Single Idea 4201

[from 'A Survey of Metaphysics' by E.J. Lowe, in 7. Existence / B. Change in Existence / 1. Nature of Change ]

Full Idea

Qualitative change is seen as either (i) 'Presentism' - 'a is F now', or (ii) 'relational properties' - 'a is F-at-t', or (iii) 'temporal parts' - 'a-at-t is F', or (iv) 'adverbial' - 'a is-a-t F'.

Clarification

a is an object, t is a time, and F is a property or predicate

Gist of Idea

Four theories of qualitative change are 'a is F now', or 'a is F-at-t', or 'a-at-t is F', or 'a is-at-t F'

A Reaction

The traditional view would let a stay the same over time, and change its property (ii). Lewis favours (iii). My suspicion is that thinking collapses if you abandon the tradtional view.
