One of the most common and widespread misconceptions is that each of us has our own definite characteristics – good, bad, clever, stupid, warm, cold, etc. But people aren’t like that. What we can say is that a person is more often good than bad, more often clever than stupid, more often warm than cold and vice versa, but it would be wrong to say about one person that he is always good or clever, or about another that he is always bad or stupid. Yet that is how we always categorize people. And that is wrong.
