@freemo You can never be 100% certain that what you see is a physical reality. It might be an optical illusion. But if you run around refusing to believe the evidence of your own lyin’ eyes, you might be a leftist.

It is quite possible to make a mistake in math too. That doesn’t change the underlying (abstract in the case of math) reality. It just means having the humility to admit when you are wrong.
