There Are Many Worlds but All of Them Are Inside Ours. I often wonder what motive to a person to do what he do. How to explain that brothers who grow up into the same family, live in the same neighbourhood and study at the same school develop, as time goes by, such a diferent so-called way of life?. Whereas many persons not only make hard efforts to achive his goals working hard but also being an assess for their comunity, for instance giving back to it, others behave in a selfish way or refuse to pursue their dreams avoid outdoing themselves. People that belong to the first group are usually loved by their closers, because they contribute to make life go easier, instead of complicated it, as people who belong to the second group do. As a result, we don't take in granted that bringing up childrens in a accurately way , they end up being good citizens. It is a tough issue, which has been studied by philosophers for many years. Maybe, amount them, the Spanish one, Ortega y Gasset, sheds light on the issue when he says "Both circumstances and personality make up the human being". And adding up both of them produce an unique person. Sometimes, either a wonderful one or an awful one.
