Thinking is something you choose to do， just as a fish choose to live in water． To be human is to be always thinking． But thinking may come naturally without your knowing how you do it． Thinking about thinking is the key to critical thinking． When you think critically， you take control of your own ideas， or you might be controlled by others' ideas． Indeed， critical thinking is at the heart of education．

The word "critical" here has a special meaning． It doesn't mean taking one opinion against another， as when someone criticizes （批评） another person for doing something wrong． The nature of critical thinking is thinking beyond （超出） what you easily see ﹣ beyond the pictures on TV or reports in newspapers．

What are critical thinkers like？ If you want to know about life and hope to dig deeper into it， you are a critical thinker． If you find pleasure in deep thinking about different ideas， characters， and facts， you are a critical thinker．

Critical thinking is a deep and careful thinking． It takes time， and doesn't go with the fast speed in today's world． If you are among people who believe speed is a measure of intelligence （智力测量）， you may learn something new from a story about Albert Einstein． The first time Hoffman， a well﹣known scientist， talked with Einstein about his work， he was too nervous to speak． But Einstein got him relaxed right away by saying， "Please go slowly． I don't understand things quickly．"
