I heard this mentioned on The Atheist Experience #764 this morning. I think it pretty much says what needs to be said. I hesitate to call it a creed – I hate the connotation. It’s more of an explanation really.
Skepticism is my nature
Free-thought is my methodology
Agnosticism is my conclusion
Atheism is my opinion
Humanitarianism is my motivation
Perhaps The Articles of Reason. It sounds nice. I like it. I’ll stick with that.
