The irrationality of a thing is no argument against its existence, rather a condition of it.
Friedrich Nietzsche
As I think about this quote I am struck by the ways in which it might be interpreted.
First let me give you some context on my perspective. The source is the theory of creationism. I recently heard an argument related to the Big Bang theory claiming that whatever precipitated the Big Bang had to be “placed“ there or initiated by “someone.” This information is second-hand so you will have to excuse any inaccuracy in the exact argument but I think the sentiment carries through. In its basic form the argument seems to say that if there is truth to the Big Bang theory then it had to have been kicked off by something intelligent, presumably God.
In my attempt not to belabor this point let me tie this right back to the prevailing quote. In short, I would argue that the essence of the quote is to say that just because the theory is incomprehensible by our current understanding is not evidence of intelligent design. It just means we haven’t figure it out yet. The incomprehensible nature of a theory that there was a dense mass in the universe that expanded to create all that we know and see is an aspect of the theory. Just because it is incomprehensible does not mean that the theory is disproven. It is also not proof that there was intelligence behind it.
On the flip side I could see someone making the claim that the incomprehensible nature does not disprove the possibility of intelligent design. I would agree. Just because God is incomprehensible does not mean there is no God. I would agree with this too.
My only point here is to lean into this quote that struck me in relation to a recent discussion I caught wind of. If you do not understand a thing then that lack of understanding does not automatically generate proof that it is or is not so. It just means that the difficulty in understanding is a nature of the thing you are seeking to understand.
