Abstract
Our approach to a construction of semantics for modal calculi consists in interpretation of modal statement in terms of necessary and possible truths as well as in terms of necessary and possible falsity. It supposes also some actual and logical necessity, chance and possibility. In this paper there are given semantics for a number of calculi of actual and logical modalities. We have constructed the calculi of actual modalities in the beginning of the seventies
