This chapter presents a cultural-sociological analysis of Lord Bertrand Russell (1872–1970) as an archetypal example of a dramatic intellectual in the twentieth century. Following a cultural-sociological approach, I argue how collective fears and hopes, from mild to radical ones, are much more than the direct psychological and social consequence of events’ ontological, intrinsic impact. Rather, they are master stories woven with semi-autonomous cultural codes and narrations. First a prophet of the industrial Golden Age and later a prophet of the industrial Apocalypse, Russell’s binaries and master stories about science, religion, communism, the United States, nuclear bombs, and the Vietnam War are among the most prominent of the twentieth century. That the person who was, for many, the greatest herald of logic and reason in the twentieth century was also one of the most iconic prophets of an industrial Doomsday is a social fact that can only be properly understood from the point of view of cultural sociology. Despite Russell’s changes of views, I show how we can always find a common symbolic structure underpinning his diverse narratives around science, progress, and apocalypse: in different moments of the twentieth century, the whole world faces absolute evil represented by a meta-adversary, and the only way to avoid total catastrophe is by following Russell’s prophetic recipes.
