Sorry for the delay in replying, I'm very busy at the moment.

Wait, wait. You might be taking that line out of context. This is advice Feynman was giving his students, ie "let's just go through the curriculum and not waste time with the perceived implications of undead cats, cos this ain't Philosophy 101." I very much doubt Feynman or any scientist would be giving his peers advice like that.
And you base this statement on what evidence precisely? This is not just advice he gave to his students, it was advice he gave to
everyone and which he often repeated at public lectures. And I am quite certain that he
didn't mean anything like your alleged context. You only have to look at something like the Douglas Robb Memorial Lectures and you'll see exactly what context he said this in.

It is cheating to not even try to understand it, and doubly cheating to appeal to authority to justify it. That way lies woo.
What appeal to authority? I gave an example of a physicist who claimed that there was no need to worry about understanding something that seemed intractable. What was important was to accept what the evidence showed regardless of whether it was understandable or not. My point was that some members of the scientific community see no problem in the fact that something is not understood and that they don't necessarily waste their time trying to make sense of something that
seems senseless. Instead they operate with the data they have and
hope that new data will arise which will provide further insight. Feynman was not alone in this view and he wasn't shouted out of the scientific community for expressing it, because it is a prevalent view. And the only reason I mentioned Feynman at all was because I specifically remebered him saying it.
I never said that he said that nobody should ever not try to understand it. Please look at what I actually wrote.
And, an "appeal to authority" is a logical fallacy which I did not make. Referring to an authority is not a fallacy of "appeal to authority" unless one uses it to avoid arguing a point - which I didn't.

Irrationality doesn't mean going against common sense. So-called "common" so-called "sense" can be deeply irrational. QM has rules, despite looking to the layperson like freaky sci-fi. However, it's sci and not fi. It allows for testable predictions. Religion doesn't have any rules that 3 random people can agree upon. Therefore it is irrational and not just in appearance.
I didn't say that it did. Again, please read what I actually wrote. I agree that religion is irrational. It's what I've been saying all along. Maybe we're getting tied up in words here. Let's break it down into logical bites:
1. If religion
is irrational, then it can't be "false" because the logical judgement of "false" is inapplicable to things that are irrational because logic doesn't encompass the irrational.
2. If religion really is "false" then it must be rational.
3. Some people say science must be true because it is rational.
4. When science appears to be irrational some people still say it must be true
despite the fact of that appearance.
5. The reason why some people say that religion is "false" is
because it appears irrational.
Points 1 and 2 are contradictory. Points 2 and 3 are contradictory. Points 4 and 5 are contradictory. Draw your own conclusions what that says about the rationality of some of the arguments used against religion.

But I didn't define anything as unknowable. I said that we would never be able to know everything, but all that means is there will always be a lot of unknown. Not the same thing at all. I don't believe we will ever reach a point where we can't know anymore. We can only say for sure that something is unknowable (by us) when our species dies and therefore stops investigating, before researching it. But saying that something is a priori unknowable? No.
I've explained this in other posts. Maybe I expressed myself badly. I say that there are certain things which are simply not within the domain of "knowledge". For example, you can know
about something, you can't directly, personally
experience all things. Experience itself is "unknowable", you either experience something directly or you don't, but knowing
about something is never a substitute for the actual experience of something. Experience itself cannot be conveyed by knowledge and is therefore
a priori, "unknowable".

No I don't agree. Lots of people have been predicting that sort of thing ever since Democritus (the guy who coined the term "atom"), but it hasn't happened yet. And there's no particular reason why it should.
So you propose that we can continue to break things down into smaller units without limit. Do you agree that if there is no limit we will end up with an infinite number of things? And do you believe that anyone can "know" an infinite number of things?
It is not a question of what I "predict" (I haven't made any predictions!) it's a question of logic that either there is a limit or not. I don't know either way, but in any event I believe that if there
is a limit then the thing at the end of that limit will be "unknowable" in and of itself. And if there is no limit, we will end up with an infinite number of things which by virtue of the fact they are infinite in number we will not be able to know.

If something is unknown, then obviously we can't presently understand it. But that doesn't mean we never will.
To me, that is tantamount to saying that a good enough map
of the territory can possibly one day
be the territory. To me, that is an error of logic.
