 If Pegasus existed he would indeed be in space and time, but only because the word “Pegasus” has spatio-temporal connotations, and not because “exists” has spatio-temporal connotations. If spatio-temporal reference is lacking when we affirm the existence of the cube root of 27, this is simply because a cube root is not a spatio-temporal kind of thing, and not because we are being ambiguous in our use of “exist”. (1948: 23)
