Meta Ontology

Traditionally, this puzzle has been solved in various ways. Aristotle, for example, distinguished between ''accidental'' and ''essential'' changes. Accidental changes are ones that don't result in a change in an objects' identity after the change, such as when a house is painted, or one's hair turns gray, etc. Aristotle thought of these as changes in the accidental properties of a thing. Essential changes, by contrast, are those which don't preserve the identity of the object when it changes, such as when a house burns to the ground and becomes ashes, or when someone dies. Armed with these distinctions, Aristotle would then say that, in the case of accidental changes, (1) and (2) are both false---a changing thing can really change one of its ''accidental properties'' and yet literally remain one and the same thing before and after the change
