[header] How to be an atheist [title] Consider what it means to be an atheist. [step] Atheism is the lack of belief in a particular deity or higher spiritual power. Theism denotes belief in a deity-so theism is literally the absence of that. 
[substeps] Being atheistic commonly (but not always) includes disregarding traditional religious spirituality and practice in favor of a more materialistic, rationalistic, and often humanistic conception of the universe and " being ". Most atheists embrace the idea of materialism, in the philosophical sense: that nothing exists beyond the physical matter that includes your being.
