Abstract
I review some of the difficulties associated with chiral symmetry in t he context of a lattice regulator. I discuss the structure of Wilson F ermions when the hopping parameter is in the vicinity of its critical value. Here one flavor contrasts sharply with the case of more, where a residual chiral symmetry survives anomalies. I briefly discuss the s urface mode approach, the use of mirror Fermions to cancel anomalies, and finally speculate on the problems with lattice versions of the sta ndard model.
