 We begin with an essence-to-grounding principle, one specifying a potential entailment from truths about essence to truths about what grounds what. According to Rosen (2010), for any x, if it’s essential to x that P, then [It’s essential to x that P] grounds \([P]\) (see also Dasgupta 2016 and Kment 2014: Ch. 6). Rosen points out that this principle, if true, may clarify the grounding profile of certain universal facts. For example, perhaps [It’s essential to triangularity that all triangles have three sides] grounds [All triangles have three sides]. (See Glazier 2017 and Zylstra 2019b for critical discussion.)
