At the beginning of this young community, I thought it might be helpful to make a clear distinction between the definitions as they differ greatly in their explainability. Contrary to some opinions that can be heared, the statements a) there are one/more divine beings and b) no divine beings exist are logically equivalent.
I’m not really a fan of the binary agnostic or gnostic distinctions of atheism. What does it mean to “know”, exactly? To be absolutely, 100% convinced beyond the shadow of any doubt, or to conclude that there isn’t any evidence of God? There’s quite a bit of room for disagreement over how we might use the term.
I think something like the Dawkins scale is much better, as it shows a gradation of conviction. I think most atheists would probably fall on 5 or 6 on the scale rather than 7/7.
I’m really sorry that the graphic I chose seems to be misleading. Basically, it should represent a matrix (similar to a political spectrum) which contrasts the conviction with its strength. Your scale would correspond to an inverted parabola. I like the descriptions of this list very much. Maybe tomorrow I will find a better graphic ;)
