Popis:	In previous papers we developed two functional calculi of first order based on strict implication which we called S2 and S4. In the present paper, these systems will be extended to include a functional calculus of second order with the purpose of introducing the relation of identity of individuals.Primitive symbols. ̂ {the abstraction operator, the blank space to be replaced by an appropriate variable}.
