10 mitos - e 10 verdades - sobre o Ateísmo by Sam Harris is a 2006 essay (originally published in the Los Angeles Times) in which the author methodically refutes ten widespread misconceptions about atheism. Harris argues that atheists find deep meaning in life through relationships and lived experience, that historical atrocities attributed to atheism actually arose from dogmatic ideologies resembling religion, that atheism is not itself dogmatic but a rejection of unfounded claims, and that morality arises from human intuitions and reason rather than scripture. He also addresses links to science, openness to awe and spiritual experience without supernatural beliefs, and the distinction between consoling illusions and truth.

The essay is clear, concise, and sharply reasoned, typical of Harris’s style. It remains an effective short corrective to persistent stereotypes and serves well as an accessible introduction to contemporary atheist arguments.
