If you take the logical positist point of view then a strike is a strike regardless of who is behind the plate. The empirical definition of the strike zone must be used. If you take a more postmodernist pragmatic perspective then the strike zone is an interpretation of the experience of the person behind the plate. Hermenuetics would provide the basis for adjusting the zone to fit the situation such as age group or if the game is a blow out. I believe most umpires are postmodernists allowing the zone to vary but the zone itself has some empirical basis.
