An 'entailment' is a valid step in logical reasoning
Gist of Idea

A Reaction
A helpful definition. Not all sentences, therefore, need to have a 'logical form'. Is the logical form the same as the underlying proposition. The two must converge, given that propositions lack the ambiguity that is often found in sentences.
