Atheism is the lack of belief and faith in any gods or religions due to a lack of evidence. There are no universal or consistent expectations or beliefs beyond that in the atheist/agnostic community. However, there are common, albeit variably held and understood, thoughts, philosophies, ethics, morals, and beliefs within the atheist community. Some commonly agreed ideas and philosophies include secularism, materialism, humanism, scientific method, and the Socratic method. Morality, ethics, and beliefs are commonly understood as relative, but justified by the above ideas and philosophies.
