Explanation

Natural law is a concept that refers to the opinion that emanates from reason and the rights-based on human nature. This concept was originated in ancient Greece when Plato and Aristotle published their works "Republic and Laws" and "Nicomachean Ethics" respectively. In them, they propose ideas related to natural justice, a concept that refers to the existence of a natural law that is "everywhere" without being determined by the thought or action of an individual or group. However, Aristotle states that natural laws is discovered through reason and the intellect. On the other hand, in ancient Rome, Cicero established that the educated man discovers the law through his intelligence, and it allows him to know the correct behavior and avoid misconduct by saying "it is the mind and reason of the intelligent man, the standard by which they are measured justice and injustice ".
