We present a general schema of easy normalization proofs for ÿnite systems S like ÿrst-order arithmetic or subsystems of analysis, which have good inÿnitary counterparts S∞. We consider a new system S + ∞ with essentially the same rules as S∞ but di erent derivable objects: a derivation d ∈ S + ∞ of
