Universal Moral Grammar (UMG) Ontology
Updated: Sep 27, 2022
In his book Moral Minds, Marc Hauser hypothesized the existence of what he termed a Universal Moral Grammar (UMG):
I argue that our moral faculty is equipped with a universal moral grammar, a toolkit for building specific moral systems. Once we have acquired our culture’s specific moral norms… we judge whether actions are permissible, obligatory, or forbidden, without conscious reasoning and without explicit access to the underlying principles.
I have developed an ontology that is a formal model of a UMG. In September of 2018 I presented this paper on the ontology at the Semantics 2018 conference in Vienna:
This page consists of additional materials to support that paper such as a link to the actual ontology as well as a much extended version of the Semantics 2018 paper. I’m also pleased to say that the UMG ontology below won the award for Best Vocabulary at the Semantics 2018 Vocabulary Carnival.
Here is a PDF of the presentation that I gave at the Semantics 2018 Conference: Semantics 2018 Presentation
Here is the OWL version of the ontology: UMG-Ontology-8-30-18.OWL
This is a significantly longer version of the Semantics 2018 paper: UMG Extended Paper
Here is a link to the ontology in Web Protege: UMG Ontology in Web Protege

You need to setup the account and login before you click on the WebProtege link to the ontology. Also, note that if you wish to download the ontology from WebProtege you can do that. Click on the History icon (the far right one in the group starting with Classes, Properties, etc.) This will show a list of revisions. Select the latest revision (there should be a little grey icon in the right corner of the history like "R1") and then select the option "Download revision 1" from the pop-up menu.
