Answer:
Positive law.
Step-by-step explanation:
In the 1800's Sean Weatherby owned a plantation in Georgia. He also legally owned 20 slaves to help him work the plantation. He treated the slaves very well providing them with adequate housing and food and he believed he had not violated any ethical standards. Based on this situation, the type of ethical belief he exhibited is a positive law.
The theory of positive law states that decisions made by any individual should be with respect to the fact that, whether the action or decision made is legal or not.
In this scenario, slavery was legal and such Sean Weatherby exhibited positive law.
