Marcel Mauss was a French sociologist who wrote a lot about people and their culture. He looked at how people interact with each other, trade things, and even how they give gifts. He believed that people have a natural way of being nice to each other through gifts, and that this can even happen without money or anything else of value. Mauss studied the cultures of many different groups of people, from the traditional societies of tribes in New Guinea to modern societies in Europe. His work showed that in all different kinds of societies, people have a tendency to give gifts and do nice things for each other, even when there is no benefit for them. He also said that when people give something for free, it often makes people feel good about themselves and their relationship with other people. So Marcel Mauss was an important thinker who taught us about the power of being kind to each other!
