Journal editor: Our treasurer advises that Support because of our precarious financial situation, Support we should change from a paper version to an online version only if doing so will not increase the cost of publication. ███ ████ ██ ██████████ ████ █ █████ ███████ ██ ██ ██████ ███████ ██ █████ ████████ ████ ███ ██████████ ██ █████ ███ ████ ███ █████ ██ ████ █████ ███ ██ ██████ ████████ █████ █ ██████████ ███ ██████ ██ █████ ███ █████ ██ ███████████ ███ █████ ██ ███ ██████ ██████ ████ ███ █████████ ██ ██████ ██ ██████ ██████ ██ ██ ██████ ████████
The argument can be diagrammed as follows:
The journal editor confuses necessary and sufficient conditions. He takes a necessary condition of changing from a paper version as a sufficient condition for making the change. We know that we should make the change only if it won’t increase the cost of publication, and the necessary condition (/increase cost of publication) is confirmed, but confirming a necessary condition doesn’t trigger the sufficient condition. From the information given, we cannot conclude that we should make the change.
