Full Idea
Applications of the principle of the indiscernibility of identicals apparently obliges us to distinguish the statue and the lump of bronze making it up.
Clarification
The principle says same things have same properties
Gist of Idea
Statues and bronze lumps have discernible differences, so can't be identical

A Reaction
In other words, statues and lumps of bronze have different properties. It is a moot point, though, whether there are any discernible differences between that statue at time t and its constituting lump of bronze at time t.
