Humanism split into three main branches. The orthodox branch holds that each human being is a unique individual possessing a distinctive inner voice and a never-to-be-repeated string of experiences. Every human being is a singular ray of light, which illuminates the world from a different perspective, and which adds colour, depth and meaning to the universe.
