Editing Sui generis (section)

==Philosophy==
[[Analytic philosophy]] often uses the expression to indicate an idea, an [[Non-physical entity|entity]], or a reality that cannot be reduced to a lower [[concept]] or included in a higher concept. [[G.&nbsp;E. Moore]], for example, refuted reductive [[ethical naturalism]] in moral theories like [[utilitarianism]] by arguing that  moral properties (like good or bad) could not be reduced to or equated with non-moral properties (like pleasure) because moral properties are sui generis. This can be seen in Moore's [[open-question argument]].<ref>{{Cite book|url=https://plato.stanford.edu/archives/sum2021/entries/moore-moral/|title=The Stanford Encyclopedia of Philosophy|editor-first=Edward N.|editor-last=Zalta|date=26 April 2021|publisher=Metaphysics Research Lab, Stanford University|via=Stanford Encyclopedia of Philosophy}}</ref><ref name=uslegal>{{cite web|title=Sui Generis Law and Legal Definition|url=https://definitions.uslegal.com/s/sui-generis/ |access-date=2 January 2020}}</ref>
