"We can't know anything!" Excuse me, how to refute this judgment philosophically?

It is hard to say whether the two answers upstairs are right or wrong, because both of them are one-sided: everything has two sides, which is only the beginning, and there will be more things with this evolution.

We can't know anything, because any "thing" and "thing" has its diversity, such as a pistol. Do you ask him if it is a good thing or a bad thing? I would say, "I don't know.

To put it simply, infinity gives birth to Tai Chi, Tai Chi gives birth to two instruments, two instruments give birth to four images, four images give birth to gossip, and gossip gives birth to everything ... To evolve with the square of the square, any kind of material or immaterial has a square meaning, and it is almost impossible for human beings to spend square time studying it, just like asking "What is the biggest integer?"

In fact, we don't need to know everything in life, just know its advantages and disadvantages and how to "face and deal with it correctly" in our position.
