Christopher Eric Hitchens was a British author, journalist and atheist . Author of 18 books on faith, culture, politics, and literature, he was born and educated in Britain, graduating in the 1970s from Oxford with a degree in Philosophy, Politics and Economics. In the early 1980s, he emigrated to the United States and wrote for The Nation and Vanity Fair. Known as "one of the 'four horsemen'" of New Atheism, he gained prominence as a columnist and speaker. His epistemological razor, which states that "what can be asserted without evidence can also be dismissed without evidence", is still of mark in philosophy and law.
