policy in science

The lowest level in science is to understand. It's the realm of logic of thought and humility. Science does not blind him, it makes him rich.

The second lowest level is less understood. The less understood will continue to learn until he understands, he will keep asking to get the correct understanding node.

Up another level are those who misunderstand
Misunderstanding is usually due to emotions put forward, so he did not have time to think clearly.
And when they finally understand, they usually apologize for their misunderstanding.
If not, he will rise to the highest level of knowledge.

The highest level of science is to fail to understand
Failure to understand this is usually more because of arrogance. Because he felt knowledgeable, he was no longer willing to accept knowledge from others.
No longer want to receive input from anyone (either advice or advice), or picky just want to receive knowledge (advice) from which he likes it, not the science delivered, but who delivered.

Closed his heart
Closed his mind
Closed his hearing
Closed logic

He always felt enough with his own opinion.
Worse yet he did not realize that his failing understanding, the laughingstock of the understood.
She stays with her, and she is proud of her misunderstandings.

Do you understand that you are at the bottom and fail to understand at the highest level?
What is not upside down?

People are getting more and more down to earth, down, down. He became wise, because at last he knew that in fact a great deal of knowledge he had not known, he felt as if he did not know anything.
He continues to receive knowledge, wherever that science comes from.
He did not see who was speaking, but he saw what was being said.
