Does an invalid argument have to appear valid to qualify as a fallacy?

Philosophy professor Hans V. Hansen will consider how arguments can seem better than they are in his free public presentation, “Lookin’ good and being bad,” at 4 p.m. Wednesday, March 26, in room 209, Essex Hall.

Dr. Hansen will review and evaluate suggestions of Aristotle, Larry Powers, Sally Jackson and Douglas Walton in exploring explanations of how the appearance of goodness arises. This event is sponsored by the Centre for Research in Reasoning, Argumentation and Rhetoric.
