Many of us still tend to think that emotions can affect reasonablethought，and sometimes land us in trouble.But in recent years psychologists have taken quite a different view.Keith Oatley，Professor of Psychology at Glasgow University，is involved in the research which shows the fundamental importance of emotions.
He believes we_are_very_ambivalent_about_them：we think of our emotions as being unreasonable，but we also consider them as essential to being human.For example，Mr Spock，a character in the television series Star Trek，is superintelligent and he has no emotions at all.However，he is never made captain of the spaceship.Maybe，this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.
As Professor Oatley points out，our emotions have very important functions，for example，fear.If we cross the road and a car approaches，we usually stop moving or step back.We stop what we are doing，check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which，on average，help preserve our safety.
