Anthropocentrism
Anthropocentric (Greek anthropos: human being) approaches can often be traced back to the Kantian tradition and Kant's ethics of autonomy. Due to their capacity to reason, human beings possess unconditional value: they are ends in themselves. Hence, every human being must respect his own value and that of other human beings, and has obligations to other human beings.
