Daniel is joined by Dr Nathan G. Alexander, a Canadian historian who specialises in the history of race and racism as well as the history of atheism and secularisation and often combines the two, as in his recent book Race in a Godless World: Atheism, Race, and Civilization, 1850-1914- the subject of this episode. Nathan is working on a new book about the history of the word ‘racism’ itself. See his website for more details about his work, including books and articles.
