Weyl's 1939 AMS address, I believe [I've quoted Weyl from that for
other purposes, not this one, but (albeit fallibly) recall Weyl
mentions this -- a fishy calculating technique in search of an
algebraic "foundation") sorry I don't have access to the
Gessamm.Abhandl to check. But instead of 'symbolic method' perhaps
it is 'calculus of finite differences' or 'umbral calculus of finite
I also suspect that 'the warhorse of...' is one of Rota's not
uncommon hyperbolic "paraphrases".
