Hi, Mike.
I'm going to make a one-time excursion into philosophy in order to respond to some of your points. I wouldn't ordinarily do this, but I see that for you there are intellectual issues that are so tightly ingrained they need a little loosening before we can proceed. :-)
I'm
emphatically not inviting an extended philosophical discussion. That's not what we do here. If that's your preferred modality, there are plenty of other places for it.
They are thought processes all the same. However, while we say we can use these thought processes to find out whether or not apple exists, we can't use them to find out whether or not the "self" exists. Why? What is the validity distinction between a thought processed about something one hears or sees and a thought regarding logic? How then are the senses superior? I don't see how they are.
Ultimately there's no important distinction. I agree. And that lack of distinction could lead you toward concluding that the results of inferential thought
do exist or it could just as easily lead you toward concluding that sense objects (like apples)
don't exist in the way they're usually believed to.
This can potentially resolve my problem by showing how and why one can only be certain of something when sensed.
Thought stories, including logic, are a large extra step removed from sensory experience. For instance, you're basing your position on the notion that brains process sense data and thoughts, when you've never in your life experienced a brain doing anything of the sort. Nor has anyone else. Nor is it possible, even in theory, for anyone to experience a brain doing anything. You would have no concept of brains doing anything if you hadn't read about them, seen films about them, heard lectures about them, and so forth. None. That brains do the things you claim is nothing more than a set of acquired beliefs.
Now, by trying to give acquired beliefs an equal standing with direct knowledge, you're stacking the deck. You're placing the burden of proof where it doesn't belong. All of those acquired belief systems are hearsay. All of it should be considered suspect until proven otherwise. This investigation can't possibly succeed if you're not willing to subject
all your acquired beliefs to scrutiny. You said earlier that you were willing, but you're continuing to demonstrate that you're clinging to beliefs.
For instance, you probably don't believe that the moon is made of green cheese or that Santa Claus lives at the North Pole. Why not? Why are stories about brains more compelling than stories about Santa? What actually distinguishes thought stories that you consider to be statements of fact from ones that you don't? In other words, what does it mean to believe a story as opposed to disbelieving?
In the previous paragraph I've shifted from philosophy-speak to knowledge-speak. I'm not looking for a philosophical answer to those questions. I'm looking for a direct answer, and I'll show you how to go about finding one.
Let's examine a simple, neutral statement: "Phoenix is the capital of Arizona."
We could talk all day about whether that's primarily a linguistic proposition or if it deserves some level of factual interpretation. And we could talk about how we would go about verifying the statement if it's interpreted as factual. But that's not what we're going to do. We're going to look at what we mean experientially when we say "I believe that Phoenix is the capital of Arizona."
Sit quietly. Take a few deep breaths. Close your eyes. Abandon your preconceived notions.
1) Think "Phoenix is the capital of Arizona." How do you feel? (e.g. comfortable, uncomfortable, tingly, relaxed, tense...) What thoughts come up?
2) Think "Oshkosh is the capital of Arizona." How do you feel? (e.g. comfortable, uncomfortable, tingly, relaxed, tense...) What thoughts come up?
3) Imagine someone saying to you, emphatically, "Phoenix is the capital of Arizona!" How do you feel? (e.g. comfortable, uncomfortable, tingly, relaxed, tense...) What thoughts come up?
4) Imagine someone saying to you, emphatically, "Oshkosh is the capital of Arizona!" How do you feel? (e.g. comfortable, uncomfortable, tingly, relaxed, tense...) What thoughts come up?
Now do this exercise at least five more times with five different propositions. Start with simple, neutral ones and transition to ones that are more emotionally charged, like "I'm very competent at _____" or "She loves me."
Become curious, like a child. Have fun. Really sit with each one and observe your responses closely. This is an exploration!
You don't have to report all the details. I simply want to know what you discover about what you experience when you believe something compared to when you disbelieve something. What's the real difference?
And by the way, I take it you don't believe there are unicorns or dragons. So what happened to "Absence of evidence is not evidence of absence" in those cases? That's rhetorical, just something for you to consider.
With love,
Steve
