Thread: Strictly, we know absolutely nothing, even the former sentence

Ok, this is a very strict form of "knowing" something.

It is a bit hard to explain, so I will try my best.

Suppose there is a batch of color on the wall, it is the color yellow. A man comes up and says, do you know of any single reason that this color can not be yellow? The man staring at the wall says no. The other man says, do you know if such a reason could exist? The first man says, "I do not know", then you philosophically can not say that this is the color yellow, says the other man.

Agree or disagree.

Having this type of mindset, we then know absolutely nothing. Even the former sentence.
