of you] triggered the neurons in your eyes to send signals to neurons in the back and side lobes of your brain. These neurons then triggered the subsystems in your brain involved with "fight / flee." Your body jumped back because, again, the fight/flee subsystems sent signals to the rest of your body triggering a physical reaction. This event is then, somehow, imprinted in the various subsystems of your brain involved with memory, which is why, later, when your friends tease you about it, you get angry." Etc. etc. .
In other words, when "you" jump back and scream in response to a scary event, it's not as simple as it seems. What's actually happening is that your brain is responding to itself, in response to external cues from the environment. Or more specifically: subsystems in your brain responded to other subsystems in your brain, which then activated various other parts of your body, which is why you were scared. When you look back at the event, what's happening on a biological level is that executive neural networks in your brain are modifying/recalling the neural networks involved with memory. Somehow. No one knows the details, but what I've provided here is a reasonable sketch.
Why did I write all this? It's to point out that "facts" don't exist in a vacuum. "Facts" are memories stored (somehow) in human brains. When you recall a "fact", you're recalling a "memory"- the result of some physical process in your brain. If you didn't have a brain, you wouldn't be able to recall 'facts.' If everyone lost their brains, then everyone would have also lost their 'facts,' which means there will be no 'facts' anymore.
Etc. etc. '
