This volume covers the period from the beginning of Whitehead and Russell's work on Volume 2 of the Principles of Mathematics to the critical discovery of the theory of descriptions in 1905. The volume contains a large number of unpublished manuscripts which illustrate Russell's often unsuccessful struggles with logical paradoxes, as he tries out one foundational scheme after another.
