This work on the philosophy of history, by the Oxford philosopher, historian, and archaeologist R. G. Collingwood (1889-1943) also includes two conclusions written by Collingwood for lectures which were eventually revised and published as "The Idea of Nature". The cumulative effect of this labour of love, indeed, is to confound Knox's prejudice that the later years of Collingwood's writing merit suppression and to round off the project of bringing the entire gamut of Collingwood's work out of the archives and into the public domain. The result will surely be a continuing reappraisal of the only British philosopher of history whose work is still read by historians.
