... The existential quantification of P(x) is the proposition: “There exists at least one x in the universe of discourse such that P(x) is true.” x P(x) reads “for some x, P(x)” or “There exists x, P(x) is True” x P(x) is TRUE means there is an x in UoD(x) for which P(x) is true. ...

... true. By construction of S, we have p(k) is true for all k < m0, including m0-1. Therefore by the second part of the hypothesis for either (I1) or (I2), p(m0) must be true. This is a contradiction ( p(m0 ) p(m0 ) ) and there is no such set S. if (I1) then (W) and if (I2) then (W): Clearly a subse ...
