Emotions

“Emotions can override…the more powerful fundamental motives that drive our lives: hunger, sex, and the will to survive. People will not eat if they think the only food available is disgusting. They may even die, although other people might consider that same food palatable. Emotion triumphs over the hunger drive! A person may never attempt sexual contact because of the interference of fear or disgust, or may never be able to complete a sexual act. Emotion triumphs over the sex drive! And despair can overwhelm even the will to live, motivating a suicide. Emotions triumph over the will to live!”
