Natural language does not possess a sentential negation-operator.
Gist of Idea
Natural language 'not' doesn't apply to sentences
Source

A Reaction
This is a criticism of Strawson, who criticises logic for not following natural language, but does it himself with negation. In the question of how language and logic connect, this idea seems important. Term Logic aims to get closer to natural language.
