Many of Aristotle’s principles are valid for any ethics. Being human doesn’t mean simply obeying laws that come form outside, but attaining maturity. Being human means becoming as perfectly accomplished as possible. If we do not become perfectly accomplished, something is lost to the whole of humanity. For Aristotle this accomplishment derives from the exercise of the most perfect activity: that of seeking truth in all things, shunning lies and illusions, acting in accordance with justice, transcending oneself to act for the good of others in society.
