Ad hominem links

If I do end up becoming a philosophy professor, I think one of my big goals in intro classes will be trying to teach students to identify common fallacies… and tell when a particular fallacy isn’t being committed. To that end, I think the following links would make a pretty good reading list on the topic of ad hominem:

Paper on Plantinga and classical foundationalism
