Humans are herd animals. Social beings. Community is a basic need. “Resonance” is a very beautiful term used in psychology which refers to empathic resonance with other people’s feelings or thoughts. It describes the feeling of connection to a greater whole, the experience: I am not alone and isolated.
And it is this feeling that is strengthened by community. Knowing that there are other people who are connected to us through similar experiences, exchanging ideas with them, strengthens us. It gives us confidence.
