Since developing his theory of liquid modernity in the late 1990s – which describes our age as one in which “all agreements are temporary, fleeting, and valid only until further notice” – he has become a leading figure in the field of sociology.

A. The question of identity has changed from being something you are born with to a task: you have to create your own community. But communities aren’t created, and you either have one or you don’t. What the social networks can create is a substitute. The difference between a community and a network is that you belong to a community, but a network belongs to you. You feel in control. You can add friends if you wish, you can delete them if you wish. You are in control of the important people to whom you relate. People feel a little better as a result, because loneliness, abandonment, is the great fear in our individualist age. But it’s so easy to add or remove friends on the internet that people fail to learn the real social skills, which you need when you go to the street, when you go to your workplace, where you find lots of people who you need to enter into sensible interaction with. Pope Francis, who is a great man, gave his first interview after being elected to Eugenio Scalfari, an Italian journalist who is also a self-proclaimed atheist. It was a sign: real dialogue isn’t about talking to people who believe the same things as you. Social media don’t teach us to dialogue because it is so easy to avoid controversy… But most people use social media not to unite, not to open their horizons wider, but on the contrary, to cut themselves a comfort zone where the only sounds they hear are the echoes of their own voice, where the only things they see are the reflections of their own face. Social media are very useful, they provide pleasure, but they are a trap.
