there are no mathematicians reading.

logic is a study of literature only, no different to knowing vast

journals of legal precedents, the entire art history of the Incubus

period, the works of Shakespear or illustrated Medical Journals.

You are talking to Clayton's Arts Graduates who wish to further the

'study' of logic, which opposes the _application_ of logic.
