Your comment on the explanatory power of delusions made me think of the accepted axioms (postulates) of Quantum Mechanics (QM). In a way, these could be considered "Axiomatic Delusions", albeit with tremendous explanatory power, since we have accepted in these absence of other knowledge, although they've been reinforced over and over again in a plethora of experiments. A fun read on this concept: [the-sociable-solipsist.storychief.io]

Gotta go along with Groucho

If an idea, or a set of ideas, has more explanatory power than another idea or ideas, I would not call it delusional. I would call it a better understanding (presumably of the world about you) or a more useful model of reality (whatever that is).

Yes, I am a pedant when it comes to English usage, and being a pedant has both its advantages and its disadvantages. I am also blessed and cursed by having an analytical habit of mind, which is why I make a distinction between delusions and (better) understanding.

I struggle to overcome my delusions. As soon as I rid myself of one, another one pops up. There's a narrow line between delusions and aspirations, so I limit my aspirations too.

You're delusions are all your own, mine are entirely different,except where they intersect at an agreed point called shared reality..just sayin.

I suppose it depends on what your delusions are. Are they delusions or hope, and where does one end and the other begin.

Our perceptions are based on our understanding of the environment around us. Your beautiful looks can be both a blessing and a curse, cheer up you are young and full of promise. Just a little gift for you, be well

There's an oft-repeated quote from Albert Einstein that nearly everyone misinterprets, but I think it applies to what you've expressed:

“Science without religion is lame, religion without science is blind.”

This quote is generally taken out of context, but in context he's saying something similar to what you are — or something that dovetails with your idea, at least. In particular, he's using "religion" in a very specific sense: he says that there's a leap of faith that we must acknowledge that the world is indeed comprehensible and that we have the capacity to understand it through the scientific method.

What if the world is not fully comprehensible, though? What if we lack the capacity to understand? One thing that bothers me is that our observable universe might not hold the secrets to fully explain how it works, that we would need access to information contained outside of the spacetime in which we are able to exist to truly get the answers we desire.

I think about the meaningless, but justifiable question of what happened before the Big Bang. As far as we know, the conditions at the apex of the Big Bang were very similar to the conditions within a black hole, and that all of the forces and the dimensions of time and space as we know them came into existence during expansion. We can measure things as they exist within those physical parameters, but it may be that the deeper scientific secrets are forever shrouded from us because we need to have a complete understanding of something that exists outside of our universal laws and properties, of other possible universes, of a super-universe.

In essence, I am concerned that there will come a point when we've figured out as much of our universe as we can, but it will still barely scratch the surface and won't lend itself to unlocking the mysteries that we aren't even aware exist. So, in a sense I agree with you about delusion, though I wouldn't call it that exactly. I think we are perceiving accurately, with the help of instrumentation that supercedes the limits of our biological senses in myriad ways, but it may very well be that we are so limited in the scope of data, observation, experimentation, and so forth, that our understanding of the world will never achieve what our scientific leap of faith hopes for.

Everyone has them to one extent or the other

You're not delusional, you're just quirky... That's a good quality.. Learn to embrace your quirkiness

Everyone's got their biases. Better to be aware of them than to pretend they don't exist.
