Full Idea
The Representational account of validity says an argument is valid if there is no situation where the premises are true and the conclusion false. The Interpretation account says the premises are true and conclusion false under no interpretations.
Gist of Idea
Validity is where either the situation or the interpretation blocks true premises and false conclusion

A Reaction
My immediate instinct is to want logic to be about situations, rather than interpretations. Situations are more about thought, where interpretations are more about language. I think our account of logic should have some applicability to animals.
