Has anyone who embraced the philosophy of skepticism ever converted to a religion?

They are already religious from my perspective.

Religion has absolutely nothing to do with God or spirituality from my perspective, it is a set of habits that are consistent.

Skepticism, Atheistic and Theist are all religious in one way or another.

Example, lets take Catholicism. Now, at face value that is not my personal definition of religious. At a Catholic mass, the people are instructed to stand, sit, kneel, eat communion, hail Mary, etc... all of these practices are done religiously, in order, the same time every time.

Example: a Skeptic will usually become skeptical of a new idea or suggestion on action religiously because s/he is skeptical.

Example: Yahoo answers will award me 2 points religiously when I submit this answer.

Perhaps to Buddhism, but they wouldn't follow mainstream Buddhism because they'd be too skeptical of the supernatural claims and cultural influences to take it as it is. However I've met spiritual people who call themselves atheist/non-religious while doing buddhist meditation as well as yoga on a heightened level that many religious followers haven't acheived; if Buddhism's a philosophy non-religion religion then I'd say I've met some, in a way.

From what I've seen, those who allege that they became theists after being atheist did nothing of the sort. They were never atheists - they simply hadn't previously worked out what they believed.

Only during Grateful Dead Concerts...

Skeptics are people who are SO open-minded their brain falls out.

no one that did such well. St. Aquinus did but not well.
