While history suggests that the founder of analytical philosophy, Bertrand Russell, won the fight against the idealists led by F.H. Bradley, in this instalment of our idealism series, in partnership with the Essentia Foundation, Yale philosopher Michael Della Rocca argues that Russell failed to even address Bradley’s central argument. But ignoring Bradley’s timeless message puts in serious jeopardy not only our basic understanding of ethics, but also the ultimate nature of reality itself.

In 1910, an event took place in the pages of the journal Mind that would turn out to be pivotal for the entire subsequent course of philosophy. This was a debate spread over two consecutive issues between the British philosophers F.H. Bradley and Bertrand Russell about Bradley’s version of monism and idealism. These articles had rather boring titles – Bradley’s “On Appearance, Error, and Contradiction” and Russell’s “Some Explanations in Reply to Mr. Bradley”– but the exchange proved revelatory.
