The Humanists of Greater Portland is offering a free 6-week class/discussion group on the topic of logical fallacies, starting Jan. 13th, 2013. This Vancouver discussion group is not a co-sponsor, but it is listed here as it may be of interest to people of all belief systems (theist, atheist, etc.). The atmosphere is intended to be neutral, so all will feel welcomed. Attend as many, or few, of the sessions that you desire.
