Full Idea
A better proposal for a formal logic closer to natural language would be one that had a negation-operator only for (simple) predicates.

A Reaction
Dummett observes that classical formal logic was never intended to be close to natural language. Term logic does have that aim, but the meta-question is whether that end is desirable, and why.
