Abstract

The metaphysical explanations of genidentity are very important both for scien-tific researches and for everyday human activities. Endurantism, perdurantism and exdurantism (stage view and point-eventism) are the standard metaphysical theo-ries, which provide descriptions and explanations of relations of change and persistence. The descriptions and explanations in question give simultaneously the truth-conditions for statements about an identity of objects, which persist and undergo changes in time.
