"The violence in the world comes about because we human beings are forever creating barriers between men who are like us and men who are not like us"

This quote by Edmund Leach speaks to the origin of violence in the world: our propensity to develop divisions between individuals who are like us and those who are not. This can manifest in many types, such as bigotry, sexism, and other types of discrimination. By producing these barriers, we are basically producing an "us vs. them" mentality, which can lead to displeasure and even violence. This is why it is so crucial to recognize our resemblances and accept our differences. We need to strive to create a world where everyone is respected and accepted, regardless of their background or beliefs. Only then can we truly create a world without violence and hatred.
