Etymology

Haecceity is a Latin neologism formed as an abstract noun derived from the demonstrative pronoun "haec(ce)", meaning "this (very)" (feminine singular) or "these (very)" (feminine or neuter plural). It is apparently formed on the model of another (much older) neologism, viz. "qui(d)ditas" ("whatness"), which is a

Haecceity vs. quiddity

quiddity In scholastic philosophy, "quiddity" (; Latin: ''quidditas'') was another term for the essence of an object, literally its "whatness" or "what it is". Etymology The term "quiddity" derives from the Latin word ''quidditas'', which was used by the ...

or hypokeimenon. However, in proper philosophical usage these terms have not only distinct but opposite meanings.

Haecceity in scholasticism

Duns Scotus makes the following distinction: In Scotism and the scholastic usage in general, therefore, "haecceity" properly means the irreducible individuating

differentia In scholastic logic, differentia is one of the predicables. It is that part of a definition which is predicable in a given genus only of the definiendum; or the corresponding " metaphysical part" of the object. Origin Plato implicitly employed ...

which together with the specific essence (i.e. quiddity) constitutes the individual (or the individual essence), in analogy to the way specific differentia combined with the genus (or generic essence) constitutes the species (or specific essence). Haecceity differs, however, from the specific differentia, by not having any conceptually specifiable content: it does not add any further specification to the whatness of a thing but merely determines it to be a particular unrepeatable instance of the kind specified by the quiddity. This is connected with Aristotle's notion that an individual cannot be defined. Individuals are more perfect than the specific essence and thus have not solely a higher degree of unity, but also a greater degree of truth and goodness. God multiplied individuals to communicate to them His goodness and beatitude.

Haecceity in anglophone philosophy

In analytical philosophy, the meaning of "haecceity" shifted somewhat.

Charles Sanders Peirce Charles Sanders Peirce ( ; September 10, 1839 – April 19, 1914) was an American philosopher, logician, mathematician and scientist who is sometimes known as "the father of pragmatism". Educated as a chemist and employed as a scientist for ...

used the term as a non-descriptive reference to an individual. Alvin Plantinga and other analytical philosophers used "haecceity" in the sense of "individual essence". The "haecceity" of analytical philosophers thus comprises not only the individuating differentia (the scholastic hacceity) but the entire essential determination of an individual (i.e., including that which the scholastics would call its quiddity).

Haecceity in sociology and continental philosophy

Harold Garfinkel, the founder of

ethnomethodology Ethnomethodology is the study of how social order is produced in and through processes of social interaction.Garfinkel, H. (1974) 'The origins of the term ethnomethodology', in R.Turner (Ed.) Ethnomethodology, Penguin, Harmondsworth, pp 15–18. I ...

, used the term "haecceity", to emphasize the unavoidable and irremediable indexical character of any expression, behavior or situation. For Garfinkel indexicality was not a problem. He treated the haecceities and contingencies of social practices as a resource for making sense together. In contrast to theoretical generalizations, Garfinkel introduced "haecceities" in "Parson's Plenum" (1988), to indicate the importance of the infinite contingencies in both situations and practices for the local accomplishment of social order. According to Garfinkel, members display and produce the social order they refer to within the setting that they contribute to. The study of practical action and situations in their "haecceities" — aimed at disclosing the ordinary, ongoing social order that is constructed by the members' practices — is the work of ethnomethodology. Garfinkel described ethnomethodological studies as investigations of "haecceities", i.e., Gilles Deleuze uses the term in a different way to denote entities that exist on the plane of immanence. The usage was likely chosen in line with his esoteric concept of difference and individuation, and critique of object-centered

. Michael Lynch (1991) described the ontological production of objects in the natural sciences as "assemblages of haecceities", thereby offering an alternate reading of Deleuze and Guattari's (1980) discussion of "memories of haecceity" in the light of Garfinkel's treatment of "haecceity".
