Happy means the joy that comes when a request or wish is fulfilled. For science, it’s different. It is the superiority of positive thoughts and emotions over the individual’s life. Information affects people in two ways. One of them is positive, the other one is negative. It is important what the information is about it. Like, if it comes as bad information, it will make you sad, but if it’s good news, it will make you happy. According to Socrates, the purpose of life and the highest good that everyone pursues throughout life is happiness. The way to happiness is information; information about people and life, because correct information shows the true way for people to take correct actions for their job or life.
It’s different for knowledgeable people because as information increases, awareness also increases, and the more carefully you look at the world, it will change your perspective on everything.
