Reddit mentions of Tetralogue: I'm Right, You're Wrong

The way that they are reacting is actually statistically demonstrated by social scientists to be the most effective way for religious parents to influence their wayward children to eventually return to religious practice as they age: http://www.christianitytoday.com/ct/2013/august-web-only/religion-runs-in-family.html

Also keep in mind the the statistical factor that is most likely to lead to a resuscitation of religious practice for a young adult who has strayed is marriage and children. The younger and less financially and socially stable you are when you have children, the more statistically likely you are to be hooked back into a religious community: http://www.christianitytoday.com/ct/2013/july-web-only/is-family-decline-behind-religious-decline.html

Just make sure that you don't become a young parent, that you seek out secular communities like the Sunday Assembly etc., and that you do your research on miracles and revelation and philosophy, critical thinking, and science in general

Try LA Paul's Transformative Experience, and maybe Ruth Chang's TED Talk on hard choices.

Also Williamson's Tetralogue is great, and Frankfurt's On Bullshit is a lot of fun, and politically relevant.

In regards to the Russel bit, I think getting into any of his technical works is a mistake for a noob, but this is necessary foundational reading for an amateur who isn't going to college for it:

In my view as an autodidact to philosophy, this was an excellent introduction. I think people really should not be reading selected specific academic works like Rem has suggested without guidance from a professor/teacher. One I've seen suggested before for a typical starting out laymen is:

My Grandma enjoyed it, she's the most educated person in the family with a Master's in English but never engaged in Philosophy before. If she can read into it amateurly and understand it at 82, no one else has got an excuse.

If people really want to dive deeper, they really should go to college, or just buy a bunch of used books and plow through them, read the IEP and SEP articles on the subjects, compare their understanding with peer-reviewed understandings, etc...
