Abstract

The notion of "possible worlds" apparently raised by Leibnitz for the first time, is recently put into account for the role it plays in the semantics of modal logic.
 The most significant theories on possible worlds are categorized into two general types,i.e.actualism and possiblilism about each of which there are various versions. In this survey, the versions of D.Lewis and kripke on possiblilismm and those of R.Stalnaker, R.Chisolm, R.Adams, and A.Plantinga on actualism are examined and criticized.
