The Law of Reversibility is an ethical principle governing the application of technology in the Continuation. It states that a technology should not be implemented unless its effects can be reversed. It is identified as being of Ránlan origin but is internationally accepted in some form by all Nations except the Samas.
In its absolute form, the Law of Reversibility states that a technology should not be used unless its effects can be reversed. This applies to almost all human actions of significant human impact since humans innately function using technologies (agricultural, architectural, etc.). For example, a forest should not be felled unless it can be replanted to form effectively the same ecosystem.
It is broadly understood, however, that this absolute is not attainable. In literal terms, almost no act can be reversed. A replanted forest will, by definition, not be exactly the same as its predecessor.
Practical technological ethics, therefore, is concerned with determining how closely an implementation must follow the Law of Reversibility in order to be considered acceptable. This judgment differs vastly in different Nations and different time periods. The Ránlans and Kiris are the most rigorous in its application.
The Law of Reversibility is considered one of the core ethical principles that facilitates technological and social stability and sustainability in the Continuation.
