⁂ The rare second and third volumes of Whitehead and Russell's brilliant but failed attempt to place mathematics on a logical basis. The influence of this extraordinarily complex work was nevertheless profound, ultimately transforming the studies of logic, set theory and linguistic analysis. The first volume was printed in a run of 750 copies but sold poorly due largely to its complexity. This led to reduced runs of 500 copies for the two later volumes resulting in their present rarity.
