A more thorough explanation:

Definition: Jus naturale is a philosophical system of legal and moral principles that are believed to be based on human nature and moralistic ideals of right and wrong rather than on legislation, judicial action, or statutes. It is also known as natural law.

For example, according to jus naturale, it is inherently wrong to kill another human being, regardless of whether or not it is legal or justified in certain circumstances. This principle is based on the belief that all human life is valuable and should be protected.

Another example of jus naturale is the idea that individuals have certain natural rights, such as the right to life, liberty, and property. These rights are not granted by governments or laws, but are inherent to human beings.

These examples illustrate how jus naturale is based on moral principles that are believed to be inherent to human nature, rather than on laws or regulations created by governments or other authorities.
