Interesting thread. Since I studied all sorts of physical sciences, and also several kinds of philosophy, I want to add my two cents. Philosophy has several sub-categories; namely “metaphysics”, “epistemology” and “ethics” (sometimes even aethetics).
Metaphysics deals with “existence”, in other words it deals with “what exists”?
Epistemology deals with knowledge, in other words: “how do we know something”?
Ethics deals with “ought” statements, “how should we behave”?
This is basic philosophy 101. Many people are not aware of it.
If one believes in some “supernatural”, or some “god” of “God” then one is a theist. If one lacks such a belief, then one is an “atheist”. Theist and atheist are metaphysical positions. Gnostic and agnostic deals with knowledge, so these are epistemological positions. One can be any of the four possibilities: “gnostic theist”, “agnostic theist”, “gnostic atheist” and “agnostic atheist”.
The word “god” designates anything supernatural, without any special attributes. Usually the upper case “God” designates the Christian concept of god, which has a plethora of other attributes. Now, why does one not believe in a “god” or “God” is secondary. Some people have never heard of this concept. Others may have heard it, but are unable to comprehend it. (I once met someone who was unable to conceptualize negative numbers. And I am serious.) And then there are people, who heard of the god-concept, who understand it, but find it nonsensical, or contradictory. These are all atheists.
Atheism is a purely metaphysical stance. It has no bearing on ethics. There have been very good atheists and very bad ones. There have been very good theists and very bad ones. It is not a good idea to try to draw some conclusion from one’s philosophical stance. About as bad as trying to draw conclusions from the person’s skin pigmentation.
This is still philosophy 101. I hope no one will consider this post non-charitable.
Oh, and this whole thread should really be in the philosophy sub-forum.
