Theory of projection (goodman"s new riddle of induction): problem with the logic part of o&l, bug blood example: Strong evidence written in chinese and weak evidence written in english. Is the wisdom of investment based on the language the evidence comes in: must distinguish generalizations that inductive evidence should be able to support from those it should not be able to support: Accidental generalizations (economic recessions occur during sun spots vs. law-like.
