As a tutor, I know that each child has haecceity, this-ness, and cannot be constrained by categories. Public school tried to constrain one of my students who is a genius. He is happier in homeschooling.
Haecceity is a deeply philosophical concept attributed to Scottish Catholic priest and university professor John Duns Scotus (1265/66–1308). He defined it as a non-qualitative property of a substance or thing that is responsible for its individuation and identity, such as a particular person’s unique identity. Scotus is also where the term “dunces” originated. His opponents equated Duns’ followers, who argued against Renaissance humanism, to dullards incapable of scholarship. [Modern humanism excludes God altogether.]
When I asked my genius-student what part of a person cannot be created by another person, he said, “Personality.” We were discussing humanoids, which fascinate him. A 1962 science fiction film, The Creation of the Humanoids, which I recommend, posits that the memory of a personality is all that can be placed in a humanoid.
