@sailboatdiaries good point on putting faith in anything. Logic, however, is not predicated on faith, but on critical thinking. As more fallacies are encountered I'll update this list. I found an amazing map a few years ago online of all the formal and informal fallacies known today, will see if I can dig it out for a future post.
You still need ethics as well, of course, but this wasn't a post about ethics. Logic gives the best method of action for an ethical goal. Solutions rarely succeed without a logical basis.
I will say this regarding my phrasing - I did it for a reason. I'm trying to convert people away from Statheism. I figured some Commandments would help the transition.
