All philosophies originate from man’s curiosity of three fundamental questions: Where does the universe come from? Where does man come from? Where will man go to? All philosophies are evolved from myth, which is an imaginative and easy answer to the questions above. However, some people are not satisfied with the explanation and their further explorations create two branches of subject: Philosophy and Science. In my view, they are not conflicting but complementary. Scientists regard the universe comprehensible and separable while philosophers look at the world in a more holistic way.
Philosophy is a research to explain the law of the nature while later people develop the philosophy to understand the society and the relationship, which is a way to keep a harmonious environment.
Religion is a sub-branch of philosophy but it more serves the purpose of controlling people’s minds by telling them that the universe is created and controlled by a holy figure. Christ is a typical example. Different from Christianism, Taoism involves no cult of personality, which makes it more a traditional philosophy.
