Haecceity
Haecceity (hɛkˈsiːɪti,_hiːk-; from the Latin haecceitas, which translates as "thisness") is a term from medieval scholastic philosophy, first coined by followers of Duns Scotus to denote a concept that he seems to have originated: the irreducible determination of a thing that makes it this particular thing. Haecceity is a person's or object's thisness, the individualising difference between the concept "a man" and the concept "Socrates" (i.e., a specific person). In modern philosophy of physics, it is sometimes referred to as primitive thisness.
Philosophy of matter
Philosophy of matter is the branch of philosophy concerned with issues surrounding the ontology, epistemology and character of matter and the material world. The word matter is derived from the Latin word materia, meaning "wood", or “timber”, in the sense "material", as distinct from "mind" or "form". The image of wood came to Latin as a calque from the ancient Greek philosophical usage of hyle (ὕλη). In ancient Greek philosophy, arche (ἀρχή) is the beginning or the first principle of the world.
