Looking for an intelligent, rational discussion re atheism

[MSizer]

Epistemology is a huge topic. To consider an idea "true" IMHO is when that idea generates the feeling of certitude to a high enough degree that it influences my actions. In other words I "feel" like the idea, a mental image, faithfully reflects reality somehow. The problem is that something can feel true whether it is or not. That's why critical thinking is so important IMO. Since our feelings of certitude are not connected to each others', what one considers proof is not to another. Is that meaningful?
