Made me think of a Uni course on Thomas Aquinas from eons ago. I'll have to go back and check but I think:
"An essence of an individual is a property possessed by it and necessarily implying any of its properties"
could have come from Aquinas' "Being and Essence".
And - forgive me it has been eons - didn't Wittgenstein deal with this time of formulation showing you could in parallel construct its opposite.
