Do we know everything?

Do we know everything to be a judge of what is right and what is wrong?

• The night sky, we see lights, apparently the light is only like 1% of the darkness, but what is in the darkness or what is darkness that we cannot see?  How are we to know everything?
• The brain is 2% of the total weight of the body, the body thinks and believes it knows all about the 96% body, refused to listen to the body when the body tries to talk to the mind, does the brain really know everything?

If we want to be better, is it not better to be humble and listen to learn?

Until we know everything, then we can to judge what is right and what is wrong, don’t you think?
