Does Intelligence Lessen Happiness?

The higher intelligence,the more happiness? This is definitely a debatable issue. Ernest Hemingway said, "Happiness in intelligent people is the rarest thing I know." Based on this, we come to such a conclusion that, the more intelligent the less happy. Is this conclusion correct? An obvious fact is, people with high intelligence usually be more frequently rewarded for their important contributions, and they can always find joy in their own way. How can we believe they are less happy than common people? In my point of view, Hemingway neglected the difference between knowledge and intelligence, so he confused the two to draw the above-mentioned conclusion. His conclusion is quite far from the truth, or at least, inaccurate. A more precise expression should be, happiness in knowledgeable people is the rarest thing I know.
Why Hemingway’s saying should be adjust like that? I’ll explain. According to explanations given by the Oxford Advanced Learner Dictionary, intelligence is the power of learning, understanding and reasoning, while knowledge stands for all that a person knows, or familiarity gained by experience. Coupled with happiness, which is usually defined as a state of mind or feeling characterized by contentment, love, satisfaction, pleasure, or joy, we can reason that there’s no antithesis between intelligence and happiness, and high intelligence is more likely to have a positive effect on attaining happiness. As for most people, it is just the rare happy experiences of life that makes happiness so precious. So, the more a person knows, the more common his experiences are, when he can only feel happy at a higher threshold, his happiness slips away from him. For these reasons above, we can conclude that the more knowledgeable a man is, the greater chance he losses happiness, and that’s why I revised Hemingway’s saying into” Happiness in knowledgeable people is the rarest thing I know.”
