Similarly, for someone who refuses to think in terms of aggregate demand, an aggregate demand shortfall is inconceivable.

Sometimes we see people who view themselves as "pro-Say's Law" arguing that "Keynesians are wrong about growth being demand driver: supply has to come before demand." This is odd, to me, because, while I think it is questionable whether Say's Law always holds (unless one states it as a tautology, in which case, it will always "hold," but trivially so), it certainly is based on a genuine insight: people supply commodities on the market in order to demand others: supply IS demand, just seen from a different perspective.
