AB,
Optimistic statements based on one's own personal views or wishes, not backed up by valid reasoning are just as much fallacious as statements of personal incredulity which are not backed up by intelligent reasoning.
Nope. Optimism is the hope or wish that something will turn out as someone wishes it to turn out. It's not a claim of fact. The argument from personal incredulity on the other hand is the claim that something actually
is the case, albeit based on the claimant’s inability to conceive of an alternative. You for example routinely collapse into the argument from personal incredulity fallacy because you cannot (or will not) ever engage with the explanations that falsify your notion of what is.
I have been falsely accused many times on this forum of personal incredulity…
No, you’ve been "accused" correctly of that – many, many times in fact.
…when I have offered substantial, well thought out reasons which have been dismissed by meaningless words such as "drivel", "gibberish" or "theobabble".
To my knowledge you have be never once offered a “substantial, well thought out reason” at all. No matter how many times your mistakes are explained to you, rather than engage with those explanations and attempt to rebut them you just repeat the same mistakes over and over again. Look, I’ll show you: can you think of any reason at all to justify your claim of a necessary “driver” for decision-making that isn’t:
1. Just a description of how the experience feels;
or 2. Something you really, really want to be true because it’s the cornerstone of your religious beliefs?
It’s OK, you can say it – “no” is the answer isn’t it.
And that’s your problem.
