haecceities

One can apparently hold that transworld identities may be ˜bare™ without holding that they are constituted by any properties at all, even unanalysable haecceities

Transworld Identity Mackie, Penelope 2006

There are infinite of these subtle trifles, and others more subtle than these, of notions, relations, instants, formalities, quiddities, haecceities, which no one can perceive without a Lynceus whose eyes could look through a stone wall and discover those things through the thickest darkness that never were.

The Praise of Folly Desiderius Erasmus 1502

The criticism of our time ... is indissociable from an investigation and experience of its transcendental field (s), of the (impersonal) tendencies and haecceities which traverse it, as well as the potentialities, utopian ones perhaps, with which our present can be composed.
