Now, in our whole discussion, I cannot recall that an Atheist has actually tried to meet this challenge.It can hardly be said that Atheists can believe in Ethics/Morals and Meaning for real.
Has anyone got an account of why, as an Atheist, he or she is obliged to believe in morality or meaning at all? Sure, we know they can practice them if they want, or they can point out that they are sociological phenomena...but this is quite different from suggesting any reason Atheism sponsors that choice.
Moreover, can they justify, from an Atheist perspective, why anyone who DOES NOT WANT to behave morally or IS NOT INCLINED to impute any kind of "meaning" to life is rationally or morally obligated to do so, on the basis of Atheism?
Or is the OP right, and Atheism is a dead stick in regard to both morals and meaning?
