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.
