In his 1927 book The Analysis of Matter, Bertrand Russell proposed a novel approach to the mind-body problem. Arthur Eddington, in his Gifford lectures of the same year, independently expressed very similar thoughts (published in Eddington 1928).[15] Remarkably this approach was almost completely forgotten about for much of the twentieth century. However, there has recently been a revival of interest in this approach, resulting in a Russell-inspired view that has become known as “Russellian monism”.
