Single Idea 22127

[filed under theme 9. Objects / A. Existence of Objects / 5. Individuation / d. Individuation by haecceity ]

Full Idea

Rejecting the standard views that essences are individuated by either actual existence, quantity or matter, Scotus said that the principle of individuation is a further substantial difference added to the species - the so-called haecceitas or 'thisness'.

Gist of Idea

Scotus said a substantial principle of individuation [haecceitas] was needed for an essence

Source

report of John Duns Scotus (works [1301]) by Stephen D. Dumont - Duns Scotus p.206

A Reaction

[Scotus seldom referred to 'haecceitas'] I suppose essences have prior existence, but are too generic, so something must fix an essence as pertaining to this particular object. Is the haecceitas part of the essence, or of the particular?
