A more thorough explanation:

Definition: Positivistic is an adjective that describes something related to legal positivism. Legal positivism is a theory that suggests that legal rules are only valid because they are created by a political authority or accepted by a society, not because they are based on morality or natural law.

For example, legal positivists believe that a law is valid simply because it was created by a government or other political authority, regardless of whether it is morally right or wrong. This means that a law that is considered unjust or immoral can still be considered valid if it was created by a legitimate authority.

Legal positivism has been supported by scholars such as H.L.A. Hart, who argued that the law should be studied as a social phenomenon rather than as a moral or philosophical concept.

Overall, positivistic refers to a way of thinking that emphasizes the importance of legal rules and institutions, rather than moral or philosophical principles.
