John Smith wrote:
Perhaps?

"As far as the laws of mathematics refer to reality, they are not
certain; as far as they are certain, they do not refer to
reality."--Albert Einstein

And, I humbly propose:

"Too often, the ignorant are quick to conceal their ignorance in
complexity not well grasped by common men."--John Smith

I think that's true. I like it.

I like this one too:

"He who knows, does not speak. He who speaks, does not know."
