Human nature refers to the characteristics of mankind. This means ways of thinking, feeling and acting which humans have naturally.
What these characteristics are, what causes them and how fixed human nature is, are good questions. They among the oldest and most important questions in western philosophy. These questions affect ethics, politics and theology. Human nature is a source of advice on how to live well, but it also puts limits and obstacles on living a good life.
The complex implications of such questions are also dealt with in art and literature, while the humanities inquire into human nature, and what it means to be human.[1]
