@conference{223, author = {Julian Chingoma and Tommie Meyer}, title = {Forrester{\textquoteright}s paradox using typicality}, abstract = {Deontic logic is a logic often used to formalise scenarios in the legal domain. Within the legal domain there are many exceptions and conflicting obligations. This motivates the enrichment of deontic logic with a notion of typicality which is based on defeasibility, with defeasibility allowing for reasoning about exceptions. Propositional Typicality Logic (PTL) is a logic that employs typicality. Deontic paradoxes are often used to examine logic systems as they provide undesirable results even if the scenarios seem intuitive. Forrester{\textquoteright}s paradox is one of the most famous of these paradoxes. This paper shows that PTL can be used to represent and reason with Forrester{\textquoteright}s paradox in such a way as to block undesirable conclusions without sacrificing desirable deontic properties.}, year = {2019}, journal = {Forum for Artificial Intelligence Research}, chapter = {220-231}, month = {03/12-06/12}, publisher = {CEUR}, isbn = {1613-0073}, url = {http://ceur-ws.org/Vol-2540/FAIR2019_paper_54.pdf}, }
