Aristotle[ edit ]
Aristotle believed that objects can be described by Four causes On solving this problem. The constituent material is the material cause, the design and form of the material is the form cause, and the form cause determines what the object is. Based on the formal cause, the ship of Theseus is still the original ship, because although the materials have changed, the design of the ship - the formal cause - has not changed. From this perspective, Heraclitus stepped into the same river twice, because the form of the river has not changed. The purpose of a thing determines its purpose. The purpose of the ship of Theseus is to load and transport in myth, and to prove and commemorate Theseus in reality. Although the materials have changed, the purpose has not changed.
