Full Idea
Not every proposition has a subject-predicate form, and so by contemporary lights Kant's definition of analyticity [predicate contained in subject] is unnatural and stifling. What of 'If it is raining now, then either it is raining or it is snowing'?

A Reaction
Only a logician would want to assert something so pointless. Kant gives a pretty good account of normal language tautologies. Still, you can't deny the point.
