While transcribing some stuff out of the Additiones secundi libri (compiled by William of Alnwick from the Oxford and Paris lectures of Scotus), I came across the following comment about the relation of essence and existence, a doctrine of paramount iportance in Thomism, but less so in Scotism.
Additiones II d. 16 q. 1: "esse est actus intrinsecus essentiae idem sibi realiter non ab ea progrediens"
"'to be' is an act intrinsic to essence, really the same as it, not coming forth from it"
